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.
