The automotive industry continues to be a hotbed of patent innovation. Activity is driven by continuous monitoring of battery parameters such as temperature, gas level, voltage, and current, which can warn the system of any anomalous, or even emergency, conditions. Early detection of faults or malfunctions will help prevent explosions and fires in the battery pack. The activity is also driven by the growing importance of technologies such as reset circuits and power management systems. 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 Batteries in automotive: battery emergency protective circuits.   Buy the report here.

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. 

Battery emergency protective circuits is a key innovation area in batteries  

When the battery voltage falls below the lockout threshold, the circuit monitors the voltage of a Li-Ion battery and disconnects the load to prevent deep discharge. A vehicle that runs on batteries runs the risk of being completely discharged if it is stored in a semi-discharged state. 

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 battery emergency protective circuits. 

Key players in battery emergency protective circuits – 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’.
