When this battery is A hybrid vehicle uses two or more power sources to depleted, the original Prius battery kicks in to provide propel the vehicle. A standard Prius hybrid electric power as originally designed by Toyota. When driven vehicle (HEV) is powered by a gasoline engine and at lower speeds, 34 mph or less, this PHEV can travel an electric motor. The electricity powering the motor as far as 30 miles on a single charge without using comes from an onboard battery. The battery is charged gasoline. by the engine and by vehicle braking and deceleration.

MGE contracted with A123 Hymotion to add another, larger battery—one that is charged with grid power via an electric cord plugged into a standard 120-volt outlet. This battery is installed in the back where the spare tire typically is stored. While a standard Potential future benefits Prius is estimated to achieve 45 miles per gallon (mpg) As our utility grid is increasingly powered by renewable of gasoline, this modified Prius may achieve over energy sources, PHEV technology may: 100 mpg. • Reduce greenhouse gas and air pollution emissions We have also installed a fully automated monitoring • Reduce reliance on non-renewable fossil fuels device that will monitor such things as fuel efficiency, electricity use, engine function and GPS data. This • Reduce reliance on foreign sources of oil device will communicate directly with the federal Other features Department of Energy Idaho National Laboratory • Five hours to fully charge the added battery and will allow MGE to participate in and learn from a national study of various PHEV technologies. • Battery holds about 5 kWh of electricity • At today’s prices, costs about $0.65 to fully charge As with other MGE technology demonstration projects, the battery we will share what we learn from this project on our Web site.
