BATTERY PACK AND ELECTRICAL DEVICE CONTAINING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18345515 titled 'BATTERY PACK AND ELECTRICAL DEVICE CONTAINING SAME

Simplified Explanation

The patent application describes a battery pack and an electrical device that includes the battery pack.

  • The battery pack includes a battery cell that is partially immersed in a refrigerant.
  • The battery pack also includes a case that accommodates the battery cell and the refrigerant, with an outlet and an inlet for the refrigerant.
  • A circulating pipeline is located outside the case, connecting the outlet and the inlet to form a closed system.
  • The circulating pipeline includes a heat exchanger and a condenser.
  • A pressure measuring module is provided to detect the internal pressure of the case.
  • A temperature monitoring device is used to detect the temperature of the battery cell and the fluorine-containing cooling medium in real time.
  • A battery control module manages the battery cell.
  • The refrigerant used in the battery pack includes at least two fluorine-containing cooling mediums.


Original Abstract Submitted

A battery pack and an electrical device including the same are described. The battery pack includes a battery cell at least partially immersed in a refrigerant; a case for accommodating the battery cell and the refrigerant and provided with an outlet and an inlet for the refrigerant; a circulating pipeline located outside the case, connecting the outlet and the inlet for the refrigerant to form a closed system; a heat exchanger and a condenser located on the circulating pipeline; a pressure measuring module provided with one end arranged inside the case and configured for detecting an internal pressure of the case; a temperature monitoring device for detecting a temperature of the battery cell and a fluorine-containing cooling medium in real time; and a battery control module for managing the battery cell; where the refrigerant includes at least a first fluorine-containing cooling medium and a second fluorine-containing cooling medium.
