Pickering launches new PXI multi-channel battery simulation module - simulates stack voltages up to 1000V

April 19, 2023, in Clacton-on-Sea, UK. Pickering Interfaces, a global provider of modular signal switching and simulation solutions for electronics test and verification, today released the latest version of the 41/43-752A series of battery simulation modules for BMS test applications. Ideal electric vehicle battery pack simulation module product. As the electric vehicle industry shifts from 400V to 800V architecture, 41/43-752A-1xx increases the voltage isolation to 1000V, which will meet the needs of more users.

Targeted at electric vehicles, electric aircraft and other types of automotive, aerospace and energy storage applications, the battery simulation module occupies only one PXI or PXIe slot . The 41-752A-1xx (PXI) and 43-752A-1xx (PXIe) are 2, 4 or 6-channel battery emulation modules that provide 7V/300mA per channel. Channels are completely isolated from each other and from ground . Allows simulating cells in a stacked structure by connecting them in series. The 1KV isolation barrier allows the module to be used as a low-power version of the battery pack used to replace the battery pack used for vehicle power.

Each channel of the module can absorb 300mA to simulate a battery in a charging state. Each channel has independent power supply and detection pins, so that the simulation card can automatically detect the load terminal voltage and compensate for circuit losses. The module is designed to respond to dynamic loads, minimizing the need for local decoupling capacitors at the load side. The module can also independently read the load voltage (via the sense wire) and current of each channel.

The Battery Simulation Series modules can also be combined with other Pickering PXI switching and simulation modules, including high voltage switching, fault injection, thermocouple simulation and RTD simulation cards, as well as other manufacturers' PXI modules, such as CANbus interfaces, to create a flexible BMS (battery management system) test system. The 41/43-752A can also be used as a 6-channel fully isolated power supply with independent detection wires for each channel.

Paul Bovingdon, Simulation Product Manager at Pickering, commented: “By 2025, most of the EV industry is expected to move from 400V to 800V architectures, which will significantly speed up EV charging and help address range anxiety, 41 The enhanced voltage isolation of the /43-752C-1xx is critical to support BMS testing of battery packs up to 1kV.”

Pickering provides extensive software support for all products, allowing users to design their applications using operating systems and programming languages ​​(C/C++, .NET, Python, LabVIEW/LabWindows, MATLAB, etc.) to integrate seamlessly with their systems . Users can choose from all Microsoft-supported Windows versions, mainstream Linux versions and other real-time hardware-in-the-loop (HIL) tools such as VeriStand, LabVIEW RT and QNX. All modules are backed by Pickering's three-year warranty policy.
