Abstract

The invention discloses a lithium battery electric automobile. The lithium battery electric automobile comprises a driving motor, a transmission shaft, a back driving axle, front wheels, back wheels, an underbody and a storage room, wherein the storage room is positioned on the tail part of the automobile; the driving motor is arranged on the middle part of the automobile, and is connected with the back driving axle through the transmission shaft; a power battery pack is formed by connecting a first battery pack, a middle secondary battery pack, a tail high-level battery pack and a tail low-level battery pack in series; the middle first battery pack space and the middle secondary battery pack space are provided with access doors respectively; the tail high-level battery pack is positioned in the storage room above the underbody; the tail low-level battery pack is positioned below the tail high-level battery pack. Compared with the way of arranging the power battery pack at the middle position of the automobile, the lithium battery electric automobile has the advantages that internal components do not need to be detached during overhauling and maintenance, convenience is brought to overhauling and maintenance, the overhauling and maintenance time is shortened, the overhauling and maintenance workload is lowered, and the overhauling and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a lithium battery electric vehicle. 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 vehicles include a drive motor, a rear drive axle and a power battery pack. The drive motor is located behind the rear drive axle, the power battery pack is arranged in the middle, and the power battery pack is located between the front wheel and the rear wheel. Below the underbody. With such a structure, it is necessary to disassemble the interior components for maintenance an...
