Up until now, most electric vehicles have used a voltage of 400-volts for the drive. Only a few battery-powered premium models and sports cars have an 800-volt architecture. The E-GMP electric car platform from the Hyundai Motor Group, which was presented just a few weeks ago, also works at a voltage of 800-volt. This brings several advantages for drivers of electric vehicles: For example, the doubled voltage significantly shortens the battery’s charging time. Depending on capacity, it should be possible to charge the battery to 80 percent in less than twenty minutes, depending on battery capacity. In addition, the 800-volt electrical system enables a higher power output. It also significantly improves the efficiency of the electric drive.
Eleven new electric models with 800-volt technology by 2025
Vitesco Technologies uses semiconductors made from silicon carbide for the 800-volt inverter, which significantly increase the efficiency. This technology is the only way to harvest the full potential of the high-voltage architecture while at the same time providing maximum efficiency.
With the new E-GMP platform, Hyundai Motor Group is underlining its intention to launch a total of 23 battery-powered models by 2025, 11 of which will be exclusively battery-powered, and to sell more than one million vehicles in this drive category worldwide.
For Vitesco Technologies, the major order for the 800-volt inverter is confirmation of the electrification strategy that it has been pursuing up until now and underlines the pioneering approach as a supplier of choice for e-mobility solutions. The company is therefore pushing ahead with the development and optimization of other central components for electric vehicles based on 800 volts – from DC/DC converters to battery management right through to charging systems.
