Light electric automobile power lithium battery pack

Abstract

The invention discloses a light electric automobile power lithium battery pack. The light electric automobile power lithium battery pack comprises a lower fixed base, lithium batteries, an upper fixedbase, a first conducting piece, a second conducting piece and a lithium battery box; four lower mounting grooves matched with the lithium batteries are formed in the top of the lower fixed base; thefour lower mounting grooves are distributed in a square shape; the bottom ends of the lithium batteries are inserted into the lower mounting grooves; the tops of the two adjacent side walls of the lower fixed base are fixedly connected with lower tenons; the tops of another two side walls of the lower fixed base are provided with lower mortises matched with the lower tenons; a first conducting hole which is through vertically is formed in the center of each lower mounting groove of the lower fixed base; and the first conducting pieces are electrically connected with electrodes at the bottom ends of the lithium batteries respectively. The four lithium batteries form a small lithium battery pack; a plurality of small lithium battery packs can be easily connected to form a large lithium battery pack by adopting mortise and tenon structures, so that different numbers of lithium batteries can be selected according to electric automobiles of different sizes; and the light electric automobilepower lithium battery pack is wide in application range and convenient to use.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a power lithium battery pack for light electric vehicles. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Electric vehicles are a type of new energy vehicles. Electric vehicles generally use lithium batteries as energy storage power sources, and provide electric energy to the motor through the battery to drive the motor to run, thereby driving the car. [0003] Existing lithium battery packs are generally assembled with multiple lithium batteries through two upper and lower fixing seats, but the assembly process is cumbersome. Different types of electric vehicles use different numbers of lithium batteries, and the size of the fixing seats...

AI Technical Summary

Problems solved by technology

[0003] Existing lithium battery packs are generally assembled from multiple lithium batteries through two upper and lower fixing seats, but the assembly process is cumbersome. Different types of electric vehicles use different numbers of lithium batteries, and the size of the fixing seats required is also different. Production; the existing electric vehicles do not have a good fixed protection for the battery. When the electric vehicle is running, when encountering a bumpy road section, the battery is easily damaged in the car along with the bumps in the car
