In order to increase the number of charging stations that can be used, there are a number of proposals for motor vehicle users to obtain the power required by the electric motor vehicle through various available power outlets. However, since the electric motor vehicle also needs to be additionally equipped with a power plug to be charged with the charging station, if the power socket specification of the charging station is not in conformity with the electric motor vehicle, the resistance of the electric vehicle charging station will still be promoted.

The invention discloses a wireless charging system for an electric motor vehicle, which comprises a wireless power receiver and a wireless charging device. The wireless power receiver is disposed in an electric motor vehicle. The electric motor vehicle includes at least one guide wheel. The wireless charging device includes at least one wheel mount and a wireless power transmitter. The at least one wheel base is configured to engage the at least one guide wheel. The wireless power transmitter is configured to transmit radio energy to the wireless power receiver when the at least one guide wheel is engaged with the at least one wheel base, so that the wireless power receiver receives the power and then charges the electric motor vehicle . When the at least one guide wheel is engaged with the at least one wheel base, the wireless power receiver is located on a transmission path of the wireless power transmitter transmitting radio energy.

The invention also discloses a wireless charging device for an electric motor vehicle, comprising at least one wheel base and a wireless power transmitter. The at least one wheel base is configured to be engaged with at least one guide wheel of an electric motor vehicle.

The present invention additionally provides a notification mechanism for the three-wheeled motor vehicle 210 in motion to provide a notification message for at least one charging station within a certain range for the three-wheeled motor vehicle 210 whose current power is lower or lower than a safe power. And according to the navigation information contained in the notification message, find the charging station as soon as possible to charge. The invention also provides a reservation mechanism based on the notification mechanism, which can be used to simultaneously reserve the notification message when the three-wheeled motor vehicle 210 in motion receives the notification message of the charging station near its current location. The charging station, after reaching the charging station, performs charging according to the sequential procedures of steps 502, 506, 512, and 514.

The flow chart of the notification mechanism and the reservation mechanism provided by the present invention is shown in Fig. 6, which is mainly provided to the three-wheeled motor vehicle 210 that has not been placed at the charging position of the wireless charging pad 100 of any charging station.

In step 602, when the three-wheeled motor vehicle 210 is still running or is not in the charging position of the wireless charging pad 100, the charging management server 410 is dynamic through a wireless network or a feasible wireless communication means. Continuous, periodic, or non-periodic Detecting/inquiring about the power state of the three-wheeled motor vehicle 210, or using the wireless communication device provided by the three-wheeled motor vehicle 210, actively and dynamically to the charging management server 410 via a wireless network or a feasible wireless communication means. The power state is reported continuously, periodically, or non-periodically. When the amount of power of the three-wheeled motor vehicle 210 is higher than a critical amount of power, the charge management server 410 continues to dynamically perform step 602 to monitor the amount of power of the three-wheeled motor vehicle 210. When the power of the three-wheeled motor vehicle 210 is not higher than the critical power, the charging management server 410 performs step 604.

In an embodiment of the present invention, the manner in which the charging management server 410 detects the power state of the three-wheeled motor vehicle 210 may include wirelessly communicating with the power detecting device of the three-wheeled motor vehicle 210 itself. The power detecting device can monitor the power of the three-wheeled motor vehicle 210 by dynamically detecting the operating voltage and the operating current amount of the three-wheeled motor vehicle 210, and dynamically report the power to the charging management server 410.

And when the charging management server 410 confirms that the current power of the three-wheeled motor vehicle 210 is not higher than the minimum safe power, step 604 is continued.

