Battery replacing control method and system for electric vehicle

Abstract

The invention discloses a battery replacing control method and system for an electric vehicle. A battery mounting frame is arranged on a vehicle body of the electric vehicle. The battery replacing control method comprises the following steps that A, a first battery is taken from the electric vehicle by battery replacing equipment; 2, a stacking machine takes the first battery from the battery replacing equipment; C, the stacking machine conveys the first battery to a battery bin; D, the stacking machine takes a second battery from the battery bin; E, the stacking machine conveys the second battery to the battery replacing equipment; and F, the second battery is mounted on the battery mounting frame by the battery replacing equipment. The battery replacing control method and system for theelectric vehicle achieve precise alignment and automatic control when the batteries are transferred among the electric vehicle, the stacking machine, the battery replacing equipment and the battery bin by using multiple sensors and specific lock structures, the error probability in the process of battery replacing is reduced, and the safe reliability of battery replacing and the battery replacingefficiency are improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and system for a battery replacement control system of an electric vehicle. Background technique [0002] With the development of new energy vehicle technology and national policy support, the production of electric vehicles has increased year by year. Due to the space limitation of the vehicle and the technical constraints of the battery module itself, the batteries of electric vehicles need to be charged frequently. How to complete the charging of electric vehicles quickly and efficiently has always been a major problem hindering the development of electric vehicles. In order to solve this problem, more and more attention has been paid to electric vehicles with battery quick-change mode. [0003] The existing battery replacement control system includes four modules: clamping lane, battery replacement trolley (namely battery replacement equipment), palletizer...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the low degree of automation of positioning control, low positioning accuracy, easy to make mistakes, low safety and reliability and problems of battery replacement in the entire process of battery replacement in the prior art. The defect of slow power supply provides a fully automatic and high-precision control of mutual alignment and cooperation between various devices in the process of centralized management and control to reduce the error rate in the process of power change, improve the safety and reliability of power change and improve Battery swapping control method and system for electric vehicles with battery swapping efficiency
