According to GlobalData’s Technology Foresights, which uses over one million patents to analyze innovation intensity for the automotive industry, there are 300+ innovation areas that will shape the future of the industry.

V2X-energy storage is a key innovation area in energy storage

V2X-energy storage refers to the integration of vehicle-to-everything technology with energy storage systems. V2X enables vehicles to communicate with various infrastructure and energy systems, while energy storage systems store and manage electrical energy. By combining these technologies, vehicles can not only use energy from the grid to charge their batteries, but also supply excess energy back to the grid or other connected devices. This enables bidirectional energy flow and enhances the overall efficiency and flexibility of energy management in transportation and power systems.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 30+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of V2X-energy storage.

Key players in V2X-energy storage – a disruptive innovation in the automotive industry
