THE CENTRAL QUESTION ... What issues do I need to understand to participate in the EV debate? What real, what's hype and where are the facts? COURSE ABSTRACT A discussion of many of the arguments used by those who suggest that EVs cannot be a legitimate challenge for ICE vehicles. Each anti-EV arguments is presented followed by interpretation, counter arguments, and facts.

Electric Vehicle University - 250b THE EV DEBATE
- 1. 1
- 2. 2 The EV Debate, part 2 EV-250b This course is presented as part of Evannex University—a free, open learning environment that presents concise, video-based mini-courses for those who have interest in electric vehicles (EVs) …
- 3. EVs vs. ICE Vehicles—The Debate
- 4. EVs vs. ICE Vehicles—The Debate
- 5. EVs are toys, poor performance… ROTFLMAO … 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 time Besides, the “roar” is soooo 20th century! 5
- 6. EVs are niche vehicles … That’s true! But so are sports cars, motorcycles, pickups, and minivans Everybody’s needs are different Just because EVs aren’t for everyone, doesn’t mean the potential market for them isn’t huge 6
- 7. Batteries degrade with time… Batteries do degrade, but so do internal combustion engines Most EVs have 7 or 8 year battery warrantees and no EV battery will “brick” unless it is grossly abused EV batteries degrade ‘gently’ by losing some of their capacity Corollary: It will be very expensive to replace a battery Today, yes, but prices will drop significantly
- 8. Batteries take too long to recharge … There’s some truth to this, but … 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, If you’re traveling, recharging time does matter 8
- 9. Using my heater or AC will reduce my range by 1/3 … Nonsense! EVs use every efficient heaters and AC units, so driving just a few mph slower compensates nicely typical battery capacity loss is 5 to 10% 9
- 10. There are safety issues, EVs catch fire… 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.

- >> There’s an ongoing debate about the future of the automobile.
- There’s an ongoing debate about the future of the automobile. Aligned on one side are proponents of the Internal Combustion Engine On the other side are proponents of EVs This is the second of a 3 part EVU mini-course on the debate. In this part, we’ll consider arguments that focus on the vehicle, batteries, and safety. In part 3, we’ll consider the debate about the grid, the environment, and the future.
- From those who are unaware of the wide array of EVs currently on the market, you sometimes get … EVs are toys, they’re 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 aren’t real cars or can’t 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 there’s 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!
- again, from those without much knowledge of EVs, you’ll sometimes you’ll hear the statement: “But EVs are niche vehicles …” >> That’s absolutely true! >> But so are sports cars, motorcycles, pickups, and minivans — to name just a few >> Everybody’s needs are different >> and just because EVs aren’t for everyone, doesn’t mean the potential market for them isn’t huge
- 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, it’s expected that a large Li Ion battery will loose approximately 20 percent of its capacity. Then there’s this corollary … >> It will be very expensive to replace a battery >> Today, that’s true, but battery prices will drop significantly before the first EV batteries begin to show significant signs of capacity loss.
- While we’re on the subject of batteries, you'll sometimes hear the argument… “Batteries take too long to recharge…” >> There’s 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 you’re 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 it’s proves out and is widely adopted, it could be a game changer.
- And finally, still another battery related objection, “Using my heater or AC will reduce my range by 1/3 …” >> That simply isn’t 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 you’re traveling to the edge of your battery’s range.
- When other anti-EV arguments crash and burn, anti-EV advocates sometime talk about crashing and burning, literally. You’ll 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
