Vector offers e-mobility measurement for HV and real-time analysis
Software tool and embedded component manufacturer, Vector, now offers an e-mobility measurement system, in collaboration with CSM (Computer-Systeme-Messtechnik), which manufactures mobile measurement equipment and data acquisition systems.
The system enables users to perform fast and time-synchronous, multi-channel measurements in high voltage (HV) cables and components. CSM’s hardware modules and Vector’s measurement software vMeasure exp or CANape, are used by developers to calculate and simultaneously display variables such as active power, efficiency, shielding current and ripple in real time. The e-mobility measurement system can be used to develop electric drives and electric vehicles (EVs).
The measurement software, vMeasure exp, has an integrated function library eMobilityAnalyzer for analysis and real-time calculation. It also includes the certified CSM hardware measurement modules, which provide high voltage safety. The e-mobility measurement system fits seamlessly into the Vector tool chain for easy connection to bus and engine control unit (ECU) interfaces, analysis tools, automated documentation and the measurement data management system. It is suitable for OEMs and suppliers developing components, vehicle electrical systems or prototypes related to electromobility (e-mobility).
Measuring electrical currents and voltages is one of the core tasks for e-mobility. It requires much higher sampling rates than with the combustion engine. The eMobilityAnalyzer generates information from calculated and derived signals, such as energy flow, ripple, power or efficiency. EVs also have multiple ECUs and bus systems whose signals need to be recorded in order to better understand and analyse the interactions between them. The e-mobility measurement system from Vector and CSM records all this data with one synchronised tool, instead of developers having to use multiple suppliers.
The system is scalable and flexible, for measuring tasks on individual components, up to complex analyses of complete EVs. Developers can acquire physical signals, messages from the ECU and bus communication synchronously, and with high precision, in one measurement, says Vector. The e-mobility measurement system makes it easier to identify dependencies, assess quality, check legal requirements and detect possible sources of error quickly. It can acquire measurement data from driver testing, on the test bench and in the laboratory. An advantage is that the developer receives analyses in real time instead of having to carry out evaluations in the laboratory afterwards.
