Background
PHEV (Plug-in Hybrid ELECTRIC VEHICLE ) emission test and energy consumption test are mandatory detection items required by regulations, can synchronously develop the test, reduce the test cost and shorten the test period. Emissions are emissions of each contaminant measured by an emissions test system; the energy consumption includes fuel consumption and electricity consumption: the fuel consumption is calculated based on the emission of related pollutants by using a carbon balance method, and a final result is obtained by using weighted calculation; the electricity consumption is obtained by integrating the current and the voltage of all REESS (Rechargeable ELECTRIC ENERGY Storage System) in each test cycle by using a power meter or vehicle-mounted data, and then obtaining the final result by weighting calculation based on the electricity consumption obtained from the outside.
In the test process, each time a test cycle is run, whether a termination judgment condition is met or not is required to be judged, whether the test is effective or whether correction is required to be carried out is required to be judged in the CS electric quantity maintenance mode test process, and as real-time judgment cannot be carried out, each time a test cycle is run, a vehicle is immersed, data are acquired, manual calculation is carried out, and the next cycle test or termination test is continued after the judgment. After the test, the emission data is led out from the emission test system to perform data calculation processing, and the electricity consumption data is led out from the power meter or the vehicle-mounted data to perform data calculation processing.
However, since different operation devices are involved in the test process, the emission test system is generally placed in a device control room, and a power meter or a data acquisition device for acquiring current and voltage data of the vehicle-mounted REESS is placed in a test environment bin, at least 2 testers are required to pay attention to the device conditions during the test, and personnel waste is caused.
In addition, because real-time monitoring, calculation and judgment are needed to be carried out on test process data in the test process, the requirement on test personnel is higher, the possibility of test failure caused by calculation errors is easily caused, meanwhile, the total test duration can be prolonged due to the waiting time of the vehicle dipping caused by calculation and judgment, and the efficiency is low.
Therefore, to meet the testing requirements, a PHEV emission and energy consumption synchronous testing technology is now provided.

firstly, how to monitor and collect the current and voltage data of the vehicle-mounted REESS in real time, calculate the electricity consumption measurement and the pollutant emission, and avoid the test failure caused by the calculation error of human factors:
The data collected by the data collection module is transmitted to the intelligent management module in real time, and the intelligent management module can monitor various data dynamics in real time and calculate required result data (electricity consumption measurement, pollutant emission and the like) according to requirements. Real-time monitoring and calculation can find whether abnormal conditions exist; in addition, because of the electric quantity calculation and the judgment formulas, the pollutant calculation formulas and the like are relatively complex and have large calculated quantity, the intelligent system calculation can avoid the erroneous test ending judgment caused by the calculation errors and judgment errors of people, thereby causing test failure.

