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 J2 and CMU J2_1 connector 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_19 and J10_20 are ethernet interface, new firmware can be downloaded through this interface with OTA function
J7 is JTAG interface for program debug and download
