Abstract

The invention relates to a method for displaying the open fault of a series battery pack. Each battery is connected in parallel with an overvoltage display circuit, thereby forming a unit; the series battery pack is formed by connecting n units in series. In the series battery pack, when a battery is in open because of the contact problem of the clamping device or self problems of the battery, the light emitting diode of the overvoltage display circuit corresponding to the battery emitts lights to show that the circuit is open to attract attention of operators to fix the open connection in time. The display circuit is simple and practical, and during the process of the mass production and formation of batteries, the display circuit can indicate the open position of the series batteries quickly and correctly, thereby improving the work efficiency of the battery formation processing.

Description

technical field [0001] The invention relates to a method for displaying open-circuit faults of series-connected battery packs, and is especially suitable for displaying and alarming the state of open-circuit faults during battery series formation. Background technique [0002] At present, the formation process in the mass production process of batteries is formed by charging and discharging dozens of batteries in series. , it is difficult to determine the position of the battery where the circuit is open, and the operator can only use the instrument to check point by point, and the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a method for displaying open-circuit faults of series battery packs, which effectively solves the technical problem that it is difficult to determine the position when a certain part of the battery series circuit is open. [0004] The technical scheme of the invention is: the display ci...
