Basics on Cell Emulators
The Battery Management System (BMS) monitors and controls the operation of batteries in electric vehicles, aircraft and energy storage systems. Testing the BMS is essential to ensure that these batteries operate safely and reliably. This is where cell emulators come into play, accurately simulating the behavior of real batteries.
Test systems can be used to emulate battery packs at actual voltage and current levels. They enable automated, on-demand testing under reproducible conditions. Algorithms for estimating battery state of charge (SOC) and state of health (SOH) can be verified. Testing with emulated batteries is safer and faster than with real batteries because extreme conditions such as overvoltage or high temperatures can be safely simulated.
In addition, the Battery Cell Emulator (BCE) provides multiple independently isolated cells that can be connected in series to achieve high system voltages. This provides a comprehensive and safe test environment for the BMS.
Applications of Cell Emulators
The PTS Cell Emulator is our solution to provide cell sensing test capabilities for battery electronics in various systems including EVs or grid storage. With 18 differential cell voltage outputs the PTS Cell Emulator can be used in multiple applications during the whole development process. This brings significant gains for quality and speed in Software Development, Validation or End-Of-Line testing.
