Component Power Draw Detection for Electric Vehicle Charging Station

A non-transitory computer-readable storage medium for determining whether a component in an electric vehicle (EV) charging station is operating properly comprising instructions that, when executed, cause a processor to:

• measure a first current, wherein the first current is a current corresponding to an input to the EV charging station;
• measure a current of a first reference component;
• measure a current of a second reference component;
• determine a summed current by summing the current of the first reference component and the current of the second reference component;
• determine a remaining current by subtracting the summed current from the first current;
• and
• apply a comparison rule to the remaining current to determine an operational status of the component.

A computer system for determining whether a component in an electric vehicle (EV) charging station is operating properly, the system comprising:

• one or more processors;
• and
• a non-transitory program memory communicatively coupled to the one or more processors and storing executable instructions that, when executed by the one or more processors, cause the computer system to:
• measure a first current, wherein the first current is a current corresponding to an input to the EV charging station;
• measure a current of a first reference component;
• measure a current of a second reference component;
• determine a summed current by summing the current of the first reference component and the current of the second reference component;
• determine a remaining current by subtracting the summed current from the first current;
• and
• apply a comparison rule to the remaining current to determine an operational status of the component.
