Bosch starts manufacturing inverters and electric motors to support electric vehicle production with 800V technology

Bosch’s official website shows that Bosch has begun producing new powertrain solutions based on 800V technology to increase charging speed. The new inverter uses silicon carbide (SiC) semiconductors for improved energy efficiency; the 800V motor version offers increased power density, a more compact design and reduced weight

This site noticed that the 800V inverter uses silicon carbide chips. Carbon atoms are introduced into the crystal structure of ultrapure silicon, improving the semiconductor's conductivity. In power electronics, energy loss in the form of heat is reduced by approximately 50%.

The 800V version of the Bosch motor, now in mass production, is characterized by 830N·m torque and 460kW output power. Thanks to the I-type needle bar winding, the efficiency, compactness and production automation level of the motor can be further improved.

The power density of the 800V version of the motor is increased by 35%, reaching 60 kW per liter, while providing a torque density of 105N·m per kilogram, which means that the maximum efficiency of the motor reaches 98%
