Embodiment
The visual testing method of battery pack system provided by the invention, is provided with proving installation as shown in Figure 1, comprises: the BMS system of mesuring battary group system, hardware interface card, transceiver, host computer.Wherein, described host computer is mounted with CAN bus development instrument, and message information and the measured value etc. of visual testing interface to show that BMS system reports can be provided.
Described BMS system (batteries management system), possesses and communicates by letter with battery pack system, charging/discharging apparatus and carry out the function of high pressure break-make control, specifically comprises the functions such as communication, high input voltage break-make, High voltage output break-make, electric current and voltage sampling.
Described hardware interface card, by the BMS system physical connection of test wire harness and mesuring battary group system, also, by transceiver and host computer physical connection, carries out the transmission of data message.
The CAN bus development instrument that described host computer loads, for example CANalyzer bus development software, can be based on virtual panel (Panel), CAPL(CAN bus access programming language), control editting function, make visual testing interface and realize the visual demonstration to message information, test data.
; described CANalyzer bus development software is programmed by CAPL function; the project that BMS system need to be tested and corresponding CAN message are made into control; and BMS message information and measured value etc. are carried out to visual demonstration on virtual panel Panel by control; finally be solidified into configuration file, convenient test and data recording.
Described bus development instrument also further possesses bus data and transmits (tracking) list, shows that statistics, recorded message that the data content of special packet, interactive statistics, bus load and the bus that sends predefined message, message are disturbed are used for the functions such as playback or off-line assessment.
Below, taking a certain signal as example, by describing step in detail, the present invention is further elaborated.In the present invention, make corresponding control according to the message information that needs to read in system testing process, the characteristic of configuration message information, realizes the visual demonstration to message information.
The current signal reporting taking BMS system in this example, as example describes, comprises the steps:
S11, enter the interface of CANalyzer bus development software Vector Canlyzer/pro;
S12, select above-mentioned interface file (File), open interface editing device (Open Panel Designer), add virtual panel and also enter vector panel designs (Vector Panel Designer) interface; This interface can called after Panel 1, as shown in Figure 2, has the respective regions of workspace 100, object window 200, control window 300, control property 400.
S13, on above-mentioned Panel 1 interface by the view (View) of menu bar, by tool box (Toolbox) add control;
S14, in the drop-down list of Toolbox, add the input and output dialogues frames (Input/Output Box) of virtual panel, configure as required the characteristic (Properties) of this current signal;
S15, in the Properties of step S14, configure this characteristics of signals, by selecting signal in the signal filter (Symbol Filter) of Properties drop-down list Symbol.Signal filter can be selected two kinds of signals, the signal (signer) that system variable (system) and message report, because this signal is the signal that message reports, therefore in the drop-down list of signal filter, select signer, select the signal name corresponding with current signal: BMSPackCurrentHSC1 in message.
S16, in the Properties of step S14, describe the description (Description) under (Appearance Description) drop-down list by outward appearance, signal name can be changed to as required to readability word.For example, the signal name that message reports is BMSPackCurrentHSC1, now can change to readability word: " reporting electric current " 501.
S17, at the drop-down list of Toolbox described in step 14, by adding static text (Static Text), in the drop-down list of its Properties, change its content of text.In this example, can change to the unit that reports electric current, as " A " 502, the line item of going forward side by side.
After above-mentioned steps S11 ~ S17, operation Vector Canlyzer/pro software just can be presented at real-time message information on visual testing interface by corresponding control, convenient monitoring, tester is without familiar professional message signals title, simple to operate.
Data that variable inputs with keyboard or other modes can also be set in the present invention or by corresponding to the result obtaining after input data operation, make and the corresponding control of test data according to variable, on test interface, carrying out visual demonstration.
For example, on the basis of BMSPackCurrentHSC1 signal mentioned above, record the current value that reports of BMS system, carry out the making of current precision test control, suppose that current precision is the number percent that reports difference and the actual current value of current value and actual current value.Specifically comprise the steps:
S21, State selective measurements setting in the View drop-down list at above-mentioned steps S11 interface (Measurement Setup), right button inserts programming node (Insert Program Node), can separately deposit as required, as: PHEV test interface .can, enters CAPL Browser(CAPL and browses) interface.
S22, in the system variable (System variables) of configuration (Configuration) drop-down menu of Vector Canlyzer/pro software, according to project demands, data type of a variable is set, and name variable.
In this example, add 3 system variables, report current value, actual current value, current precision in order to characterize.In this example, report current value, actual current value, current precision is define system variable float curA respectively, float curB, float curC.
S23, in the CAPL of above-mentioned steps S21 Browser interface, definition local variable float CURA, float CURB, float CURC.Variable CURA is the current value that reports of above-mentioned steps S17 record; Variable CURB is the actual current value of battery pack system, can test the line item of going forward side by side by reometer.These two variablees can be inputted by keyboard, can be also to obtain by modes such as external system importings in other example.Variable CURC is by the current precision obtaining after algorithm process, is defined as the difference of variable CURA and variable CURB and the number percent of variable CURB, and this variable CURC is transferred to foreground by system variable curC.The part programming code of CAPL Browser interface and above-mentioned algorithm as shown in Figure 3.
S24, in Panel interface manufacturing system variable curA, float curB, the control that float curC is corresponding, the signal filter (Symbol Filter) of configuration Properties drop-down list Symbol, because this signal is not the signal that message reports, but therefore the variable arranging in programming selects system variable (System variable), and selects corresponding system variable in the drop-down list of signal filter.
After carrying out above-mentioned steps S21 ~ S24, input in real time the electric current value of reporting and the measured value of battery pack system by keyboard, just can show in real time the result of calculation of current precision.
In sum, according to similar method, can will in battery pack system test process, need the reporting information and the test data that show to make respectively corresponding control, taking a certain project as example, control panel as shown in Figure 4.Be illustrated in figure 5 and produce a certain actual test interface of line, malfunction can also be represented with different color lump 602, shown in green expression non-fault, readable extremely strong.Therefore,, by test interface of the present invention, without the professional message signal name of memory, testing efficiency is high, quality is high.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.Read after foregoing those skilled in the art, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
