Thank you, Mr. Air, a netizen of CTOnews.com, for your clue delivery! CTOnews.com Sept. 1, Bosch official website shows that Bosch has begun to produce a new powertrain solution based on 800V technology, which will make charging faster. The 800V version of the inverter is based on silicon carbide (SiC) semiconductors and improves energy efficiency; the 800V motor version increases power density, uses a more compact design and reduces weight.

CTOnews.com noted that the 800V inverter uses silicon carbide chips, and carbon atoms are introduced into the crystal structure of ultra-pure silicon, improving the conductivity of semiconductors. In power electronic equipment, the energy lost in the form of heat is reduced by about 50%.

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

In terms of power-to-weight ratio, the 800V version of the motor increased its power density by 35% to 60 kW per liter, while providing a torque density of 105 Nm per kilogram, meaning the highest efficiency of the motor was 98%.
