Cover letterThe genre I chose is the Frequently Asked Questions. This will be an effective way to explain the Electric Vehicle technology to a non-expert audience. I do not want to explain the fundamentals of the technology and who an electric vehicle works, just the relevant information about the performance of these vehicles. This publication might be posted on an environmental page like , . The audience will be people interested in Electric Vehicles. This audience includes people that understand the environmental implications of conventional vehicles and people who want to invest in green technology. FAQs about Electric VehiclesIs there a difference between a plug-in electric vehicle, a hybrid electric vehicle, and an all-electric vehicle?Yes. A hybrid electric vehicle has an electric motor and an internal combustion engine. These vehicles cannot accept a charge from an external source, and these vehicles make their own charge by the internal combustion engine and by converting the kinetic energy of the car into electricity. This electricity can be stored in the car batteries. Plug-in electric vehicles share some characteristic with hybrid electric vehicles, but the difference is the number of batteries because plug-in electric vehicles can be recharged from the electric grid. Finally, “all electric vehicles” vehicles do not have and internal combustion engine. Plug the in is the only method to power these vehicles.What is the best electric vehicle for me?That depends on your driving needs. An all-electric vehicle can be used to drive less than 80 km per day. For longer distances and more flexibility in the source of power, a plug-in hybrid vehicle is the best option. The hybrid vehicle has been replaced for the plug-in electric vehicle over the last 3 years. Will electric vehicles have a positive impact on the environment?Yes. We can measure and compare the net emissions of conventional an EV by the Well-to-wheels emissions parameter. This parameter includes the energy and materials to produce and power the vehicle, many researchers concluded that EVs have a lower whells-to-wheels emission than conventional vehicles. The inclusion of electric vehicles to the vehicle fleet will reduce the GHG emissions and consequently, improve the air quality. 2489207048500How long will it take to charge the battery of the vehicle? -26638251241922Plug-in EV0Plug-in EVThere are three level of charge, each with a different infrastructure that requires a different length of time. Level 1 is included in all electric vehicles. This level uses the standard voltage of 120 V and the battery can be charged in your home in a period of 5 to 15 hours. Level 2 is a 220 V charge, to support this system the customer has to install a special electric outlet, but the battery can be charged in 4 to 7 hours. Finally, the DC fast charge is a system that is not included in all the EVs. This process uses a very high voltage that can charge the battery in 30 minutes. The DC fast charging technology could be used in highways. However, right now is in the prototype stage. Is cheaper to use an electric vehicle instead of a conventional vehicle?The price of this technology has two components: the investment, which is the cost of the car, and the cost of charging/filling the tank. The cost of an electric vehicle is higher than a conventional vehicle, about 20-30 k dollars, but this cost is decreasing each year due to the improvements in the battery. The cost of charging the battery is less than filling the tank with gasoline. The cost is comparable to paying $1 per gallon of gasoline. The price is lower if the customer charges the car in the night. Are the EV safe as conventional vehicles?Sure. The main structure and safety pack is made with the same materials. The same safety standards apply for EV. One major concern for the people is the battery. The current battery technology is acid-free, is a solid material inside the battery that is not a hazard for the people, even in a car accident. How long do Electric Vehicles last?We spect, as customer, a life time comparable to conventional vehicles. This life time is about 15 years. Because this is a new technology we can not tell if the average life time is 15 or less years. But, firs generation of EVs that appear in 1999, are still on the road.
