It is important to understand what impact heating the battery has and at what speeds that impact occurs at.
I have seen as much as a 30 KW(40 HP) difference between my car’s max output in Track Mode with a warm battery vs. Sport Mode with an optimized battery. However, that output difference is negligible up to about 40 mph. After 40 mph the difference is fairly constant up to about 120 mph.
Now with a cold battery and a low SOC I have seen a potential difference of almost 90 HP.
Please note that just driving the car around might get the battery to 30-35 C. Optimal performance doesn’t occur till about 53 C. You can’t reach optimal performance without preconditioning the car.
A lot of people have treated driving the car aggressively as the same thing as preconditioning. That isn’t remotely close to the same thing. Yes, it can heat the brakes and motors to high temps but I have never seen it come close to heating the battery to preconditioning temps.
The highest battery inlet temp I have seen is 59 C when fast charging with the CCS adapter.
