6 FAQs about [Parallel battery charging and discharging]

Why should a battery be operated in parallel?

Operating batteries in parallel improves the battery power system management and resolves the problems of conventional battery banks that arrange batteries in series. This method allows the independent control of discharging currents from each battery, while coordinating them to provide a full amount of the load current.

What are the disadvantages of a parallel battery module?

Moreover, the battery directly connected to the battery posts ages faster than the other batteries, which has a negative impact on the lifetimes of battery packs. In addition, the self-equalization current among individual batteries in parallel battery module is large, which results in a waste of energy.

What is charging/discharging process?

In charging/discharging process, the battery cell directly connected to the battery posts is rapidly charged and discharged. The voltage of this individual battery reaches the cut-off condition quickly, while that of the parallel battery module does not and the charging/discharging process continues.

What is the difference between a parallel battery and an individual battery?
