Embodiment
As shown in figure 1, first embodiment of the invention provides a kind of charging electric vehicle needing forecasting method, it includes as follows
Multiple steps.
Step S10, the battery electric quantity of each electric automobile in monitored area, estimated down time are determined respectively and current
The probability that time is charged.
Specifically, first, traveling or parked, all registered electric automobiles in monitored area are monitored, obtained
Take the battery electric quantity of each electric automobile, estimated down time；Then, determine each electric automobile in current time according to historical data
The probability charged.
Wherein, battery electric quantity can be characterized using SOC parameter, it is contemplated that down time can be counted according to historical data
Analyze and obtain, can also voluntarily be provided by user.For any electric automobile, historgraphic data recording, for example, history
Upper certain day electric automobile in monitored area the down time of each service point, whether the information such as charge., can according to historical data
To calculate the probability for determining that electric automobile is charged in current time.
Step S12, the charge requirement probability for calculating each electric automobile, and be ranked up to form the row of potential Rechargeable vehicle
Table.
Specifically, in step S12, the charge requirement probability of each electric automobile in monitor area is calculated respectively, and it is right
The charge requirement probability of each electric automobile carries out descending sort to form the list of potential Rechargeable vehicle.
