Abstract

The invention provides a secondary battery replacement assembly and replacement method for an electric vehicle. The secondary battery replacement assembly comprises a pair of guide rails which are arranged on the body of the electric vehicle along the length direction of the electric vehicle, and a drawer-type secondary battery pack, wherein a first side of the drawer-type secondary battery pack slides along a guide rail to drive a secondary battery pack in the drawer-type secondary battery pack into and out of the vehicle body, and a second side of the drawer-type secondary battery pack opposite to the first side forms a partial housing of the vehicle body. The auxiliary battery pack of the invention can slide out and then exit from the bottom, can avoid the subframe at the bottom, does not need to open the back-up tire box when changing power, does not interfere with the power changing process and the rear storage space of the vehicle owner, does not need to be lifted, greatly reduces the power changing difficulty of the electric vehicle, and improves the power changing efficiency.

Description

technical field [0001] The invention relates to the field of battery replacement for electric vehicles, in particular to a sub-battery replacement assembly and replacement method for electric vehicles. Background technique [0002] The cruising range of a car has always been a concern for consumers when purchasing electric vehicles. Sudden power feeds make the vehicle unable to drive, or lack of power on high speeds leads to dangerous accidents. This is also a pain point in the products of pure electric new energy vehicle companies. [0003] Existing technology: In order to improve the cruising range of pure electric vehicles, there are currently two main solutions: [0004] 1. Increase the volume of the main battery pack under the floor and extend it around. However, limited by the boundaries of man-machine, chassis sub-frame, etc., the expansion is limited. [0005] 2. Research and develop new technologies, such as solid-state batteries, graphene batteries, etc., to incr...
