Getting Started with the RD9Z1-638BJBEVM

2.1 Board Description

The RD9Z1-638BJBEVM provides a platform for evaluating designs that implement NXP’s MM9Z1_638 Battery Monitoring System device. It connects to a power distribution unit (PDU) and enables voltage sensing, current sensing, temperature sensing and diagnostics of the contactor status.

The kit supports evaluations in conjunction with a CAN network and is ideal for prototyping High-Voltage Battery Junction Box (HV-BJB) systems.

2.2 Board Features

• Power supply input from 5 VDC to 12 VDC
• Up to seven voltage sensing channels for high-voltage measurements
• One current sensing channel to measure charge current and discharge current
• One temperature sensing channel to measure shunt resistor temperature for calibration
• Integrated insulation resistance measurement
• One channel isolated CAN communication to BMU/VCU

Figure 1.Configure the hardware

To configure the hardware, complete the following procedure:

1. Connect the negative pole of the HV Battery Junction Box to one side of the evaluation board's metal shunt
2. Connect the positive pole of the HV Battery Junction Box to the other side of the evaluation board's metal shunt
3. Open high-voltage connector 1 (J8) on the RD9Z1-638BJBEVM evaluation board and attach the 5-pin connector cable as follows:
   • Connect J8_1 to the HV ground
   • Connect J8_5 to the sensing position E
4. Open high-voltage connector 2 (J6) on the RD9Z1-638BJBEVM evaluation board and attach the 7-pin connector cable as follows:
   • Connect J6_1 to high voltage sensing position F
   • Connect J6_4 to high voltage sensing position G
   • Connect J6_7 to high voltage sensing position H
5. Open high-voltage connector 3 (JP1) on the RD9Z1-638BJBEVM evaluation board and attach the 10-pin connector cable as follows:
   • Connect JP1_1 to high voltage sensing position A
   • Connect JP1_4 to high voltage sensing position B
   • Connect JP1_7 to high voltage sensing position C
   • Connect JP1_7 to high voltage sensing position D
6. Open low-voltage connector (J7) on the RD9Z1-638BJBEVM evaluation board and attach the 4-pin connector cable as follows:
   • The first two terminals of the 4-pin cable are reserved for connecting to a CAN network
   • Using the third terminal on the cable, connect J7_3 to the low-voltage power supply
   • Using fourth terminal on the cable, connect J7_4 to the low-voltage ground
7. Open the probe cover and attach PEmicro's six-pin ribbon cable to the probe’s six-pin header (Port C)
8. Plug the other end of the 6-pin cable into the RD9Z1-638BJBEVM evaluation board’s BDM connector (J1)
9. Plug the PEmicro's USB cable into the PEmicro Universal Debug Probe’s USB port and connect the other end of the cable to a USB port on the PC workstation

3.1 Additional Board Support

Refer to UM11396, RD9Z1-638BJBEVM reference design user manual for additional details on the hardware configuration.

After configuring the hardware, users have to install and configure the CodeWarrior Integrated Development Environment (IDE) software required to run the demonstration examples and to exercise the RD9Z1-638BJBEVM in an evaluation environment.

4.1 Install CodeWarrior

1. Go to NXP and navigate to the CodeWarrior Development Tools site
2. In the Downloads section, select and download the latest version of CodeWarrior for MCUs
