Pulse charge discharge depolarization fast charging method with constant current and constant gas di
The characteristic of this charging method is that the amplitude of charging current pulse and the air outlet rate of battery remain unchanged throughout the charging process.
At the beginning of the charging process, the charging current is slightly lower than the initial receiving current of the battery. During the charging process, the acceptable current of the battery decreases gradually, so after a period of time, the charging current will exceed the acceptable current of the battery, so more gas will be generated in the battery and the air outlet rate will increase significantly.
At this time, the gas detection element can send a control signal in time to force the battery to stop charging and discharge for a short time. In this way, the polarization inside the battery will disappear soon, so the air outlet rate can always be kept within a low predetermined value.
Many countries have such programs. However, some countries have little research on this method because of the lack of gas sensing elements.
