Battery pack system and liquid leakage detection method thereof
A battery pack system and a liquid leakage detection method thereof are provided. The battery pack system comprises battery cells, a isolated liquid and a battery box containing the isolated liquid. The battery cells are soaked in the isolated liquid. The battery box is formed with a isolated liquid outlet and a isolated liquid inlet. The outlet is connected together with the inlet via a circulation pump and a liquid separation device to form a circulation passage. When electrolyte leakage occurs to any of the battery cells, the electrolyte is separated into the liquid separation device and detected by a detection component. The present disclosure encloses the leaked electrolyte into the fire-retardant isolated liquid to prevent the electrolyte from contacting with the air so as to improve the safety of the battery box body.
