The electrification of the powertrain leads to new challenges in the field of measurement technology. All components and the interaction of the drive train must be tested. This includes the primary energy storage ("battery"), the power electronics, the electric motors, if necessary intermediate energy storage as well as the entire control and regulation of the drive and energy supply. Due to the high-voltage components in purely electrically operated vehicles, there are high demands on the measurement technology.
Furthermore, the power measurement during charging, but also the torque development at the wheels, is included in the energy balance and efficiency of electric vehicles.

파워트레인의 전기화는 측정 기술 분야에서 새로운 도전으로 이어집니다. 드라이브 트레인의 모든 구성 요소와 상호 작용을 테스트해야 합니다. 여기에는 기본 에너지 저장 장치("배터리"), 전력 전자 장치, 전기 모터, 필요한 경우 중간 에너지 저장 장치는 물론 드라이브 및 에너지 공급의 전체 제어 및 조절이 포함됩니다. 순수 전기로 작동되는 차량의 고전압 부품으로 인해 측정 기술에 대한 요구가 높습니다.
또한 충전 중 전력 측정과 휠의 토크 개발도 전기 자동차의 에너지 균형과 효율성에 포함됩니다.
