ENERES Co., Ltd.

As a full member of the Wireless EV Alliance, Eneres Co., Ltd. has launched a new working group “Examination of New Services Utilizing EV Wireless Power Transfer” (hereinafter, “the WG”).
We will proceed with examining business models unique to wireless power transfer that create adjustment capacity and economic benefits by integrating energy resource aggregation mechanisms with the wireless power transfer systems that will be built in the future.

Energy resource aggregation is the process of bundling and controlling distributed energy resources such as storage batteries and electric vehicles (EVs) to adjust the balance between power supply and demand.
As Japan promotes renewable energy as the main power source, there are various benefits including securing necessary adjustment capacity, economic benefits for resource providers, and reducing electricity costs through optimal control.

At Eneres, we have been working on developing aggregation technology and schemes focused on low-voltage resources such as household storage batteries and EVs, which are expected to expand in the future among distributed energy resources. Through activities such as demonstration projects we have conducted so far, we believe that EVs are resources that can respond well when connected to charging equipment, and depending on future adoption, could potentially be utilized as main adjustment capacity. However, we have also identified challenges: response rates tend to be low at 50-70% because control is impossible unless charging cables are connected, and to utilize them as adjustment capacity, it is necessary to constantly know the location and status of vehicles. One solution to resolve these challenges and further expand the use of EVs for adjustment capacity is “EV wireless power transfer.”

Wireless power transfer refers to transmitting electrical energy without physically connecting charging cables. It is attracting attention as technology that eliminates the use of wires and batteries while enhancing the mobility, convenience, and safety of electronic devices. If EVs, which are “mobile storage batteries,” can be wirelessly charged, the scope of their utilization as storage batteries will greatly expand.

In this fiscal year’s WG activities, we will examine operational methods and regulations for incorporating wireless power transfer-compatible EVs into energy resource aggregation businesses that are already in practical use, such as providing adjustment capacity to the supply-demand adjustment market (Figure 1). Furthermore, from next fiscal year onward, we plan to pursue new business models created through individuals, companies, and regions sharing EV information and collaborating (Figure 2).

Eneres will work on the WG activities in cooperation with Wireless EV Alliance full member companies, contributing to the development of EV wireless power transfer social infrastructure and the achievement of stable power supply and a decarbonized society.

[About the Wireless EV Alliance]

Improving EV convenience and efficient use of power infrastructure are considered key to strengthening countermeasures against global warming. To solve these challenges and promote the introduction and industrial development of EV wireless power transfer, which is expected to become a promising form of social infrastructure, various sectors of industry, academia, and government need to collaborate and work on various examinations and external activities that contribute to adoption promotion, institutionalization, standardization, and commercialization. The Wireless EV Alliance was established as a venue for cooperation between private companies and research institutions, and as a contact point connecting administrative agencies and industry.
