Hang on, there's some posts from someone who takes it to the track and did run into a temp limit. The solution was to stop using regen. I'll search for it. Give me a couple minutes.Okay, thank you. I was hoping for maybe some kind of number limit. I will be at a track event and plan to charge between sessions. It would be nice to know limits before i run into them.
Okay, here's the info:Does anybody know or is there any literature as to
what is considered too hot for battery coolant temperature and transmission temperature? I want to know before i have pushed the car too hard.
In aggressive driving and racing application the parameters that the Botl EV regenerative brake system was designed for changes significantly and a Big Brake Kit becomes relevant. With aggressive repeated braking as done on a race track, I have seen the electric motor on the bolt spike close to 300*. This is due to the regenerative brake system becoming overwhelmed trying to deal with both the rapid flow of incoming energy and then rapid application of energy for acceleration. In addition to better brake feel, my EV-MODS Big Brake Kit stores additional heat in the mechanical brake system vs sending it to the electric motor and battery (Bolt has had no issues with bat temp in racing just motor temp). A big brake kit does not reduce the efficiency of the regenerative braking system but it does give excessive heat a place to go. With a big brake kit on the Bolt EV the temperature of the electric motor runs about 50% to 100% cooler than without.
