Description

The new EVCC300 introduces a new and convenient way
of checking Electric Vehicle charge points. A simple all in
one concept provides an easy to use solution to check
both the safety and operation of level 1 and two phase
level 2 EV chargers. The instrument is ideal for those
wishing to perform a check on an EV charger following
manufacture, installation or repair, or just part of a
maintenance schedule / inspection.

FEATURES

• Four important safety checks:
• 1. PE touch pad to check ground connection and
  hazardous voltages
• 2. PE resistance (RPE) test to check any exposed metal
  work is properly grounded / earthed
• 3. Touch voltage test to ensure the charger ground /
  earth does not rise to a hazardous level when charger
  output is on
• 4. RCD / GFCI protection check by timing the device
  tripping speed. This test causes a calibrated ground /
  earth leakage current appropriate to the trip rating
  of the device to flow and time how long it takes
  for the device to break the supply. If an RCD / GFCI
  was to take too long to trip it would not protect the
  charger user from electrocution, so it is an important
  safety check

• Nuisance charger supply tripping check.
  This test will help determine whether the EV charger
  user is likely to experience nuisance tripping of the
  RCD or GFCI.

  The EVCC300 slowly increases ground / earth leakage
  current until the protective device trips to ensure it
  trips at the correct leakage current level.
  If the leakage current that trips the device is too low it
  will indicate either an issue with the device or there is
  already a high level of leakage present.

• Four key EV charger operation checks:
• 1. Proximity detection operation check. The EVCC300
  can check that proximity is detected and also
  whether, when testing a type 1 connection, that
  latching detection has worked correctly
• 2. Control pilot operation check. Not only can the
  EVCC300 set CP states to operate the EV charger,
  the instrument can read the response state of the
  charger. The codes A, B, C, D, E and F can be set
  by the EVCC300 and the response of the charger
  displayed on the instruments colour display.
  The charger PC state is displayed together with the
  chargers indicated maximum charge current, all to
  IEC61851-1 requirements
• 3. Control pilot signal check. The EVCC300 measures
  the CP signal Voltage, Frequency and Duty cycle.
  Repeated measurements will highlight instability in
  the signal.
• 4. EV charger output check. The EVCC300 measures
  the output voltage and frequency of the EV charger
  when charging in is in progress. When appropriate
  the EVCC300 also checks for correct L – N
  supply polarity.
