Contactless charging is a key innovation area in electric vehicles
Contactless charging refers to the process of transmitting electrical power from a charging station to an electric vehicle or electronic device without the need for physical contact between the charging station and the device. This is achieved by using magnetic fields to transfer energy wirelessly, providing a more convenient, efficient, and safe charging experience compared to traditional wired charging methods.
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 contactless charging.
Key players in contactless charging – 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’.
