Take a look at the performance and security {of electrical} automobile charging stations, simply and reliably

Take a look at the protection and efficiency of sort 1, degree 1 or degree 2 electrical automobile ac charging stations (EVSEs) with the Fluke FEV100. This take a look at adapter simulates the presence of {an electrical} automobile, permitting you to conduct exams together with acceptable take a look at devices corresponding to a digital multimeter or oscilloscope. Use the FEV100 to confirm an EVSE is working correctly after set up and through periodic upkeep, or troubleshoot an EVSE if it isn’t delivering the suitable cost.


EVSE charging cables could turn out to be broken over the course of use, rising electrical shock dangers to customers. Keep shielded from and examine threat of electrical shock with the GFCI journey take a look at. This operate verifies the breaker of the EVSE is linked by detecting floor faults. Moreover, the PE grounding safety pre-test verifies that there is no such thing as a presence of harmful voltage on the floor terminal.

Simplicity and comfort 

Carry out quite a lot of exams together with floor fault checks, insulation of wires, measuring voltage and responsibility cycle to see max present obtainable for charging all with one adapter that safely integrates with the Fluke portfolio of take a look at and measurement instruments. There isn’t a have to carry an electrical automobile onsite for EVSE troubleshooting: the adapter acts as an electrical automobile when linked to an EVSE for simple efficiency and upkeep testing.

Easy methods to take a look at a charging station 

As soon as an EVSE acknowledges it’s linked to a “automotive” and is prepared for charging, the adapter exams if the EVSE is performing the best way it ought to be. 

  1. Carry out the protection grounding safety pretest to confirm that no harmful voltage is current within the grounding circuit. If the indicator lights up, it’s doable that {the electrical} wiring has been arrange improperly or there’s a grounding malfunction. On this occasion cease additional testing instantly and examine for a doable wiring fault of the bottom conductor. 
  2. Confirm station output voltage utilizing a further meter, such because the 87V digital multimeter. 
  3. Confirm station most preset cost present utilizing CP terminals and a meter with an obligation cycle operate or an oscilloscope. 
  4. Simulate the error states as described within the SAE J1772 commonplace: CP error “E”, GFCI journey take a look at, and grounding error.

CP error “E” simulation 

The usual SAE J1772 defines Error “E” as a state when charging station is: disconnected from automobile, disconnected from utility, there’s a lack of utility energy or management pilot is brief to manage pilot reference (floor). This error simulation exams the station to make sure that if there is a matter with the CP of the automobile, the station and utility won’t provide a cost to the automobile. 


Every EVSE is required to be outfitted with GFCI safety. On many stations, the GFCI safety is totally computerized and doesn’t want a guide reset after the GFCI circuit is tripped.

Floor Error (Floor Fault) simulation 

The Floor Error button simulates an interruption of the bottom conductor. Consequently, the pending charging course of is aborted and new charging processes are prevented. Superior exams corresponding to insulation resistance, energy high quality, evaluation of the management pilot waveform and loop impedance can be finished utilizing the adapter at the side of acceptable take a look at and measurement gear. 

Verifying charging voltage with automobile simulation 

The CP state rotary change selector simulates varied automobile states when the take a look at adapter is linked to the charging station. Car states are simulated with completely different resistances linked between CP and PE conductors.
