- Pickering Interfaces, a provider of modular switching and signal simulation solutions for electronic test and validation, announces a new family of battery simulator modules for electric vehicle (EV) battery emulation in battery management system (BMS) test applications.
The 41-752A (PXI) and 43-752A (PXIe) modules allow for direct voltage and current readback, either through programming or using Pickering’s software control interface. Each cell simulator is specified to ±5 mV from 1 V to 7 V.
Designed for electric vehicle, automotive, aerospace, energy storage and electric aircraft applications, the new battery simulation modules occupy a single PXI slot. They can have two, four or six battery cell simulators per module isolated from ground and each other, making it easy to connect in series to simulate batteries in a stacked architecture.
The 750V isolation level allows the modules to be used to simulate low power battery cells that are commonly used for vehicle propulsion. Battery load emulation is available up to 100 mA.
Each cell provides independent power and sense connections, allowing the simulator to sense a load remotely 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 can also independently read the voltage at the load (via sense lines) and the output current for each cell. When supplied with I/V readout, the driver can automatically adjust the module’s output voltage via a feedback system for greater accuracy.
