Problems solved by technology

[0004] In the existing technology, the power battery box is usually arranged in a centralized manner, which does not make full use of the existing internal structure of the car in terms of structural design, the installation position is unreasonable, the arrangement is not compact enough and the capacity is small
For example, some power battery boxes are arranged in the trunk, which not only takes up most of the trunk space, but also easily causes uneven distribution of front and rear axle loads; The ground clearance becomes smaller, requiring major changes to the underbody, which not only costs a lot, but also affects driving comfort

Abstract

The invention discloses a power battery system and an electric vehicle comprising the power battery system, belonging to the technical field of electric vehicles. The power battery system includes: a cooling device and a power battery box, the power battery box includes a front box and a rear box with a split structure; both the front box and the rear box have air inlets and An air outlet, the air outlet on the front box is connected to the air inlet of the rear box through the first air duct; the heat dissipation device includes an exhaust fan located at the air inlet of the front box. The power battery system can make full use of the existing body structure without major changes to the body floor. The design is reasonable, the distribution of front and rear axle loads is more uniform, the layout is compact, the space capacity is large, and it can quickly and efficiently dissipate heat.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a power battery system and an electric vehicle including the power battery system. Background technique [0002] With the increasingly severe energy and environmental problems, the concept of energy conservation and environmental protection has been deeply rooted in the hearts of the people. Because electric vehicles have significant advantages such as high energy efficiency and low emissions, as a "green vehicle", they have attracted worldwide attention. [0003] The power battery is the core component of the electric vehicle, and its performance directly affects the performance of the electric vehicle. Multiple single power batteries form a power battery module, and the power battery module can be placed in the power battery box. In order to increase the driving range, it is necessary to increase the capacity and volume of the power battery box to accommodate more p...
