High-Current, Scalable BMS Testing for Demanding Applications
The 5A Battery Simulator (41/43-754) is a PXI/PXIe module engineered for advanced Battery Management System (BMS) testing. With up to four fully isolated channels per slot, each delivering up to 8V and 5A, this simulator accurately emulates battery cells or modules in low- and high-voltage stacks. It combines high current drive, precision readback, and hardware safety features in a compact, modular platform.
Address Complex BMS Test Challenges
Testing modern battery systems is challenging, from ensuring safety during faults to managing scalable test hardware costs. Physical batteries are hazardous and unpredictable, while many simulators lack the scalability for pack-level validation.
Our 5000mA Battery Simulator offers a safe, repeatable, and cost-effective solution for BMS test. Simulate various operating conditions and faults without thermal runaway risks, speeding up development and cutting ownership costs.
Technical Capabilities
- High-Current Capability: Each channel delivers up to 5A, a significant step-up from traditional 300mA simulators. This allows for the parallel simulation of multiple cells, reducing the channel count required for high-voltage pack testing.
- Modular and Scalable Design: Built on the PXI standard, the system is inherently scalable. As your requirements evolve, add more modules to simulate higher-voltage stacks. This building-block approach protects your hardware investment.
- Robust Isolation: With 1000V channel-to-ground and 750V channel-to-channel isolation, you can safely connect modules in series to simulate the high-voltage battery packs used in EV propulsion systems.
- Precision Readback: Integrated voltage and current readback provides accurate measurements with 1mV and 1mA resolution for detailed performance analysis.
- Charging Emulation: The module can sink up to 7W of continuous power per channel, enabling you to test a BMS's response to various charging profiles.
Applications Across Industries
- Automotive: Validate Battery Management System hardware and software for EV and hybrid vehicle battery packs. Integrate with Fault Insertion Units (FIUs) for comprehensive failure mode testing.
- Aerospace & Defense: Perform rigorous testing on safety-critical systems, including battery stacks for electric aircraft, UAVs, and military-grade vehicles.
- Energy & Utilities: Simulate residential and grid-scale energy storage systems (ESS) to test inverter response, grid stability services, and load-shifting performance.
- Hardware-in-the-Loop (HIL) Testing: Integrate the simulator into your HIL system for real-time testing of BMS algorithms and state-of-charge estimation.
