Chroma 87001 16Ch Battery Cell Simulator

Chroma 87001 Battery Cell Simulator is a highprecision, programmable, and bidirectional DC power source with both voltage source and current source functions. In addition, the model can be used as a multi-channel DC power supply or an electronic load as well. A single simulator has 16 channels and each of them can set voltage and current respectively via Chroma software.

The Chroma 87001 Battery Cell Simulator can be used in place of lithium-ion batteries to provide a reliable and safe testing environment. The equipped battery management system (BMS) and its subsystems can test the battery cells used in electric vehicles and energy storage batteries, etc.

The Chroma 87001 Battery Cell Simulator can be used alone with user development software or integrated into a fully functional BMS test system for automated testing to complete the product verification rapidly. The simulator can test the BMS products under master/ slave or independent architecture. Optional high-precision temperature simulation is available through Chroma's customized BMS test system as each battery has temperature sensor simulating function to provide the cell temperature status to BMS for testing.

The simulator has a variety of protection features such as over current protection (OCP), over voltage protection (OVP), under voltage protection (UVP), fan fail protection, and output circuit compensation voltage to make sure that the tests are conducted under a safe environment.


The Chroma 87001 Battery Cell Simulator has voltage source and bidirectional current source modes with a built-in 16-bit high-precision A/D converter. The voltage measurement accuracy is up to ±1mV (0.02%FS) with resolution up to 0.1mV.

For the market trend of active and passive balance design, the current measurement is divided into four ranges, 0~9A (<500ms), 0~5A, 0~500mA and 0~250uA, with 0.02%FS accuracy. For 0~5A (power increased in parallel connection) range, the accuracy is ±1mA, which meets most of the industry's requirements for testing the actively balancing designed circuits with a current measurement resolution up to 100uA.

For 0~500mA range, the accuracy is ±100uA (0.02%F.S.), which can meet most of the industry's passive balance designs, and the measurement resolution is up to 10uA. In addition to the passive balance for current measurement, it can also be used for cell supervising circuit to measure the current consumption of each battery cell (> 10mA for general consumption).
