ELECTRIC VEHICLE CHARGER TESTING SYSTEMS
First Claim
1. An electric vehicle (EV) charger compliance test system, comprising:
- an EV charger connection interface having one or more communication connections and one or more power connections, wherein one or more of the communication connections and one or more of the power connections comply with a first EV charging protocol, and wherein one or more of the communication connections and one or more of the power connections comply with a second EV charging protocol;
a load module connected to the power connections;
a first charging protocol compliance signal generator connected to one or more of the communication connections in compliance with the first EV charging protocol; and
a second charging protocol compliance signal generator connected to one or more of the communication connections in compliance with the second EV charging protocol.

Abstract
Systems, methods, and apparatus relating to electric vehicle (EV) charger testing systems are disclosed and claimed herein. Exemplary systems comprise an EV charger connection interface having communication and power connections complying with one or more EV charging protocols, an electrical load module connected to power connections, and charging protocol compliance signal generators connected to the charger connection interface for simulation of a connection between an EV and an EV charger. Testing systems may be used to monitor, record, and profile the output of an EV charger and determine compliance of the output with one or more EV charging protocols. Additionally, methods related to testing and analyzing charge output of an EV charger are disclosed, including determining which of multiple charging protocols to use while testing the charger.
