Unique advantages

The compact 800V iDM offers high integration and efficiency, and covers power requirements from 160kW to 300kW with peak wheel torque up to 5500Nm. The power module for the 800V SiC inverter uses BorgWarner's proven double-sided water-cooling Viper module technology, with reduced semiconductor size and increased efficiency. With the proven application of the patented Viper, higher reliability and adaptability are ensured. The high-efficiency high-voltage hairpin motor and oil cooling system design ensure the competitive performance and stable output of the electric drive system.

The current system has achieved ASIL C defined by the ISO 26262 standard and is fully compatible to be upgraded to ASIL D. The software is also cyber security functional. In terms of electric motors, the 800V High Voltage Hairpin (HVH), has a compact design with an outer diameter of 220mm and a maximum speed of over 20,000 rpm. Thanks to the scalable and innovative design, the HVH with its high-power density can achieve high power output in a compact packaging space.

Application

e-Drive system in the electric vehicle

Prospect

800 V enables to design more flexible solutions to optimize powertrain systems, providing more options, including longer mileage or smaller battery pack, super fast charging station will be smaller, lighter and cheaper cables, and more energy recovery during braking to further extend mileage.
