battery. The battery is charged through regenerative braking and by the internal combustion engine and is not plugged in to charge. 2. Plug-in hybrid electric vehicles(PHEVs)are powered by an electric motor. Conventional or alternative fuel is used to power a gas generator that allows the electric motor to continue to operate;hence extending the distance the vehicle can travel. The vehicle can be plugged into an electric power source to charge the battery. Some types of PHEVs are also called extended range electric vehicles(EREVs). 3. All-electric vehicles(EVs)use a battery to store the electric energy that powers the motor. EV batteries are charged by plugging the vehicle into an electric power source.EVs are sometimes referred to as battery electric vehicles(BEVs). There are a number of organizations and communities that have adopted the use of electric vehicles into their fleets such as the Minnesota DNR and the city of St.Paul. There are also a number of utilities who have installed electric vehicle charging stations,such as; Wright Hennepin Electric,Connexus Energy, and Xcel Energy. The focus thus has been on educating city staff on the types of vehicles,travel ranges, and maintenance concerns of this technology. There are drastic differences in the costs of the charging units and their charging rates because of the vast differences in charging times and equipment. The type of electric vehicle and charging station technology must be coordinated to ensure proper energy supply. ERMU is evaluating charging equipment options and possible grants to decrease the upfront cost of the charging stations. The vehicle charging equipment has three levels at this time: 1. Level One charging only requires a standard household 120 volt outlet. One hour of level one charging will provide 4.5 miles of range and it takes approximately 22 hours to attain a full charge.The level one charger is the most affordable;however,the slow charging process is inconvenient and does not aid in eliminating range anxiety. It allows for a lower demand charge over a longer period of time. 2. Level Two is a step up in charging and is equivalent to connecting your car to an electric dryer or stove outlet. It requires 240 volts instead of the level one 120 volts. This is still relatively cheap to install in a home and cost estimates are less than$1,500. These chargers provide for a wide range of charging but maximum estimates are approximately 70 miles per hour of charging,or about 8 hours for a full charge. 3. Level Three is the DC Fast Charge. This is the type of charging that will not be found in a home. This charging equipment requires 480 volts. The charging unit actually converts the alternating current(AC)of standard electricity to Direct Current(DC)prior to it being transferred to the battery in the car. The other charging methods utilize inverters in the electric vehicle to convert it to the DC electric. The DC Fast Charger can provide up to 20 miles of range in just 10 minutes. That would be equivalent to 120 miles of range provided in one hour. These types of chargers have been vital to increasing the electric vehicle charging network throughout the state and are decreasing range anxiety as they provide a relatively quick charge for travelers. They are also important to organizations utilizing electric vehicles in their fleets. ACTION REQUESTED: Staff is not requesting any action at this time. Staff is providing information to keep the Commission informed of the research being conducted and ask for input on the potential of electric vehicle options and programs that may be provided to the City of Elk River and the community.
