In one embodiment, the power supply equipment comprises a fixed charging station and a power-taking vehicle;

Step S206, sending a charging instruction including the charging position and the selected power supply equipment to a selected mobile charging device, wherein the mobile charging device goes to the charging position after getting power from the selected power supply equipment.

Step S207, a charging position is sent to the electric automobile to be charged, when the electric automobile to be charged runs to the charging position, if the mobile charging device is detected to be close to a preset distance range, the mobile charging device is grabbed and butted, and the electric automobile to be charged is charged by the mobile charging device.

Specifically, when a user needs to charge, for example, the electric vehicle capacity decreases to a preset capacity threshold, a charging request is sent to the orchestration electronic device, and step S201 is triggered to respond to the charging request. Then, in step S202, the mobile charging device information, the current position information of the electric vehicle to be charged, and the power supply equipment information are acquired.

In this embodiment, the power supply unit includes fixed charging station, gets the electric vehicle. The mobile charging device may draw electricity from a stationary charging station or from an electricity-drawing vehicle.

The fixed charging station is used as a mother port and a maintenance point of the mobile charging device, and the mobile charging device gets electricity from the fixed charging station without driving a vehicle to charge. After the mobile charging device goes to the fixed charging station, manual power taking or automatic power taking can be performed by the fixed charging station. The fixed charging station can adopt the existing wired charging mode or wireless charging mode to charge the mobile charging device.

The electricity-taking vehicle is a nearby vehicle with surplus electricity. The electricity-taking vehicle can be provided with a grabbing device, and when the mobile charging device approaches, the grabbing device grabs the mobile charging device and charges the mobile charging device. The specific charging mode can adopt the existing wired charging mode or wireless charging mode.

Wherein the power supply device may be a fixed charging station or a nearby powered vehicle. The position of the fixed charging station is a fixed position. The electricity-taking vehicle is a vehicle which is willing to share electric energy near the current position of the electric vehicle to be charged. The position of the vehicle willing to share the electric energy, the allowed electric quantity transfer and the electric quantity transfer cost can be sent to the overall electronic equipment to determine that the vehicle is the electricity-taking vehicle. The electric vehicle may be a vehicle traveling or stationary on a non-transit road, such as a garage or roadside stop vehicle. The electricity-taking vehicle can also be a vehicle running on a traffic road. If the electricity-taking vehicle is a stationary vehicle, the mobile charging device can be notified of the electricity-taking by transmitting its position. If the electricity-getting vehicle is a traveling vehicle, an electricity-getting position is selected on a planned traveling path of the electricity-getting vehicle. Specifically, an electricity-taking position can be selected according to road condition information on a planned driving path of the electricity-taking vehicle. For example, a parking-allowed position, a slow-moving-allowed position, a low-traffic position, and a low-traffic position are selected on the planned travel path of the electricity-taking vehicle.

The next destination may be a fixed charging station, the location of the next powered vehicle, or the charging location of the next electric vehicle to be charged. Because the electric automobile that waits to charge can snatch removal charging device, remove charging device and can travel along with the electric automobile that waits to charge together, consequently, it is not necessarily suitable directly to return the power supply unit who gets the electricity, can acquire near getting the electricity vehicle or other electric automobile that wait to charge, carries out overall planning and distribution, realizes bigger economic benefits.

And finally, respectively calculating the power taking cost of each power taking path. The specific electricity-taking cost calculation formula is as follows:

wherein n is 1, 2, … …, i. Where a1 is a first cost of the mobile charging device moving along the first path, a2 is a second cost of the mobile charging device moving along the second path, a3 is a third cost of the mobile charging device moving along the third path, a4 is a fourth cost of taking electricity from the stationary charging station, a5 is a fifth cost of taking electricity from the electricity-taking vehicle, and a6 is an electricity transfer cost provided by the electricity-taking vehicle. The electric quantity transfer cost is set by the electricity taking vehicle and is sent to the overall electronic equipment, or the overall electronic equipment sets the electric quantity transfer cost in an integrated mode.

In one embodiment, for each power-taking path, first path condition information of a first path, second path condition information of a second path, and third path condition information of a third path are respectively acquired, and if the first path condition information, the second path condition information, or the third path condition information does not satisfy the automatic driving condition, the cost of the path that does not satisfy the automatic driving condition is set to a large value, so that the power-taking path is not selected finally.

In one embodiment, for each power-taking path, first path condition information of a first path, second path condition information of a second path, and third path condition information of a third path are acquired, and if the first path condition information, the second path condition information, or the third path condition information does not satisfy the automatic driving condition, the power-taking path including the power-taking path not satisfying the automatic driving condition is deleted.

In step S205, of all the power-taking paths included in the mobile charging device, the power-taking path with the lowest power-taking cost is selected as the selected power-taking path, the mobile charging device corresponding to the selected power-taking path is used as the selected mobile charging device, and the power supply device corresponding to the selected power-taking path is used as the selected power supply device.

And finally, respectively executing the step S206 and the step S207 to transmit the charging position to the selected mobile charging device or the electric automobile to be charged. The mobile charging device automatically gets electricity from the selected power supply equipment according to the selected electricity getting path, then goes to the charging position and completes charging with the electric vehicle to be charged running to the charging position.

The mobile charging device of the embodiment can be moved between the fixed charging station/charging station and the vehicle to be charged, and can also be moved between the nearby vehicle with surplus electric quantity and the vehicle to be charged. And meanwhile, the power taking paths are subjected to overall analysis according to the power taking cost, the power taking path with the lowest power taking cost is selected, and the decision mode is based on the algorithm logic with the best economy, so that the charging economy is optimal.
