corridor with access to electric power, and at an acceptable cost to ERMU. ERMU was also <br /> responsible for finding a certified installation contractor. ERMU solicited bids from local <br /> contractors for the installation of the units and worked with them to become certified <br /> installers/partners of the ChargePoint equipment. <br /> The first station was installed on June 23, 2016. It was a level 2 station, which was easier to <br /> install because they operate on 240 volts and in this case did not need any additional <br /> distribution upgrades such as a new transformer. ERMU partnered with the City of Elk River's <br /> Economic Development Authority to locate it in the historic downtown business district. ERMU <br /> and the City entered into a license agreement to utilize the parking spaces, with no cost to <br /> ERMU for this license agreement. ERMU was able to use an existing transformer located in the <br /> parking lot to serve the charging equipment. <br /> The site was a good choice for a level 2 charger because it was close to a city park and trail, had <br /> available parking spaces, and had retail shops and restaurants within walking distance. The area <br /> surrounding the parking lot provided many entertainment options to support a longer charging <br /> session. Area businesses will benefit from attracting electric vehicle drivers to shop and eat <br /> while they charge at the level 2 station. <br /> Use of Public Charging Stations <br /> Based on the collected data in Table 1 and Figures 1 & 2 below, the conclusion is that the DC <br /> Fast Charger users are taking advantage of the high-power charging capacity with more than 95 <br /> percent of the charges lasting an hour or less. Slightly more than 60 percent of charges on the <br /> Level 2 chargers are an hour or less.The convenience of the DC Fast Charger is preferred by EV <br /> drivers who are "topping up" their vehicles. <br /> Table 1 <br /> Level 2 (240 Volt) DC Fast Charger(480 Volt) <br /> Charging Session Length Number of Percent Number of Percent of <br /> (Hours:Minutes) Charges of Total Charges Total <br /> 0:30 22 29.7% 117 78.0% <br /> 1:00 23 31.1% 28 18.7% <br /> 1:30 15 20.3% 4 2.7% <br /> 2:00 4 5.4% 1 0.7% <br /> 2:30 3 4.1% 0 0 <br /> 3:00 4 5.4% 0 0 <br /> 4:00 1 1.4% 0 0 <br /> 5:00 1 1.4% 0 0 <br /> 6:00 1 1.4% 0 0 <br /> 12 <br /> 51 <br />
