Abstract

The invention discloses an electric car chassis with a lithium battery. The electric car chassis with the lithium battery comprises a drive motor, a transmission shaft, a rear drive axle, a power-assisted steering pump, a radiating water tank, a high-pressure control cabinet, an electric air compressor and a power battery pack. The drive motor is arranged below a car body bottom plate between front wheels and rear wheels and is connected with the rear drive axle through the transmission shaft. The power battery pack is formed by connecting a first middle battery pack, a second middle battery pack, a tail high-position battery pack and a tail low-position battery pack in series. Maintenance doors are arranged in the space of the first middle battery pack and the space of the middle second battery pack respectively, and the tail high-position battery pack is placed in a tail luggage bin above the car body bottom plate. According to the electric car chassis with the lithium battery, by the adoption of the above mode, the arrangement is compact, and pipelines are mounted and connected conveniently; the power battery pack is arranged on the two sides of the middle of a car and above and below the tail luggage bin; the maintenance doors are formed in a car body, so that parts in the car do not need to be dismounted during maintenance and repair; maintaining and repairing can be facilitated, and the workload of maintaining and repairing is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a lithium battery electric vehicle chassis. Background technique [0002] Energy saving and environmental protection are one of the main directions of automobile development. Electric vehicles have been paid more and more attention to as an effective means of reducing pollution and emissions. Lithium batteries have high voltage platform, high specific energy, low self-discharge, and cycle performance. Good and other advantages become the dominant power source of electric vehicles. The existing lithium battery electric vehicle chassis includes power steering pump, cooling water tank, high-voltage control cabinet, electric air compressor, drive motor and power battery pack. The power battery pack is arranged in the middle, and the power battery pack is located between the front and rear wheels. between and under the underbody. With such a structure, it is necessary to disassemble the i...
