Thermal management lies at the heart of EV INNOVATION

Cooling strategies are evolving to meet the needs of tomorrow's improved EVs.

At the heart of innovations that have powered EV range and performance improvements lies the pursuit of efficiency. Today's electric drivetrains convert over 85% of a battery's electrical energy into mechanical energy. By comparison, internal combustion engines (ICEs) convert less than 40% of their fuel's chemical energy into mechanical energy.

As a result of this greater efficiency, we have seen major gains in electric motor performance, with today's motors operating at up to 25,000 rpm compared to the 15,000 rpm common ten years ago. So, what's driving this increase in efficiency? As with any complex system, there are several variables at play: optimized winding configurations, improvements in magnet layout and materials, and better integration between components. However, one of the major heroes of EV efficiency improvements has been thermal management technologies.
