The automotive industry continues to be a hotbed of patent innovation. Activity in vehicle battery cooling is driven by increasing demand for electric and hybrid electric vehicles (HEVs), and growing importance of technologies such as two-phase, direct liquid, microchannel, and spray systems to enhance performance, durability, and safety of electric vehicle (EV) and HEV batteries. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: vehicle battery cooling.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.
300+ innovations will shape the automotive industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over one million patents, there are 300+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, integrated multi-motor drivetrains, electric power steering (EPS), and post-collision handling are disruptive technologies that are in the early stages of application and should be tracked closely. Variable compression engines, V2V distance monitoring, and turbocharger shaft bearings are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are kinetic energy recovery system (KERS) and plasma-jet ignition, which are now well established in the industry.
Innovation S-curve for the automotive industry
Vehicle battery cooling is a key innovation area in automotive
Vehicle battery cooling refers to the process of regulating the temperature of the battery in electric vehicles to improve its performance, efficiency, and lifespan. It involves the use of cooling systems and heat exchangers to dissipate excess heat generated during battery operation and maintain optimal temperature conditions for safe and reliable operation.
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 vehicle battery cooling.
Key players in vehicle battery cooling – 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’.
