In the intelligent charging control box; the protection system includes an anti-leakage module and a 36V independent power supply. The wired charging module and the wireless charging module are both installed in the intelligent charging control box. One end of the 36V independent power supply is connected to the mains, and the other end is connected to the wireless charging transmitter. An independent wireless charging transmitter is provided at the upper left corner of the wireless charging parking device. Six wired charging sockets are provided on the horizontal railing, and each socket is equipped with a charging indicator light. Four wireless charging parking devices are provided on the ground below the left side of the horizontal railing. The wireless charging receiving end is installed on the side of the front wheel of the electric bicycle, and the receiving end is connected to the battery of the electric bicycle.

[0017] When an electric bicycle needs to be charged, after entering the charging station, choose the corresponding charging pile according to whether the electric bicycle is wired or wirelessly charged. If it is a wired charging electric bicycle, choose a wired charging pile with a socket. If it is a wireless charging electric bicycle, choose a wireless charging pile. After parking at the corresponding position, scan the code in the WeChat applet to select the charging method, and you can charge after the charging time. After receiving the instruction from the WeChat applet. The control module MCU sends a control instruction, closes the relay at the corresponding position, and supplies power to the entire charging pile. The electric vehicle is ready for charging and can be charged.

[0018] For electric bicycles without wireless charging modules, when charging is needed, park the electric bicycle in a place where it is convenient to connect the charger to the electric bicycle and the charging socket. After parking, connect the electric bicycle charger to the electric bicycle and the charging socket. Then scan the QR code on the charging pile at the corresponding position to enter the WeChat applet, select wired charging, and the charging time. The WeChat applet sends a control instruction to the MCU, and the MCU gives a high level to close the corresponding relay, and then the socket can be powered. At this time, the power supply indicator on the socket lights up red, indicating that the socket is powered, and the wired charging electric bicycle starts charging. When charging is completed, the charging current of the electric vehicle is converted into a trickle mode, and the current sensed by the current transformer becomes weak. At this time, in order to ensure the battery of the electric bicycle and extend the battery life, the MCU issues a command to disconnect the relay, cut off the power to the socket, and no longer charge the electric vehicle. When the load is too large and the current flowing through the current transformer is too large, the MCU issues a control instruction to disconnect the relay, thereby cutting off the power, protecting the electric vehicle charging battery, and extending the charging life of the electric vehicle. After charging is completed, the WeChat applet sends a charging completion message to the electric vehicle charging user to inform him that charging is complete.

[0019] When the electric bicycle users who have installed wireless charging need to charge, they will park the electric bicycle at the wireless charging pile, close the wireless charging receiver and the wireless charging transmitter, and park at the correct position. Then scan the QR code on the charging pile at the corresponding position to enter the WeChat applet, select wireless charging, and the charging time. The WeChat applet sends a control instruction to the MCU, and the MCU gives a high level to close the corresponding relay, and then the wireless charging transmitter can be powered. At this time, the power indicator on the wireless charging transmitter lights up red, indicating that the socket is powered, and the wired charging electric bicycle starts charging. When charging is completed, the charging current of the electric vehicle is converted into a trickle mode, and the current sensed by the current transformer becomes weak. At this time, in order to ensure the battery of the electric bicycle and extend the battery life, the MCU issues a command to disconnect the relay, cut off the power to the wireless charging transmitter, and no longer charge the electric vehicle. Protect the charging battery of the electric vehicle and extend the charging life of the electric vehicle. After charging is completed, the WeChat applet sends a charging completion message to the electric vehicle charging user to inform him that charging is complete.

[0020] The device also includes a 4G communication module 1, a protection system 2, a wireless and wired control module 3, a 36V independent power supply 4, a wireless charging transmitter 5, a wireless charging receiver 6, a wireless charging parking device 7, a wired charging socket 8, a WeChat applet 9 and a charging pile framework 10.

[0021] The 4G communication module 1 is integrated in the smart charging control box, adopts the AIR700E4G communication module, and is connected to the wired control module and the wireless control module 3 to transmit all data of the charging interface system to the communication module, and then transmits the data to the WeChat applet connection, thereby achieving the purpose of data transmission and control.

