Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] see figure 1 , it can be seen from the figure that the electric vehicle power battery of the present invention is formed by a number of modular battery units connected in series, parallel or series-parallel hybrid, and all the battery units are identical. The battery unit here can be either an existing power battery or various energy storage modules capable of charging and discharging. The feature of the present invention is that the battery is a modular structure, that is, the power battery is basically composed of battery cells. Different power batteries have different battery cell numbers and series-parallel connection methods, and users can choose different connection methods according to actual driving conditions. In this way, all models can only produce one type of battery unit, and the battery is more versatile and professional. Dividing the p...

Abstract

The invention discloses a power battery for an electric vehicle, which is formed by connecting several modularized battery units in series, in parallel or in combination with series and parallel, and all the battery units are identical. The power battery adopts a modular design, which can be configured on different models, and has good versatility; when configuring, it can have different configuration forms according to the actual situation of consumers. By changing the battery, the problem of long charging time and high charging requirements is solved.

Description

technical field [0001] The invention relates to the technical improvement of electric vehicle batteries, in particular to a modular electric vehicle power battery, which belongs to the technical field of electric vehicle power batteries. Background technique [0002] As the world's energy situation continues to be severe, new energy vehicles that do not use traditional fuels are increasingly being advocated and encouraged by everyone. Among them, electric vehicles have become the key direction of enterprise research and development, and with the development of technology, they have also realized commercial applications and gradually entered people's lives. Although electric vehicles have already been driven on the road, they still face many problems, which is also an important reason for their slow development, and the main restrictive factor is the power battery. At present, the power battery mainly has the following defects: 1. The cost remains high, accounting for more t...
