Title:
INDEPENDENTLY CHARGEABLE CONNECTING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2023/207867
Kind Code:
A1
Abstract:
An independently chargeable connecting structure, comprising charging interfaces, battery cell interfaces, first switches or assemblies, and diodes or second switches or assemblies, wherein each diode or each second switch or assembly is connected in series between the charging interface and the battery cell interface which have the same polarity; each first switch or assembly is connected in series to the battery cell interface; the battery interface is connected to a battery; a first switch of a single connecting unit keeps normally-closed turn-on power supply for use by means of a voltage difference of the first switch itself or a battery cell; each first switch control point is in potential linkage with the charging interface, so as to switch on and off an adjacent circuit in synchronization with a charging action, and when a plurality of connecting units are connected in series and after the first switches are switched off, batteries connected to the battery interfaces are independently charged; and the plurality of connecting units are connected by means of the first switches, such that buck charging similar to parallel charging, and series discharging are realized, and the connecting units can be independently charged by means of a plurality of interfaces at the same time.
