    摘要: A battery pack relating to the field of batteries includes a battery module, a coolant and a battery box. The battery module and the coolant are disposed in the battery box. The battery module is at least partially immersed in the coolant. A sealing layer containing a barrier liquid is covered on the coolant. The heat generated by the battery cell which occurs thermal runaway is taken away rapidly by using the vaporization latent heat of the coolant, to thereby avoid heat accumulation and prevent propagation of thermal runaway among battery cells, thereby protecting the safety of the battery pack.

    摘要: 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.

    摘要: A battery pack and a liquid leakage detection method thereof are provided. The battery pack comprises a plurality of 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 comprising a box body and a cover plate. The isolated liquid is a fire-retardant and insulating liquid that has a specific gravity smaller than an electrolyte and is insoluble in the electrolyte. A collection portion is disposed at the bottom of the battery box, and a detection component is disposed in the collection portion. The present disclosure encloses the leaked electrolyte in the fire-retardant isolated liquid and uses the detection component to detect a resistance value of the isolated liquid so as to improve the safety of the box body.
