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 and a battery pack system are provided. The battery pack includes a battery box and a battery module. The battery module is disposed in the battery box. The battery module consists of a plurality of battery cells. The battery box is further filled with a sealing liquid. The battery module is at least partially immersed in the sealing liquid. At least one cooling pipe is disposed in the battery box. At least a portion of the cooling pipe is configured to melt and form a breach after reaching a preset temperature. The cooling pipe is filled with a coolant. The vaporization latent heat of the coolant is higher or equal to the heat capacity or the vaporization latent heat of the sealing liquid.
