We get lot of questions regarding EVs & myths related to EVs, being put forward by Big oil, Big Auto, Journalists & Petrol Heads. We think it's time to clear them out. For once & all.(writing twitter replies for same questions multiple times sucks also).
1. What are EVs?(yes we have seen comments from people asking if this EV runs on petrol. *sad strange noises)
- EV is short term used for Electric Vehicles. They run completely on electricity. Hybrids, combination of internal combustion engines & batteries, are not EVs. Tho companies advertise & report them as Electrified Vehicle, but it's NOT Electric Vehicle.
EVs are powered by batteries. Mostly Lithium Ion in different combination, like NCA, LFP.
2. Do I need to replace EV batteries every couple of years? - HELL NO
- HELL NO. NOPE. NEVER. Unless & until you got real bad luck. Even then you won't have pay a dime, because companies now generally gives 8 yr battery warranty. Yup 8 yr is now kind of industry standard.
Let's get to some facts on lifetime of EV Batteries.
Current Tesla batteries last for about 300-500k miles. The kind of which rarely someone drives in India in lifetime of a car.
Actual Tesla owners report about a 5% drop in battery capacity by the 50,000 mile mark but after that, the rate of degradation drops considerably. On average, cars with 160,000 miles on them still have 90% of their battery capacity remaining. Projecting forward from the real world data available, a Tesla battery should still have 80% battery capacity after 500,000 miles of driving.
We guess even with Today's tech, you are good with EVs.
This myth of changing batteries every couple of years have risen due to our experience with Smartphones.
But EV batteries are different from that in phones. They got a good BMS, cooling systems. Much better chemistry and cell type.
So batteries can last up to 5-8L km even as of now. You won't be driving that much either.
But wait. Tesla Million Mile battery is coming soon. You read that right. Million mile.
There is this video on youtube Jeff Dahn(Tesla Battery Research) Talking lithium Battery Additives.
Cells retaining 97% capacity after 5300 full cycles are possible!
Things are possible if companies spend in R&D. So you better ignore the FUD being spread on battery life.
Now you may argue that this is Tesla specific. Wait, Hyundai & MG are also giving 8yr warranty. And am sure battery tech worldwide will keep improving. If Tesla can, others can too. Even if not, you surely should't be worried about battery till 8-10 yrs.
Lets see some examples
1. Tesla owner becomes first to push Model 3 to 100,000 miles, gets 303-308mile range(comes with 310)
2. Leaf(not the best car in terms of battery tech) after 6 years and 100k miles having 80% capacity left.
3. What about recycling of batteries? they will be dumped into landfills. - BS
It's straight up bullshit.
EV batteries are being recycled. Companies have start to end programs for EV batteries.
“We have current partner companies on every major continent where we have cars operating that we work with to do this today and, in addition, we’re developing internally more processes, we’re doing R&D on how we can improve this recycling process to get more of the active materials back.”
“And ultimately what we want is a closed loop at the Gigafactories that reuses recycled materials. This isn’t impossible and we see a pathway to do it.”
Tesla claims to be “developing a unique battery recycling system” at Gigafactory 1 in Nevada. Tesla wrote in the impact report: “At Gigafactory 1, Tesla is developing a unique battery recycling system that will process both battery manufacturing scrap and end-of-life batteries. Through this system, the recovery of critical minerals such as lithium and cobalt will be maximized along with the recovery of all metals used in the battery cell, such as copper, aluminum and steel. All of these materials will be recovered in forms optimized for new battery material production.”
Not only Tesla, CATL is also recycling batteries. And every battery/EV manufacturer will.
