Fixed Current And Fixed Period Fast Charging Method

The characteristic of this method is that the battery is charged with a pulse charging current with constant current amplitude and cycle, and a discharge pulse is depolarized between the two charging pulses to improve the charging acceptance capacity of the battery. During the charging process, the charging current and its pulse width are not affected by the charging state of the battery. Therefore, it is an open-loop pulse charging. This charging method is easy to make the battery full of capacity, but if the protective device to prevent overcharge is not added, it is easy to cause strong overcharge and affect the service life of the battery. In this charging method, although depolarization measures are added to the whole charging process, this fixed depolarization measure is difficult to meet the requirements of the whole charging process.
