5. Over-current, under voltage, and low-temperature protection.
6. Self-Heating Technology for Low Temperature.
Battery Management System which is shortly known as BMS is an electronics circuit which is used to control the safe operation of the battery. It protects the battery pack from being over-charged (cell voltages going too high) or over-discharged (cell voltages going too low) thereby extending the life of the battery pack. Melasta offer the designing service for customized BMS. These are the main features of customized BMS design.
