Battery changing device for commercial electric vehicle and electric conversion system

Abstract

The invention relates to a battery changing device for a commercial electric vehicle. The device comprises a main frame, a positioning mechanism, a rotating mechanism, a lateral displacement mechanism and a push mechanism, wherein the positioning mechanism consists of a vertical positioning mechanism and a horizontal positioning mechanism; the vertical positioning mechanism is arranged in the main frame, and the horizontal positioning mechanism is arranged on the lower part of the main frame; the rotating mechanism is arranged on the lower part of the vertical positioning mechanism; the lateral displacement mechanism is arranged on the rotating mechanism; and the push mechanism is arranged on the lateral displacement mechanism. The invention also relates to an electric conversion system comprising the battery changing device. The battery changing device can automatically change a battery pack of the electric commercial vehicle; the process of assembling and disassembling the whole battery pack is completed by the battery changing device, is convenient, and has short changing time; the efficiency of battery changing is improved, so multiple times of battery changing can be completed in a unit time, the period of battery changing is shorter, a charger can charge electricity more sufficiently and has higher utilization.

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
