Control circuit of refrigerating air conditioner of electric vehicle

Abstract

The invention discloses a control circuit of a refrigerating air conditioner of an electric vehicle. The control circuit of the refrigerating air conditioner of the electric vehicle comprises a whole vehicle controller and a whole vehicle data acquiring terminal, wherein the whole vehicle data acquiring terminal is connected with the whole vehicle controller; the whole vehicle controller is connected with a relay, the refrigerating air conditioner and a refrigerating unit control circuit; the refrigerating unit control circuit comprises a three-phase high-voltage relay, an electromotor, a compressor, a refrigerating air conditioner control panel, a fan relay and a refrigerating unit fan which are sequentially connected with one another; the refrigerating air conditioner control panel and the three-phase high-voltage relay are connected in parallel and then are connected with the whole vehicle controller; the refrigerating air conditioner control panel is further connected with the relay; the refrigerating air conditioner is connected with a contactor; the contactor is further connected with the whole vehicle controller; and the refrigerating air conditioner and the refrigerating air conditioner control panel are further connected with the whole vehicle controller respectively. Through the circuit, a refrigerating unit can be combined to the whole vehicle according to an electrical principle, data of the refrigerating unit are monitored in real time, and data of the refrigerating air conditioner are acquired conveniently. Moreover, the circuit is simple in structure, low in cost and convenient to operate.

Description

technical field [0001] The invention relates to an electrical control circuit, in particular to an electrical control circuit of an electric refrigerated vehicle. Background technique [0002] With the development of society and the promotion of national policies, the competition among electric vehicle companies is becoming more and more fierce, and there are more and more models of electric vehicles. At the same time, with the continuous development of the logistics and transportation industry, the demand for electric refrigerated vehicles is also increasing. [0003] At present, the electrical connection of electric refrigerated vehicles on the market is only based on the traditional refrigerated unit, and the power distribution connection method is used. In terms of electrical connection, the electrical connection of the refrigerated unit has not been optimized. It is relatively cumbersome, and at the same time, the whole vehicle cannot control the refrigerating unit and...

Problems solved by technology

[0003] At present, the electrical connection of electric refrigerated vehicles on the market is only based on the traditional refrigerated unit, and the power distribution connection method is used. In terms of electrical connection, the electrical connection of the refrigerated unit has not been optimized. It is cumbersome, and at the same time, the whole vehicle cannot control the refrigerating unit and collect and exchange data

It is not integrated into the electrical principle of the vehicle, resulting in the inability of the vehicle to control and collect data from the refrigerated air conditioner

If the electrical connection of the refrigerating unit part of the electric refrigerated vehicle is not integrated into the whole vehicle principle, additional electrical connections are required, resulting in a waste of resources and a cumbersome system, which is not conducive to production and quality control
