16CH Battery Cell Simulator

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 0~5.2A/0~520mA two ranges 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.

The battery cell simulator has 16 channels that can set the voltage and current limit respectively; program the rise and fall of output voltage, and synchronize the start-up between channels via software. When the low output noise features presents the DC characteristics of a battery cell without any ripples during dynamic load changes, it can quickly provide a steady DC output. Meanwhile, it reduces the surge voltage caused by the load change that could damage the UUT. For non-static products or test applications, it can supply a stable DC voltage source in time.
