Bloomy Delivers BMS HIL Tester to UK Leader in Vehicle Electrification

Thursday, May 10, 2018

The BMS HIL Test System provides Williams Advanced Engineering with the flexibility to support a large number of electric vehicle customers with varying battery management system requirements

WINDSOR, Conn – May 10, 2018 – Bloomy Controls, Inc. (Bloomy) has successfully completed commissioning of a battery management system (BMS) hardware-in-the-loop (HIL) test system at Williams Advanced Engineering’s facility in Grove, UK.

The BMS HIL Test System allows a BMS to be tested using commercial off-the-shelf hardware and real-time models developed using popular modeling software such as Simulink, MapleSim, LabVIEW and C/C++ which greatly reduces the amount of real-world testing that is required and is particularly useful for validating the functionality of BMS firmware.

At the core of the delivered system are Bloomy’s Battery Simulator 1200 instruments. Every instrument provides 12 independently controllable and isolated cell simulation channels, each capable of recreating the sink and source characteristics of a lithium-ion battery cell. With this capability, Bloomy provides a safe and efficient method for the Williams Advanced Engineering team to accurately simulate a broad range of battery cell and pack conditions. Built upon National Instrument PXI Instrumentation and VeriStand and TestStand software, The BMS HIL Test System now provides Williams Advanced Engineering with industry-leading test equipment to match their industry-leading products serving the automotive electrification market.

The BMS HIL Test System provides Williams Advanced Engineering with comprehensive capability to simulate the entirety of necessary input and output signals to their BMS, as well as real-time test software to execute the battery and drivetrain models necessary to confirm proper operation of their BMS under a broad range of operating conditions. At the core of Williams Advanced Engineering’s business is the support of a large number of low- to medium-volume customers, which calls for a HIL test platform that is robust, flexible, and easily maintainable and scalable to support the varying customer requirements they must meet. The flexibility and scalability of the Bloomy system in both hardware and software will ensure the success of both current and future Williams Advanced Engineering’s world-leading battery pack development programs.
