JH8503D-12CH Battery Simulator
It features individual cell voltage simulation and the capability to emulate the voltage of a series‑connected battery pack, with each cell’s voltage designed in accordance with lithium‑ion battery voltage standards. Primarily used for verifying the accuracy of BMS single‑cell voltage measurement, it can precisely simulate fault conditions such as a single‑cell voltage exceeding a set threshold, falling below a set threshold, or exhibiting a consistency deviation greater than specified limits, thereby assessing the BMS system’s fault‑diagnosis capabilities. Additionally, each channel can both absorb and supply DC power, making it suitable for testing balancing currents.
