Starting 2025, many countries around the world will begin a ban on the purchase of gasoline powered vehicles. As the policy grows closer to date, the development of the electric vehicle (EV) accelerates leading to a major breakthrough in battery technology. The battery plays an important role in improving the efficiency and safety of electric vehicles, and so does the battery management system (BMS).

Best Tool for BMS Verification
The Chroma 87001 Battery Simulator is a powerful tool for verifying the battery management systems. It has voltage and current measurement and monitoring capabilities, providing 0~5V voltage regulation and 0~5A bidirectional current function per channel with simulation of voltage variation for 480 battery packs (2000V/4.2V) connected in series. The equipped output voltage control is convenient in testing upper and lower limits of battery operating range. It supports active and passive balancing circuit tests in 0~5A and 0~500mA two current ranges with measurement accuracy up to 0.02%F.S. For 0~5A range (power increase when paralleled), the accuracy is up to ±1mA with resolution up to 100uA that can meet the active balance design circuit test requirements. For 0~500mA range, the accuracy is ±100uA (0.02%F.S.) with resolution up to 10uA that can meet the passive balance design circuit test requirements. It is suitable for BMS circuit boards for measuring battery cell current consumption.
Significantly Reduce BMS Verification Costs
Certainly, the battery management system can also be used to verify the battery cell; however, it cannot maintain the same characteristics for repeated tests due to the influence of temperature, charging and discharging speeds, aging degree, and efficiency, etc. Moreover, setting up too many battery cells in the laboratory could raise safety concerns. In the past, the engineers connected several DC power supplies in series on their desk to test the cell supervision circuit (CSC) by manually adjusting the voltage and parameters, which took time and space, and the functions can be tested were limited. Using the Chroma 87001 Cell Simulator for testing became the better solution.
Easy-to-Integrate Devices with Complete Driver
The Chroma 87001 Batter Cell Simulator can be adapted to the battery management systems for electric vehicles, electric scooters, hand tools, and energy storage batteries. It has been applied to testbed for hardware in the loop (HIL) application by some system integrators. Chroma offers "easy-to-integrate device" and "complete driver" to give system integrators free of worries.
Chroma ATE transited its successful experience in the power electronics test industry to the battery test industry. After years of hard work and collaboration with major car manufacturers and battery pack factories, Chroma is capable of providing hardware devices and software tools to meet the test requirements through the know-how about the unit under test, reducing the trouble occurred during testing.
