The power vehicle consumes energy, discharging tail gas, pollutant atmosphere; For environmental protection, developed country is most of in the world develops to the electric automobile direction.Along with the development of China's electric automobile, the development of electric motor car charging equipment technology is very fast, and country has also put into effect many relevant standards.Stipulate that wherein the fast charge equipment interface must possess the CAN bus communication simultaneously, and has issued corresponding standard GB/T 27930-2011 etc.Charging system is the brace foundation of ev industry as the energy supply link of electric automobile operation.Reality is automobile vendor, charging equipment manufacturer because the relative standard device of neither one is for referencial use, need expend a large amount of time costs and human cost when this charge port of debugging CAN communication.
Summary of the invention
The purpose of this utility model is exactly that a kind of reliability height, easy to operate charging electric vehicle interface CAN communication test calibration facility are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of charging electric vehicle interface CAN communication test calibration facility, being used for the analog electrical electrical automobile communicates by letter with charging equipment, this calibration facility comprises central controller, storer and the power supply that has the CAN bus interface, described central controller is connected storage and power supply respectively, and described CAN bus interface is connected with charging electric vehicle interface or charging equipment.
Described central controller is digital signal processor or the single-chip microcomputer that is embedded with standard CAN communication protocol.
Described central controller is provided with the WiFi wave point, and this WiFi wave point is connected with handheld device by the WiFi network.
Described handheld device comprises mobile phone or panel computer.
Described central controller is provided with the button of input operation instruction.
This calibration facility also comprises display, and this display is connected with central controller.
Compared with prior art, the utlity model has following advantage:
(1) the utility model carries out the CAN communication check by the central controller and the GB/T 27930-2011 specified standard CAN communication protocol that have the CAN bus interface to charging electric vehicle interface and charging equipment, record non-compliant place, the detecting reliability height;
(2) central controller of the present utility model is provided with the WiFi wave point, can show and operation in handheld device, and is easy to operate, can save the cost of parts such as demonstration and record again;
(3) the utility model can carry out precharge to the charging inlet of electric automobile by power supply analog charge equipment, to guarantee the normal of data communication in the pre-charge process.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is CAN communication check schematic flow sheet of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of charging electric vehicle interface CAN communication test calibration facility, being used for the analog electrical electrical automobile communicates by letter with charging equipment, this calibration facility comprises central controller 1, storer 2 and the power supply 4 that has the CAN bus interface, described central controller 1 is connected storage 2 and power supply 4 respectively, and described CAN bus interface is connected with charging electric vehicle interface or charging equipment.
Wherein, central controller 1 is for being embedded with digital signal processor (DSP) or the single-chip microcomputer (MCU) of GB GB/T 27930-2011 specified standard CAN communication protocol, and the core controller of this equipment is finished the detection control of total system and the simulation of CAN communication.Storer 2 is used for the storage of significant data record and running parameter.
CAN bus interface on the central controller 1 is used for the simulation of charge port communication, and this CAN bus interface can be communicated by letter with charging equipment by the analog electrical electrical automobile, but also analog charge equipment is communicated by letter with electric automobile, with each link of demarcation CAN communication, and makes record.Be both differently in the communication information frame of this calibration facility and electric automobile and electric automobile, but according to GB/T27930-2011 regulation, its workflow is consistent.As shown in Figure 2, its flow process specifically can be described as: after the connector physical connection, successively charge shake hands, the CAN communication process simulation of charge parameter setting, charging simulation and charging terminal procedure wherein, charging process since in the simulation process electric current little, can directly report an error and skip.
Central controller 1 is provided with the WiFi wave point, and this WiFi wave point is connected with handheld device by the WiFi network.The WiFi wave point be used for to solve the transmission record of running parameter and the operation of system, makes the easy to operate, powerful of system, can save again to show and the cost of parts such as record.The WiFi communication standard can adopt one or more among the 802.11a/b/g/n.Handheld device can be used mobile phone or panel computer, and its operating system can be ios, Android or Linux, WinCE etc.
Also be provided with button on the central controller 1, button is used for the input of powering on, cutting off the power supply of equipment and main operational order.
Power supply 4 not only will solve the power supply of native system, also simulated battery pre-charge process at least; So require the ability of output current to reach more than the 0.5A, to guarantee that CAN communication is unlikely to start the back and interrupts at once.Simultaneously, because the voltage of electric automobile power battery is generally higher, scope is bigger, thus this power supply palpus specialized designs, for constant current output, to satisfy the requirement of different electric automobiles.
This calibration facility also can comprise display 3, and this display 3 is connected with central controller 1, is used for the demonstration of key job parameter.
Structure in sum, the utility model use DSP/MCU as central controller, are equipped with data-storing unit, CAN interface, action button and WiFi wave point.Charge port CAN simulated technological process has been solidified by national standard in system, can communicate by letter with charging equipment by the analog electrical electrical automobile, but also analog charge equipment is communicated by letter with electric automobile, with each link of demarcation CAN communication, and makes record.The WiFi interface that possesses, convenient greatly use, and saved cost.Specially designed power supply can the simulated battery pre-charge process, has guaranteed continuing of CAN communication.
The utility model provides the scheme of charge port CAN interface bus test calibration equipment, and the relevant bright and accompanying drawing in detail of saying is provided.All scopes of the present utility model should be as the criterion with following claim scope, and embodiment and the approximate construction of the spirit variation similar with it of all claim scopes all should be contained among the utility model.
