Use Dr.EV’s Charge Completion Time to finish AC charging near your morning departure and help your Tesla’s battery stay warmer in winter.

How Tesla battery temperatures vary with charging speed, how LFP and NCM/NCA compare, and why a battery can get warm even during slower charging.

Tesla can use the motor to warm the battery itself. In this case, about 4% of the battery was used just to raise battery temperature. Tesla does this to protect the battery. So if you ever notice a small battery drop without driving, it’s not a problem. It’s simply the car taking care of its battery.

When comparing Tesla charging data, an interesting pattern appears. Under similar charging currents, NCM batteries heat up more, while LFP batteries stay noticeably cooler. At first glance, this looks counter-intuitive. LFP chemistry is well known for being more thermally robust.

When you think about it, most electric vehicles spend far more time parked than being driven or charged. It may sound surprising, but a...
