1 Electric Vehicle Energy - Efficiency - Testing

2 Introduction - Energy & Efficiency analyis New registrations of electric vehicles hit each year a new record. The technology is developing fast, especially to increase performance and range of electric vehicles. The determination of the energy consumption is already a well-discussed topic as results can deviate heavily from the manufacturers specification. Tests according to old driving cycles (like the NEDC) are not sufficient. Hot or cold weather conditions as well as the driving behaviour and driving route can influence the results significant. The new defined driving cycle WLTP and especially the coming Real-Drive-Tests (RDE) should ensure more reliable energy consumption specifications. Hardware The EV-POWER sensors are designed exactly for the needs of accurate energy consumption measurements at electric vehicles... at all driving conditions. The sensors are easy-to-mount (any kind of HV connector possible) and safe measurements are ensured. There are no modifications at the vehicles needed and no high-voltage cables for measurement need to be guided inside the motor- or compartment room. Shunt-based current sensing with automatic temperature correction allows measuring very low (50mA) as well as very high currents (500A) for the whole operating temperature range with highest accuracy. Further voltage and current are measured without the shield of the HVcables (typically the problem using current clamps). Easy integration of GPS, Video, CAN-data and other analog & digital signals (see DEWEnet brochure) complements the hardware features. Software The connectivity allows you to choose the ideal software for your application. Whether you integrate the sensor in existing CAN-based measurement systems (dbc-file), or using DEWESoft for dynamic measurements... or using the state-of-the art CLOUD solution which is an unique tool for fleet testing or Real-drive tests as you can access the data all over the world. Report Finally, report generation templates should support you to get test reports as fast as possible... after or during your testdrives. Analysis for different driving situations (e.g. energy consumption from 40 to 50 km/h) as well as energy balance charts, statistics and motor evaluation gives you an excellent overview of your electric vehicle.