In an embodiment of the present invention, the critical electric quantity is determined by the estimated amount of electric power required for the three-wheeled electric motor vehicle 210 to travel for a predetermined distance or a predetermined time before the electric quantity slips to the minimum safe electric quantity. Further, the charging management server 410 normally confirms the usual traveling route and frequent mobile field of the three-wheeled motor vehicle 210 according to the positioning position of the three-wheeled motor vehicle 210 or the position information provided by the user of the three-wheeled motor vehicle 210. data. The location information provided by the user may include location information of the user's home location, work location, and the like, and the location information needs to be sent to the charging management server through the user authorization code. 410 set or register. The charge management server 410 will further utilize the data to estimate the remaining time or remaining distance that the three-wheeled motor vehicle 210 can travel again before the power slips down to the minimum safe power. The charging management server 410 determines that the amount of power of the three-wheeled motor vehicle 210 is not higher than the critical amount when the remaining time is less than the predetermined time and/or the remaining distance is less than the predetermined distance. For example, if the user of the three-wheeled motor vehicle 210 or the charge management server 410 can preset the remaining time to be three days and/or the remaining distance is ten kilometers, the charging management server 410 collects the three-wheeled motor vehicle according to the above-mentioned collection. The relevant data of 210 calculates the estimated power required for the three-wheeled electric vehicle 210 to travel for three days and/or the ten-kilometre plus the electric quantity of the minimum safe power. As such, when the charging management server 410 performs step 602 to confirm that the current power value of the three-wheeled motor vehicle 210 is not higher than the minimum safe power plus the estimated required power, the charging management server 410 proceeds to step 604. The predetermined time or the predetermined distance is determined according to an instruction issued by the holder of the three-wheeled motor vehicle 210 to the charge management server 410, or according to a preset setting of one of the charge management servers 410.

In step 604, the charging management server 410 detects the current position of the three-wheeled motor vehicle 210, the charging permission state of at least one charging station within a predetermined range of the three-wheeled motor vehicle 210, and the three-wheeled motor vehicle 210 and the at least one charging. The distance between the stations. In step 606, the charging management server 410 transmits the location information and/or the navigation information of the at least one charging station to the three-wheeled motor vehicle 210 and/or the electronic device equipped by the holder thereof by sending a notification message. The motor vehicle charging application is installed so that the motor vehicle holder can select one of the charging stations as a charging station ready to charge the three-wheeled motor vehicle 210. After the charging station is selected, the charging management server 410 can navigate the three-wheeled motor vehicle 210 and its holder according to the location information and/or navigation information contained in the notification message, so as to smoothly reach the location. Pick the charging station.

In an embodiment of the present invention, when step 604 is performed, the charging management server 410 will only include a charging station whose charging permission status is in a usable state as a charging station candidate list. The charging management server 410 will provide the charging station candidate list to the three-wheeled motor vehicle 210 for selection.

In an embodiment of the present invention, the manner in which the three-wheeled motor vehicle 210 selects the charging station may include: (1) the user of the three-wheeled motor vehicle 210 selects any charging station to prepare for charging according to the information of the charging station candidate list; And (2) the three-wheeled motor vehicle 210 selects the optimal charging station selected by the screening algorithm program through the screening algorithm program installed by the charging management server 410; for example, the screening algorithm program can be based on the three-wheeled motor vehicle 210 lines. The linear distance, the travel distance, the predetermined travel time, and/or the charge estimation fee to each candidate charging station on the charging station candidate list are used to charge the total priority of all candidate charging stations to select the total priority The higher charging station acts as a charging station for charging the three-wheeled motor vehicle 210; the shorter the straight line distance, the shorter the travel path, and the shorter the scheduled travel time (taking into account the main factors affecting the travel time, such as road conditions or traffic conditions), charging pre-charge Estimated charge is less (because the charge for each charging station is not the same, it may also be determined by the needs or preferences of the charging station renter) The charging station can obtain a higher total priority on the charging station candidate list, and is more likely to be selected by the screening algorithm program.

After selecting the charging station, the user of the three-wheeled motor vehicle 210 can selectively subscribe to the charging station selected in the charging station candidate list, so that the selected charging station is prohibited from being the other three-wheel motor for a predetermined time in the future. Charge the car or equipment. This is the reservation made by the charging station subscribed in steps 512 and 514 for the subscriber, and at step 512 with In step 516, the charged charging station is prohibited from charging the object other than the subscriber's three-wheeled motor vehicle. The predetermined time reserved for the reservation of the user of the three-wheeled motor vehicle 210 may be based on the distance between the three-wheeled motor vehicle 210 and the selected charging station at that time, or the three-wheeled motor vehicle 210 that is to select the selected charging station at that time. The number can be dynamically adjusted, or a fixed preset time can be selected in advance to wait. In one embodiment of the invention, the shorter the distance between the three-wheeled motor vehicle 210 and the selected charging station, or the greater the number of electric motor vehicles that are to select the selected charging station at that time, the reservation is retained. The shorter the time, the longer the opposite.
