8 yuan of degree electricity.Furthermore it is also possible to take basic expense+by electricity charge isotype.Standardized payment can be pre-set, and can be with
Adjust at any time.
Match system can be bidded to facilitate pairing using such as stock match system etc.It can also use and such as drip
Drop is called a taxi, the mode of Divine Land express etc software, to facilitate pairing.Advantageously for having a mind to car or treat as power supply
The vehicle of charging vehicle, 3-10 preferable selections are displayed to automatically.
It is understood that parking can also be used to be waved the sides that such as routinely call a taxi such as signal to vehicular traffic in roadside
Formula is matched.It may further specify that unified charging expenses standard.
Preferably, the pairing step S1 further comprises：Determine charging of first electric car 10 to the second electric car 20
Amount.Further, it is determined that charging concluded price and/or completion reimbursement of expense.
Connection Step S2：By the first electrokinetic cell 11 of the first electric car 10 and the second electrokinetic cell of the second electric car 20
21 pass through the charging connections of HVDC 30.
HVDC 30 is direct current high tension transmission device.Preferably there is adjustable transformer ratio.Thus, it is possible to first is moved
The output voltage (such as 420V) of power battery 11 becomes the charge requirement voltage for the second electrokinetic cell 21 for being pressed into the second electric car 20
(such as 450V).It should further be appreciated that HVDC 30 is with current limit circuit and/or current stabilization circuit, to limit charging current and charging work(
Rate.
In the embodiment shown in Figure 2, HVDC 30 is arranged on first electric car 10, with charging wire 41 by HVDC
30 output end is connected with the second electrokinetic cell 21 (preferably fast charge charge port) of car to be charged.Wherein, HVDC 30 input
It is connected with the first electrokinetic cell 11 of car of powering.But the invention is not restricted to this, for example, HVDC 30 can also be arranged on the second electricity
On motor-car 20.The charging delivery outlet of first electric car 10 and the HVDC 30 being arranged on the second electric car 20 input are connected
Connect；And HVDC 30 is connected with the second electrokinetic cell.
As shown in Fig. 2 the first BMS 12 and the second electric car 20 of first electric car 10 are connected with the CAN 42 that charges
2nd BMS 22.So as to realize the first BMS 12 and the 2nd BMS 22 communication.
Preferably, the CAN 42 that charges is integrated into single line beam with charging wire 41.It is but each at the both ends of the integrated line
With two plugs, one is power Transmission plug, and another is that signal conveys plug, and two plugs have different grafting
Form.
In figure, charging wire 41 and charging CAN 42 are shown with single line.But it is understood that charging wire
41 and charging CAN 42 in actual wire quantity more than 1, for example, 2 or 3.
In the embodiment shown in Figure 2, HVDC 30 transformer ratio is controlled by the first BMS 12.It is understood that
Can there are the 2nd BMS 12 or other control units to control HVDC 30 transformer ratio.So that the first electrokinetic cell 11
Output voltage be matched with the required input voltage of the second electrokinetic cell 21.As it was previously stated, more advantageously so that the first power
The output voltage of battery 11 is matched with the fast charge pattern of the second electrokinetic cell 21.It is pointed out that the first electrokinetic cell 11
Output voltage is DC voltage.
In a preferred embodiment, in Connection Step S2, the first electrokinetic cell 11 passes through with the second electrokinetic cell 21
The mutual charging connection of non-contact charge mode.That is, the first electrokinetic cell 11 is electrically connected with vehicle-mounted electric energy wireless output unit
Connect, and to power supply；And the second electrokinetic cell 21 is wirelessly input to unit spot with vehicle-mounted electric energy and is connected, and receive from it electric energy.
In this case, charging wire 41 can be saved.Further, charging CAN 42 is saved, passes through the first electric car 10 and the second electricity
The wireless telecommunications connection of motor-car 20, to realize the first BMS and the 2nd BMS communication.
It is highly preferred that on the basis of a upper preferred embodiment, in the first electric car 10 and the second electric car 20 to close on
In the state of mode travels together, charged.That is, in the pairing stage, that is, consider the first electric car 10 and the second electricity
The estimated stroke of motor-car 20, and charging modes are planned.
Communicating step S3：The status information of the first electrokinetic cell 11 and the second electrokinetic cell 12 is obtained, and judges the first electricity
Whether motor-car 10 can charge to the second electric car 20, if otherwise going to S4；If it is S5 is gone to.
That is, whether have in the connection of two cars and then secondary the first electrokinetic cell 11 for confirming the first electric car 10
Enough electricity provide the charge volume determined to the second electrokinetic cell 12.If it can, then charged.If it is not, enter
Row alarm.Charge volume is adjusted, or re-starts pairing.
It may also be noted that " judging whether the first electric car 10 can charge to the second electric car 20 " also includes first
Whether the electrokinetic cell 12 of electrokinetic cell 11 and second is in normal chargeable state.If abnormal state, it is impossible to charged,
Also alarmed.If for example, the temperature anomaly of the first electrokinetic cell, this is alarmed.
In a preferred embodiment, in communicating step S3, the first BMS and the second electric car 20 of the first electric car 10
The 2nd BMS communication, according to the supply voltage of the first electrokinetic cell, SOC；The charging voltage of second electrokinetic cell, SOC；And
HDVC transformation scope, to judge whether the first electric car 10 can charge to the second electric car 20.Advantageously, by first
BMS is judged.It can also be judged by external server or system.
Alarming step S4：Alarm signal is sent, and carries out troubleshooting.For failure or the concrete condition of alarm, carry out
Troubleshooting.For example, if the first electrokinetic cell current electric quantity is not enough to provide the charge volume determined during initial pairing, again
Charge volume is determined, or terminates this charging.The concrete form of alarm signal can be sound and light alarm signal, can also be vehicle-mounted aobvious
Show and shown on device or associate device (such as mobile phone equipped with specific APP).
Pressure regulation step S5：HVDC 30 transformer ratio is adjusted, by the output of the first electrokinetic cell 11 of the first electric car 10
Voltage becomes to be depressed into and can be used in charging to the second electrokinetic cell 21.
Advantageously, use can carry out the charging voltage of quick charge.
Charge step S6：Charging circuit is connected, the second electrokinetic cell 21 is charged.
Preferably, in charge step S6：Close the first electrokinetic cell 11 negative pole relay and charge relay or
Positive pole relay；The negative pole relay and charge relay of the second electrokinetic cell 11 are closed, the second electrokinetic cell 21 is carried out
Charging.
Preferably, in the charge step S6, detect whether to have completed the charge volume；And first electrokinetic cell 11
Electricity whether be less than setting value, if any one in two judged results is yes, stop charging.The setting value is for example
Can be 20%SOC, or can be according to stroke.Advantageously, after completing charging, mutually given and commented with charging side by supplier of electricity
Valency.
The mutual charging method of electric car provided by the invention, by way of electric car mutually fills, overcomes to a certain extent
The shortcomings that infrastructure insufficiencies such as charging pile.It may advantageously facilitate the development of electric car.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
