Our 2nd-use batteries are supplied with BMS (battery management system). The BMS that we work with is used worldwide in large energy storage systems and electric vehicles.
This BMS monitors all cells for voltage, temperature, charging current. On the basis of this information, cells are balanced and the SoC and SoH determined. Without balancing, army cells remain the weak link in the system and thus limit capacity. In addition, the weaker cells are then loaded more, which can cause them to become thermally overloaded. By using a stable BMS, the safety and durability of the 2nd-use batteries are secured.
