Embodiment approach

[0037] As another preferred embodiment of the present invention, the battery storage platform further includes an interface for a charging power line, an interface for a communication line, and a locking structure for battery storage. In this way, the battery storage platform can not only store the power battery, but also charge the replaced power battery so that it can be used next time. The battery storage platform can be provided with a charging power line interface and a communication interface respectively, or can be provided with an integrated charging power line and communication line interface. As a further preferred embodiment, the interface of the charging power line and the interface of the communication line may be in the form of a plug, a contact or a lead. By setting the battery storage locking structure on the battery storage platform, after the power battery is put into the battery storage platform, the battery storage platform can automatically or manually loc...

Abstract

The invention provides a power battery replacing system and a power battery replacing method for an electric vehicle. The replacing system comprises hoisting equipment, hoisting support points, replacing equipment and a battery storage platform, wherein the hoisting equipment is a hydraulic hoisting actuator, an electric hoisting actuator or an electro-hydraulic combined hoisting actuator, and is used for fixedly supporting the electric vehicle to a suitable height from the ground, wherein the suitable height meets requirements on the minimum distance of the replacing equipment from the ground; the hoisting support points are rigid components and are symmetrically and vertically arranged on the two sides of the central axis of the electric vehicle, and during hoisting, the body of the electric vehicle is directly supported by the hoisting support points so as to ensure that the vehicle body is stable in a battery replacing process; the replacing equipment removes the power battery arranged below a body chassis from the electric vehicle, downwards moves the battery to separate the battery from the body and stores the battery on the battery storage platform for charging; and the battery storage platform has a frame structure or a multilayer frame structure and is used for providing functions of storing the power battery storage and charging the power battery.

Description
