BMS HIL Test System Helps Jaguar Land Rover Shorten Time-to-Market for Hybrid and Electric Vehicles

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. The BMS HIL Test System delivers a flexible test platform that facilitates rapid design and testing of the BMS software, thereby accelerating development of JLR's prototype hybrid and fully-electric vehicles. JLR used the system in the R&D phases to validate four different BMS hardware architectures, including both centralized and master-slave topologies. After transitioning to production, all major BMS software revisions are comprehensively tested by the system prior to release.
