Charging module switching test system

Technical Field

The utility model relates to a fill electric pile technical field, in particular to fill electric pile's module of charging switches test system.

Background

At present stage 400KW direct current fills electric pile has two host computers and four rifle that charges, a host computer corresponds two rifle that charges respectively, and there are 10 modules that charge in every host computer, fill electric pile in order to improve the output of single rifle that charges, the module function of switching over each other that charges between the host computer has newly increased, that is to say when the output of a host computer can not satisfy the demand voltage and the demand current of one or two rifle that charge that it controlled, can borrow the module that charges to another host computer as required.

At the present stage, the direct current charging pile module is switched to test mainly through a serial port printing mode, or auxiliary testing tools such as a universal meter and a CAN card are utilized. After the test operation, it is necessary to observe a certain phenomenon to obtain test data, and then analyze which charging modules are occupied and which gun is switched to.

The charging module at the present stage is switched to a testing mode, the testing phenomenon can be analyzed after data are obtained, the testing time is long, the observed testing phenomenon is not visual enough, and the operation is complex. And adopt CAN card and serial ports to print to the high-power electric pile that fills of 400KW, also not safe enough to the tester. In addition, for the test of the function of switching the charging module, different test conditions need to be set, the test is repeated, and the efficiency is low by adopting the current test mode.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The embodiment of the utility model provides a module of charging switches test System, as shown in fig. 1, this System is including filling electric pile 1, the BMS (Battery Management System) simulator 2 that is used for simulating the Battery demand, the module of charging 3 that is used for generating module data and be used for the service terminal 4 of display module state, BMS simulator 2 is connected fill electric pile 1, the module of charging 3 is connected fill electric pile 1 connect service terminal 4.

Fill electric pile 1 including charging the rifle and embedded computer, when the module switching test that charges, fill electric pile 1 in a rifle that charges and BMS simulator 2 link to each other to set up the demand voltage and the demand current of BMS simulator 2, after the start-up charges, charge module 3 and charge for this BMS simulator 2. The charging module 3 generates module data in the process of charging the BMS simulator 2, and transmits the module data to the embedded computer in the charging pile 1. The charging module 3 generates module data including the output voltage and the output current of its own module. After receiving the module data, the embedded computer sends the module data and the current occupation state of the charging gun (the charging module occupied by the charging gun) to the service terminal 4. And the service terminal 4 analyzes the module data and displays the module data and the current occupation state of the charging gun through a display.

In a specific implementation, the charging pile 1 may be connected to the service terminal 4 through the router 5, that is, the charging pile 1 and the service terminal 4 communicate with each other through the router 5. Fill electric pile 1 and can send the module data and the current occupation state of rifle that charges to service terminal 4 through router 5, service terminal 4 also can fill electric pile 1 control information through router 5 to realize filling the remote control of electric pile 1. The control information includes charging electric quantity setting information, charging start information, and charging stop information. The service terminal 4 may include a computer and a wireless terminal.

When the charging module switching test is performed, it is not desirable that the setting of the required current value for the BMS simulator 2 is excessively large at first and is smaller than the rated current value of each known charging module 3, and then the charging power amount is set through the service terminal 4 and the charging is started by clicking. During the charging of the BMS simulator 2, the output voltage and the output current of each charging module 3 displayed by the service terminal 4 are observed, as well as the current gun occupancy state. Then, the required voltage value of the BMS simulator 2 is maintained, the required current value is set from low to high, and the state of switching in of the charging module 3 displayed on the service terminal 4 and the like are observed every time a required current value is reset. Especially when the required current setting value reaches the situation that the charging module 3 in the host corresponding to the charging gun cannot meet the requirement, whether the charging module 3 of another host is cut in or not is observed, the setting of the required current is continuously increased, and whether more charging modules 3 of another host are cut in or not is observed. Then, the required current value of the BMS simulator 2 is set from high to low, and the phenomenon observed from the service terminal 4 in the charging process is that the charging module 3 in another host is switched out firstly. When the required current setting reaches that the charging module 3 in the host corresponding to the charging gun can meet the requirement, whether the charging module 3 in the borrowed host is completely cut out is observed. And continuously reducing the setting of the required current, and observing whether the charging module 3 in the host corresponding to the charging gun is cut off continuously. The embodiment of the utility model provides a through the data that observe 4 demonstration of service terminal to whether the module that detects to charge can accurately switch according to the power demand, so relatively more directly perceived.

The embodiment of the utility model provides an use service terminal and BMS simulator auxiliary test instrument, can make to fill electric pile when doing the module switching test that charges, promote efficiency of software testing greatly, the test result is also very accurate, directly perceived moreover, has reduced tester's work load, has also avoided tester to obtain data from filling electric pile communication bus simultaneously, makes test work safer.
