1.0 SCOPE
1.1 GENERAL
The City of Richmond’s Official Community Plan (OCP) includes a target to reduce Richmond’s community
greenhouse gas emissions 80% below 2007 levels by 2050. Richmond’s Community Energy and
Emissions Plan (CEEP) identifies that to reach this target will require near universal adoption of zero
carbon vehicles by the 2040s. The CEEP includes Strategy 7 to “Promote Low Carbon Vehicles”, and
actions pursuant to this strategy.
The following report addresses Action 18 of the CEEP, which states that the City of Richmond (The City)
will “set minimum requirements for EV charging infrastructure in new developments”, as part of an
objective to reduce energy use and greenhouse gas (GHG) emissions. Accordingly, the City is currently re-
evaluating policies to improve the provision of electric vehicle (EV) infrastructure in new developments, to
better enable wide-spread adoption.
Multi Unit Residential Building (MURB) construction represents 58% (24,360 units) of the projected
increase in residential dwellings from 2011 to 2041, and is the focus of this report. MURB’s inherently
include the greatest barriers to EV adoption due to the challenges associated with common property.
Community charging infrastructure deployment, which is also a fundamental element in the holistic
approach to the provision of EV infrastructure is not addressed in the analysis.
The report presents the results of an analysis of EV charging infrastructure requirements for Council’s
Consideration. The assessment included:
· Development of definitions for charging infrastructure requirements;
· Recommendation of mechanisms to better ensure effective implementation of EVSE in new strata
developments;
· Assessment of costs and benefits of different EV infrastructure requirements.
The intent of the assessment was to identify reasonable, cost effective measures, to achieve the greatest
value for money, with consideration afforded to both developers and EV owners, whilst remaining
cognizant of the fundamental objective to better enable wide-spread adoption.
The following sections provide the results of the assessment for each of the major items indicated above.

2.0 DEFINING EV INFRASTRUCTURE REQUIREMENTS AND TECHNOLOGIES
2.1 GENERAL
Definitions for key EV infrastructure configurations are provided in the following sub-sections. Appendix J
includes definitions for other terminology used in this report.
2.2 INFRASTRUCTURE DEFINITIONS
The following definitions for EV infrastructure requirements are recommended.
· “EVSE (Electric Vehicle Supply Equipment) installed”: All infrastructure required for charging of an
electrical vehicle (EV), including all electrical equipment (including metering), cabling and associated
raceways, and connections, and Level 2 EVSE equipment permanently installed.
· “Energized”: All infrastructure required for charging of an electric vehicle (EV), including all electrical
equipment (including metering), cabling and associated raceways, and connections, with exception of
the Level 2 EVSE equipment.
· “Partial EV infrastructure” (note: not recommended for inclusion in policy): All infrastructure required
for charging of an electric vehicle (EV), including all electrical equipment (including metering), cabling
and associated raceways, and connections, up to the provisional branch panelboard locations, minus
the feeder cabling to the panelboards. Raceways for the feeder cabling to the provisional panelboard
locations would be included as part of the “Partial EV infrastructure”. The branch panelboards and
associated feeder cabling, branch cabling and associated raceways, and connections to EVSE’s would
be installed at a later-date.
Although “Partial EV infrastructure” configurations were assessed, it is not recommended for inclusion in
City regulation, as detailed in Section 3.1. Refer to single line diagrams (Appendix D) for further details of
the components of the EV infrastructure.
2.3 “LOAD MANAGEMENT” AND “LOAD SHARING”
Load management and load sharing are EVSE control technologies that reduce peak power demand and
improve utilization of EV charging systems, thereby reducing electrical infrastructure costs. The
technologies also provide the capability to control the time of use, which may be utilized in reducing the
impact on the Utility’s system.
Terminology utilized in this report includes:
· “Load management”: Control of the current drawn by the EVSE, at the main switchboard of the
building.

