Power and efficiency analysis on heavy-duty electric powertrains
Heavy-duty vehicles and trucks often utilize multiple electric motors. This architecture makes power and efficiency tests particularly challenging. It also has an impact on measurement technology, which becomes particularly clear when analyzing the electrical power in performant heavy-duty powertrains. The electrical power measurement is the starting point for all further analyses; for example, the recording of efficiency or the energy consumption measurements during test cycles. Power measurements must be carried out with a high-voltage-safe e-mobility measurement system and a high sampling rate; electrical power values must be calculated in real time.
