Problems solved by technology

These may cause uneven distribution of front and rear axle loads of the vehicle, poor safety, and inconvenient battery thermal management.
If it is placed under the chassis, it will not only be less safe, but also greatly reduce the ground clearance of the vehicle, resulting in poor driving comfort and road adaptability, and even a lot of modifications to the body floor

Embodiment Construction

[0016] refer to Figure 1A , 1B and Figure 2A , 2B , the vehicle 100 employing the battery arrangement according to the embodiment of the present invention will be described.

[0017] In addition, in the following description, the power battery assembly mounted on the vehicle 100 can be not only a secondary battery, but also a fuel cell, etc.; Any one of acid storage battery, lithium-ion battery and nickel metal hydride battery, or other batteries. Hereinafter, a method of arranging the secondary battery (lithium ion battery) will be described.

[0018] Such as Figure 1A , 1B and Figure 2A , 1B as well as image 3 As shown, the upper surface 6 and the lower surface 7 of the front power battery assembly 1 and the rear power battery assembly 2 are at the same height. The luggage case 10 is arranged between the upper surface 6 of the power battery pack and the rear view line 9, so as to ensure that the luggage case has sufficient volume and sufficient rear view. The l...

Abstract

The invention discloses an arrangement structure for a power battery assembly of an electric automobile with two seats; the power battery assembly is arranged at a rear seat place of a passenger cabin and a spare tire place below a trunk and is arranged between a left longitudinal beam and a right longitudinal beam; the shape of a battery is designed according to the left longitudinal beam, the right longitudinal beam, a transverse beam, an internal structure of an automobile body and a floor of the automobile body. The arrangement structure ensures enough back view and space of the trunk while ensuring key technologies such as the axle load distribution of the whole automobile, safe collision and the like. The arrangement structure for the power battery assembly can simultaneously meet the maximization of capacity and volume of the battery and achieve the goal of the minimization of the automobile body modification; and the arrangement structure has advantages of convenient installation and disassembling, attractive arrangement, convenient management and the like.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to the integration technology of the electric vehicle, and in particular to the layout structure of the power battery assembly of the electric vehicle. Background technique [0002] As a representative of new energy vehicles, electric vehicles have been widely known for their advantages such as energy saving, environmental protection, zero emission, and low noise. However, there are problems such as safety, reliability, and insufficient driving range. In order to ensure better safety and reliability of electric vehicles in use, and to improve the mileage of electric vehicles, it is necessary to adopt a reasonable layout and increase the capacity and volume of the battery pack as much as possible. As a result, the installation space of the power battery assembly on the vehicle is extremely limited. [0003] Due to the large number of traditional auto parts and the fixed structure o...
