There was a problem of the following nature:
While driving, the engine began to randomly turn off. To continue using it, it had to be turned on again. I thought that the problem was in the battery and some cell in it was not working well. I left the battery to charge overnight so that the voltage levels on the cells equalized. The battery was charged by morning, but another problem arose, the engine stopped turning on altogether. Measuring the voltage at the battery output showed its absence. I took the battery apart and replaced the BMS board. After this, voltage appeared but the engine did not turn on. It turned out that the controller failed without any visible damage. I installed a new controller and the engine turned on. I drove for 5 minutes and when going uphill it turned off. As it turns out, the new controller has failed again, but there is still voltage from the battery. Now I can’t understand why the controller fails under load, can anyone tell me? This is of course stupid, but could this situation be caused by the engine control display on the steering wheel?
