The automotive industry continues to be a hotbed of patent innovation. The industry is experiencing a surge in demand for electric vehicles (EVs), necessitating innovative charging solutions. Dual-voltage charging stations are becoming popular due to their flexibility, efficiency, and futureproofing. They can charge both high-voltage and low-voltage EVs, making them more convenient for owners. Government incentives and regulations, growing demand for EVs, OEM involvement, technological advancements, standardization efforts, and industry collaboration are driving innovation in these charging stations. Dual-voltage charging stations are incorporating four key technologies: modular power conversion systems, GaN semiconductors, dynamic voltage and current control, and vehicle-to-grid (V2G) communication protocols. These systems enable scalable, adaptable, and user-friendly charging for EVs. Modular systems allow for easy maintenance and upgrades, while GaN semiconductors offer higher frequencies and voltages, reducing size and weight. In the last three years alone, there have been over 720,000 patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: dual-voltage charging stations.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.
300+ innovations will shape the automotive industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over one million patents, there are 300+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, multi-spark ignition, integrated multi-motor drivetrains and vehicle auxiliary drives are disruptive technologies that are in the early stages of application and should be tracked closely. Solar range extenders, turbocharger shaft bearings, and multi-lamellar clutches are some of the accelerating innovation areas, where adoption has been steadily increasing. Among the maturing innovation areas are auto-transmission lubrication circuits and electroluminscent vehicle displays, which are now well established in the industry.
Innovation S-curve for the automotive industry
Dual-voltage charging stations is a key innovation area in automotive
Dual-voltage charging stations are arrangements that provide electric energy to track-bound vehicles and road automobiles using an alternating electromagnetic field and electromagnetic induction. The arrangement includes a receiving device with at least one inductance that produces an alternating electric current by electromagnetic induction. The inductance is connected to a rectifier that rectifies the alternating electric current to produce a direct electric current. The arrangement also includes a control device for automatically controlling a switch that results in a short circuit across the inductance.
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 940+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of dual-voltage charging stations.
