Bosch Readies More Efficient Microchips for EVs
Robert Bosch GmbH says it will begin commercial production next year of significantly more efficient computer chips for electric vehicles.
The microchips, which are made of silicon carbide, are more heat tolerant and electrically conductive than traditional silicon devices. Bosch says the new chemistry, designed for use in an EV’s power electronics, will cut energy loss due to heat by 50% and extend the range of electric vehicles by 6%.
Bosch is making pilot quantities of the new chips for potential customers to evaluate. The supplier predicts its new chip design will begin to appear in EVs by 2023.
Chrysler pioneered the modern-day minivan more than 30 years ago and has been refining and improving that type of vehicle ever since.
