Description

Technical Field

[0001] The invention relates to a system and method for receiving and discharging orders for an electric vehicle, and belongs to the technical field of electric vehicles. Background Art

[0002] With the continuous advancement of battery technology such as lithium-ion batteries, the endurance and battery capacity of electric vehicles (EVs) have been significantly improved. This technological breakthrough has made electric vehicles no longer just a means of transportation, but also have sufficient energy storage capacity to meet their driving needs and return excess electricity to the power grid.

[0003] In modern society, cities are densely populated, especially during certain periods, such as high temperatures in summer, when electricity demand in densely populated areas increases dramatically. For example, the use of high-power appliances such as air conditioners has brought huge power supply pressure to the power grid. Traditional solutions are mostly to deal with it through circuit transformation, transformer expansion and other means, but these methods have the problem of waste of resources and high costs. Because the increase in power supply pressure is not continuous, but occurs in specific periods or seasons, the use of these methods will cause the expanded power equipment to be idle during most periods when electricity demand is not high.

[0004] The emergence of V2G (Vehicle-to-Grid) technology provides a new idea for solving this problem. V2G technology refers to the two-way energy exchange between electric vehicles and the power grid. Through this technology, electric vehicles can not only obtain electricity from the power grid for charging, but also return the electricity stored in the battery to the power grid when the power grid needs it. This two-way energy exchange feature allows electric vehicles to play a more flexible and diverse role in the power system.

[0005] V2G technology brings new business opportunities to both car owners and power companies. For car owners, they can earn extra income by selling electricity back to the grid; for power companies, V2G technology can help them optimize grid operations, reduce operating costs, and provide backup power in power shortages or emergencies, thereby improving the reliability and stability of the power system. Summary of the invention

[0006] The purpose of the present invention is to provide a system and method for electric vehicle discharge orders, which can realize dynamic regulation of power supply of the power grid, reduce peak load and fill valley load, effectively alleviate the power supply pressure of the power grid and realize full utilization of resources through two-way energy exchange between the electric vehicle and the power grid.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions: A system for receiving and discharging orders for electric vehicles comprises: an order issuing module, a driver receiving order module, a discharging module, and a charging module; The order publishing module is used for power users to publish their power demand in the system, fill in a form, which includes the location, time, duration, power requirement, form, contact person and telephone number, and publish an order; Driver order acceptance module: Electric vehicle drivers log in to the system and select appropriate orders based on the distance and electricity conditions of the filtered orders; Discharge module: After the driver drives the electric vehicle to the designated point, he uses the discharge gun provided by the power grid to reversely supply power to the power grid according to the order requirements. After the driver arrives at the designated location to perform the discharge operation, he contacts the customer to obtain the corresponding verification code. The order can be executed only after the verification code is verified; In the billing module, the backend will calculate the cost of the order based on the duration and discharge amount of the order. The customer pays the order and the order is completed. Preferably, the functions of the driver order acceptance module are as follows, including driver one-click order acceptance, driver order screening, and driver order selection; The driver accepts the order with one click. The order acceptance system automatically returns an order for the driver to accept after screening based on the driver's location and order acceptance conditions. Driver order screening: If the driver uses the one-click order acceptance function, the order acceptance system will screen and return multiple orders for the driver to choose based on the driver's location and order acceptance conditions; The driver selects the order to be accepted. The driver selects the order from multiple orders based on the distance and electricity conditions of the filtered orders.

[0008] Preferably, the functions of the order release module are as follows, including order release and order update; Order release, the order-taking system supports adding orders, modifying orders, pausing orders, and deleting orders; Order update: After the order is released, the content and status of the order can be updated in real time, including the remaining time of the order and the remaining power of the order.

[0009] Preferably, the discharge module is divided into driver arrival, verification code, code scanning, code scanning result, order release start, and order end; When the driver arrives, the background monitors the discharge current and voltage in real time to determine whether the driver has arrived at the designated location. If the driver has not arrived at the designated location, a text message reminder will be sent; Verification code: the order-taking system uses SMS service to send a verification code SMS to the customer and wait for the customer's confirmation; Scan the QR code. The driver pays by scanning the QR code, which is then sent to the order-taking system, and the driver waits for the verification code from the order-taking system to be returned for confirmation. Scanning result: after the scanning is successful, a text message is sent to the customer, who is required to enter a verification code. The driver obtains the verification code entered by the customer and sends it to the order receiving system. The order receiving system verifies the verification code and starts discharging after the verification is passed. Start placing an order.

After completing the form, the order will be published; The electric car driver logs into the order-taking system and selects the order to be accepted based on the distance and electricity conditions of the filtered order; After the electric car driver drives the electric car to the designated point, he uses the discharge gun provided by the power grid to reversely supply power to the power grid according to the order requirements. After the driver arrives at the designated location to perform the discharge operation, he needs to contact the customer to obtain the corresponding verification code. The order can be executed only after the verification code is verified; After the electric car driver completes the discharge task as required, he can click to end the order. The background will calculate the order fee based on the discharge time and discharge amount. After the order is completed, the customer pays for the order, which means that the order is completed.

The method for discharging an electric vehicle upon receiving an order as claimed in claim 6, characterized in that the method further comprises a billing process, an electricity fee settlement process and a cancellation compensation process; The billing process is as follows: according to the content of the order, the billing unit is set. Each charging pile will calculate the power according to the billing unit, and calculate the order fee in segments according to the time period and electricity price of the order. The fee information is sent to the order receiving platform and displayed on the client interface. After the driver confirms the order, the order fee cannot be modified; The electricity fee settlement process is as follows: after the user pays successfully, the order is completed; if the user fails to pay, if the driver has executed the order but has not completed it, the driver will be compensated to complete the order, and the corresponding proportion will be returned to the driver according to the order completion status; The cancellation compensation process is as follows: including user cancellation and driver cancellation; User cancellation: when the driver arrives at the designated location and is ready to start the discharge operation, the customer cancels the order and the cancellation compensation amount is sent to the driver; driver cancellation: if the driver fails to arrive at the designated location within the time limit or does not start the discharge operation within the time limit, the order will be invalid, the system will generate a new order, and randomly assign a driver to take the order, and the deposit in the original driver's account will be deducted. The advantages of the present invention are: Through the two-way energy exchange between electric vehicles and the power grid (V2G technology), this system can effectively release the excess power in the electric vehicle battery during the peak period of the power grid, help the power grid to relieve the power supply pressure, and achieve flexible adjustment of supply and demand. This not only helps to reduce the risk of regional power outages caused by excessive load, but also improves the stability and reliability of the power grid.

[0013] As mobile energy storage devices, the energy in the batteries of electric vehicles is usually idle when not in use. This system enables the reuse of this idle energy by encouraging electric vehicles to discharge to the grid at appropriate times, thereby improving the overall efficiency of energy utilization.

[0014] Through the discharge capacity of electric vehicles, this system can provide fast-response power support to the power grid, quickly injecting power into the grid in emergencies (such as power outages or power shortages caused by extreme weather), and improving the power system's resilience and response capabilities.
