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.
Reconfigurable batteries is a key innovation area in batteries
Reconfigurable batteries refer to electrical storage systems that incorporate multiple series-connected electrochemical cells. These batteries are designed to balance the voltage of individual cells to optimize their performance and extend their lifespan. The balancing process involves discharging or charging specific cells based on their state of charge levels to equalize the voltage distribution across the battery pack.
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 reconfigurable batteries.
Key players in reconfigurable batteries – 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’.
