Melasta offers complete integrated solution for the battery include cell selection, BMS selection, integrated software solution and communication protocol integration with the required application. Melasta’s in-house research and development team is focused on designing the BMS according to customer requirements. These are the main features of our designed BMS
1. Support RS485, CAN BUS, URAT, i2c and other communication protocol
2. Up to 100a continuous discharge current
3. Support MOS high temperature protection function
4. Over voltage, over current, over temperature control function.
5. Over-current, under voltage, and low-temperature protection.
6. Self-Heating Technology for Low Temperature.
