In this embodiment, the charging management device 10 obtains the estimated remaining power of the electric vehicle based on the real-time remaining power and the estimated power consumption obtained from vehicle data when the electric vehicle enters the station. Further, the charging management device 10 subtracts the estimated power consumption from the current remaining power to obtain the estimated remaining power of the electric vehicle.

Step S413: Perform charging sorting based on the estimated remaining power of the electric vehicle. In this embodiment, the charging management device 10 uses the estimated remaining power to determine whether the current remaining power of the electric vehicle is sufficient to provide the estimated power consumption required for the next shift, and at the same time, multiple electric vehicles enter the station to prepare for charging. At that time, the electric vehicles are sorted according to the estimated remaining power of each electric vehicle to obtain the charging order information of the electric vehicle. The smaller the estimated remaining power has a higher priority in sorting. Since it is expected that the smaller the residual power is, the more urgent the charging demand of the electric vehicle is. Therefore, through charging sequencing, the charging management device 10 can quickly arrange charging according to the charging demand.

For example, when the rest time of the electric vehicle is less than a preset rest time, the electric vehicle is not eligible for charging. In one embodiment, the preset rest time is, for example, 1 hour, and the application is not limited thereto. This can prevent the electric vehicle from charging in too short a time, which not only results in poor charging efficiency, but also occupies the charging parking space, resulting in a reduction in the overall charging efficiency of the charging station 3.

Step S417, determine the charging mode. In this embodiment, the charging management device 10 determines whether the electric vehicle is to be charged in the normal mode or the automatic mode based on the number of electric vehicles in the charging station 3 .

In one embodiment, when a power When the electric vehicle completes charging and releases a charging parking space 32, the charging management device 10 allocates charging parking spaces 32 to the electric vehicle based on the charging sequence information. In one embodiment, when the charging management device 10 determines that the charging parking space 32 can be arranged for the electric vehicle based on the charging sequence information, the charging management device 10 further determines based on the available parking spaces, the remaining power of the charging pile 30 and the charging power of the electric vehicle. 32 charging parking spaces are allocated according to the value, so that the electric vehicle can be charged with the corresponding rechargeable power value. For example, assuming that the charging pile 30 is equipped with two charging guns and corresponds to two charging parking spaces 32, when the charging pile 30 is charging an electric vehicle and the remaining power is 30 kilowatts, the charging management device 10 can Another charging parking space 32 of this charging pile 30 is allocated to electric vehicles with a rechargeable power value of 25 kilowatts, so that the same charging pile 30 can charge multiple electric vehicles with no more than the maximum charging power, effectively improving the charging pile 30 The usage efficiency improves the charging efficiency of charging station 3.
