BCE Starter Kit

Predefined desktop setup for fast and scalable BMS testing

The (BCE) Starter Kit provides an easy entry point into battery management system (BMS) testing with a compact, ready-to-use desktop configuration. The kit includes a battery cell emulator (BCE) including a terminal board, a 48V power supply, and all required cables, enabling fast setup and immediate testing without requiring a full-scale rack BMS test system. The BCE Starter Kit is ideal for early BMS prototyping or validation tasks, allowing teams to start testing early and reduce time-to-market.

Designed as a scalable starting point, the BCE Starter Kit supports starting with a small testbench setup that can be expanded into a full-scale rack-based configuration system as the requirements grow. The kit configuration is as seamlessly integrated into Simulink^® and model-based design workflows as other configurations.

For full-scale BMS testing with the BCE, we recommend rack-based configurations.
