Description

Quick replacement device of low-speed vehicle lithium cell Technical Field The utility model belongs to the technical field of lithium battery replacement, and particularly relates to a quick replacement device for a lithium battery of a low-speed vehicle. Background Along with the enhancement of environmental awareness and the demand of energy conservation and emission reduction, low-speed vehicles, such as electric quadricycles, are increasingly widely applied to daily life and short-distance transportation, and most of the low-speed vehicles adopt lithium batteries as power sources, and the lithium batteries have the advantages of high energy density, long service life, high charge and discharge efficiency and the like. However, the charging time of the lithium battery is long, which limits the convenience of use of the low-speed vehicle to some extent. Traditional change operation generally needs to dismantle the back with the lithium cell on the low-speed vehicle, reinstallation on the low-speed vehicle with the lithium cell that is full of electricity, but because the lithium cell changes the in-process and need transport, the weight of lithium cell is great, on the key link-battery location and the connection of change battery, the lithium cell transportation process can be comparatively complicated to make battery location deviation easily lead to the installation not in place, it is unstable to cause group battery frame and vehicle connection, and connect bad problem can directly influence the power transmission of vehicle more, causes potential safety hazards such as outage even in the driving process.
