Hello, we got our model S recently and just realized we can't put a good breaker is our home for 60A charging or even 30A since we are already at the limit. We have been charging at 15A I wonder if this has any negative effect on battery life, I grew up with the idea that slow charging Li batteries would reduce their lifespan. Assuming this is true, I trust Tesla engineers are clever and would have designed the car to charge only a subset of batteries instead of all at once in order to avoid this problem. So... Is slow charging Li batteries actually bad for the battery? And if so does Tesla actually handle this cleverly? Or are we "damaging" our car by slowly charging at home?
I'm curious where you heard that slow charging a Lithium Ion battery was bad for it. Sounds like someone was trying upsell you on the rapid charger at some point with false information maybe. It's always been widely accepted that slower charging is actually better for most rechargeable battery types than rapid charging. In Tesla's battery chemistry specifically the different is nominal over the lifespan of the car so I wouldn't worry about the topic if were you.
aye, its quite the opposite, fast is worst than slow. with that being said, at slow chargers waste alot more energy than fast chargers due to the car needing to run alot of components for the charge but the charge is only at 15A so it will take awhile for it to complete
Tesla told me I can charge past max if I switch to 110v, it is so slow it will go past my 225miles to 265.
i've heard of this, the charger forgets what the max limit is and will just keep charging. should be ok as long as you remove before it gets to 320 miles, after that the computer will get confused
Mines an antique, 265 was max in 2012. He said if I'm going on long trip unplug from 220v at 225, plug to 110v, it's so little the computer wont stop till it hits 265. He said zero out all trip miles all the time, eats up range. Turn off DRL. Turn AC up to 75 , not 68. The guy said my antique with new more efficient motor and battery should get better range now.
