As the key component of electric vehicles, its lithium-ion battery (LIB) is tight up to personal safety and must pass car manufacturer’s most stringent performance tests to keep risks at a minimum. These diverse tests are complex and time-consuming. It requires specialized test equipment that can test multiple channels simultaneously as to reduce the time for the complete product verification. The Chroma 17011 regenerative AC/DC bi-directional battery test system passed the severe performance tests of major Japanese battery manufacturers. The test device performed excellent on items like current response, measurement accuracy, output dynamic waveforms, stability, and controlled feedback speed.

Constant power (CP) is the most common testing mode for LIB. However, the CP output is affected by electric potential differences in the battery’s internal resistance and easily generates overshoot. Creating fast output response without overshoot remains a complex issue for battery test equipment. LIB testing requires long-term simulation of actual driving conditions and fast output response to reduce distortions, while running a LIB beyond the specified working range will invariably affect the battery life to a certain extent, increase risks in verification, and deviate the test results. Chroma offers excellent CP output performance with output response time of less than 3.5mS and no power overshoot! Moreover, the comprehensive safety protection mechanism makes the Chroma 17011 the most fitting solution for LIB testing.
