Embodiment Construction

[0026] Such as figure 1 As shown, the whole structure consists of a set of batteries 101, a set of battery connecting pieces 102, a frame 106, a sealing strip 105, a top cover 104, two pole protection covers 103, two battery pack management boxes 107 and 18 M5 fixing screw 108, voltage sampling wiring harness, temperature sensor and wiring harness thereof.

[0027] The structure of the framework is as figure 2 As shown, the frame is composed of two section panels 201, four L-shaped edge frame strips 202, and four fixing seats 204 for fixing the connectors. The four edge frame strips 202 and the two section panels 201 form a box for accommodating batteries. A gap (203) is opened at one end of the frame for putting in the battery during assembly. Nuts for fixing the connecting parts are pre-buried in the fixing seat, which is more convenient and quick during assembly. Except for the pre-embedded fixing nuts, the whole structure is made of FRP material.

Abstract

The invention relates to a battery pack of electric vehicle, which comprises a group of batteries and a box for containing said batteries, wherein said box has two pole protective sleeves made from insulated material at the positive and negative poles of battery. The invention uses pole protective sleeve to protect the poles of battery, to avoid short circuit of poles in accidence; in addition, the invention also comprises a connecting plate protective chamber, a voltage sampling wire channel, a temperature sensor compression block, a wire protective channel, and a seal compression bar, to improve efficiency and save cost in batch production. The invention can protect pole effectively, fix and protect the voltage sampling and temperature sampling wire, to simplify and structure and save cost.

Description

【Technical field】 [0001] The invention relates to an electric vehicle battery pack, in particular to the improvement of the box body of the electric vehicle battery pack. 【Background technique】 [0002] An electric vehicle battery pack generally includes a battery pack and a box for accommodating the battery pack. In the early 1990s, battery pack boxes were just simple boxes. Because the battery pack box body needs sufficient strength to protect the driver during use and accidents, the box body is generally made of metal materials such as stainless steel. The materials are often high in strength and easy to manufacture, and are widely used. [0003] However, such a structure is less safe, the structure itself cannot be insulated, and there is no proper protection for the poles of the battery, high-voltage conductive devices and various testing and sampling devices. In the event of an accident, the damage cannot be reduced but will be aggravated. [0004] In addition, in ac...
