Charging device, charging method, computer device and storage medium

Abstract

The invention provides a charging device. The charging device comprises a connection confirmation unit, a signal sending unit, a verifying unit and a control unit, wherein the connection confirmation unit is used for confirming charging connection between the charging device and to-be-charged equipment, the signal sending unit is used for sending a verifying voltage to the to-be-charged equipment after charging connection is confirmed, the verifying unit is used for receiving a voltage signal sent by the to-be-charged equipment and comparing the voltage difference between the voltage signal and the verifying voltage to judge whether preset conditions are met or not, and the control unit is used for matching the voltage signal with a charging state when the voltage signal meets the preset conditions, and controlling the signal sending unit to send a charging voltage signal to judge the charging state of the to-be-charged equipment. In addition, the invention further provides a charging method applied to the charging device, a computer device and a storage medium.

Description

technical field [0001] The present invention relates to the field of smart charging, and specifically relates to a charging device, a charging method, computer equipment and a storage medium capable of reducing charging connection failures. Background technique [0002] With the continuous improvement of the level of technology and people's living standards, more and more people start to buy vehicles to improve the convenience of life and improve the quality of life. However, due to the continuous increase of vehicle capacity, the emission of vehicle exhaust has brought a greater impact on the ecological environment. In order to improve the deteriorating ecological environment, electric vehicles have emerged as the times require. Electric vehicles drive vehicles through electricity and do not generate vehicle exhaust during driving, which has a great effect on reducing vehicle exhaust and improving environmental pollution. [0003] At present, when electric vehicles are cha...

Problems solved by technology

In the part 1 of the electric vehicle charging requirements: general requirements, that is, in the charging control pilot circuit specified in GB / T18487.1-2015, the charging pile receives six different voltage signals to judge the different charging states of the electric vehicle. However, when the charging pile and the electric vehicle are connected through the charging gun and the cable, due to the aging of the cable, there will be a voltage loss when the electric vehicle is transmitted to the charging pile through the cable, which will cause the voltage signal received by the charging pile to be inconsistent. Comply with the voltage signal in the charging control pilot circuit stipulated in GB / T18487.1-2015, causing the charging pile to fail to recognize the voltage signal and the charging state of the electric vehicle, thus causing a charging failure
