Problems solved by technology

During use, especially as the charging power increases, the current passing through the tabs will also increase. The tabs may be disconnected from the protection board. At the same time, the disconnection of the tabs will directly cause the battery to fail to supply power. , which will affect the normal use of the terminal
Most users will think that the terminal is damaged or the battery is damaged, and it is difficult to find that the fault is caused by the disconnection of the tab

Abstract

The invention discloses a battery, a terminal and a battery open circuit detection method. The battery comprises a protection plate which is provided with a control circuit for controlling a cell anda detection circuit for detection; and a battery cell which comprises a battery cell main body and positive and negative tabs arranged on the battery cell main body, and connected with the protectionplate. At least one tab comprises a main pole part, an auxiliary pole part and a connecting part; the main pole part and the auxiliary pole part are connected through the connecting part, the main pole part is connected to the control circuit, the main pole part and the auxiliary pole part are both connected with the detection circuit, and the detection circuit is used for detecting a voltage value between the main pole part and the auxiliary pole part. According to the battery provided by the embodiment of the invention, the connection state between the tabs and the protection plate can be detected, the fault detection efficiency and accuracy are improved, and subsequent maintenance and other operations are facilitated.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a battery, a terminal and a method for detecting battery disconnection. Background technique [0002] In the related art, the tabs are mostly used as a connecting piece between the protective plate and the main body of the battery cell. During use, especially as the charging power increases, the current passing through the tabs will also increase. The tabs may be disconnected from the protection board. At the same time, the disconnection of the tabs will directly cause the battery to fail to supply power. , which will affect the normal use of the terminal. Most users will think that the terminal is damaged or the battery is damaged, and it is difficult to find that the fault is caused by the disconnection of the tab. Contents of the invention [0003] This application proposes a battery to automatically detect the connection state between the tab and the protectio...
