Power battery rapid separation system and method

Abstract

The invention provides a power battery rapid separation system and method. The system comprises a slidable bracket and a vehicle body support, a battery box is fixed to the slidable bracket, sliding rolling wheels and guide rolling wheels are arranged on frames at the two sides of the slidable bracket, the sliding rolling wheels are embedded in rolling wheel sliding ways in the vehicle body support, and the slidable bracket can horizontally move along the roller slideways; a taper pin is arranged in the innermost side frame, extending into the vehicle body bracket, of the slidable bracket, andis matched with a positioning sleeve fixed on the vehicle body bracket; and the frame in the outermost side of the slidable bracket and the vehicle body bracket are fixed through a quick locking device. According to the scheme, rapid installation of the battery can be guaranteed, the normal operation requirement can be met, the battery can be rapidly separated from a vehicle body when a dangeroussignal occurs in the battery, and injuries to passengers and the vehicle are avoided.

Description

technical field [0001] The present disclosure relates to the technical field of electric commercial buses, in particular to a system and method for quickly detaching a power battery. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Power batteries are the core components of electric vehicles. Lithium batteries, which are widely used at present, form current through internal electrochemical reactions to supply drive motors; with the large-scale popularization of electric vehicles, the safety requirements for electric vehicles are getting higher and higher. When batteries In the case of internal short circuit or thermal runaway, if the battery can be separated from the vehicle body in time, it will avoid combustion and explosion of the vehicle, avoid major accidents and personal injury, so it is necessary to design a system that can quickly ...

AI Technical Summary

Problems solved by technology

[0005] The inventor found that in the existing method, most of the batteries are fixed in the car body by bolts, which cannot meet the requirement that the power battery can be quickly detached from the car body; This structure and arrangement is only suitable for large passenger cars with luggage compartments, and the battery box is small and arranged in multiple pieces. For small commercial buses, there is no luggage compartment. In order to make full use of the space efficiency of the vehicle, the battery box is single and The volume is very large, and it is hung under the longitudinal beam of the frame. The existing method cannot realize the rapid detachment of the battery of this kind of new energy bus from the car body
