Abstract:
1. A power sharing device comprising: a first electrical input which connects with a service panel; a first electrical port which connects with at least one household utility in electrical power communication with said first electrical input; a second electrical port which connects with an EVSE and is in selected electrical power communication with said first electrical input via a relay; a current sensor which senses the utility current through said first electrical port; a microprocessor responsive to the current sensor and which controls the relay to allow full power charging to the second electrical port when the utility current is below a threshold and transmits an output to reduce the power to the EVSE when the utility current exceeds the threshold and continuously monitors the utility current so that when said utility current decreases below the threshold after a pre-established time delay, the relay is actuated to allow full power charging to the EVSE.
