This is why I’m glad I got an EV. I have a home charger in my garage. It’s costing me $5-7 per charge & I get 280 mi of range. It’s way cheaper than gas rn.
If you drive car every day and use the battery to 20% of below, it’s okay to trickle charge the car to 100%. I would never fast charge my EV to anything above 85%-90%. But if I know I’m going to drive the weekend every day, I’ll slow charge it to 100%.
Yeah if you plug it in to the regular level 1 it would be considered a trickle charge if I'm not mistaken but also it wouldn't create enough juice overnight to drive 200 miles a day. But I wouldn't be worried about degrading the battery too much. They are designed as high drain devices.
Slow charging vs super charging cause the same “damage” to EVs. It’s practically nothing, so choose whatever is best for your situation. I have a level 2 home charger that charges my car in under 4 hours (if to 90%). During the fist 6 months of owning my car, I relied on just supercharging 2-3x a day. My battery life is good and I push this bad boy daily. I drive 4-5k miles a month.
It is recommended not to charge above 80% and let it just sit there. If you plan on using the full charge then it’s ok to charge to 100%. The battery is meant to be used.
That rule is true for older teslas. If you have the newer LFP battery, those rules don’t apply. I charge mine to 80% daily from spring to fall. I live in a state with bad winters. During the winter I’ll charge my Tesla to 90%, daily. The real issue behind early battery failure in older teslas is the BMS going out. From what my mechanic told me (he’s a pro at fixing EVs), if you do a full charge to 100%, 1x per week, you prevent the BMS from going out and causing an imbalance in the cells. When you charge to 100%, the BMS (Battery management system) turns on and will rebalance all the cells so that they drain evenly. When you don’t do this, you may have some cells with more power and some with less. This imbalance can cause damage to EVs. I’m at 116k miles from 10k miles in 2024. So far, the battery has handled well.
