Addressing the increasing adoption of electric vehicles in industries such as automotive and aerospace, Pickering Interfaces released a family of PXI-based switch and simulation modules for testing a battery management system (BMS). The solution can be optimized to meet exactly what's needed for the application at hand, and is easily modifiable to handle evolving requirements.
The company's PXI-based switch and simulation modules offer many advantages in testing a BMS. They create a flexible test system that can be optimized and modified, with an industry-standard open architecture promoting system longevity while mitigating obsolescence. It also enables the seamless integration of multi-vendor instrumentation and communication modules into the system.
The PXI/PXIe multi-cell battery simulator/emulator range is well-suited for battery-stack emulation and BMS testing, allowing for direct voltage and current readback programmatically or via the soft panel control. Features include an isolation specification of 1000 V, enabling a BMS test system that can support hundreds of cells of battery simulation, all contained within a single 19-slot PXI or PXIe chassis. The battery simulator modules can also be combined with other vendors' PXI modules, such as a CAN bus interface, to create a fully flexible HIL test system.
