The first activation method can try fast charging, in short, push the electric vehicle to the fast charging station for two hours. When the charge is finished. Use a multimeter to measure, if the voltage rises, then use the original charger to charge, so that in general, the battery can be activated.
The second activation method can be parallel repair method, as the name suggests is to find a group of new batteries with the same primary battery model, and the new battery and the old battery in parallel, and then through the new battery discharge, after several rounds of cycles, the old battery performance will slowly recover, and there is a certain probability that it can be reactivated.
The third activation method can be used to charge the small, that is, to charge the small power charger first, and then use the original charger to charge. Taking 72V electric vehicles as an example, a 60V charger can be used to charge for half an hour, and then the original 72V charger is used to charge, so there is a certain chance that the battery can be reactivated.
