Automotive Battery Management Solutions (BMS)

Hybrid Electric, Plug-in Hybrid Electric and Electric Vehicle (HEV/PHEV/EV) BMS

Intersil's ISL78600 and ISL78610 automotive grade Li-Ion battery management and safety monitoring chipset solution is specifically designed to meet the stringent safety, reliability and performance requirements of next generation Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle (PHEV) and Electric Vehicle (EV) applications.

Automotive Battery Management Solutions (BMS)

The automotive grade (AEC-Q100), ISL78600 12-cell battery pack manager can be used as a standalone part in ASIL compliant systems, deployed in conjunction with the complimentary ISL78610 for higher ASIL ratings or in systems requiring an independent backup solution. The devices provide built-in fault detection for all of their major internal functions and detect external faults such as open wire, over and under voltage as well as temperature and cell balancing faults to mitigate battery pack failures. Overall, the highly integrated functionality of the ISL78600 and ISL78610 offers a number of benefits and can significantly reduce the overall battery management costs of HEV/PHEV/EV battery packs and their associated systems.
