Abstract

The invention discloses a method for displaying an open-circuit fault of a series battery pack. Each battery is connected in parallel with an overvoltage display circuit, so that a unit is formed; the series battery pack consists of N units which are connected in series; when a certain battery in the series battery pack generates an open circuit due to a clamp contact problem or the own problem of the battery, a light emitting diode of the overvoltage display circuit corresponding to the battery is turned on to show that the circuit at the position is disconnected and catch the attention of an operator for handling in time. The display circuit is simple and practical; in a large-batch battery production and formation working procedure process, the open-circuit position of the series batteries can be quickly and accurately indicated, so that the working efficiency of the battery formation working procedure is improved.

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. When the battery is open, it is difficult to determine the position of the battery. 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 the open circuit fault of a series battery pack, 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 present invention is: the disp...
