Overview
Description
The ISL78714XB-EVKIT1Z is an evaluation kit that facilitates testing of the ISL78714 Li-ion battery pack analog front-end ICs. The ISL78714 monitors cell voltage and temperature, and provides 14-bit digital values, cell balance control, and significant fault detection. The ISL78714 also contains daisy chain hardware to provide robust board-to-board communication.
The evaluation kit operates as a stand-alone monitor or, combined with additional boards, creates a daisy chained application. One board operating alone allows testing of up to 14-cell series-connected Li-ion battery packs, using a standard USB interface to a PC. Up to 30 boards cascade (with daisy chain communication from board-to-board) to test systems with up to 420 cells.
Features
- Supports both stand-alone and daisy chained configurations
- Daisy chain capacitively coupled (direct board-to-board or cable connected) or transformer coupled cable connected (capacitor or transformer selected by jumper)
- External cell balance operation
- Cell voltages monitored after balance resistor to meet safety fault detection goals
- GUI provided export option for generation of detailed register, voltage and/or SPI communications log files
- USB microcontroller dongle runs HID firmware for enumeration and communications with Windows platforms
- Evaluation kit includes a resistor divider power supply board for cell voltage generation
Applications
Applications
- Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle (PHEV) and Electric Vehicle (EV) battery packs
- Electric motorcycle battery packs
- Backup battery and energy storage systems requiring high accuracy management and monitoring
- Portable and semi-portable equipment

Videos & Training
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).
