Power battery system and electric automobile comprising same

Abstract

The invention discloses a power battery system and an electric automobile comprising the same, and belongs to the technical field of electric automobiles. The power battery system comprises a heat radiating device and a power battery box body, wherein the power battery box body comprises a front box body and a rear box body which are of a split structure, the front box body and the rear box body are provided with air inlets and air outlets, the air outlet in the front box body is connected with the air inlet of the rear box body by virtue of a first air pipe, and the heat radiating device comprises an exhaust fan located at the air inlet of the front box body. The power battery system is capable of fully utilizing an existing vehicle body structure, is reasonable in design without largely improving a chassis of a vehicle body, ensures that a front shaft load and a rear shaft load are uniformly distributed, and is compact in arrangement, large in space capacity, and capable of rapidly and efficiently radiating 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...

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
