Intelligent charging device for electric vehicles

Abstract

The invention relates to the technical field of electric vehicles, in particular to an intelligent charging device for electric vehicles. The technical scheme includes that the intelligent charging device comprises a single chip microcomputer; an IC (integrated circuit) card reading and writing module, a power module, a clock module, a display driving module, a data storage, a multi-channel control key, a relay driving module and an over-current and overload detection module are connected with the single chip microcomputer, the relay driving module is provided with a relay in a connection manner, the relay is provided with a voltage transformer in a connection manner, the over-current and overload detection module is connected with the voltage transformer, a power output socket is further connected with the voltage transformer, the power module comprises an alternating-current filter, a power transformer and a rectifier filter voltage stabilizer which are sequentially serially connected with one another, the alternating-current filter is serially connected with a 220V alternating-current power supply, the rectifier filter voltage stabilizer is serially connected with the single chip microcomputer, and a six-bit integrated LED display screen is connected with the display driving module. The intelligent charging device has the advantages that mutual use of IC cards can be prevented when the IC cards are used, and the intelligent charging device is low in idle power consumption and has overload and short-circuit protection functions.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an intelligent charging device for electric vehicles. Background technique [0002] The electric vehicle intelligent charging station is a kind of intelligent self-charging equipment suitable for installation and use in the centralized parking area of ​​electric vehicles in the community. At present, most of the charging stations are mainly coin-operated, that is, one coin gives 3-4 hours of charging. Time, output power to a socket, a socket allows only one charger of a user to use, and the user's own charger is plugged into the socket to charge the device. [0003] Some manufacturers reluctantly combine the functions of coin insertion and IC card swiping, and use the IC card to recharge the card for charging, which is convenient for users without looking for coins; but too many charging station manufacturers have little understanding of the encryption algorithm of the ...

AI Technical Summary

Problems solved by technology

[0006] At present, the output terminal of the charging station is equipped with a fuse as an overload short-circuit protection. When the electric vehicle charger is short-circuited or the electric power of multiple electric vehicles sharing a socket is overloaded, the fuse will be blown to stop the power supply. On the one hand, it can protect charging. On the other hand, it protects the interests of charging station operators. However, charging stations are placed in public places and are basically unattended. When a certain output terminal is short-circuited or overloaded, the fuse will burn out and that channel will be unusable. When a user inserts coins, the corresponding output terminal will no longer be able to supply power. This will not only cause maintenance troubles, but the user will not be able to recharge after inserting coins, and there will be economic disputes
