Abstract

The invention relates to a power battery module and a battery box thereof. The power battery module comprises a battery box for battery installation and a power joint which is used for passing throughthe battery box and is connected to the battery. The battery box comprises a box body and a box cover used for buckling the top of the box body. One side of the box cover in the length direction is provided with a sunken structure, which is provided with a power interface for installation of the power joint. In comparison with the prior art, the structure of the battery module is more adaptive than a battery installation structure or a connecting structure on a low speed vehicle, and the battery module is convenient to use. in comparison with the prior art, the invention has the following beneficial effects: by the top lead-out mode, cabling can be conducted through the sunken structure, cables on the top of the box body are avoided from being pressed, the structure of the battery moduleis more adaptive than a battery installation structure or a connecting structure on a low speed vehicle, and the battery module is convenient to use.

Description

technical field [0001] The invention relates to a power battery module in the field of power batteries and a battery box used in the module. Background technique [0002] Low-speed electric vehicles refer to simple four-wheel pure electric vehicles with a speed of less than 70km / h, and their shape, structure, and performance are similar to fuel vehicles. From 2013 to 2016, the number of low-speed electric vehicles in China increased from 310,000 to 900,000, showing a strong growth trend. It is estimated that the annual output will exceed 2 million vehicles in 2020, with an average annual compound growth rate of 26%. Shandong is the largest four-wheel electric vehicle market in the country. In 2016, Shandong Province produced and sold 622,600 and 618,300 small electric vehicles, an average increase of 47.76% year-on-year, accounting for more than 50% of the national total. At present, more than 90% of the low-speed electric vehicle market uses 12V lead-acid batteries that ...
