The insertion charging mode has the following defects: 1. the initial investment cost of the battery is high, and the popularization of the electric automobile is hindered to a certain extent; 2. the charging time is too long, at least 2-4 hours, and compared with the oiling of a common automobile, the charging time of the electric automobile is too long, so that the charging is not convenient and fast, and the requirements of people cannot be met. The fast charging mode may cause great damage to the battery, resulting in shortened service life of the battery. The problem of the plug-in charging mode can be effectively avoided by adopting the mode of replacing the battery, and various battery box and battery frame structures are correspondingly developed in recent years. Because the quantity of the power batteries is large, the size is large, and the stability of the whole vehicle is considered, the battery frame is generally arranged at the chassis position of the electric vehicle, when the batteries need to be replaced, the battery frame is only required to be lowered to the ground, the batteries with insufficient electric quantity are pulled out, the fully charged batteries are pushed in, and then the battery frame is lifted and retracted to the vehicle chassis, so that the battery replacement can be completed. However, for a small-sized electric automobile, due to the fact that the chassis is low, the battery replacing space formed after the battery frame descends to the ground is narrow, battery replacing operation is inconvenient, and battery replacing efficiency is low.
