Abstract
A power sharing device allows a single high voltage electric socket to be shared with one or more appliances and an EV charger. The device can be easily installed and used without updating the electric circuit of the dwelling. The device senses the load of the appliance socket(s) and automatically disconnects the EV charger socket if significant current is being drawn by the appliance(s). The device may also include a circuit breaker to prevent current overload of the electric circuit. These and other features of the device provide improved safety relative to existing solutions.

- a power input that connects to a high voltage socket;
- an electric vehicle charging socket mounted within the housing;
- an appliance socket, mounted within the housing, having a first hot wire and a second hot wire within the housing;
- and
- an alternating current switch, disposed within the housing, connected to both the first hot wire and the second hot wire, wherein the alternating current switch causes disconnection of power to the electric vehicle charging socket responsive to an amount of current in the first hot wire and the second hot wire exceeding a draw threshold without causing disconnection of power to the appliance socket.
