Renesas Electronics RTKA489204DK0000BU Battery Manager Evaluation Kit

Renesas Electronics RTKA489204DK0000BU Battery Manager Evaluation Kit facilitates testing of the RAA489204 Li-ion battery pack analog front-end ICs. The RAA489204 monitors cell voltage and temperature and provides 14-bit digital values, cell balance control, and significant fault detection. The RAA489204 also contains daisy chain hardware to provide robust board-to-board communication.

The Renesas Electronics RTKA489204DK0000BU operates as a stand-alone monitor or, combined with additional boards, creates a daisy-chained application. One board working alone allows testing 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 the 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
GUI provided an export option for a generation of detailed register, voltage, and/or SPI communications log files

Cell voltages monitored after balance resistor to meet safety fault detection goals.
USB microcontroller dongle runs HID firmware for enumeration and communications with Windows platforms
The evaluation kit includes a resistor divider power-supply board that is used for cell voltage generation

Specifications

Cell voltage -5V to +5V (Note: No cell voltage can go below pack ground or above 65V)
External inputs ExT1 to ExT4 = 0V to 2.5V (external temperature measurement thermistors on board)

V_BAT = 12V to 65V
Two GPIO ports to monitor temperature (default) or general-purpose input or output
