Bosch started producing inverters & EVB Motors on 800V technology

Bosch’s official website shows that Bosch has begun production of a new powertrain solution based on 800 V technology, which will enable faster charging. The 800V version of the inverter is based on silicon carbide (SiC) semiconductors, which improves energy efficiency; the 800V motor version improves the power density, adopts a more compact design and reduces the weight.

The 800V inverters use silicon carbide chips, in which carbon atoms are introduced into the crystal structure of ultrapure silicon to improve the semiconductor’s electrical conductivity. In power electronics, energy loss in the form of heat is reduced by about 50%.

The 800V version of the Bosch motor, which is now in mass production, is characterized by a torque of 830 N・m and an output power of 460 kW. Thanks to the I-type pin-bar winding, the motor’s efficiency, compactness, and production automation can be further increased.

In terms of power-to-weight ratio, the 800V version offers a 35% increase in power density to 60 kW per litre, while also delivering a torque density of 105 N・m per kilogram, which means that the motor has a maximum efficiency of 98%.
