/ 49 Automatic detection of the electrical period as well as an automatic calculation of the line voltages out of the measured phase to phase voltages making the use of an external neutral point adapter unnecessary. These and more standard calculations are pre-defined as graphical calculation models, fully extendable according to the engineer‘s need. COMPONENTS OF THE MEASUREMENT CHAIN The AVL IndiModul.xEV is perfectly suited for acquiring raw voltage and current data of electrical systems and making them available to the processing software for online evaluation or data storage. Acquisition is performed in a high speed time-based mode and takes advantage of capturing even transient phases. The AVL HVP-Box is designed for the high voltages of DC and AC circuits on electric or hybrid powertrains. It transforms 4 channels of high differential voltages (±700Vpeak) to ground related low voltages (±10Vpeak). The unit fits perfectly into the CSS-Box and the IndiModul.xEV DAQ-unit. The AVL CSS-Box (Current Sensor Supply - Box) is designed as signal conditioning and supply unit for high precision LEM current transducers. The LEM current transducers allow the measurement of high currents up to 1,000A in the DC and AC circuits of electric and hybrid powertrains. The AVL CSS-Box supports up to 4 LEM current transducers and transforms the output current (±1A) of the transducers to a voltage in the range ±10V by using high precision shunt resistors. APPLICATIONS Pure electric or hybrid powertrains - one system serves all. The IndiModul.xEV can also be operated as slave to a standard AVL indicating system (IndiModul 622, IndiSet 642 or IndiMaster 672) using AVL IndiCom software. In this way combustion data and electric data and results can be stored in a completely time synchronized manner.
