Does Tesla have heaters on the battery packs?
- bguebert 3y agoyes
- brianwawok 3y agoYes
- roflyear 3y agoIt takes a lot of power to heat the batteries. If there is no power, can't heat them, and you can have total failure if you try and charge them when they are too cold.
- bryanlarsen 3y agoYou don't get total failure, you get an extended charging session as the car first warms the battery and then charges the car.
- Ferret7446 3y agoThe car needs enough power to warm the battery though. So what happens if the car doesn't have enough power and tries to warm the battery and runs out of power before it has warmed enough to charge?

- bryanlarsen 3y agoWhy would you need to use car power to warm the battery? If you're connected to a charger you can use charger power to warm the battery. And you can't charge if you're not connected to a charger, so charging a cold battery is impossible in that case.
- throwitaway222 3y agoThere should be a lot of power available if you're at a charger.
- Rebelgecko 3y agoMy understanding is that this particular Supercharger station is broken and either not putting out any electricity, or putting out way less than it should
- dghughes 3y agoI think battery heaters are standard and necessary on any EV battery.
- mensetmanusman 3y agonot all electric vehicles have battery heaters. Eg it's only part of the Eco pack for an Ioniq.
- Someone 3y agoThe issue at hand may be whether they keep the heaters on during charging. FTA: "A charge that should take 45 minutes is taking two hours."
- akmarinov 3y agoThey do keep the heaters during charing, unlike other manufacturers like Renault
