Testing device for digital communication protocol of electric vehicle

Abstract

The invention relates to a testing device for a digital communication protocol of an electric vehicle. The testing device comprises a charging pile casing, a charging main circuit, a charging controller, and a testing host, wherein the charging main circuit and the charging controller are arranged in the charging pile casing, and the test host is connected to the charging controller. The input endof the charging main circuit is connected to a power supply, and the output end is used for connecting a charging head of the electric vehicle. The charging controller is connected to the charging main circuit, and a light source is arranged on the charging head of the electric vehicle. The testing device further comprises a controlled switch and a photo-resistor. The controlled switch is arranged on the charging main circuit, and the input end of a control signal is connected to the photo-resistor. The photo-resistor is fixed by the photo-resistor support inside the charging pile casing, andthe position where the light source can be illuminated, when the charging head of the electric vehicle is inserted. After the charging head is inserted, the resistance of the photo-resistor is decreased under the irradiation of the light source; the controlled switch is turned on, and then the charging main circuit starts to work, and the electric vehicle is charged. According to the testing device for the digital communication protocol of the electric vehicle, the method has the advantages of being safe, reliable, and the like, while compared with the prior art.

Description

technical field [0001] The invention relates to a charging pile for an electric vehicle, in particular to a digital communication protocol testing device for an electric vehicle. Background technique [0002] Although fossil fuels have various advantages, since fossil fuels are non-renewable resources, they must not conform to the concept of sustainable development and will inevitably be eliminated. On the other hand, various technologies of traditional fuel vehicles have been partially eliminated. Large manufacturers have created a technical gap, and it is almost difficult for new car companies and small manufacturers to compete with these traditional manufacturers. Therefore, electric vehicles have been paid more and more attention in recent years. First, the direct source of energy (electric energy) of electric vehicles is more environmentally friendly. Second, It is easy for new companies to overtake on corners. [0003] The bottleneck of the popularization of electric ...

Problems solved by technology

[0004] Charging piles are required for testing or actual charging. Many charging piles are placed outdoors, and may be exposed to natural conditions such as rain, or some moving objects. Cause harm, for this, most of the current charging piles are implemented with a barrier cover, but although the harm caused by natural causes is solved in this way, the main circuit is still charged, and it is still dangerous if someone accidentally touches it
