Charging at off-peak hours, usually from the late evening until the early morning, is important to not strain the local distribution grid. Utilities often offer cheaper, off-peak rates as well, which can lower overall fuel costs. Automakers and charge station providers are developing software for car charging, such as this application from charge company Ecotality which is running on Cisco's Home Energy Controller. A person can schedule charging to ensure a car is full in the morning while getting the cheapest rates. It also shows total money spend on electricity for fuel and the equivalent savings from not using gasoline.
