" starting to charge up " button, now, the power on of electromagnet, electromagnet produce magnetic field, due to electromagnet power supply for exchange
Electricity, therefore caused magnetic field is continually changing, is also constantly changed by the magnetic flux of charger inductance coil 4 so that inductance
Coil 4 produces electric current, and the electric current is converted into the electric energy that electric automobile can use after flowing through charger body 3 and stored.
After charging complete, " stopping charging " button on charging pile controller 2 is pressed, electromagnet and straight-line motion mechanism are stopped.
Embodiment two：Present embodiment is wireless to the electric automobile based on electromagnetic force described in embodiment one
The further restriction of charging pile, in present embodiment, described charging inlet 1 also includes wireless receiving module, described wirelessly to connect
Module is received to be used to receive energy data and the charge threshold that electric automobile is sent, and by the energy data and charge threshold send to
Charging pile controller 2, charging pile controller 2 are embedded in Power control module, and Power control module is used to judge that electric automobile is sent out
Whether the energy data come reaches threshold value, and stops charging when reaching threshold value.
In present embodiment, charging pile controller 2 is embedded in the Power control module realized by software, inside electric automobile
It is provided with wireless transmitter module.Charge threshold should be less than or can be stored equal to electric automobile the upper limit of electric energy.After charging starts,
Wireless transmitter module constantly sends the real-time energy data that charge threshold and electric automobile store, charging pile controller 2
Data are constantly received, and constantly the energy data received compares with charge threshold, when the energy data received reaches

Time be also different, it is necessary in summary various factors each charging pile and charging inlet 1 are carried out it is integrated ordered.Charging knot
Beam time Estimate value adds charging interval estimate equal to the time started to charge up, and ordering rule was estimated according to the charging end time
Evaluation sorts from small to large, if the charging end time estimate of wherein certain several charging inlet 1 is equal, these chargings
Interface 1 sorts from the near to the remote according to distance.Such as the charging pile of red mark has two：No. 1 charging pile and No. 2 charging piles, No. 1
The charging end time estimate of No. 1 interface of charging pile is 8 hours, and the charging end time of No. 2 interfaces of No. 1 charging pile is estimated
Evaluation is 7 hours, and the charging end time estimate of No. 1 interface of No. 2 charging piles is 7 hours, No. 2 interfaces of No. 2 charging piles
Charging end time estimate be 9 hours, then be ordered as：
1. No. 2 interfaces of No. 1 charging pile；
2. No. 1 interface of No. 2 charging piles；
3. No. 1 interface of No. 1 charging pile；
4. No. 2 interfaces of No. 2 charging piles.
While ranking results are shown, can also show each charging inlet 1 reach the time, time that needs wait with
And it is expected that complete the time (i.e. charging interval estimate) of charging.
Confirmation receiving unit can also be increased, after subscription information has been sent, receive the charging pile of subscription information
Confirmation can be beamed back, represents that this received subscription information of the charging pile, electric automobile represent pre- after receiving confirmation
Success is ordered, can avoid whether subscribing successfully because user is uncertain and subscribe multiple charging piles or charging inlet simultaneously, cause to provide
Source wastes.
