Which Technologies Will Drive the Battery Electric Vehicle Industry?: A Keyword Network Based Roadmapping

Battery Electric Vehicles (BEVs) have unraveled as a potential solution to address the global pollution crisis and alter the global oil trade structure. With various evolving technologies and improving the efficiency of BEV s, it is imperative to analyze the developmental trends and identify the technologies at the cutting edge that will shape the development of the future BEV industry. Using text mining of patent abstracts, we develop keywords-based technology maps for technologies converging in a BEV. The resulting maps reveal the development of various battery chemistries with potential BEV applications. This evidence-based approach will help policymakers at the macro level and decision-makers at the micro level to identify and forecast the futuristic realm for investments in the proximate technologies for competence development and manage technology-related decisions for acquisition and exploitation.