Page 3
AES Engineering Ltd. 1330 Granville Street, Vancouver, BC, Canada V6Z 1M7 P 604.569.6500 F 604.569.6501
· “Load sharing”: Control of the current drawn by multiple EVSE on a single circuit, to ensure the
capacity of the circuit is not exceeded, and that maximum charging is achieved at each EVSE based
on the available capacity.
A number of EV charging service providers offer EVSE with load management and/or load sharing
functionality. One business model that has been established is to provide EVSE equipment capable of load
management and load sharing, as well as metering EV electricity consumption to allow for reconciliation
of building electrical costs. Providers offering these “smart charging” services in the market today typically
charge a service fee that is paid by the EV owner. This arrangement is assumed in the life cycle costing in
Appendix A. However, some EVSE providers are emerging that offer EVSE capable of load management
and/or sharing that are not based on such a subscription model, and could result in reduced costs for end
users.
3.0 RECOMMENDATIONS ON POLICY FOR EV INFRASTRUCTURE
3.1 GENERAL
If the City intends for all residents of new multifamily developments to have access to “at home” EV
charging, it is recommended that City policy specify that all residential parking stalls be Energized. As part
of the Terms of Reference for this study, the City requested commentary on the following question:
For parking stalls that are not “Energized”, should the City specify that remaining stalls feature a “Partial
EV Infrastructure” configuration? The proponent should propose a “Partial EV Infrastructure” definition that
can be included in City regulation. The proponent should then describe the benefits and drawbacks of
including this definition in City regulation, and recommend whether it be included.
Although “Partial EV infrastructure” configuration specifications were developed, it is not recommended
that the City make reference to this configuration in the requirements due to:
· Higher costs associated with completion of the installation at a later-date. Appendix B includes Partial
Infrastructure costing analysis;
· Additional time associated with completion of the installation at a later-date;
· Delays in gaining strata approval;
· Extending the sales cycle (awaiting installation of charging infrastructure);
· Common property complications associated with apportioning of costs;
· Reasonable costs associated with “Energized” infrastructure;
· Complications with parking stall re-assignment;

Page 4
AES Engineering Ltd. 1330 Granville Street, Vancouver, BC, Canada V6Z 1M7 P 604.569.6500 F 604.569.6501
· Disincentive of additional costs for the EV owner, which is contrary to the initiative to encourage EV
adoption (i.e. Demand elasticity is high (between 3.0 and 4.0), which means sales are significantly
impacted by price);
· Inclusion of Partial EV infrastructure assumes EV adoption will follow a linear progression as opposed
to exponential, which is contrary to the historical record for disruptive technologies.
Analysis identifies that Partial EV infrastructure provision represents significantly higher final costs
compared to complete (Energized) installations. Depending on building archetype and design, selected
infrastructure configuration, and extent of partial provisions, the increase in final costs (with the exception
of the townhouse archetype) ranges from 20% to well over 700%. Refer to Appendix B for a summary of
results of the Partial EV infrastructure costing analysis.
Given acceptance that EV adoption is required to meet GHG emission reduction targets, and widespread
projections for exponential growth in uptake of EV’s, the logical conclusion is that provision of Partial EV
infrastructure incurs additional time and cost on future buildings owners and residents, and is contrary to
the objective to better enable wide-spread adoption. On this basis, complete EV infrastructure installation
(Energized) should not be viewed from the perspective of an “additional cost” compared to Partial EV
infrastructure, but more appropriately, a “cost savings” compared to Partial EV infrastructure.
3.2 M INIMUM PERFORMANCE LEVELS
As part of the Terms of Reference for this study, the City requested commentary on the following question:
Should the City specify a minimum performance level for EV Infrastructure (e.g. a kW minimum; or
average and maximum kWh overnight delivered to stalls)? This could preclude load managed designs that
provide insufficient power to effectively charge vehicles. The proponent should recommend whether a
minimum performance level is necessary, and recommend a performance level if so.
The recommended minimum performance level is:
A minimum performance level of 12 kWh per EVSE, over an eight (8) hour overnight period. Load
management and/or load sharing may be implemented.
Refer to Appendix G for details of the basis for the minimum performance levels.
Analysis indicates that a 40A 208V connection to each parking stall, with circuit sharing of up to four
stalls per branch circuit, or equivalent (additional chargers on a circuit of greater ampacity) is sufficient to
provide the minimum charging requirement. This is based on provision of load sharing to maximize
utilization of circuit ampacity, and to benefit from the capacity pooling effect of sharing, in lieu of
restricting each charger to a maximum of 25% of the circuit ampacity.

