Abstract
Disclosed are a device and a method for testing a battery equalization circuit. The device includes: multiple voltage supply modules, each of which being connected to a corresponding equalization module to form multiple test loops, and being configured to supply simulated voltage of the battery cell to a corresponding equalization module; multiple equalization current detection modules, each of which being configured to detect equalization current of each test loop; multiple switch assemblies and multiple leakage current detection modules, each switch assembly being connected in parallel with a corresponding leakage current detection module, and each leakage current detection module being configured to detect leakage current generated by a corresponding equalization module when the leakage current detection module is connected into a corresponding test loop; and a control module, configured to control each switch assembly and each equalization module to detect the equalization current and the leakage current of each test loop.
