ClipperCreek’s new CP-50 hand-held EVSE tester

Charger manufacturer ClipperCreek has released a compact hand-held EVSE testing tool designed for installers, technicians and facilities maintenance personnel.

The new CP-50, priced at $250, can be used to test a Level 1 or Level 2 EVSE installation without a vehicle present. It can function as a stand-alone device or in combination with a digital volt meter and/or oscilloscope to verify operations and troubleshoot an EVSE.

The CP-50 offers test points to view SAE J1772 pilot signal at various states, as well as cable/connector troubleshooting. Designed for use with ClipperCreek EVSE, it should be compatible with all other makes and models of Level 1 and Level 2 EVSE on the market.

Primary functions include:

  • Verifying EVSE operations without a vehicle
  • Simulating vehicle connected and charge requested
  • Simulating CCID charging fault to ensure EVSE safety circuitry is functioning properly

Pair the CP-50 with a digital volt meter to:

  • Measure incoming service voltage, each line to ground and line to line
  • Verify SAE-J1772 connector proximity switch resistance is within specification range
  • Conduct advanced cable/connector troubleshooting

Pair the CP-50 with an oscilloscope for:

  • Easy access test points to view SAE J1772 pilot signal at various states (i.e. vehicle connected, charge requested)

“The CP-50 delivers a variety of test capabilities in a compact, easy-to-carry form factor,” said ClipperCreek Customer Support Supervisor Charles Douglass. “The CP-50 is already being utilized in a variety of applications including installation verification, vehicle compatibility diagnostics, and preventative maintenance testing. We use it regularly in the lab to reproduce charging issues, and it is a valuable tool for any person responsible for installation or ongoing maintenance of EV charging infrastructure.”
