According to GlobalData’s Technology Foresights, which uses over 619,000 patents to analyse innovation intensity for the automotive industry, there are 290+ innovation areas that will shape the future of the industry.
FEV leak current detection is a key innovation area in electric vehicles
Single-phase circuits are tested for leakage current to the ground by clamping the phase and neutral conductors. Any current that flows to ground will be the quantity being measured. All three-phase conductors are clamped together to test three-phase circuits.
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 90+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of FEV leak current detection.
Key players in FEV leak current detection – a disruptive innovation in the automotive industry
‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.
