- The company claims that in terms of power-to-weight ratio, this delivers 35% more power density, at 60 kilowatts per litre
Bosch has started the production of new powertrain solutions for electric vehicle solutions based on 800-volt technology. The company clams this will make recharging faster, and will also help increase range.
Based on silicon carbide semiconductors, in the 800-volt variant of the electric motor, Bosch has increased the power density. It says that 400-volt solutions have become widely established as the industry standard. “With the same current but double the voltage, twice as much power can now be transmitted.”
Its press release read, “This modification allows for thinner cables, which saves on space, weight, and copper. As a result, the inverter is more compact and powerful. With a 400-volt onboard network, the maximum charge power at charge spots that are powerful enough is 250 kilowatts. With 800 volts, twice this is possible in theory.”
The standout features of the 800-volt variant of the Bosch electric motor now going into volume production are 830 Nm torque and 460 kilowatts output. Further the company claims that in terms of power-to-weight ratio, this delivers 35% more power density, at 60 kilowatts per liter.
“Bosch is upping the voltage in electromobility. Our 800-volt technology is the next step toward more powerful electrical powertrains and shorter recharging times,” says Ralf Schmid, the executive vice president responsible for electrification in Bosch’s Powertrain Solutions division.
