Advantages

Typical Cases

New energy vehicles are booming, with power batteries replacing fuel. The battery management system (BMS) is crucial, handling battery monitoring, diagnosis, and charge/discharge control. Poor BMS software reliability can cripple the battery pack, degrade vehicle performance, and pose safety risks. HiL testing, a key "V" process step, boosts software reliability post-development. It offers thorough, safe, efficient, and cost-effective validation—vital for OEMs and suppliers.

- Simulate all BMS hardwired inputs (AI, DI, PWM IN, resistors). - Collect its hardwired outputs (DO, AO, PWM OUT). - Generate signals for cell voltage, temp sensor resistance, high voltage, insulation, current sensors. - Enable bus & daisy chain comms simulation. - Inject cell faults: open/short sampling lines, out-of-range values, polarity reversal. - Test BMS functions like collection, relay control, SOC, thermal mgmt, charging. - Verify fault diagnosis. - Run NEDC and custom driving cycles.

The BMS HiL test bench provides these key functions:
