Rechargeable battery components and terminal equipment

Abstract

A rechargeable battery assembly and a terminal device are provided, the rechargeable battery assembly includes: a battery main body, including a charging port, a fuse and an electric core, the fuse is arranged between the electric core and the charging port, and the input from the charging port The current is transmitted to the electric core through the fuse; the heater includes a control element and a heating element, the heating element is arranged near the fuse, and the control element controls the heating element to release heat when receiving a control signal; the sensor , for detecting at least one of the following parameters: the voltage of the electric core, the temperature of the electric core; the processor, for obtaining the parameter from the sensor, and after determining that the parameter satisfies a preset condition, send a control to the control element Signal. Therefore, when the voltage or temperature of the electric core satisfies the preset condition, the heating element can be made to release heat, the fusing of the fuse can be accelerated, and the use safety can be improved.

Description

technical field [0001] The present invention relates to the charging field, and more specifically, to a rechargeable battery assembly and a terminal device equipped with the rechargeable battery assembly. Background technique [0002] At present, there is known a rechargeable battery with fuse protection. By setting a fuse between the charging port and the battery cell, when the charging current is too large, the charging circuit can be cut off by blowing the fuse, thereby preventing the battery from being damaged due to excessive input. Large current may cause damage or even explosion. [0003] However, since the fuse blowing takes a certain period of time and is greatly affected by the environment, for example, in the case of low temperature, even if the current is increased, the fuse cannot be blown quickly. In this case, there is no guarantee The protection of the battery has seriously affected the safety of use. Contents of the invention [0004] Embodiments of the ...
