Lowest installation effort by integrating into existing EDUs
Lowest package size and weight
Flexible drivetrain power levels with the ULTEVATE EDU
Introduce 800 V EV systems without infrastructure barriers
While the infrastructure for electric vehicles is mostly limited to 400 V DC charging, the HV+ powertrain systems are on the rise. Our technology allows an easy transition toward high-power EVs.
Lower overall implementation & production costs
The integrated solution proved to reduce costs for the overall solution compared to other options on the global market by up to 30%, reducing additional on-costs in mass production.
Highest power scalability with the platform approach
The flexible system is engineered to meet even the most advanced performance needs of any customer – from mid-range to high-power applications in hypercars.
High-performance & endurance racing cars
Unprecedented lightness of vehicles paired with limitless charging and increased range
Everyday driving with full confidence of charging being available just like fueling
Trucks & buses
800 V architecture single and double-deck buses or light and heavy-duty trucks can be charged everywhere for optimal short & long-term operations
How is the function realized within the drive system?
During the charging mode: Using a high input voltage (800 V DC) compatible inverter with the operating range between 550 V DC and 900 V DC a direct charging to the battery can be guaranteed. The EDU for enabling booster function is using motor as inductance, inverter switches as a power electronics stage and additional 400 V DC filter and junction box to form a link between 400 v charging station and 800 V battery system.
During the driving mode, inverter drives the motor in DC/AC mode. The 3-L inverter topology allows 800 V with additionally minimized switching losses and maximum ASM efficiency.
The booster function allows 150 kW charging even if the Electric Drive Unit ist rated for 120 kW continuous power.
