Positive and negative pulse type activation device repair control method for power storage battery

Abstract

The invention discloses a positive and negative pulse type activation device repair control method for a power storage battery. The method comprises the step of providing a processing unit and specifically comprises the steps of calculating the actual capacity and actual voltage of the storage battery before repair according to the type of the power battery, rated capacity of the storage and rated voltage set by a user, calculating the repair termination voltage and the repair time of the storage battery, calculating the repair current multiple of the storage battery, calculating the repair positive pulse width of the storage battery, calculating the repair negative pulse width of the storage battery, calculating the actual capacity and actual voltage of the storage battery, amending the repair current multiple of the storage battery, calculating the repair positive pulse width of the storage battery, amending the repair positive pulse width of the storage battery, and amending the repair negative pulse width of the storage battery. Crystals inside the storage battery are subjected to high-voltage and high-current repair through appropriate positive and negative pulses, so that the aims of increasing the capacity of the storage battery and prolonging the service life of the storage battery are achieved.

Description

technical field [0001] The invention relates to the field of storage battery maintenance, in particular to a positive and negative pulse type power battery activator repair control method, which belongs to the field of repair and utilization of waste batteries. Background technique [0002] The existing control method for battery repair and activation mainly includes the following steps: 1) Calculate the actual capacity and voltage of the battery; 2) Calculate the repair activation voltage and current; 3) Charge with a constant current first, and when the charging current begins to decrease, after a certain delay Time to switch to constant voltage charging. After constant voltage charging for a period of time, it will be a repair round. Check the battery capacity, if it cannot reach 90% of the rated capacity, start constant current discharge, discharge to the battery discharge termination voltage, stop discharging, and restart Start step 2 to repair and activate; this method...
