and planning a travel route of the electric automobile in an electronic map.
And detecting the residual electric quantity of the rechargeable battery of the electric automobile.
And displaying the distance capable of driving of the electric automobile and at least one charging station within the range of the distance capable of driving in the electronic map according to the residual capacity of the rechargeable battery of the electric automobile and the power consumption speed of the rechargeable battery of the electric automobile.
According to the residual capacity and the power consumption speed of the rechargeable battery, the time for which the rechargeable battery can continuously work can be calculated, and then the time for which the rechargeable battery can continuously work is multiplied by the driving speed of the electric vehicle, so that the distance capable of driving of the electric vehicle can be determined, and further the charging station in the distance capable of driving can be determined.
Acquiring the state of a charging device in any charging station within the travelable distance range; aiming at the charging devices in the use state, acquiring the remaining time of each charging device for completing the current charging task, determining the running time of the electric vehicle reaching the charging station according to the distance from the electric vehicle to the charging station and the current running speed of the electric vehicle, sequencing and displaying each charging device in the charging station according to the sequence of less to more remaining time for completing the current charging task in the electronic map, and simultaneously displaying the comparison result of the remaining time for completing the current charging task of each charging device and the running time of the electric vehicle reaching the charging station; and for the charging devices in the unused state, displaying the number of the charging devices in the unused state in the electronic map.
Further acquiring the state of the charging device in the charging station. And aiming at the charging devices in the use state, sequencing and displaying all the charging devices in the charging station according to the sequence of less to more residual time for completing the current charging task in an electronic map, and simultaneously displaying the comparison result of the residual time for completing the current charging task of all the charging devices and the running time of the electric vehicle reaching the charging station. The number of charging devices in an unused state is also shown.
For example, there are two charging stations within the user's currently travelable distance range. For the closer charging stations, all charging devices are in use, i.e. all charging devices are performing charging tasks, and for the farther charging stations, there are charging devices that are not in use. The remaining time for the charging devices of the two charging stations to complete the current charging task is counted and then compared with the travel time of the user driving the electric vehicle to the respective charging station. If the remaining time of the charging device for completing the current charging task in the closer charging station is about the same as the traveling time of the electric vehicle to the corresponding charging station, that is, if the user arrives at the charging station and the charging device completes the charging task, the user can charge without queuing basically, and the user may select the charging station for charging. Of course, the user may also select a charging station in which a charging device is present in an unused state.
In this case, the user can know which charging stations can be charged, and can also know the actual conditions in each charging station, which helps the user to more comprehensively and accurately know the information of the charging stations in the process of driving, and helps to improve the operating efficiency of the electric vehicle.
In a preferred embodiment, the method for managing charging of an electric vehicle further includes: determining the estimated value of the residual electric quantity of the rechargeable battery when the electric vehicle arrives at each charging station according to the residual electric quantity of the rechargeable battery of the electric vehicle and the power consumption speed of the rechargeable battery of the electric vehicle, and determining the time consumed for charging the rechargeable battery of the electric vehicle when the electric vehicle arrives at each charging station according to the estimated value of the residual electric quantity of the rechargeable battery when the electric vehicle arrives at each charging station.
The time required by the electric vehicle to reach each charging station can be calculated by combining the distance from the current position of the electric vehicle to each charging station and the driving speed of the electric vehicle, and then the estimated value of the residual electric quantity of the rechargeable battery when the electric vehicle reaches each charging station can be calculated according to the residual electric quantity and the power consumption speed of the rechargeable battery. Since the charging speed of the rechargeable battery is usually fixed, the time required for the electric vehicle to complete charging at each charging station can be further determined based on the estimated value of the remaining capacity of the charging station when the electric vehicle arrives at each charging station. This time may be used as a reference for the user to make a more appropriate decision on which charging station to charge. For example, when a charging station is closer, the charging time is relatively shorter because less electricity is consumed when the charging station is reached; while charging at a distant charging station, the time required to complete the charging is greater due to the greater amount of electricity consumed in the course of travel, but for a distant charging station, the user can just rest there, so based on the provided time parameter, the user can make a more appropriate decision.