Page 5
AES Engineering Ltd. 1330 Granville Street, Vancouver, BC, Canada V6Z 1M7 P 604.569.6500 F 604.569.6501
The above statements should not be interpreted to preclude the use of alternate configurations to achieve
the minimum performance level. It is highlighted that it is not the intent to limit the options of designers,
only to establish a minimum performance level to be achieved. A minimum performance level is
necessary to ensure an appropriate experience for the EV owner, thereby encouraging EV adoption.
It is understood that the City may wish to entertain reduced performance requirements, including Level 1
charging, in some specific instances where average driving distances of residents of a specific building are
considered atypical/limited. It is highlighted that the industry is generally coalescing around Level 2
charging due to the reasons of performance requirements (average driving distances) and consumer
expectation. Level 2 charging is considerably more consistent with the objective to better enable wide-
spread adoption, and represents a lower initial infrastructure (not including EVSE) installation cost than
Level 1 charging where load sharing is implemented. Should there be specific instances where the City
considers reducing the requirement to Level 1 it is recommended that some level of performance
augmentation, such as the installation of a number of dedicated Level 2 or DC fast chargers, be
considered. Metering issues inherent with Level 1 charging would also need to be carefully considered in
any such instances.
3.3 ACCOMMODATING “LOAD MANAGEMENT” AND “LOAD SHARING”
As part of the Terms of Reference for this study, the City requested commentary on the following question:
Should the City make any special requirements to ensure that EV infrastructure configurations designed
for “load management” will be able to be used by building occupants? E.g. Should an EV charging
infrastructure design be shown to be compatible with specific EV charging service providers’ offerings (or
multiple different service providers)? Should a contractual relationship with an EV charging service
provider be demonstrated? The proponent should recommend any requirements appropriate for the City to
pursue during its development approvals process.
The recommendation is to not preclude “load management/load sharing” configurations, as many are
capable of achieving the minimum performance level, and are cost effective installations. The process of
amendment to CSA C22.1 (refer to Appendix F for further details) to clarify the allowance of load
management, is in progress. Requirements should allow designs to be based on any system capable of
achieving the minimum performance level, and not favor a specific vendor. Contractual relationship with
an EV charging service provider whilst to be encouraged for reasons of quality of service, is not necessarily
recommended for inclusion in City regulation. Requirements proposed for inclusion during the
development approvals process are the definitions and minimum performance levels.
Load sharing solutions provide the opportunity to significantly reduce infrastructure costs by avoiding the
inherent high costs of dedicated circuits. A Level 2 load sharing installation is less than one-third the cost
Electric Vehicle Charging Requirements – AnalysisCity of Richmond
Page 6
AES Engineering Ltd. 1330 Granville Street, Vancouver, BC, Canada V6Z 1M7 P 604.569.6500 F 604.569.6501
of a dedicated circuit installation; and even less than a Level 1 dedicated circuit installation. Historically,
installations and Codes have been based on dedicated circuits. Analysis identifies there are significant
opportunities for cost reductions through the implementation of load management and load sharing
solutions.
The trade-off for the cost benefit is reduced performance and restriction on EVSE selection. A minimum
performance level requirement, as designated in Section 3.2 addresses the performance issue. In terms
of EVSE selection, the equipment must be capable of load sharing, which means a networked EVSE, as
opposed to standalone. At present EVSE equipment from various manufacturers is not open protocol and
cannot work in a sharing arrangement with equipment from other manufacturers. This means a
requirement (at present) to select one manufacturer, at least for each shared circuit, and more
realistically/appropriately for each building.
Additional benefits of networked systems include monitoring and maintenance features, thereby
improving the experience for the EV owner, which better enables wide-spread adoption. It is anticipated
that in the future all chargers will be “smart chargers” with increased features and range of available
services and capabilities, eventually including open protocols to allow greater selection and
interconnection of equipment. It is also anticipated that capabilities will further develop in relation to
instantaneous monitoring of available building electrical capacity to maximize charging performance
whilst minimizing infrastructure costs.
3.4 B ILLING SYSTEMS
To ensure electricity consumption costs are appropriately apportioned to EV owners it is recommended
that revenue grade metering (one meter) be provided on electrical distribution equipment feeding EVSE
equipment. “Apportioning of costs” as opposed to “resale of electricity” may then be performed via
metering integral to the EVSE equipment. Alternatively, as is the case in 20 US states currently, “resale of
electricity” by the strata organization may be performed based on metering integral to EVSE equipment,
once issues with the BC Utilities Commission Act (and other regulations) are resolved.
3.5 MECHANISMS TO ENSURE AVAILABILITY OF CHARGING
The recommendation to avoid “Partial EV infrastructure” minimizes potential restrictions to charging
availability and avoids complexities inherent with parking stall re-assignment. However, it does not
eliminate all possible impediments to an EV driver being able to charge. Provincial “Right-to-Charge”
legislation similar to that enacted by the State of California (on September 21, 2014) would ensure
availability of charging to MURB residents. Costs associated with the purchase and installation of EVSE
equipment, electricity consumption costs, and ongoing maintenance of the EVSE equipment would be

