Abstract
A tester connects with the connector of electrical vehicle service equipment (EVSE). The tester simulates the battery supply of an electric vehicle to test whether the EVSE is properly operating without requiring that the electric vehicle be present. In one embodiment LEDs are employed to indicate whether the EVSE meets specifications. In a second embodiment various measurements of voltage levels and signals are provided to allow for a more detailed analysis of the performance characteristics of the EVSE. Ground fault, proximity sensor, and re-closure tests are also undertaken.
Claims20
A tester for electric vehicle service equipment (EVSE) for charging the battery power supply of an electric vehicle comprising:
- a housing;
- a control panel accessible exteriorly of said housing and comprising a switch and a plurality of indicators;
- an EVSE connector inlet disposed for access exteriorly of said housing;
- and
- circuitry comprising a microprocessor disposed in said housing and in communication with said inlet, said switch and said indicators;
- wherein upon connecting an EVSE connector to said inlet and activating said switch to an ON mode, said circuitry simulates the battery power supply of an electric vehicle and activates indicators indicative of performance characteristics of the EVSE.
A tester for electric vehicle service equipment (EVSE) for charging a battery power supply of an electric vehicle comprising:
- a housing;
- a control panel accessible exteriorly of said housing and comprising an electronic display and a plurality of switches;
- an EVSE connector inlet disposed for access exteriorly of said housing;
- circuitry comprising a microprocessor disposed in said housing and in communication with said inlet, said display and said switches;
- wherein upon connecting an EVSE connector to said inlet and selectively activating various switches, said circuitry simulates the battery power supply of an electric vehicle and said display generates measurement values indicative of performance characteristics of the EVSE.
A tester for electric vehicle service equipment (EVSE) for charging the battery power supply of an electric vehicle comprising:
- a housing;
- a control panel accessible exteriorly of said housing and comprising a plurality of switches and an electronic alphanumeric display;
- an EVSE connector inlet disposed for access exteriorly of said housing;
- circuitry comprising a microprocessor disposed in said housing and in communication with said inlet, said switches and said display;
- wherein upon connecting an EVSE connector to said inlet and selectively activating said switches, said circuitry simulates the battery power supply of an electric vehicle and activates said display to indicate various tests and to display performance characteristics of the EVSE which result from said tests.
The tester of 19 wherein the performance characteristics comprise at least one characteristic selected from the group consisting of a signal level, a voltage level and a pulse width.
