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

Embodiment 1

[0029] An electric vehicle digital communication protocol testing device, the device is mainly to improve the standby part of the charging main circuit 3, because the charging control and testing software of the testing host 5 can be used without any changes, so the charging controller 4 and the working part of the test host 5 are not described in detail. Such as figure 1 with figure 2 As shown, it includes: a charging pile casing 1, a charging main circuit 3 and a charging controller 4 arranged in the charging pile casing 1, and a test host 5 connected to the charging controller 4, and the input terminal of the charging main circuit 3 is connected to the Power supply connection, the output terminal is used to connect the charging head of the electric vehicle, the charging controller 4 is connected with the charging main circuit 3, the charging head of the electric vehicle is provided with a light source 9, and the test device also includes a controlled switch 6 and a photor...

Embodiment 2

[0036] An electric vehicle digital communication protocol testing device, such as figure 1 , 2 As shown in and 4, it includes: a charging pile casing 1, a charging main circuit 3 and a charging controller 4 arranged in the charging pile casing 1, and a test host 5 connected to the charging controller 4, the charging main circuit 3 The input terminal is connected to the power supply, and the output terminal is used to connect the charging head of the electric vehicle. The charging controller 4 is connected to the charging main circuit 3. It is characterized in that the test device also includes a light source 9, a controlled switch 6 and a photosensitive Resistor 7, the controlled switch 6 is set on the charging main circuit 3, and the control signal input terminal is connected to the photoresistor 7, and the charging head of the electric vehicle is provided with a light source for reflecting the light emitted by the light source 9 to the photoresistor 7 After the charging hea...

Embodiment 3

[0039] The significant difference between this embodiment and the first embodiment is that the positions of the plug and the socket 2 are changed. The electric vehicle is the socket 2, the charging pile is the socket 2, and the photoresistor 7 is arranged on the plug. The rest are all the same as in Example 1.

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 ...
