Development of 140 kW High Performance Integrated Electric DriveProduct Platform

The self-developed 140 kW high-performance automotive electric drive system is the breaking through achievement in a series of cluster technology innovation,such as the design of high-integration low-cost electric drive,design of high-performance motor and inverter,design of high inverter efficiency and vehicle jitter suppression motor control strategies,design of high-safety,high-reliability and high-robust electric drive,and clustered technology innovation of automated calibration and testing.As a result the specific power of the motor is increased to 4.1 kW/kg,the power density of the inverter is increased to 35 kW/L,the total weight of the 3-in-1 electric drive system is reduced to 78 kg,and the maximum efficiency is up to 93%;the cost is reduced by 33.5%compared with the previous generation of discrete systems,the purchase cost of a 3-in-1 system reduced by 24.3%compared with the purchased competitive products in the same period;the functional safety level achieves ASIL-C;and the operating life is up to 500000 km.The comprehensive technical and economic indicators are in the advanced level of the industry.Electric drive systems are widely equipped with X40 EV,E01 and other mainstream models for brands of Bestune and Hongqi for mass production applications.
