Title:
BATTERY ELECTRIC VEHICLE AND ELECTRIC DRIVE POWER SYSTEM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/259518
Kind Code:
A1
Abstract:
Disclosed are a battery electric vehicle and an electric drive power system therefor. The electric drive power system comprises a first electric motor (1), a first gear shift mechanism, a second electric motor (8), a second gear shift mechanism and a system output shaft (11), wherein the first electric motor (1) is connected to the system output shaft (11) via the first gear shift mechanism, and the second electric motor (8) is connected to the system output shaft (11) via the second gear shift mechanism. The range of output rotating speeds and the range of output torques of the electric drive power system are greatly expanded. It can be guaranteed that the first electric motor (1) and the second electric motor (8) are still in an efficient working range when the system is in a high-rotation-speed or high-torque working condition, the working efficiency of the system is improved, the optimal balance between economical efficiency and dynamic performance can be successfully achieved, the problem of the adaptability of the system under all working conditions and road conditions is solved, the power consumption of the whole vehicle is reduced while meeting requirements for the dynamic performance of the whole vehicle, and the operation cost is reduced.
