- Battery management unit (BMU)
- One RD-BESSK358BMU board
- One power supply (24 V DC, 3.75 A)
- One power cord
- One ETPL cable
- One RS-485 cable
- One Ethernet cable
- One controller area network (CAN) cable
- One interlock cable
- One contactors cable
- One secure element antenna
- One USB to RS-485 converter
- Cell monitoring unit (CMU)
- One RDBESS774A3EVB board
- Three supply cables

2.1 BMU Features
The BMU is the control part of the BESS. The BMU processes the data, decides, and commands the system.
The RD-BESSK358BMU is the BESS reference design BMU for 1500 V applications. This BMU kit includes a power supply and five cables to interface with other parts of the BESS.
To learn more about the RD-BESSK358BMU, visit the website associated with this reference design, or read its user manual.
2.2 CMU Features
The CMU is the cell-sensing part of the battery management system (BMS). The CMU precisely monitors cell voltages and environmental temperatures to ensure safe battery operation. The CMU also enables fast cell‑balancing.
The RDBESS774A3EVB is the BESS reference design CMU for ETPL-based architectures based on the MC33774A battery cell controller. This CMU kit includes four cables to interface with other parts of the BESS.
To learn more about the RDBESS774A3EVB, visit the website associated with this reference design, or read its user manual.
2.3 BJB Features
The BJB is the pack-level sensing part of the BESS. The BJB measures high voltages. This measurement allows monitoring the connections of the contactors to the inverter and the charger. The BJB also precisely measures the system current and monitors the battery to chassis isolation.
The RDBESS772BJBEVB is the 1500 V BESS reference design BJB for ETPL-based architectures. This BJB kit includes 11 cables to interface with other parts of the BESS.
To learn more about the RDBESS772BJBEVB, visit the website associated with this reference design, or read its user manual.