In a preferred embodiment, in the electric vehicle charging management method, the acquiring the state of the charging device in any charging station within the travelable distance range includes: and acquiring the state of a charging device in the charging station within the travelable distance range according to the selection of the user on any charging station within the travelable distance range on the electronic map.
When the system provides a plurality of charging stations within the range of the driving distance, a user can click one of the charging stations on the user terminal to check the specific use condition of the charging devices in the charging stations, so that the decision on which charging station to charge is made.
The user terminal may be a smartphone.
In a preferred embodiment, the method for managing charging of an electric vehicle further includes: sending a reservation request to one of the charging stations in the range of the travelable distance, and reserving the charging operation of the rechargeable battery of the electric automobile at a reserved time; the charging station reserves a charging device based on the reservation.
The user can also send a reservation request to one of the charging stations through the user terminal, namely, the charging operation is carried out at the reserved time. The charging station can reserve a charging device for the user according to the reservation.
In a preferred embodiment, in the electric vehicle charging management method, after the reservation request is sent to one of the charging stations within the travelable distance range, the reservation for the charging operation of the rechargeable battery of the electric vehicle at a reserved time is made, and when the actual time when the electric vehicle arrives at the charging station and performs the charging operation on the rechargeable battery of the electric vehicle exceeds the reserved time by a set time period, the reservation for the charging operation of the rechargeable battery of the electric vehicle at the charging station is automatically cancelled.
The user provides the reservation request through the user terminal, after the charging operation of the rechargeable battery at a reserved time is reserved, if the time of reaching the charging station exceeds the reserved time by a set time period, the reserved time is automatically cancelled, so that other users can be ensured to normally charge at the charging station, and the waste and improper occupation of charging resources are avoided. For example, the user estimates that the charging station is reached at 1 pm based on the distance from the current location to the charging station, and then reserves to charge at the charging station at 1 pm to save queuing time. But the user has not yet reached the charging station at half 1 pm, the charging station may automatically cancel the reservation. The set time period exceeding the reserved time may be set according to actual conditions, such as 20 minutes or half an hour.
In a preferred embodiment, in the electric vehicle charging management method, after the reservation request is sent to one of the charging stations within the travelable distance range, and the charging operation of the rechargeable battery of the electric vehicle at a reserved time is reserved, when the actual time when the electric vehicle arrives at the charging station and performs the charging operation on the rechargeable battery of the electric vehicle exceeds the reserved time by a set time period and there are other charging devices in an unused state in the charging station in addition to the reserved charging device, the reservation of the charging operation of the rechargeable battery of the electric vehicle is automatically postponed at the charging station.
In another case, when the user does not arrive at the charging station according to the reserved time, but the charging device at the current charging station is still vacant to charge other electric vehicles, the reservation of the user can be reserved and prolonged for a certain period. However, if the number of electric vehicles in the charging station increases and the reserved charging device needs to be put into use, the reservation of the user is automatically canceled at this time, and the reservation of the charging device is released.
In a preferred embodiment, in the electric vehicle charging management method, after the reservation request is sent to one of the charging stations within the travelable distance range, the charging station returns reservation deposit amount information according to the reservation request, a reservation deposit is paid to the charging station based on the reservation deposit amount information, and the charging station completes reservation for the charging operation of the rechargeable battery of the electric vehicle at a reserved time based on the payment information of the reservation deposit.
After a user makes a reservation request to a certain charging station, the charging station returns reservation deposit amount information according to the reservation request, and when the user finishes payment for the reservation deposit through the user terminal, the charging station finishes reservation based on the payment information. If the user charges according to the reserved time, the actual charging fee of the deposit deduction part is reserved. If the user does not charge according to the reserved time and does not cancel in advance, the reserved deposit is not refunded.
While embodiments of the invention have been disclosed above, it is not intended to be limited to the uses set forth in the specification and examples. It can be applied to all kinds of fields suitable for the present invention. Additional modifications will readily occur to those skilled in the art. It is therefore intended that the invention not be limited to the exact details and illustrations described and illustrated herein, but fall within the scope of the appended claims and equivalents thereof.
