Record the output voltage, current, and control signal of an EV quick charger simultaneously and conduct operational evaluation tests.
With increasing focus on electric vehicles from the perspective of environmental protection and the optimization of energy sources, the energy consumption efficiency of quick chargers (also known as DCQC or DC quick chargers) is an important measurement and evaluation criteria that is indispensable for the advancement of electric vehicles in society. In an electric vehicle (EV), the electronic control unit (ECU) specifies the optimal charging current depending on the battery conditions and provides commands to the quick charger to deliver the correct amount of DC power. Because various signals come into play when determining the right amount of supply, the ability to measure all signals at the same time to determine proper operation and signal integrity is critical for the development and evaluation of quick chargers.
•Simultaneously record the output voltage, current, and various signals of a charger and monitor their &ming during the development of EV quick chargers.
•Directly input up to 1000 V DC (700 V AC) to the MR8905 Analog Unit. All channels are isolated from one another, ensuring safe testing.
•The MR8904 CAN Unit lets you freely select the signals that flows to the CAN Bus and convert them to analog and logic signals.
•Record waveforms over a long period of &me.
When recording to the MR8875’s internal memory using all 16 channels, 1 second of signals can be sampled at the 2μs sampling rate. When saving in real-Dme to the Z4003 8GB SD Card using all 16 channels, 11 minutes and 11 seconds of signals can be sampled at a 10μs sampling rate.
*Measurement requires input unit and other dedicated opDons. Select the input units appropriate for the number of data channels and signal type.
