The JK-B2A25S-RP battery management system (BMS) is intended for large-capacity (high current and many cells in series) lithium battery packs.
It can be configured to operate with other battery types such as ternary lithium, lithium Titanate (LTO) etc.
The system supports 3 to 25 cells connected in series.
The JK-B2A25S-RP performs the standard BMS functions i.e. protection against:
a) over/under cell temperature,
b) over charge or discharge currents
c) over/under cell voltages
In addition the JK-B2A25S-RP also performs an active cell balancing function.
Active balancing takes energy from the highest charged cell (cell with highest voltage) and transfers this via a super capacitor to the cell with the lowest voltage.
Being active no energy loss is experienced in the process (passive balancing uses resistors to balance but this creates a lot of energy loss).
Balancing happens as long as the BMS is connected to and powered by the cells.
