MCV battery management systems provide a safe operating environment by monitoring cell voltage, current temperature of each cell, module or assembly, state of charge (SOC), isolation, and determine whether battery operating conditions are suitable to avoid malfunction. If a malfunction occurs, the BMS sends a fault signal to cut off battery operations and halt the flow of energy.

There are eight main functions involved in the MCV BMS. They are:


1. DC voltage is tested to measure the total voltage in each cell, as well as the complete module or assembly precisely and in real time. This effectively prevents malfunction due to faulty voltage characteristics;
2. Samples Temperature, and checks the temperature of each cell, module or assembly and when over temperature, immediately turns on a cooling fan to keep battery operation within optimum operating temperature range;
3. Current measurements, including actual current and over-current alarm protection;
4. Isolation following UL1642 standards;
5. State of charge estimation, both real time calculations of battery module SOC and instant discharge currents;
6. CAN-BUS high speed communication;
7. Discharge balancing. MCV BMS manages discharge imbalances to maintain uniform discharge function;
8. System self-inspection assures normal system operation of the BMS itself.
