Battery charging and replacing station for electric vehicles

Abstract

The invention belong to the technical fields of low-voltage power distribution and power electronics, and relates to a battery charging and replacing station for electric vehicles. In the battery charging and replacing station for the electric vehicles, battery replacement and separated-box charging take the priority and entire vehicle charging takes the secondary. The battery charging and replacing station can satisfy the requirement of replenishing electric energy for large-size commercial vehicles and small-size passenger vehicles. In addition, a warehousing type automatic battery replacing system is adopted so that the functions of automatic battery replacement and automatic warehousing in/out management are achieved, and a separated-box charging system can be used for charging the batteries.

Description

technical field [0001] The invention belongs to the field of low-voltage power distribution technology and the field of power electronics technology, and in particular relates to an electric vehicle charging and swapping station. Background technique [0002] At home and abroad, there are usually two types of charging and swapping stations for electric vehicles: [0003] 1. The electric vehicle charging station, park the electric vehicle at the vehicle charging position, use a high-power DC charger to charge the vehicle, the charging time is longer, the charging station occupies a larger area, and the effective use area is smaller; [0004] 2. Electric vehicle battery replacement station, park the electric vehicle at the exchange potential, remove the battery, replace it with a fully charged battery, and use the sub-box charging system to charge the rechargeable battery in sub-boxes. The battery replacement time is short, but a special battery replacement workshop is require...

AI Technical Summary

Problems solved by technology

[0003] 1. The electric vehicle charging station, park the electric vehicle at the vehicle charging position, use a high-power DC charger to charge the vehicle, the charging time is longer, the charging station occupies a larger area, and the effective use area is smaller;

[0004] 2. Electric vehicle battery replacement station, park the electric vehicle at the exchange potential, remove the battery, replace it with a fully charged battery, and use the sub-box charging system to charge the rechargeable battery in sub-boxes. The battery replacement time is short, but a special battery replacement workshop is required. At present, large-scale bus battery replacement stations occupy a very large area, and the battery replacement workshop needs about 400 square meters;

[0007] Currently built electric vehicle charging stations cannot fully meet the functions of charging and swapping large and small vehicles, and occupy a large area, with very low efficiency and very high construction and operation costs. Therefore, electric vehicle charging and swapping stations can only be redesigned to meet current construction needs.
