Researchers at the University of Michigan have conducted a study to determine the ideal number and locations of EV charging stations across Michigan highways. The Michigan Energy Office (MEO), which funded the study, will use the results as it allocates $9.9 million over the next three years for public EV charging stations across the state.
The study accounted for future projected EV demand and considered low, mixed, and high technology scenarios. The low-tech scenario called for 43 charging stations, 600 charging outlets, and a $28 million investment. The high-tech scenario called for 24 charging stations, 131 charging outlets, and an investment of $14.6 million. The mixed scenario, which was recommended by the study, called for 35 charging stations, 196 charging outlets, and an investment of $21.8 million. This scenario anticipates 70 kWh batteries and 150 kW chargers, as well as the need to accommodate smaller and older EVs.
“This first-of-its-kind study will prove invaluable to Michigan regulators, policy makers, utilities, EV charging companies, municipalities and others as the network of fast-charging stations is developed along Michigan highways,” said Robert Jackson, director of the MEO.
The MEO is aiming to develop an effective DC fast charging network throughout Michigan by 2030. The next phase of the study will look at the placement of urban EV chargers. The study incorporates the input of stakeholders such as EV drivers, utilities, auto companies, charging station operators and other state agencies.