It should be noted that the tests according to the embodiments of the present application include a CD stage test, a CS stage test, or a CD stage test and a CS stage test, which are not limited in order, but: the CD stage test and the CS stage test comprise different speed segments including low speed, medium speed, high speed and super high speed.
Currently, research and development for CD/CS staging and control strategies is usually initiated from the FCT testing process. The power consumption cycle (CHARGE DEPLETING CYCLE) refers to a cycle in which the state of charge of the on-board energy storage system is gradually consumed, i.e., a cycle in the CD phase. The state of charge of the vehicle-mounted energy storage system is maintained within a certain tolerance zone and is circulated for a plurality of working condition tests, wherein the circulation is Charge Sustaining Cycle, namely the circulation in the CS stage. The initial state of the CD stage is the initial full SOC of a battery of the plug-in hybrid electric vehicle, and then the energy consumption of the battery of the vehicle is reduced, and the CS stage is entered when the energy consumption is smaller than a certain SOC;
the functions of each module are described using the CD and CS test phases as examples, respectively.
First, the CD test phase power consumption cycle (Charge-DEPLETING CYCLE):
And a data acquisition module: all test equipment are connected, all REESS are connected with a power meter by adopting a current clamp and a voltage clamp to measure current and voltage, the power meter is connected with a test port of a data acquisition module in a networking mode and the like, and the voltage and current sampling frequency of the power meter is set to be 20Hz (if the current clamp or the voltage clamp is inconvenient to install, current or voltage data are required to be acquired through a bus acquisition device by a vehicle-mounted data port, and then the bus acquisition device is connected with the data acquisition module); the emission analyzer is connected with the data acquisition module through a data port.
All the devices enter a ready state, are controlled in a centralized way by a data acquisition module, run a test program based on a test cycle (WLTC), start acquisition by one key at the same time when the test starts, and avoid the problem that the data alignment cannot be ensured due to the difference of the starting test time of the devices.
The data acquisition module acquires all REESS current (A) and voltage (V) data, pollutant emission data, vehicle speed and the like of each circulation working condition (each speed section) in real time, and transmits the data to the intelligent management module for use.
And the intelligent management module is used for: and (3) starting the test, observing, judging or setting index judging data to judge whether the data are abnormal or not according to the real-time electric quantity and the emission data transmitted by the data acquisition module, immediately stopping the test if the data are abnormal, restarting after the reason is eliminated, and calculating CD stage termination judging conditions according to all the acquired data of the test cycle (each speed section) after one test cycle is ended, namely when the relative electric energy variation REECc is smaller than 0.04, and reaching the termination judging conditions.
The corresponding calculation formula is as follows:
Wherein,
Ecycle-cycle energy requirement, which can be calculated according to the test quality and resistance information of the test vehicle, and the unit is Ws;
Delta EREESS, c-c test cycle all REESS changes in electrical energy per unit Wh; (8-9)
G-REESS;
m-REESS total number;
t0 to the start time of the c-th test cycle, in s;
tend-end time of the c-th test cycle, unit s;
u (t) REESS, g, c-c test cycle time range, change to the voltage value of REESS at time t, unit V;
I (t) g, c-c the time frame of the c-th test cycle, the current value at time t, unit A, of REESS of g is changed.
And the intelligent management module judges the termination condition of each test cycle, and when the termination judgment condition is not reached, the intelligent management module continues the next test cycle until the CD test stage is ended when the termination judgment condition is reached.
An intelligent data processing module: after the test is finished, the data acquired in the CD stage are calculated and processed to obtain the test result of the emission and the energy consumption in the CD stage, whether the test result is qualified or not is judged based on the standard requirement corresponding to the relevant regulation, and finally the result or the detection report is output.
Second, CS test phase Charge-Sustaining (state of Charge maintenance):
Before the CS test is performed, the test vehicle should travel for at least one test cycle to complete the pretreatment, and when the above termination determination condition is satisfied, the pretreatment is terminated at the end of the test cycle. Therefore, at the beginning of the preprocessing stage, the data acquisition module is as same as the CD test stage, and needs to connect related equipment and acquire data, and when the intelligent management module judges that the termination judgment condition is reached, the preprocessing is ended;
here, the termination determination condition, that is REECc as mentioned above, is less than 0.04.

The corresponding calculation formula is as follows:
E fuel,CS＝10×HV×FCCS,nb×dCS; wherein,
Delta E REESS,CS -CS the amount of change in electrical energy per unit Wh of test cycle REESS;
e fuel,CS —CS test cycle fuel energy equivalent, unit Wh;
10-unit conversion coefficient;
HV-heating value of fuel, units kWh/L;
FC CS,nb -fuel consumption in units of L/100km for unmodified CS test cycles; can be obtained from emissions data;
d CS -actual driving mileage of CS test cycle, unit km, can be obtained from vehicle speed data.
And (3) immersing: and (3) immersing the vehicle within 12h after the charging is finished, wherein the vehicle is immersed for 12-15 h at (-7+/-3) DEG C under the condition that the vehicle closes all windows, the average ambient temperature is kept within the range of (-7+/-3) DEG C per hour during the immersing of the vehicle, the instantaneous temperature is kept within the range of (-7+/-6) DEG C, and the vehicle cannot be continuously immersed for 3min outside the range of (-7+/-3) DEG C.
If the test result is invalid, carrying out vehicle dipping, and carrying out CS test again after vehicle dipping; if the test result is valid, the next step is carried out, and the test result is corrected and judged: if Δe REESS,CS is negative (i.e. REESS is in discharge) and the cyclic correction standard c is greater than 0.005, the result needs to be corrected, and correction is performed according to the corresponding correction formula in the existing industry standard; in addition, no correction may be performed.
An intelligent data processing module: after the test is finished, the data acquired in the CS stage are calculated and processed (if the test result in the CS stage needs to be corrected, the CO2 and the fuel consumption are corrected according to a correction formula), the test result of the emission and the energy consumption in the CS stage is obtained, whether the test result is qualified or not is judged based on the corresponding standard requirements in the existing industry standard, and finally the result or the detection report is output.
And finally, the intelligent data processing module performs weighting processing and calculation on the data in the CD and CS stages to obtain weighted comprehensive emission, energy consumption results and other result data, judges whether the test result is qualified or not based on standard requirements, and finally outputs the result or a detection report.
