Electric Vehicle Service Equipment (EVSE)



TESCO has more than 110 years of experience in designing and building devices to test the accuracy of electrical measurement devices for the utility industry. From that knowledge and expertise, TESCO has developed a means to check the accuracy and calibration of Electric Vehicle Chargers with its Electric Vehicle Service Equipment (EVSE).

TESCO’s family of Electric Vehicle Service Equipment Testers provide complete test capabilities for EVSE systems conforming to J1772_201602. Fully compliant with Handbook 44 provisions, they test the accuracy of energy delivered using a transactional model. Full communication signal analysis and safety checking of the EVSE connection is provided.

With the rise of electric vehicles, there needs to be an easy and accurate way to test electric vehicle charges.  Test the accuracy of DC chargers with TESCO’s Test System 400.  The TS400 is a valuable instrument with complete test capabilities and caters to every possible EVSE charging protocols in the world (AC and DC).

TESCO’s EVSE Test Systems tests the accuracy of energy delivery using a transactional mode compatible with HB44 provisions.

The TS400 tests AC Level 1 and Level 2 systems up to 64 amps maximum current and DC Fast Charge systems up to 300A at 1000VDC. The TS400 Set includes a PL4000 Load Emulator for complete freedom and test automation. Any J1772 compatible EV can also be used as the test load by using an optional cable.
