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