[0022] The power protection module 2 is installed in the intelligent charging control box. After the AC power enters, it is connected to the air switch in parallel with the 36V independent power supply and the wired charging socket. The 220V to 5V module is connected to the power protection module, the wired control module and the wireless control module 3. The wireless charging transmitter is connected to the 36V independent power supply to protect the circuit safety.

[0023] The wired control module and the wireless control module 3 are installed inside the intelligent charging control box, including an MCU control module, a power metering detection module, a fuse and a relay. The 32 single-chip microcomputer control chip STM32F103RBT6 is used in the MCU control, and the MCU control satisfies the simultaneous control of multiple charging piles, and the simultaneous and independent charging of multiple charging piles for electric bicycles. The MCU controls the power on and off of each charging pile through the WeChat applet instructions. After the WeChat applet sends a charging instruction to the charging pile, the MCU controls the relay at the corresponding position to close, the power indicator light is on, the charging pile socket is energized, and the electric car can be charged after the electric car charger is connected.

[0024] The power metering detection module is based on the current transformer, which provides feedback to the MCU by detecting the current flowing through it. When the electric vehicle starts to charge, the current flowing through is large. When the electric vehicle is fully charged, the current is converted into trickle mode, and the current sensed by the current transformer becomes weak. At this time, in order to ensure the battery of the electric bicycle and extend the battery life, the MCU issues a command to disconnect the relay, cut off the power to the socket, and stop charging the electric vehicle. When the load is too large and the current flowing through the current transformer is too large, the MCU issues a control command to disconnect the relay, thereby cutting off the power and protecting the charging device.

[0025] The 36V independent power supply 4 is installed in the intelligent charging control box. It uses a transformer as the core to convert the 220V voltage and obtain a 36V power supply after full-bridge rectification, which is used to power the wireless charging transmitter. When the wireless charging receiver is close, the transmitter outputs a 36V voltage and a 4A current to charge the electric bicycle.

[0026] The wireless charging transmitter 5 is installed on the left side of the wireless charging parking device, connected to a 36V independent power supply, and has a wireless charging transmitter circuit board installed inside. Through a half-bridge structure inverter circuit, the input DC power is converted into a high-frequency AC power supply through a half-bridge circuit, and then the high-frequency signal is input into the resonant circuit to form a high-frequency resonance, so that the transmitting coil generates a high-frequency magnetic field. This high-frequency magnetic field will be received by the coil at the receiving end, including matching the resonant circuit, generating magnetic coupling between the coils, and transmitting energy to the receiving end.

[0027] The wireless charging receiving end 6 is installed on one side of the front wheel of the electric bicycle. When the electric bicycle is parked on the wireless charging parking device, the wireless charging transmitting end and the wireless charging receiving end are attached, and the wireless transmitting end supplies power to the electric vehicle battery through the wireless receiving end, supplying DC power to the battery for charging.

[0028] The wireless charging parking device 7 is installed below the intelligent charging control box and has a groove inside for parking the front wheel of the electric bicycle to ensure that the electric bicycle is parked neatly and in a standardized manner. At the same time, the wireless charging transmitter and the wireless charging receiver are fitted to ensure the wireless charging rate and minimize charging losses.

[0029] The wired charging socket 8 is installed on the horizontal railing of the charging pile frame, and mainly includes a power connection line, a socket and a charging indicator light, and a socket protection cover. The power connection line adopts a 220V level power line, one end of which is connected to the charging socket, and the other end is connected to the smart charging control box. It is used to indicate whether the socket is energized. When the socket is energized, the red light is on, and when the socket is out of power, the red light is off. Thereby achieving the effect of indicating that a socket is energized and improving the safety of use. The socket controls whether the socket is energized through the wired control module and the wireless control module 3. After using WeChat to scan the code and enter the WeChat applet to place an order, the WeChat applet controls the wired control module and the wireless control module 3 through 4G communication to control whether the socket is energized.

[0030] The WeChat applet 9 controls the wired control module and the wireless control module 3 through the cloud server and the 4G module. The user uses the WeChat applet to select wired charging or wireless charging, selects the charging time, and starts charging. After charging is completed, the WeChat applet sends a charging completion notification to the user.

[0031] The technical solution adopted by this utility model patent is to combine the wired charging pile and the wireless charging pile of the electric bicycle. In this utility model patent, a power protection device is used to control the two charging systems, and the same WeChat applet is also used to control the wired charging and wireless charging systems.
