PXI/PXIe Battery Simulator Module 41/43-752A Series
Targeting EV, automotive, aerospace, energy storage and electric aircraft applications, the new battery simulator modules occupy a single PXI slot. These 6-channel battery simulators are capable of supplying up to 7 V and 300 mA per channel. The channels are fully isolated from ground and from each other, allowing series connection to simulate batteries in a stacked architecture. The 750 V 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 provides independent power and sense connections, allowing the simulator to sense a remote load and correct for wiring losses. The battery simulator is designed to respond to dynamic loads, minimizing the need for local decoupling capacitors at the load. The module also can independently read the voltage at the load (via sense lines) and current for each channel.
A control line on the user connector allows the user to shut down all battery simulator channels with one signal. Multiple control lines may be linked together to easily inhibit the output when using many series-connected modules. This also provides a means of automatic shutdown when connectors are removed.
These modules can be combined with our other PXI switch and simulation modules, including high voltage switching, fault insertion, thermocouple simulation, RTD simulation, as well as with other vendors' PXI modules, such as a CANbus interface, to create a fully flexible BMS test system.
