Auto Supplier Bosch to manufacture Silicon Carbide chips that can extend the range of EVs

An article written by Eric Walz for FutureCar – German automotive supplier Robert Bosch is launching production of silicon carbide (SiC) automotive chips, a move that can make electric vehicles more efficient, thereby increasing range. Silicon carbide has benefits over traditional silicon chips, including better conductivity and cooling performance in high temperature environments.

German automotive supplier Robert Bosch is launching production of silicon carbide (SiC) automotive chips, a move that can make electric vehicles more efficient, thereby increasing their range, Reuters has reported. 

Silicon carbide has benefits over traditional silicon chips, including better conductivity and cooling performance in high temperature environments. The SiC chips are well suited for use in electric vehicles. 

SiC semiconductor material can operate at higher voltages with lower leakage current. SiC transistors and diodes can also function at higher frequencies at a higher temperature, without compromising reliability. SiC chips have fewer crystal defects compared to silicon-based materials, making them highly suitable for power chargers in electric, hybrid, and fuel-cell vehicles. 

“Silicon carbide semiconductors bring more power to electric vehicles. For motorists, this means a 6% increase in range,” Bosch board member Harald Kroeger said on Monday.

SiC-based power semiconductors are used in the on-board charging units in electric cars and the technology is well suited for the traction inverter of electric vehicles. In a electric vehicle, the purpose of the traction inverter is to convert DC current from the electric vehicle’s battery pack to AC current to be used in the electric motor to drive the vehicle’s propulsion system… Full article
