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.
EV drive planetary gears is a key innovation area in electric vehicles
EV drive planetary gears refers to the gear systems used in EVs with one or more electric motors to transmit power from the motor to the wheels. Planetary gears consist of a sun gear, a ring gear, and planet gears that rotate around the sun gear and mesh with the ring gear, providing a compact and efficient way to achieve different gear ratios.
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 EV drive planetary gears.
Key players in EV drive planetary gears – a disruptive innovation in the automotive 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’.
