PXI multi-channel battery simulator modules emulate stacks up to 1000V
Six-channel PXI / PXIe 300mA battery simulators by Pickering Interfaces now have greater voltage isolation to allow battery management system (BMS) testing with battery stacks up to 1kV.
The latest version in Pickering Interface’s 41-752A-111 (PXI) and 43-752A-111 (PXIe) battery simulator modules are suitable for electric vehicle (EV) battery stack emulation in BMS test applications. It has voltage isolation of 1000V, which will be essential as the EV industry shifts from 400V to 800V architectures, said the company.
Targeting EVs, electric aircraft and other automotive, aerospace and energy storage applications, the battery simulator modules occupy a single PXI or PXIe slot. The 41-752A-111 and 43-752A-111 are two, four or six-channel battery simulators capable of supplying up to 7.0V and 300mA per channel. The channels are fully isolated from ground and from each other, allowing series connection to simulate batteries in a stacked architecture. The 1kV isolation barrier allows the module to be used as a lower power version of a battery stack, representative of those used for vehicle propulsion.
Each channel on the modules can sink up to 300mA to simulate a battery under charge and provide independent power and sense connections, for the simulator to sense a remote load and correct for wiring losses. The battery simulator is designed to respond to dynamic loads and minimises the need for local decoupling capacitors at the load. The module also can independently read the voltage at the load and current for each channel, either programmatically or via a manual soft front panel.
Modules can be combined with other Pickering PXI switch and simulation modules, including high voltage switching, fault insertion, thermocouple simulation, and RTD simulation, as well as with other vendors’ PXI modules, such as a CANbus interface.
The 41-752A-111 and 43-752A-111 can also be used as a six-channel fully isolated power supply with independent sense lines on each channel.
Pickering provides extensive software support for its products, allowing users to design their applications with the operating system and programming languages (C/C++, .NET, Python, LabVIEW/LabWindows, MATLAB) of their choice. Users can choose between all Microsoft-supported Windows versions, popular varieties of Linux, and other real-time hardware-in-the-loop (HIL) tools such as VeriStand, LabVIEW RT and QNX.
All modules are covered by Pickering’s standard three-year warranty.
