Communication tester between e-charging station and e-vehicle. The test device is intended for checking the functional behavior of charging stations and electric vehicles with a type 2 connection socket (mode 3 charging). For this purpose, the test device is switched between the charging station and the electric vehicle in order to log the communication between the two participants. If the charging process does not start, the source of the error (charging station or electric vehicle) can be quickly located. The PROFITEST H+E TECH is suitable for use in development and service. Complete diagnosis of e-charging stations and e-vehicles: Vehicle states Cable states Error states Evaluation of PWM signal Phases and rotating field Battery state Display of communication between charging station and electric vehicle in real time Signaling of states using easy-to-understand symbols Simple operation and diagnosis Battery-operated compact device, therefore also suitable for outdoor use. State visualizations Visualizable vehicle states (CP) No vehicle present Vehicle present Vehicle ready for charging without ventilation Vehicle ready for charging with ventilation Cable type (PP) 20 A cable . Connection option for electric vehicles: OEM plug type IICompact case, ideal for service callsLarge display with switchable background lightingUser interface language can be set: D, GB, F, E, I, PTSupply via two 9 V block batteries / rechargeable batteries or power packUSB data interface for firmware updates.
