Battery Management Solution for Electric Vehicles

In electric vehicles today, there are two key parameters, the state of health and the state of charge. Renesas' Battery Management Solution (BMS) device supports these parameters. This demonstration highlights Renesas' ISL78714 automotive-grade Li-ion battery manager IC and the RH850/P1M 32-bit automotive microcontroller (MCU). In addition to the ISL78714 battery manager IC and RH850 MCU, the demo board is supported by a host of other Renesas products including the RAA270005 power management IC (PMIC), RV1S2752Q photocoupler, and the uPD166031A/32/33/34 and RAJ2800024/34/44 integrated power devices (IPDs).
