Report sees 10x growth in electric chargers over the next decade

October 01, 2018 // By Nick Flaherty
Over 60 million electric vehicle chargers (both public and private) could be deployed worldwide by 2029, up from 6m today, says a new report by IDTechEx Research. This has significant implications for semiconductor suppliers and management of the power grid.

There were just 3m electric cars in the world at the end of 2017, 0.23% of the global vehicle population. The deployment of electric vehicles will depend on the deployment of ubiquitous chargers, but the emergence of the autonomous, shared vehicle and ride hailing platforms will change the needs of charging infrastructure. 

IDTechEx believes that at some point shortly after 2030 the world might reach peak car in relation with the emergence of autonomous and shared vehicles, the question raises whether an autonomous vehicle will still require a person-operated electric vehicle charger. The answer is probably not, as initiatives are under way to replace such charging infrastructure, including inductive wireless charging and robotic charging. Capacitive charging, a new concept for charging electric vehicles through electric fields rather than magnetic being developed by ARPA-E, is another possibility. One very interesting start-up is integrating magnetizable materials in concrete for wirelessly charging electric vehicles dynamically. 

The report on Electric Vehicle Charging Infrastructure 2019-2029 looks at the state of development of technologies for electric vehicle charging including conductive, inductive, and capacitive charging among others. The report presents the different charger topologies by different levels (Level 1 to Level 3) and the main charging standards of Chademo, CCS, Tesla, China GB dtd and India Bharat std, communication protocols and standards including an analysis of Vehicle to Grid communication interphase. 

The EV charging infrastructure value chain will evolve as the integrating of both electric vehicles and renewable energy goes forward, say the market researchers.Demand side management and key enabling technologies like energy storage will also play a key role going forwards. The report points to companies like Toyota, Hanergy and IFEVS who are working in extending the range of electric vehicle by integrating energy harvesting technologies in them, from solar photovoltaics to small scale turbines. Depending on how these trends may evolve in the following ten years there may be points in time of peak
