Embodiment 1

[0026] Embodiment 1: as figure 1 , figure 2 , image 3 In the shown embodiment, an electric vehicle battery structure includes several battery unit bodies 1, the battery unit body 1 includes a casing 2, and the casing 2 includes a left bottom case and a right bottom case. 2. There are BMS, battery pack, and PCB board 11 inside. All battery tabs on the battery pack are welded to the PCB board 11. The PCB board 11 is electrically connected to the BMS. The upper cover is provided with a parallel The external charge and discharge port 23 and the internal electrical connection port 12 are both connected to the battery pack through positive and negative wires, and an outgoing line is provided on the right bottom shell The positive and negative wires are drawn out of the casing 2 through the outlet port. The outlet port is provided with a rubber plug with two holes, and the positive and negative wires are respectively connected through the two holes of the rubber plug. The intern...

Embodiment 2

[0028] Embodiment 2: the basic structure and implementation mode of this embodiment are basically the same as embodiment 1, the difference is that, as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the shell 2 is provided with an internal electrical connection port 12, the internal electrical connection port 12 is connected in parallel with the line where the charging port 22 and the discharge port 23 are located, and the internal connection between the battery cells 1 The connecting wires are all directly drawn from the internal electrical connection port 12. The internal electrical connection port 12 can be used to connect the battery unit bodies 1, avoiding confusion of lines, and improving the convenience and effect of connection. One battery unit body 1 is connected to another battery unit body 1 through a connecting frame, the connecting frame includes a tube frame 3, two pairs of locking pins 4 slidingly connected with the tube frame...

Abstract

The invention discloses a structure of an electric vehicle battery, aiming to provide an electric vehicle battery with wide adaptability, which can effectively solve the problems of too many electrical connection wires and inconvenient connection of the box head, greatly reduce problems such as crossover, wear and short circuit, etc. structure. It includes a number of battery units, the battery unit body includes a shell, the shell is provided with a charging port, a discharge port, a PCB board, a plurality of battery packs are provided in the shell, the positive electrode pad of the charging port is provided on the PCB board, and the negative electrode soldering pad of the charging port is arranged on the PCB board. Plate, discharge port positive pad, discharge port negative pad, battery pack positive pad, battery pack negative pad, solder each battery pack on the PCB, and the positive and negative pins of the discharge port should be snapped into the positive pad of the discharge port, The slots on the negative pad of the discharge port are fixed by welding each other. The beneficial effects of the invention are: using the PCB board and the welding pad to replace multiple wires together, so that the electrical connection operation of the battery box head becomes simple; the strength and connection effect can be guaranteed; the heat dissipation effect is obviously improved, and the like.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle batteries, and in particular relates to an electric vehicle battery structure. Background technique [0002] The existing electric vehicle battery market has become increasingly mature, and the scale of various manufacturers has also increased day by day. The application of secondary batteries on electric vehicles, especially batteries, has been very extensive. However, in production and life, there are often many different needs for batteries. At this time, the voltage change and power adaptability of the battery are very important. Moreover, the electrical connection of the box head in the current battery pack shell is generally connected by wires. This connection method is more complicated in operation, has many procedures, and the wires are easy to cross. After installation, wire jams may occur. During the use of the group, problems such as skin wear of the wires are prone to occur, ...
