The power industry continues to be a hotbed of patent innovation. Activity is driven by declining battery prices and total costs of ownership, increases in fleet electrification, and the enactment of emissions targets, and growing importance of technologies such as electric vehicle charging systems. In the last three years alone, there have been over 656,000 patents filed and granted in the power industry, according to GlobalData’s report on Electric vehicles in power: DC fast charging EVs. Buy the report here.
According to GlobalData’s Technology Foresights, which uses over 70,000 patents to analyze innovation intensity for the power industry, there are 40+ innovation areas that will shape the future of the industry.
DC fast charging EVs is a key innovation area in electric vehicles
An on-board charger is located inside an EV and converts AC power into DC power before distributing it to charge the vehicle’s battery. DC fast charging bypasses the on-board charger and directly charges the battery, significantly reducing the time required to charge an EV. Charging times vary depending on battery size, dispenser output, and other factors, but most vehicles can get an 80% charge in about or under an hour using most currently available DC fast chargers.
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 80+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of DC fast charging EVs.
Key players in DC fast charging EVs – a disruptive innovation in the power industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
