The use of measurement technology in the high-voltage environment brings with it a number of new regulations and requirements that must be observed. First and foremost is the safety of the operator, which places new demands on the measurement technology.
Currents must be measured at many points in the HV electrical system of modern electric vehicles: Be it to analyze charging and consumption processes or to verify protective measures against shield currents. The precise investigation of high-frequency current components requires a wide bandwidth in measurement, and instrumentation in particular can present users with challenges.
Temperatures play a major role in the performance and safety of vehicles with electric, fuel cell or hybrid drive systems. If the temperatures in components such as the HV battery deviate significantly from their ideal range, performance losses, accelerated wear or even total failure are the result. Accordingly, temperatures must be measured intensively at many points.
DC and AC voltages in the HV environment are characterized by peaks and dips as well as superpositions and have a significant influence on the interaction of all components. To ensure proper operation of the entire system, regulations set limits and must be verified.
For the comprehensive analysis and testing of electric vehicles, physical parameters from numerous sources (HV and low-voltage environment) must be acquired and analyzed. A precise evaluation of the data is only possible through the synchronous acquisition of the data. In addition, the design of such a measurement system should be conceivably simple and precisely tailored to the measurement task.
Electromobility continues to gain momentum. Various energy storage, drive and charging systems pave the way to electric mobility. The development of high-voltage batteries, inverters and electric motors places high demands on measurement technology in order to obtain the right results for further optimization. Together with Vector Informatik, CSM has developed a measurement system that leaves nothing to be desired.
