1. Out of the Box
The S32K376 BMS evaluation board integrates the BMS and vehicle control unit (VCU) function. Analog front end (AFE) MC33774 is used to monitor battery status. Gateway MC33665 is used to transfer SPI signal to transport protocol link 3 (TPL3) and system basis chip (SBC) FS2633 supply power for S32K376 and external devices. High-Side Driver (HSD), Low-Side Driver (LSD) and Multiple Switch Detection Interface (MSDI) are used for VCU function. CAN, LIN and UART are used to communicate with other ECU. Real-Time Clock (RTC) is used to read real time for BMS State of Charge (SoC) calculation. You can watch the video to get the detailed function of each partition.

3.1 Using the S32K396BMS-EVB with a RD33774CNT3EVB (or X-KIT33774CTREVB) Board
Figure 1 shows the required hardware for operation of the S32K396BMS-EVB and RD33774CNT3EVB are shown in the following items:
- 1x S32K396BMS-EVB board with 3x cluster cable
- 1x RD33774CNT3EVB (or X-KIT33774CTREVB) board
- 1x BATT-18EMULATOR (or X-BATTDEV-CON24)
- 3x cell terminal cable
- 4x TPL3 cable
- PCAN-USB Pro
The basic power supply and signal connection are listed in the following bullet:
- The S32K396BMS-EVB board can be powered by connecting an external 12VDC power supply, the power connector (
J11_6,J11_14) is interface for power supply on the board - The RD33774CNT3EVB board can be powered by the evaluation battery board VBAT and GND. For further details, refer to the CMU board schematic
- Connecting S32K396BMS-EVB
J2and CMUJ2_1connector with TPL3 cable to setup the BMS communication channel - When connecting the PC and BMU connector (
J10_1,J10_2) with PCAN-USE Pro adapter, the GUI can get battery info from the BMU J10_19andJ10_20are ethernet interface, new firmware can be downloaded through this interface with OTA functionJ7is JTAG interface for program debug and download
RD33774CNT3EVB board has the same functions as X-KIT33774CTREVB board. Customers can apply for RD33774CNT3EVB as an alternative companion board.
