This project addresses the challenge of recharging Plug-in Hybrid Electric Vehicles (PHEVs) efficiently and without user intervention. As concerns about CO2 emissions grow—especially highlighted during the 2009 Copenhagen conference—the adoption of PHEVs is expected to cut greenhouse gases significantly. Our design envisions an auto-connection system that allows PHEVs to charge automatically when parked and disconnects safely upon departure. This innovative solution simplifies the charging process, ensuring users won't forget to recharge, and integrates seamlessly with home power systems.

  2. Problem Statement Taken from Frost & Sullivan by Sarwant Singh

  3. Problem Statement • There has been an ever increasing concern about the amounts of CO2 emissions being released into the atmosphere from vehicles resulting in the recent Copenhagen conference in December 2009. Plug-in hybrid electric vehicles (PHEV) have gained popularity in recent years as a popular choice among some people especially in developed countries. Some studies suggest that a broad acceptance of PHEVs by 2050 could cut up to 6.12 billion tons of greenhouse gases each year which is approximately 2.5 times the amount currently emitted by power plants. There is an expected deployment of 1 million PHEVs by 2015 as announced by President Obama’s New Energy for America.

  5. Problem Statement • A major problem faced by people who own PHEVs is that recharging their car often requires a plug-in device which involves manual effort from the user. The scope of this project is to envision a system that has a capability to charge a PHEV without the need of labor while at the same time ensuring safety. One of the major benefits of this device is that there is no need of the user to remember to charge the vehicle.

  6. Problem Statement • The system is likely to involve an auto-connection upon parking the vehicle and an auto-disconnect upon shifting out of park. A single modification to the infrastructure is needed to fully integrate the electric vehicle with the power grid through the home.

  7. Design Partition • Receptacle Several types of receptacles depending on power needed to charge the vehicle. a. Typical golf cart charger b. Charger for a HPEV

  8. Design Partition • Auto Connect (Alignment) • Magnets • Headlights/ lasers • Funnel – vertical • Funnel – horizontal • See-saw design • Pressure sensor/ lift

  9. Design Partition • Disconnect A method to disconnect the charger from the vehicle once it is fully charged

  10. Design Partition • Power The vehicle will be charged from a ~110 V AC electric outlet in the garage
