EVs vs. ICE VehiclesThe Debate

Theres an ongoing debate about the future of the automobile.

Aligned on one side are proponents of the Internal Combustion EngineOn the other side are proponents of EVs

This is the second of a 3 part EVU mini-course on the debate. In this part, well consider arguments that focus on the vehicle, batteries, and safety. In part 3, well consider the debate about the grid, the environment, and the future.

EVs are toys, poor performanceROTFLMAO take a test drive in a Tesla P85D!Corollary: Okay, maybe EVs can be fast, but I need to hear the roar of the ICE performance trumps background sound every timeBesides, the roar is soooo 20th century!

From those who are unaware of the wide array of EVs currently on the market, you sometimes get EVs are toys, theyre not real cars, they go 0 to 60 in, like 20 seconds

Obviously, small EVs like the Nissan leaf or the Chevy Spark are not designed or sold for performance.

But if you think EVs arent real cars or cant perform,>> take a test drive in a Tesla P85D! It is the fastest sedan in the world with overall handling, cornering and acceleration that rivals many high performance sports cars.

>> Then theres the Corollary: Okay, maybe EVs can be fast, but I need to hear the growl of the ICE.

Seriously? Actually yes. Many gear-heads continue make that statement.

>> In my view, performance trumps background noise every time. A Toyota Corolla without a muffler growls, but its performance is, well, not impressive.>> Besides, the growl of an ICE vehicle is soooo 20th century!

EVs are niche vehicles Thats true!But so are sports cars, motorcycles, pickups, and minivansEverybodys needs are differentJust because EVs arent for everyone, doesnt mean the potential market for them isnt huge

again, from those without much knowledge of EVs, youll sometimes youll hear the statement:But EVs are niche vehicles >> Thats absolutely true!>> But so are sports cars, motorcycles, pickups, and minivans to name just a few>> Everybodys needs are different>> and just because EVs arent for everyone, doesnt mean the potential market for them isnt huge

Batteries degrade with timeBatteries do degrade, but so do internal combustion enginesMost EVs have 7 or 8 year battery warrantees and no EV battery will brick unless it is grossly abusedEV batteries degrade gently by losing some of their capacityCorollary: It will be very expensive to replace a batteryToday, yes, but prices will drop significantly

There is concern about the longevity of batteries, with this argument often stated as Batteries degrade with time

>> It is true that batteries degrade slowly with time, but so do internal combustion engines>> Most EVs have 7 or 8 year battery warrantees, and no EV battery will brick that is, fail catastrophically unless it is grossly abused>> EV batteries degrade gently by losing small percentages of capacity year over year. Over 8 years, its expected that a large Li Ion battery will loose approximately 20 percent of its capacity.Then theres this corollary >> It will be very expensive to replace a battery>> Today, thats true, but battery prices will drop significantly before the first EV batteries begin to show significant signs of capacity loss.

Batteries take too long to recharge Theres some truth to this, but The vast majority of charging takes place at your house, in your garageat night, when electric rates are low and grid capacity is highwhile you sleep, If youre traveling, recharging time does matter

While were on the subject of batteries, you'll sometimes hear the argument

Batteries take too long to recharge

>> Theres some truth to this but the argument misses the larger point>> The vast majority of charging takes place at >> your house, in your garage>> at night, when electric rates are low and grid capacity is high>> while you sleep

so who cares how long it takes, as long as your car is full when you wake up every morning.

>>On the other hand, if youre traveling, recharging time does matter, but as the charging infrastructure grows and improves, the speed of recharging, which is already as high as 150 to 170 miles of range in 20 minutes, will also improve.

In addition, Tesla Motors has developed a battery replacement capability that allows it to swap an empty battery for a full battery less time than it takes to fill an empty fuel tank. If its proves out and is widely adopted, it could be a game changer.

Using my heater or AC will reduce my range by 1/3 Nonsense!EVs use every efficient heaters and AC units, sodriving just a few mph slower compensates nicelytypical battery capacity loss is 5 to 10%

And finally, still another battery related objection,Using my heater or AC will reduce my range by 1/3

>> That simply isnt true>> driving just a few miles per hour slower compensates for the energy used by an AC or heater>> and even if, like me, you choose not to drive any slower, the typical battery capacity loss will be the neighborhood of 5 to 10 percent, not important unless youre traveling to the edge of your batterys range.

There are safety issues, EVs catch fireThere are 150,000 vehicle fires in the US every year and about 350 deaths associated with car fires99.9 percent occur with ICE vehiclesThere has never been a death associated with an EV car fireA gas tank is a bomb that can and does explode on high speed impactAn EV battery will not explode.

When other anti-EV arguments crash and burn, anti-EV advocates sometime talk about crashing and burning, literally. Youll hear something like: There are safety issues, EV's can catch fire

Any car can catch fire after a serious impact, but EVs are actually remarkably safe.

>> There are 150,000 vehicle fires in the US every year and about 350 deaths associated with car fires>> 99.9 percent occur with ICE vehicles

>> There has never been a death associated with an EV car fire

>> A gas tank is a bomb that can and does explode on high speed impact

>> An EV battery will not explode, allowing the driver to exit a vehicle without harm
