Abstract

The invention provides a charging connector, a charging device, a kit and a charging method. Among them, a charging connector for a battery pack of a new energy vehicle, the battery pack includes a plurality of sub-battery packs, the charging connector includes: a connecting wire connected to one of two adjacent charging circuits The connection point between; the connection plug communicated with the connection wire, the connection plug has a first connection terminal and a second connection terminal communicated with the connection wire, the connection plug can be connected to two adjacent sub-batteries between the groups, so that the two adjacent sub-battery groups are electrically connected to each other and to the connecting wires. The charging connector of the present invention can be obtained only by simply modifying the existing intermediate switch plug, which improves the charging efficiency and charging stability of the high-voltage battery pack in series.

Description

technical field [0001] The present invention relates to the field of charging new energy vehicle battery packs, and more specifically, the present invention relates to a method and related devices for charging new energy vehicle power battery packs (especially high-voltage battery packs). Background technique [0002] A battery pack, especially a high voltage battery pack (eg, 1000V or higher), is generally composed of a number of sub-batteries connected in series, which in turn include a number of battery cells. The voltage of the battery pack is equal to the product of the voltage of a single battery and the number of series connected batteries. When designing, the battery pack is designed with one or more intermediate connectors or intermediate switches (generally also called maintenance switches) according to the actual situation and usage needs. When the intermediate connector is taken out, the entire battery pack is divided into multiple lower-voltage sub-battery pack...
