Abstract
The present invention relates to a battery pack system, comprising: a plurality of battery cells, sealing fluid and a battery pack case. The battery cells are immersed in the sealing fluid in the battery pack case, which includes a box and a top cover. The case is equipped with an inlet port and an outlet port. The outlet port is connected with the inlet port through a circulation pump and a buffer vessel, forming a circular route; some sensors are configured in the buffer vessel. When an electrolyte leakage occurs in the battery pack, it is confined in the sealing fluid, preventing the electrolyte to be exposed to air and further catch on fire. When the mixed fluid circulates through the buffer vessel, the sensors detect the leakage at once and send out warnings to the battery system to increase its safety level. The leaked flammable gases are separated from the circulation channel and get released to avoid too high internal pressure and consequently break the battery box.
