Overview
The US134-118VBTPKEV1Z board demonstrates a proof of concept (POC) solution for a 20-28 cell battery management system (BMS). The board supports a wide input range of 40V-120V and output of 40V-118V with 20A of continuous discharge current and can be increased to 60A with additional thermal management. The RS-485 interface provides the flexibility to monitor system parameters like battery voltage, fuel gauge, and load/charging current, and also accepts commands to control the system, monitor faults, and traceback errors during system shutdown. For additional board control and modification, the Renesas E2 emulator (sold separately) grants flexibility to configure parameters like over-current threshold, cell balancing control, cell OV/UV limits, external temperature limits, faults masks, reduced cells operation, and more.
Features
- Supports 40V to 118V battery packs (20-28 cells)
- Wide charger input range 40V to 120V
- 20A continuous discharge current (60A with thermal management)
- Easily adaptable to operate with different battery cell counts
- User input and diagnostics available via RS-485
