The market for plug-in electric vehicles has expanded in recent years in parallel with the deployment of publicly accessible charging stations, mainly funded by government programs.
Today, the large public investments for electric vehicle supply equipment infrastructure that characterized industry growth in North America and Western Europe over the past 3 years are beginning to slow. According to a new tracker report from Navigant Research, there are now almost 64,000 public charging stations installed globally.
“As public investments in charging infrastructure wane, the numerous companies that emerged in the market’s early stages and championed various technologies and business models are now beginning to consolidate and standardize,” says Scott Shepard, research analyst with Navigant Research. “While investment in EV charging equipment technology has been significant during the past few years, the private sector now needs to focus on financing infrastructure deployments in order for the market to continue to grow rapidly.”
Alternating current (AC) installations account for the vast majority of public charging station installations worldwide. AC charging, which is used in both residential and commercial applications, typically supplies capacities of up to 7.2 kilowatts (kW) and, in rare cases, up to 43 kW. Used in commercial applications, direct current (DC) installations typically supply from 20 kW to 50 kW, although some manufacturers have introduced units with power ratings of up to 100 kW.
