Spectrum Analyzer for EV
The power-net in EV or xEVs with the DC voltage of power battery PACKs contains several HVEE (High Voltage Electrical & Electronic) units, such as Battery, PDU, PMU, Powertrain, PTC, Air-conditioner, ESP ... in different vehicle design, which result in specific voltage and power characteristics with different operation status and environment.
For quality assurance and service life design, the related simulation for an EV is normally basis for effectively evaluation, and in problem diagnoses or failure mode analysis it is much more an important tool to use.
With sufficient and complete spectrum or impedance measurement the simulation for EV power-net can be compared or verified so that further analysis on the operation performance or failure reason will be reliably depend on simulation models.
Stropower Spectrum Analyzer for EV is basically the ripple response based spectrum analyzer, to measure the AC impedance with real AC power signal that the noise bands interferences will be relatively small enough.
The system can generate enough AC stimulus signal superimposed on DC currents through the coupling unit and measure to report the detected information for interest, such as peak or peark-to-peak voltage, current and impedance over frequencies from 10 Hz to 200 kHz.
With the specially developed Impedance Measurement block in ENOVA (Stropower server software for the test system), users could run the test with different configurations and in the mode of frequency sweeping so that the test process can be automatically finished within several mins per cycle.
The system is also complete function equipment for HV DC supply, AC ripple generator and can conduct linkage test with different CAN / Ethernet interfaces that surrounding the test system, such as drive bench, cooling chiller or digital sampling units.
