Abstract
An electric vehicle (EV) charging system is described herein. The EV charging system may be configured to determine if a component in the EV charging system is operating properly based upon current usage. For example, an EV charging station controller may measure a current corresponding to an input to an EV charging station. The EV charging station controller may further measure currents of reference components in the EV charging station, and then use the measured currents to determine if a component in the EV charging station is operating properly. In some examples, the component is a heating, ventilation, and air conditioning (HVAC) component in an EV charging station because it is particularly useful to know the operational status of an HVAC in EV charging systems (e.g., to ensure that the components charging the EV are the correct temperature).
