The electric grid has a grid usage level and a grid capacity. The charging system includes a plurality of stages that each include a battery charger for charging an electric vehicle battery, a controller, and a charging relay. A current sensing unit inductively measures the current on the charging conductor and provides a sensed current to the controllers. When the grid usage level is low the battery chargers on all stages are active. As the grid usage increases toward peak usage, in response to an increase in the sensed current, the controllers consecutively deactivate the battery chargers at predetermined threshold levels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charging system utilizing excess grid electricity","description":"An electric vehicle charging system, for use with an electric grid having live conductors including a charging conductor, and a neutral conductor.
