Innovation HighlightsCRRC's fifth-generation pure electric drive assembly integrates ten components (functions) in depth, including motor/electronic control/reducer/DCDC/OBC/PDU/VCU/PTC/EVCC/dTCS. It features CRRC's latest 800V high-efficiency oil-cooled electric drive technology and employs advanced technologies such as self-developed SiC, 0.1mm silicon steel, power module, miniPIN, magnesium alloy, and a dry oil pan. This results in characteristics like high integration, compactness, high efficiency, and lightweight design. It meets the power demands of medium to large pure electric front/rear-wheel drive and range-extended rear-wheel drive systems.
Innovative Highlights:
1.Ultra-small envelope, achieving the functional integration of multi-in-one products within a small volume.
2.Ultra-high efficiency. The efficiency under the CLTC driving cycle is 93.5%, which can increase the driving range of the whole vehicle with the same battery capacity.
3.Ultra-high power density. The weight of the multi-in-one electric drive assembly is comparable to that of the existing three-in-one electric drive assembly, providing assistance for the lightweighting of the whole vehicle.
4.Deeply integrated design of the housing, featuring high overall stiffness and excellent NVH (Noise, Vibration, and Harshness) performance.
