Problems solved by technology

However, when the flexible circuit board collects voltage, the nickel terminal is connected to the battery cell to ensure reliable connection, that is, the two ends of the nickel terminal are respectively connected to the flexible circuit board and the battery cell; The cost of the sheet itself is relatively high, and it needs to be processed into the required shape of the nickel sheet, resulting in high processing costs. At the same time, in order to ensure the reliable connection between the nickel sheet terminal and the flexible circuit board, another layer of protective film needs to be pasted, while the power battery pack There are generally multiple flexible circuit boards in the battery pack, which makes the cost of the entire power battery pack relatively high

Embodiment 1

[0077] In this example, if figure 1 and figure 2 As shown, the flexible circuit board 100 is suitable for being connected between a battery management system (ie, BMS, BATTERY MANAGEMENT SYSTEM) 203 and a plurality of electric cells 201, and two adjacent electric cells 201 in the plurality of electric cells 201 pass through the connecting sheet 202 If connected, the flexible circuit board 100 is suitable to be connected between the connecting piece 202 and the battery management system 203 . Wherein, the flexible circuit board 100 is a low-voltage FPC.

[0078] figure 1 As shown, the flexible circuit board 100 includes a circuit substrate 1, and the circuit substrate 1 includes a body part 11 and a collection part 12 that are integrally punched. connected to the part 12, and the collecting part 12 is used to make the connector 2 obtain the voltage signal of the electric core 201; there are nine collecting parts 12, and the nine collecting parts 12 are arranged around the b...

Embodiment 2

[0085] Such as image 3 As shown, the structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same components use the same reference numerals, the difference is that there are five collection parts 12, and each collection part 12 extends along a straight line, and the five collection parts Each collecting part 12 is connected on the first sub-edge 1111, wherein three collecting parts 12 are connected on the upper first sub-edge 1111, and the other two collecting parts 12 are connected on the lower first sub-edge 1111.

Abstract

The invention discloses a flexible circuit board, a punching base material and a battery device. The flexible circuit board is suitable for being connected between a battery management system and a plurality of battery cells; the flexible circuit board comprises a circuit substrate, and the circuit substrate comprises a body part and a plurality of acquisition parts which are integrally punched; the plurality of acquisition parts are arranged around the body part at intervals; a connector suitable for being electrically connected with a battery management system is arranged on the body part; one end of each acquisition part is connected with the edge of the body part, the other end of each acquisition part is connected with a battery cell, and the acquisition parts are used for enabling the connector to acquire preset parameters of the battery cell. According to the flexible circuit board, the cost is low, and the processing procedure is simple.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a flexible circuit board, a die-cut substrate and a battery device. Background technique [0002] In related technologies, a flexible circuit board is used in the power battery pack to collect the voltage of the cells in the power battery pack. However, when the flexible circuit board collects voltage, the nickel terminal is connected to the battery cell to ensure reliable connection, that is, the two ends of the nickel terminal are respectively connected to the flexible circuit board and the battery cell; The cost of the sheet itself is relatively high, and it needs to be processed into the required shape of the nickel sheet, resulting in high processing costs. At the same time, in order to ensure the reliable connection between the nickel sheet terminal and the flexible circuit board, another layer of protective film needs to be pasted, while the power battery pack There are...