borne by the EV owner. Costs associated with “Energized” provisions would be borne by the developer of
the property. California’s Right-to-Charge legislation is included in Appendix H.
City of Richmond staff have noted their preference for effective provincial Right-to-Charge legislation to
ensure access to EV charging in buildings subject to EV infrastructure requirements. In the potential
absence of provincial action, City staff note that Right-to-Charge provisions may be included in strata
bylaws and/or covenant, which could be secured through rezoning and development approval processes.
Potential clauses for such mechanisms are included in Appendix H.
4.0 ASSESSMENT OF DIFFERENT EV INFRASTRUCTURE REQUIREMENTS
4.1 L IFE CYCLE COSTING
Analysis identifies the opportunities for significant cost savings through the implementation of load
managed and load shared solutions. While the life cycle cost for the 100% AC L1 “energized” (dedicated)
configuration represents the lowest cost over a 20-year period (due to the absence of the Level 2 charger
and EV service costs) it comes at the cost of performance. The 100% AC L2 “energized” (4-way load
shared and load managed) configuration represents the least expensive option assessed as achieving the
recommended minimum performance level. It also represents the least expensive initial cost of any
option (including the 100% AC L1 “energized” (dedicated) configuration), at an average of $561/stall for
the four archetypes.
EV service costs include all provider service charges, including incorporation into the provider system,
configuration of chargers, monitoring (operation, usage), control of access to chargers (users, time), 24/7
remote support, generation of reports, and software updates.
Refer to Appendix A for a complete summary of results of the costing analysis. Cost estimates were
primarily developed using RSMeans 2017, with additional review by Mott Electric GP.
4.2 QUALITATIVE COMMENTARY
In accordance with Section 3.2 a minimum performance level of 12 kWh (over an eight-hour period),
which corresponds to a 65km of charge range is considered a reasonable compromise between
performance and price, for a MURB installation in the City of Richmond.
The 100% AC L1 “energized” (dedicated) configuration provides the lowest charging rate at 1.4kW, and
the 100% AC L2 “energized” (dedicated) configuration provides the highest charging rate at 6.3kW. Refer
to Appendix G for details of charging rates for the various configurations.

5.0 CONCLUSIONS
5.1 RECOMMENDATIONS
The cost analysis identifies the 100% AC L2 “energized” (4-way load shared and load managed)
configuration as a reasonable compromise between price and performance. It also avoids concerns
inherent with “Partial EV infrastructure” installations. Whilst it has been identified as a reasonable
solution, it should not preclude other configurations or favor a specific vendor. It is recommended that
alternate configurations that can reasonably be verified to achieve the minimum recommended
performance level for a specific installation, be deemed acceptable.
Solutions that provide an improved performance level are particularly encouraged, to inspire range
confidence and maximize the experience for the EV owner, thereby further encouraging EV adoption. For
example, a minimal provision (1% - 2% of stalls) of DC Fast charging (in suitably accessible locations) for
larger developments (>100 stalls), whilst not included in the recommendations, is encouraged for
consideration during the development process, to increase EV adoption, sustainability, and marketability
of the development.
It is understood the City may have the ability to offset costs associated with EV infrastructure through
reduction in the required/designated number of parking stalls. Through implementation of load managed
and load shared solutions (as opposed to dedicated circuits) the reduction in parking stalls necessary to
offset costs would be minimal (2% – 3%). A reduction in parking stall numbers would also be consistent
with the trend towards reduced vehicle ownership, increased sharing options and membership, and
associated potential future impacts of autonomous vehicles.
The larger disruptive technology of battery storage (which EV’s are a component) can be expected to play
a role in influencing charging infrastructure and EVSE equipment in the future. Autonomous and wireless
technologies are also expected to impact requirements in the longer-term.
We understand that the recommendations are likely to inspire considerable comment and debate from
the many and varied stakeholders. For this reason, we recommend further consultation with the various
stakeholders, to ensure appropriate opportunity for expression of opinions and due consideration, prior to
implementation of any final requirements. With the increasingly rapid developments inherent with this
disruptive technology, the perception of the recommendations is also likely to change within a short
period of time, and the consultation period would provide such time.

