Detailed description of the invention
Vehicular charging method, system and the charging pile below in conjunction with the accompanying drawings embodiment of the present invention provided
It is described in detail.
Embodiment one
The schematic flow sheet of a kind of Vehicular charging method that Fig. 1 provides for the embodiment of the present invention one, this
The method that embodiment is provided can be performed by charging device, such as charging pile, as it is shown in figure 1,
Including:
Step 101, stochastic generation random code.
Wherein, the data volume of random code is more than or equal to 4 bytes.
Concrete, one random code of charging device stochastic generation, it is preferred that the data of this random code
Amount is more than or equal to 4 bytes, and this is owing to this random code will utilize security algorithm to enter as seed
Row calculates, it is thus achieved that key, therefore, the data volume of this random code is the least, is the most easily cracked, instead
It, the data volume of random code is the biggest, then security is the strongest, it is not easy to be cracked.
Random code is calculated by the first security algorithm that step 102, utilization prestore, it is thus achieved that first is close
Key.
Concrete, charging device has prestored a kind of security algorithm, utilize this security algorithm to
Machine code calculates, it is thus achieved that the first key.The security algorithm that charging device is prestored is for carrying out
Identification, concrete principle is as follows: charging device prestores while security algorithm, and this charging fills
Put in be suitable for vehicle, specifically also can be able to prestore same in the battery management system of vehicle
Kind of security algorithm, thus, in charging process, if the security algorithm that prestored of charging device and car
The security algorithm that prestored of battery management system consistent, then carry out random code calculating being obtained
Key also would is that consistent, may determine that the car whether this vehicle is suitable for by charging device accordingly
?.
Step 103, to vehicle to be charged send random code.
Concrete, charging device be by Controller Area Network BUS (Controller Area Network,
CAN) bus treats what charging vehicle was charged, in the present embodiment, and can be total by this CAN
Alignment vehicle to be charged sends random code.
The second key that step 104, reception vehicle send.
Wherein, this second key be described vehicle utilize the second security algorithm of prestoring to described at random
Code carries out calculating acquisition.
Concrete, charging device is after vehicle to be charged sends random code, and vehicle to be charged utilizes
This random code is calculated by its second security algorithm prestored, thus obtains the second key, and then
Vehicle to be charged sends this second key by CAN to charging device.
Step 105, compare the first key and the second key is the most identical, if the first key and described
Two keys are identical, then confirm that authentication is passed through, treat charging vehicle and be charged.
Concrete, if this vehicle to be charged belongs to the scope that charging device is suitable for, then charging device
The second security algorithm that the first security algorithm prestored and vehicle to be charged are prestored is identical,
Then both carry out calculating the first key obtained respectively to same random code and the second key also should

Random code, and this random code carries out by the second security algorithm utilizing vehicle to be charged self to be prestored
Calculate, thus obtain the second key.
Step 208, vehicle to be charged carry this second key by CAN to charging pile transmission
Authentication response.
Step 209, charging pile receive this authentication response, compare the first key and the second key whether phase
With, if identical, perform step 210, otherwise, perform step 211.
Step 210, charging pile are treated after charging vehicle is charged parameter configuration, treat charging vehicle
It is charged.
Concrete, charging pile obtains charge parameter from vehicle to be charged, such as: charge power, fill
Electricity current value and magnitude of voltage etc., and charge power supply is configured, and then, utilize filling after configuration
Electricity power supply is treated charging vehicle by CAN and is charged.
The display of step 211, charging pile is charged unsuccessfully.
Concrete, charging pile utilizes the display display of self to charge unsuccessfully, and then, it is also possible to aobvious
Show that failure cause is authentication failure.
