To charge series batteries, it is essential to follow a specific set of steps. Firstly, ensure that the charger voltage matches the total voltage of the series batteries. Secondly, connect the charger to the series battery pack, ensuring the polarity is correct.
No, it is not recommended to use a regular charger to charge series batteries. Regular chargers are designed for single batteries and may not have the appropriate voltage rating to charge a series battery pack. Using a regular charger could result in overcharging or damaging the batteries.
We further establish a connection between the battery pack and its series cells to enable pack capacity estimation. The proposed method is verified based on two sets of battery pack tests comprising 60 cells in series and with severe capacity inconsistency.
The equalization voltage threshold set was 10 mV. After active equalization, the maximum voltage difference between the battery pack cells was reduced to 9 mV, a relative decrease of 96.2%, which met the requirements of the equalization study.
According to the principle that cells are connected in series, the capacity remains constant, combining eqs 2, 3, and 15 can give the series-connected battery pack’s capacity utilization. t1 the is single Cell 1’s usage time from discharge to cutoff voltage, and t2 is single Cell 2’s using time from discharge to cutoff voltage.
