Global Wireless Power Transfer Systems Market: Key Research Findings 2020
Yano Research Institute (the President, Takashi Mizukoshi) has conducted a survey on the global wireless power transfer systems market and has found out the trends by application, the trends of market players, and the future outlook.
A wireless power transfer system is a system to supply power by means of electromagnetic induction, electric field coupling, magnetic resonance and microwave, without any wires or cords needed. Wireless power transfer technology has been employed since 1990s chiefly in some of small home appliances. At that time, applications were limited to between specific products, where each maker originally had standards on their own, which led to formation of a number of exclusive markets. In 2010, WPC (Wireless Power Consortium) established Qi standard, which gained ground and many products have become equipped with Qi-compliant wireless power receivers.
Size of the global wireless power transfer systems market (wireless power receiver modules and devices) in 2019 attained 161,099 million yen, 107.6% of the size of the previous year, based on the shipment values at manufacturers. When observing the market size by application, small electronic devices drove the entire market, while introduction of industrial machinery increased to bring about stable growth every year. On the other hand, application of EVs (electric vehicles) has not shown full-scale growth yet, but is nevertheless regarded as promising market with potential to grow on a large scale. Wireless power transfer systems have yet to be introduced to diverse areas such as home appliances, medical equipment, etc.
Wireless Power Receiver Modules to Smartphones Can be Standard Feature, While to EVs May Take Time
Applications of wireless power transfer systems can be categorized into: 1) Small electronic devices, 2) EVs, 3) industrial machinery, and 4) other applications.
As for application of small electronic devices, wireless power receiver modules are planned to be preset into any high-spec, high-end smartphones hereafter. Furthermore, smart devices, not limited to smartphones, and any PC related appliances are likely to be fully equipped with wireless receivers by around 2030, which can expect further market penetration.
Stricter environmental regulations and EV-promotion policies at each country have driven the sales of EVs especially in China. However, shorter driving distance available and higher prices than internal combustion locomotives have been the obstructions. Introduction of wireless power transfer systems is likely to enormously affect permeation of EVs, but there still are some issues to solve for preparing power transmission infrastructure, which is likely to take more time.
Wireless power transfer systems are increasingly employed in industrial machinery, mainly AGVs. Currently, those wireless power transfer systems for AGVs are chiefly used at automotive assembly plants, but recently, increasingly demanded at warehouses for fulfillment, as more warehouses have been automated. Many attempts have been made to build intelligence in warehousing systems in and out of the country to prevent fulfillment workers from walking around. Today, Amazon has deployed AGVs that can lift store-shelves and move around the warehouse, while First Retailing, the parent company of UNIQLO, allied with Daifuku to co-develop automatic warehousing systems which reduced manpower by 90%. Against such backdrops, increasing number of companies that had already entered the wireless power transfer systems market started considering AGV business entry, which is likely to generate even-fiercer competition.
Because wireless power transfer systems do not need connectors and contact electrodes, they can reduce power charging space and facilitate water proofing as well as dust proofing, which can assure safety of implementation even at a place where water is used frequently. In addition, for many devices equipped with batteries that needed to secure space for large-capacity batteries to achieve longer driving or working hours, they no longer need such space if they can receive power frequently from wireless power transfer.
On the other hand, there are some challenges to solve for wireless power transfer systems to put them into practice: Some kind of control systems is needed for verifying starting and stopping of power transmission and reception, and authenticating power receivers, and also for maintaining highly efficient power transmission. In order for these to take shape, the entire system requires small, thin, and light-weighted implementation.
Currently, the makers of wireless power transfer systems are focusing on new product development to solve the above-mentioned issues and improve existing functions. New products to enable power transfer to remote locations and to multiple appliances, and power transmission to ever-moving machines are expected to be developed from hereon. By enabling these, the power transfer systems market (wireless power receiver modules and devices) is projected to rise to 273,906 million yen by 2030, based on the shipment values at makers.
