Japan Liquid Cooled EV Charging Cable Market (2025-2030)

The study involved four major activities in estimating the current size of the liquid cooled EV charging cable market. Exhaustive secondary research was done to collect information on the market, the peer market, and the parent market. The next step was to validate these findings, assumptions, and sizing with the industry experts across value chains through primary research. The top-down and bottom-up approaches were employed to estimate the complete market size. Thereafter, market breakdown and data triangulation processes were used to estimate the market size of segments and subsegments.

Secondary Research

In the secondary research process, various secondary sources, such as company annual reports/presentations, press releases, industry association publications [publications of electric vehicle manufacturers, International Energy Agency (IEA), Alternative Fuel Data Centre (AFDC), European Alternate Fuels Observatory (EAFO), Federal Transit Administration (FTA), Regional Transportation Authority (RTA), country-level vehicle associations and trade organizations, and the US Department of Transportation (DOT)], EV-related magazine articles, directories, technical handbooks, World Economic Outlook, trade websites, government organizations websites, and technical articles, company websites, whitepapers, databases, and articles from recognized associations and government publishing sources, were referred to. The secondary data was collected and analyzed to arrive at the overall market size, which was further validated by primary research for an extensive commercial study of the liquid cooled EV charging cable market.

Primary Research

Extensive primary research was conducted after acquiring an understanding of this market scenario through secondary research. Several primary interviews were conducted with market experts from the demand- and supply-side OEMs (in terms of component supply, country-level government associations, and trade associations) and component manufacturers across three major regions, namely Asia Pacific, Europe, and North America. Approximately 40% and 60% of primary interviews were conducted from the demand and supply sides, respectively. Primary data was collected through questionnaires, emails, LinkedIn, and telephonic interviews. In the canvassing of primaries, we have strived to cover various departments within organizations to provide a holistic viewpoint in our report. Brief sessions with highly experienced independent consultants were conducted to reinforce findings from primaries after interacting with industry experts. This, along with the in-house subject matter experts’ opinions, led to the findings, as described in the remainder of this report.

In the primary research process, various primary sources from the supply and demand sides were interviewed to obtain qualitative and quantitative information for the report. The primary sources from the supply side included industry experts, such as Vice Presidents (VPs), marketing directors, technology and innovation directors, and related key executives from various key companies and organizations. The primary sources from the demand side included end users, such as Chief Information Officers (CIOs), consultants, service professionals, technicians and technologists, and managers at public and investor-owned utilities.

Market Size Estimation

The bottom-up methodology was followed to estimate the size of the liquid cooled EV charging cable market by application. It involved the identification of the number of ultrafast 1, ultrafast 2, and megawatt charging points from country-level associations and paid databases. Also, the penetration for liquid cooled cables was derived through discussions with industry experts, while the other two segments were considered as default users of liquid cooled cables. Cable power capacity was then derived based on the setup of ultrafast 1, ultrafast 2, and megawatt chargers. Pricing was mapped by cable power capacity from secondary sources and validated through discussions with industry experts. The number of cables was multiplied by the average selling price to derive the market value. Market size by volume and value was then aggregated to arrive at regional and global market size estimates.

Data Triangulation

More than 25 companies were mapped as providers of liquid cooled EV charging cables. Company-specific revenue for EV charging cables was mapped after discussions with industry experts. Supply-side analysis was conducted to identify the cooling technology segment and understand its revenue contribution. Market penetration for cooling technology applications was mapped at the regional level through secondary research, with insights validated by industry experts. Segmentation by cooling technology application was calculated by multiplying the market size by penetration rates. A similar approach was applied for segmentation by cable length, cable diameter, and jacket material.
