IDTechEX, Date of Publication: Apr 18, 2017, 183 Pages

Contactless, inductive and RF charging: consumer, medical electronics, electrics and EVs land, water, air

This unique commercially oriented report has 180+ pages packed with detailed market and technical analysis with many new infograms, conference slides, roadmaps and ten year forecasts 2017-2027. It is based on global research by PhD level multi-lingual analysts in 2016-7 with frequent updates. The Executive Summary and Conclusions is insightful, detailed yet easily assimilated. An introduction gives an overview of the background and technologies with a frank assessment of why most manufacturers and analysts have been over-optimistic about the use, though not always the deployment of these systems in the past and the significance for the future of new capabilities such as long range phone charging. Other chapters embrace the different applications, technologies and roadmaps.

The report primarily discusses mobile phone and electric cars charging but showing how much the same arguments apply to many electrical and electronic goods, particularly mobile ones. Most analysts forecasting sales of contactless charging systems for phones and pure electric cars have over-estimated both over the last 15 years. In response to customer demands, may other aspects were being fixed first. People wanted better features and more of them with their phones, larger screens and so on. Electric cars were held back by range anxiety, high up front price, poor resale price and the need to change driver behaviour such as driving more carefully and finding and using charging stations, usually incompatible ones with a profusion of different payment methods and Tesla ones banned to anyone else. These impediments are gradually being overcome so consumer needs relevant to wireless charging come nearer to the top nowadays. Beware though. The report exposes how the charging needs and solutions for phones and the like have important differences from the needs and uses for vehicles and contentiously, it translates this into value sales for electric vehicles overtaking those for phones within the decade.

The report is extremely comprehensive. It looks at the activities of many developers and manufacturers and their potential customers and users.  The report reveals how mobile phone users do not want contactless charging as such but rather they need ubiquitous charging without carrying a charger around or better still, no loss of use through lack of charge. It contrasts electric vehicles where the act of plugging in in public places can he a physical strain, dirty and dangerous but the environment is more challenging with roads being dug up, animals getting irradiated and ground clearance varying greatly and obscuration a problem. However, the reader can form their opinion based on inputs from all parts of the value chain and from other interested parties. To dig deeper on certain aspects, IDTechEx has many new reports and consultancy services on allied topics such as post-lithium batteries, extreme lightweighting and wearable electronics.

This report purchase includes up to 30 minutes telephone time with an expert analyst who will help you link key findings in the report to the business issues you're addressing.
