With the large-scale promotion and development of electric vehicles, Electric vehicle test Has gradually highlighted its importance and become more professional. DEWETRON has always been committed to this. It is in the forefront of the market in the electric vehicle testing industry, with users all over the world and praised by users. At present, some domestic automobile enterprises and parts enterprises are still using some schemes in the power system to test electric vehicles, among which power analyzers are mostly used. In order to further understand the advantages and disadvantages of the two in electric vehicle testing, the traditional power analyzer and DEWE2-PA7 power analyzer and DEWE3-PA8 Conduct comprehensive comparison.

The advantages and disadvantages of the traditional power analyzer or other instruments in the test of electric vehicles are compared with those of the DVC power analyzer as follows:

Shortcomings of traditional power analyzer or other instruments:

Ø Use a variety of data acquisition systems (multimeter, power analyzer, CAN recorder, data recorder, video recorder, etc.);

Poor synchronization between multiple instruments;

Ø Data consolidation (data is stored in different systems in different data formats);

Ø Original data cannot be recorded continuously;

Slow power calculation cycle;

Ø Unable to expand more sensors;

Ø Can not be used portable;

Ø Only basic power calculation and analysis can be done.

ADVANTAGES OF DEVCRO POWER ANALYZER:

Ø It integrates multiple instrument functions (power analyzer, oscilloscope, data recorder, spectrum analyzer, CAN recorder);

Ø Up to 16 phase test（ DEWE3-PA8 ）, data synchronization of all channels;

Ø Data is stored in the system in a unified data format;

Ø Simultaneous power analysis and original data recording;

Ø Real time power calculation (1ms value);

Ø Advanced power calculation and analysis;

Ø Any number and type of input channels;

Portable operating system;

Ø Sensor software calibration.

From the above series of comparisons, it can be seen that the power analyzer is very different from the DVC power analyzer. In the testing of electric vehicles, the traditional power analyzer can no longer meet the requirements of electric vehicle testing, while the power analyzer of DVC can meet the requirements of electric vehicle testing.
