Description

Mobile smart charging system for electric vehicles

The present invention relates to a charging system, in particular to a mobile intelligent charging system for electric vehicles that is highly maneuverable and can be charged on the spot at the parking location of the vehicle, providing a convenient charging effect.

Green energy industry is the future trend. In line with this trend, vehicles (motorcycles or cars) that originally used oil as energy supply have gradually replaced "electricity" and developed power supply charging equipment specifically for electric vehicles. Therefore, power supply equipment has obviously become one of the indispensable energy sources in the future. With the gradual popularization of electric vehicles (motorcycles or cars), charging stations for power supply equipment (vehicles) are also indispensable facilities. The setting of charging stations must also be convenient for the public, just like the current gas stations. Once there is a need for charging, it must be convenient for the public to charge. However, due to environmental, economic and legal factors, such as difficulty in obtaining sites, rising material prices and labor shortages, and Taipower's feeder line control, the popularization of charging sites for electric vehicles (motorcycles or cars) is still some distance away from reaching the ideal state.

As for the charging setup of electric vehicles, one charging post is currently used for one parking space, using a "specific location" fixed charging post mode. In other words, electric vehicles can only be charged at the charging posts configured in parking spaces at specific locations, and the charging posts at the "specific locations" must be installed after applying for power feeding from Taipower in advance, and only then can there be electricity to provide charging. The key point is that the aforementioned environmental, economic and legal factors make it impossible for existing public parking lots or private parking lots, including community housing and commercial buildings, to configure a charging post for each parking space, which has caused the current dilemma of inconvenience in charging electric vehicles.

The purpose of the present invention is to provide a mobile intelligent charging system for electric vehicles, which can be used to charge the vehicle on the spot at the existing parking location, thereby providing a highly mobile and convenient charging effect.

Another purpose of the mobile intelligent charging system for electric vehicles of the present invention is that the mobile intelligent charging system can be self-charged with an existing fixed charging post to store electrical energy for continuous mobile charging.

Another purpose of the mobile smart charging system for electric vehicles of the present invention is that the mobile smart charging system can provide a function of selling electricity between electric vehicles and Taipower, that is, the excess electricity of the electric vehicle during parking is sold to Taipower through the system of the present invention to obtain a consideration amount, or the mobile smart charging system of the present invention directly sells the excess electricity to Taipower to obtain a consideration amount, which can achieve the effect of peak load reduction and valley filling and effective utilization of electricity.

To achieve the above-mentioned purpose, the mobile intelligent charging system for electric vehicles of the present invention includes a mobile charging vehicle and a cloud platform that controls the mobile charging vehicle to charge itself by AGV (Automated Guided Vehicle, AGV) technology, and a payment module connected to the mobile charging vehicle and the cloud platform, wherein the cloud platform includes a control module and a monitoring module, the control module includes a memory and a server, the memory is used to store the map and path information of each parking area, and the information of each parking space; the server is connected to the memory and the payment module, at least assigns an "identification code" to each parking space, and can read the "identification code" and transmit the "identification code" to the server. The monitoring module transmits the "location information" of the site map and route information of the parking location where the "identification code" is located to the monitoring module, and transmits the "payment information" of the payment module according to the activation of the mobile charging vehicle; the monitoring module is wirelessly connected to the control module, and includes a positioning navigator and a monitor, wherein the positioning navigator is set on the mobile charging vehicle to receive the "location information" of the site map and route information and then transmit the "location information" to the mobile charging vehicle, and the monitor is connected to the positioning navigator to at least display the route of the "location information".

The mobile charging vehicle is connected to the control module and the monitoring module, and includes a body and a battery energy storage cabinet assembled on the body, wherein the body has a fixed bearing, a servo drive motor; and wheels driven by the servo drive motor; and a power connection port for connecting to an external power source and a communication port for connecting to a communication element. The fixed bearing and the battery energy storage cabinet are assembled together, and the servo drive motor is activated to cooperate with the AGV technology to move automatically according to the path of the "positioning message" after receiving the "positioning message" transmitted by the positioning navigator through the communication port; the battery energy storage cabinet at least accommodates an energy storage group and a bidirectional energy storage inverter (PCS, Power Conversion System), battery management module (BMS), temperature control and heat dissipation module (TMS), and an external charging gun connected to the energy storage group are integrated with the battery storage cabinet through the fixed bearing, and connected to the charging device (Taipower feeder) through the power connection port to store electricity in the energy storage group. Once charging is required, the external charging gun is used for charging. After charging is completed, the "payment message" is transmitted to the payment module through the control module, and the bidirectional energy storage inverter absorbs or emits the electricity of the energy storage group. The battery management module monitors the battery status of the energy storage group, and the temperature control and heat dissipation module ensures that the energy storage group is maintained at the optimal working temperature.

The payment module is connected to the external financial bank payment system and receives the activation information of the mobile charging vehicle. It has a transaction unit and a payment unit. The transaction unit has a payment type interface, which is linked to the "identification code" of the control module. When the "identification code" is activated, the payment type interface releases multiple "payment option messages" to provide the charger (the one who activates the "identification code") with a choice of payment method; the payment unit is connected to the transaction unit and has a payment interface. When receiving the "payment message", the charger is deducted according to the "payment option message" of the transaction unit.
