Through the use of modeling, the BMS HIL Test System can measure the response of the BMS to unique cell chemistries, such as LiCoO2, LiNiO2, and LiFePO4.

The system simulates drive profiles, charge/discharge cycles, thermal runaway, and other faults for firmware development and optimization.

The BMS HIL System provides all of the simulated inputs to the

BMS, including communication from the embedded controller as well as cell

voltages and currents.

BMS Testing Throughout the Development Lifecycle

Battery management system (BMS) testing poses many challenges:

• Testing the BMS without the battery pack

• Testing the BMS under all the necessary conditions

• Safely testing at the extremes

• Testing embedded control algorithms in real time

• Modeling and simulation of batteries

Bloomy offers test solutions that address these challenges throughout the BMS development lifecycle.

Proof of Concept Small-scale hardware prototype testing

Hardware Prototype Full-scale hardware prototype with limited firmware.

The Battery Simulator 1200 is a commercial, off-the-shelf product used by industry leaders in automotive and grid storage. It is the fundamental building block of every Bloomy BMS test system. The BS-1200 is stackable up to 16 units in series equating to a 192 cell pack, sourcing up to 960V.

Firmware Development Iteratively develop, compile, and test firmware.

Validation and Verification Comprehensive testing of all specifications – performance and environmental

The BMS Validation System is a configurable platform to accommodate the variety of battery input signals such as cell counts, sensors, IO, and communications required for functional testing during BMS laboratory evaluation, highly accelerated stress screening (HASS), or highly accelerated life testing (HALT).

Validation testing is most often performed on a product sample size; therefore the BMS Validation System was designed to accommodate testing multiple units simultaneously, and also provides an interface to control environmental chambers to provide a complete test atmosphere.

The BMS Manufacturing Test System performs function-al testing of product during end-of-line manufacturing.

The system application easily integrates into manufac-turing processes, provides a method to test multiple product types, and optimizes tests to ensure that key production failures are captured and prevented from

release.

The same BMS Manufacturing Test System provided to CMs for production test is also used by OEMs for RMA Testing. Retest products returned from the field for firmware upgrades and recalibration. Run diagnostics to provide feedback to R&D for process and product improvements.

Production Test Manufacturing functional “end-of-line” testing

RMA Test Test, update firmware, and/or recalibrate any BMS returned from field service
