  • High-precise current & voltage measurement
  • Easy-to-mount and flexible sensors (battery, PTC, AC,…)
  • Automatic energy balance report


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 measurement cables need to be guided inside the motor- or compartment room. Shunt-based current sensing with automatic temperature correction allows measuring very low currents (50 mA) as well, as very high currents (500 A) for the whole operating temperature range with highest accuracy - without any influence of shielded motor cables.

The Report Generator gives you an excellent overview of your electric vehicle - detailed analysis for different driving situations (e.g. energy consumption from 40 to 50 km/h) as well as energy balance charts, statistics and motor evaluations are just some of the features.
