AI Technical Summary

Technical Problem

The existing batteries cannot test the internal air pressure in real time after the injection port is packaged, resulting in poor battery safety monitoring mechanism and the inability to quantitatively analyze the internal air pressure value of the battery under different voltages in real time.

Method used

Design a battery cover, including a first cover plate with a liquid injection port and a detection component that encapsulates the liquid injection port. The detection component sends the temperature and air pressure data of the battery body to the battery management device in real time through the flexible circuit board, and the equipment makes real-time judgments. And output abnormal alarm information to control the connection circuit to be cut off.

Benefits of technology

Real-time monitoring of the internal temperature and air pressure of the battery is achieved, which improves the safety of the battery, reduces production costs, and avoids the need for reopening.

Abstract

The invention discloses a battery cover plate. The battery cover plate comprises a first cover plate and a second cover plate, the detection assembly is used for sending the detected battery main body temperature and the detected battery main body internal air pressure data to the battery management equipment in real time based on the flexible circuit board; and the battery management equipment is used for judging whether the temperature and air pressure data are abnormal or not in real time, and if the data are abnormal, the battery management equipment is also used for carrying out early warning and controlling to cut off a connecting circuit of the battery main body. With the adoption of the application, on one hand, the problem that the internal air pressure of the battery cannot be actually tested after the liquid injection port of the battery is packaged can be solved, and on the other hand, the battery cover plate does not need to be perforated again, so that the production cost of the battery is reduced.
