Hybrid Electric, Plug-in Hybrid Electric and Electric Vehicle (HEV/PHEV/EV) Battery Management Solutions

Intersil's ISL78600 and ISL78601 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.

The automotive grade (AEC-Q100), ISL78600 12-cell battery pack manager can be used as a standalone part or deployed in conjunction with the complementary ISL78601 12-cell Li-Ion battery pack monitor to implement an ISO26262 (ASIL) compliant system. The solution provides built-in fault detection for all of its major internal functions and detects 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 ISL78601 offers a number of benefits and can significantly reduce the overall battery management costs of HEV/PHEV/EV battery packs and their associated systems.
