Battery changing device for commercial electric vehicle and electric conversion system

Abstract

The invention relates to a battery replacement device suitable for electric commercial vehicles, comprising: a main frame; a positioning mechanism, which is composed of a vertical positioning mechanism and a horizontal positioning mechanism, the vertical positioning mechanism is set in the main frame, and the horizontal positioning mechanism is set in the main frame The lower part; the rotating mechanism is arranged on the lower part of the vertical positioning mechanism; the lateral movement mechanism is arranged on the rotating mechanism; the push-pull mechanism is arranged on the lateral movement mechanism. The invention also relates to a power changing system comprising a battery changing device. The battery replacement device of the present invention can automatically replace the battery pack of the electric commercial vehicle. The loading and unloading process of the whole battery pack is completed by the battery replacement device, which is very convenient and has a short replacement time. Complete more battery replacements, and the battery replacement cycle is shorter, so that the charger can be charged more fully and the utilization rate is higher.

Description

technical field [0001] The invention relates to the field of energy technology utilization, in particular to a battery replacement device suitable for electric commercial vehicles and a battery replacement system. Background technique [0002] As an important part of the new energy strategy and smart grid, and one of the strategic emerging industries identified by the State Council, electric vehicles will gradually become the focus of the development of China's automobile industry and energy industry. In the process of commercialization and industrialization of electric vehicles, especially electric commercial vehicles, how to supply energy to electric commercial vehicles is an extremely important factor. A perfect energy supply system will provide very important support for the use of electric commercial vehicles. [0003] The characteristic of electric commercial vehicles is that they have a large number of battery packs, most of which have as many as 12 sets, which takes ...

[0003]The characteristic of electric commercial vehicles is that they have a large number of battery packs, most of which have as many as 12 sets, taking up a lot of space

However, in the battery replacement facilities that have been built so far, the battery replacement devices often use semi-automatic or manual methods. For a large-scale battery replacement process, the replacement time is relatively long, and it is difficult to load and unload, requiring more manpower and material resources.

For battery exchange facilities, due to the long turnover period of the batteries of electric commercial vehicles, the utilization rate of their chargers is also relatively low
