Secondary battery intelligent connection method and its intelligent connecting piece

Abstract

The invention relates to a protection method of secondary battery and the intelligent connection components device built-in protection circuit. The method includes: the battery protection circuit is set in the intelligent connection component, when a single cell is abnormal, the detecting module would detect and the control unit would control the electric switch to take action to cut off the cell from battery. The other cells still an intact secondary battery. The intelligent connector is L shape and is set battery protection circuit. At the end of the connector and the corner, there are location holes. The out of the location holes set conductor. Thus, the invention is easy to be manufactured. And the intelligent connector has reasonable structure, easy connecting and reliability of the capacity of the battery.

Description

technical field

[0001] The invention relates to a battery protection method and device, in particular to a secondary battery pack protection method and an intelligent connector device with a built-in protection circuit. Background technique

[0002] Under normal circumstances, a single battery cannot supply high voltage and high current, so it is necessary to connect multiple single batteries in series. For example, using a secondary battery as the power source of an electric vehicle means connecting multiple single secondary batteries in series Even group power supply. In order to facilitate connection, someone has applied for a "connecting device for electrical connection between battery pack terminals" (patent number: 94193744.5), which includes: a connecting cable with a conductive ring at each end, the conductive ring A connecting screw with a grooved head is housed in the hole for connecting said cable to one of the electrical terminals of the battery pack; an insulat...
