A new invention can help increase the range of electric vehicles (EVs) while reducing their overall cost.
According to foreign media reports, researchers at the Trivandrum Institute of Engineering (CET) in India have proposed a digital modulation scheme for controlling electric vehicle motors to replace the analog scheme currently in use.
, (Photo source: CET), the control scheme was invented by Professor Biji Jacob of the Department of Electronics and Communications Engineering at CET and Jeeshma Mary Paul, a researcher in the Department.
Currently, this method and system for providing variable speed control for motors has been patented.
, The patented invention is a discontinuous digital pulse code modulation scheme.
Compared to traditional pulse width modulation schemes used to control electric vehicle motors, this scheme can operate with less equipment and has better performance.
Effective control of motors in electric vehicles is important to help optimize performance, maximize efficiency, extend battery life, ensure safety and improve the overall driving experience.
Biji said: “The newly invented modulation scheme is inherently discontinuous and can reduce switching losses, thereby saving overall power and extending battery range.
“, According to the researchers, successful integration of this invention into electric vehicle motors can reduce battery load by up to 20%, thereby improving cruising range.
Currently, the limited cruising range of electric vehicles is one of the main factors deterring many potential buyers.
Biji said: “This invention is actually simpler than traditional simulation systems.
This will also help reduce the cost of electric vehicle controllers, thereby reducing overall costs.
“, The research began six years ago and a patent application was filed in 2021.
Now, researchers look forward to working with electric vehicle manufacturers to put their inventions into industry applications.