Townhouse – Outside City Centre 36 2,340 433
TABLE F2: POWER OUT
Charging requirement (kWh/day) = Energy (kWh) consumed per day per EV x number of EV’s
Energy consumed per day (kWh) = Distance driven per day (km) x Energy Consumption rate (kWh/km)
Distance driven per day = 65km (allowance). The 65km allowance is considered appropriate, based on the
following:
• Average distance driven per day in Vancouver is 45km; (16,400km/yr).
• 95% of daily distances driven are less than 177km.
• Multiple consecutive days with daily driving distances in excess of the charging allowance will require
supplementation through the use of public DC fast charging.
Energy Consumption rate = 0.185kWh/km. The majority of vehicles being small or medium passenger
vehicles, with a battery size of 300kWh. Factors to be considered for descriptive (as opposed to prescriptive)
performance level recommendations also include:
• Variability of daily driving distances based on the distribution of daily driving distances for BC
environmental and geographic factors such as temperature, rain, snow, wind, and elevation, which have
a considerable impact on energy consumption.
• Demographics of the residents of the building and/or community including factors such as age,
workplace commuting patterns, and family situation.
• The majority of vehicles being small or medium passenger vehicles with an efficiency of 185 – 200
Wh/km, and a battery size of 300kWh.
• The majority of vehicles arriving at the residence between 4pm and 9pm and typically leaving no earlier
than 6am.

1.7 PERFORMANCE ANALYSIS
Maximum km for 4-shared (power transfer = power required)
Maximum Power Transfer (kWh/EV) = Volts (circuit) x Amps (circuit) x derating x efficiency / 1000 / number
EV’s on shared circuit
Maximum Power Out = Maximum Distance (km) x Energy Consumption rate (kWh/km)
Maximum Distance = Maximum Power Out / Energy Consumption rate (kWh/km)
Maximum Power Transfer (kWh/EV) = 208 x 40 x 0.8 x 0.95 x 8 /1000 / 4 = 12.65 kWh
Maximum Distance = 12.65 (kWh) / 0.185 (kWh/km) = 68.35 km
2.0 CONCLUSIONS
2.1 GENERAL
The Level 2 configurations, with sharing of up to 4 EVSE’s on a 40A, 208V circuit, or equivalent (additional
EVSE’s on a circuit of greater ampacity), achieve the minimum recommended performance level. This
should not be interpreted as precluding alternate configurations, provided they can reasonably be shown to
achieve the intent of the minimum performance level for a specific installation. The ability to review
proposed alternatives and enforce the minimum performance level requirements should be considered in
determination of the most appropriate solution for the City.

1.0 EXAMPLE BYLAW
1.1 POSSIBLE CLAUSES FOR CITY OF RICHMOND
(a) Provide Energized EV charging Infrastructure for all parking stalls, to meet a minimum performance
level of 12 kWh per EVSE, over an eight (8) hour overnight period.
(b) Load management and/or sharing may be implemented.
(c) Provide dedicated revenue-grade metering (one meter per building) on the main supply to EVSE
electrical distribution equipment.
Definitions:
Energized: All infrastructure required for charging of an electric vehicle (EV), including all electrical
equipment (including metering), cabling and associated raceways, and connections, with
exception of the Level 2 EVSE equipment;
EV: Electrical Vehicle;
EVSE: Electric Vehicle Supply Equipment (i.e. charger);
kWh: kilowatt hour;
Load Management: Control of the current drawn by the EVSE, at the main switchboard of the building;
Load sharing: Control of the current drawn by multiple EVSE on a single circuit, to ensure the capacity of
the circuit is not exceeded, and that maximum charging is achieved at each EVSE based on
the available capacity.
Explanatory notes:
A 40A 208V connection to each parking stall, with circuit sharing of up to four stalls per branch circuit, or
equivalent (additional chargers on a circuit of greater ampacity) is sufficient to provide the minimum
charging requirement. This is based on provision of load sharing to maximize utilization of circuit ampacity,
and to benefit from the capacity pooling effect of sharing, in lieu of restricting each charger to a maximum
of 25% of the circuit ampacity.
The above statements should not be interpreted to preclude the use of alternate configurations to achieve
the minimum performance level. It is highlighted that it is not the intent to limit the options of designers,
only to establish a minimum performance level to be achieved. Alternate configurations that can reasonably
be verified to achieve the minimum recommended performance level for a specific installation are
acceptable. Solutions that provide an improved performance level are particularly encouraged.
