System and method for quickly replacing electric bus batteries

Abstract

The invention discloses a system and a method for quickly replacing electric bus batteries. The batteries are arranged above battery replacing robots instead of being arranged at an original position, so that the robots can acquire the charged batteries from above without turning around, and then the batteries can be replaced by the battery replacing robot on the sides as same as those of the battery replacing robot, so that occupied space of the batteries is saved, a turning mechanism of the battery replacing robot is omitted, equipment structure is simplified, and reliability and replacing efficiency of equipment are further improved. The system comprises charging storage rack units with the charged batteries thereon, at least one lifting battery replacing robot on the side as same as that of the corresponding charging storage rack unit is arranged and matched with the corresponding charging storage rack unit, each lifting battery replacing robot moves along the length direction of the corresponding charging storage rack unit, and is used for taking the batteries needing to be replaced down from an electric bus, lifting the batteries needing to be replaced to a battery storage position on the corresponding charging storage rack, taking the charged batteries and descending to a battery replacing position to complete battery replacement of the electric bus.

Description

technical field [0001] The invention relates to a battery replacement system, in particular to a quick battery replacement system for an electric bus and a battery replacement method thereof. Background technique [0002] With the continuous increase of the dual pressure of resources and the environment, in order to alleviate the shortage of oil resources and reduce the pollution of automobile fuel to the environment, the development of new energy vehicles has become the direction of the future development of the automobile industry. However, in practical applications, due to the limitation of the current battery energy density, the cruising range of electric vehicles is generally between 100 kilometers and 200 kilometers, which is far less than that of traditional vehicles. Therefore, whether energy supply can be quickly provided for automobiles directly affects the popularization and application of electric vehicles. Typically, slow charging a battery takes hours to compl...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the current electric vehicle battery replacement system is limited to the rotary replacement method in the battery replacement method, which makes the whole structure complex and occupies a large area. The bus battery quick replacement system and its battery replacement method change the traditional battery placed behind the battery replacement robot to be placed above the battery replacement robot, so that the robot no longer needs to turn around to obtain a fully charged battery from above. battery, and then the battery replacement operation can be completed on the same side of the robot through the battery replacement robot, which not only saves the space occupied by the battery, but also reduces the turning mechanism of the battery replacement robot, simplifies the equipment structure, and further improves the reliability of the equipment and replacement efficiency
