Electric vehicle charging device based on mobile phone short messages

Abstract

The invention provides an electric vehicle charging device based on mobile phone short messages, which comprises a mobile phone, a global system for mobile communication (GSM) terminal module, a charging circuit and a microprocessor control unit. The electric vehicle charging device is controlled by the microprocessor control unit which exchanges information through short messages with vehicle owners through a GSM network communication module. After the electric vehicle charging device takes place, the vehicle owners can start charging work on site through a button on the device or through the short messages remotely. In the charging process, the microprocessor control unit collects related information such as current, voltage and temperature and conducts prejudgment on the collected parameters. The microprocessor control unit automatically sends collected fault information to the mobile phone of the vehicle owners through short messages and sends out corresponding safety control instruction according to short message information sent back by the vehicle owners when obtaining judgment results such as overhigh / overlow alternating current voltage, output overvoltage / output undervoltage, excess temperature, current impact surge and overload.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to an electric vehicle charging device based on mobile phone short messages. Background technique [0002] The world is now facing three major problems, one is the energy problem, the other is the carbon dioxide emission problem, and the third is the urban pollution problem. Facing the increasingly severe energy situation and environmental protection situation, it is necessary to find new energy sources. Electric vehicles have the characteristics of zero emission and no pollution, low driving cost per 100 kilometers, low lifetime maintenance costs, and lower and lower manufacturing costs. Therefore, from a long-term perspective, the future transportation tools will be the home of electric vehicles. Electric vehicle charging devices can be generally divided into off-board charging devices and on-board charging devices. Usually, the power, volume and quality of off-board cha...

AI Technical Summary

Problems solved by technology

However, there will be some uncertain safety hazards in the charging process of electric vehicles, such as AC voltage is too high / low, output overvoltage / undervoltage, temperature is too high, current impact surge, overload and other issues, these information are in the electric vehicle During the charging process, the owner must be informed in time and take corresponding safety measures.
