Problems solved by technology

[0002] At present, the engine torque controllability of ordinary fuel vehicles is low and the high-efficiency zone is narrow. In order to improve the efficiency, although the gearbox is used to adjust the torque and speed to make the engine work in the high-efficiency zone as much as possible, the efficiency is still very low.

Description

technical field [0001] The invention relates to an electric drive system, in particular to a 100kW electric vehicle drive system for pure electric vehicles. Background technique [0002] At present, the engine torque controllability of ordinary fuel vehicles is low and the high-efficiency zone is narrow. In order to improve the efficiency, although the gearbox is used to adjust the torque and speed to make the engine work in the high-efficiency zone as much as possible, the efficiency is still very low. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a 100kW electric vehicle driving system with good torque controllability, high efficiency, high energy density, large driving force and reliable operation. [0004] The purpose of the present invention is achieved through the following technical solutions: 100kW electric vehicle drive system, which includes a vehicle controller, an electronic ...
