Jaguar Land Rover, the UK’s largest automotive manufacturer, and Bloomy, a NI Platinum Alliance Partner, develop a system that provides the ability to design and validate battery management system (BMS) firmware algorithms on prototype hardware, and safely test the unit with various battery chemistries, fault scenarios, and drive profiles. Bloomy developed a hardware-in-the-loop (HIL) test system based on NI PXI hardware, VeriStand software and Bloomy's Battery Simulator 1200 instruments to simulate a 24-cell advanced chemistry, hybrid- and electric-vehicle battery.

Hardware-In-the-Loop (HIL) testing is the standard approach to validating the design of xEV ECU systems including the battery management system (BMS) electronics and firmware. HIL test systems are used to simulate the battery including cell chemistry, charging and discharging, drive cycles, and numerous fault conditions for testing the BMS; without the hazards of real batteries, or the cost of prototype vehicles and track time.

The key to accelerating development of electrified vehicle (xEV) batteries is to decouple the interdependencies which exist between development of battery management electronics and firmware, and the development of cells and packs. Advanced modeling, simulation, and test techniques can be used to develop the electronics and firmware concurrently with the cells and packs, thereby expediting xEV battery development cycles.

Simulate and measure BMS activity
The BMS Environmental Test System is a configurable platform simulating the essential signals used by Battery Management Systems (BMS) and cell monitoring modules with the ability to perform environmental testing on multiple BMS units simultaneously. The system implements single point value testing to evaluate specific BMS functions such as cell over and under voltage scenarios, cell leakage current, lost communications, or faulty system I/O.

Challenge
Bloomy and RDVS were tasked with developing a system providing the ability to rapidly produce Battery Management System (BMS) algorithms on physical hardware, and safely test the unit against different battery chemistries, fault scenarios, and drive profiles.
