Problems solved by technology
[0004] However, the existing fixed-frequency control method cannot control the water flow of the cooling pump in real time according to the heat dissipation requirements of the generator system, so the efficiency is low; at the same time, the setting of an independent controller is not convenient for directly collecting the temperature information of the generator system, which leads to The response is slow, which directly affects the cooling effect of the cooling pump

The invention discloses a cooling system for a generator for a stroke increasing hybrid vehicle and relates to the technical field of vehicles. The cooling system for the generator for the stroke increasing hybrid vehicle comprises a cooling loop and a cooling pump controller, wherein the cooling loop is provided with a cooling pump, and the cooling loop passes across the generator and a generator controller so as to cool the generator and the generator controller; the cooling pump controller is integrated in the generator controller so as to control the cooling pump to work in a variable frequency mode. The cooling pump controller is integrated at the position of the generator controller, so that relevant information in a generator system can be collected timely, and thus a cooling control response speed can be improved; the cooling pump is controlled to work through variable frequency, the cooling fluid flow can be controlled in real time according to heat dissipation requirements of the generator system, so that the generator is in an optimal working state, and thus working efficiency is effectively improved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a cooling system for a generator of a range-extended hybrid electric vehicle. Background technique [0002] With the increasingly serious energy crisis, people urgently need to find new energy to replace traditional energy. At present, in the field of vehicles, range-extended hybrid vehicles have become the development trend of new energy hybrid vehicles. Among them, among the evaluation indicators to measure the pros and cons of the generator system of the range extender, efficiency, reliability and life occupy an important position, and the generator cooling system has a great influence on the efficiency, reliability and life of the generator. [0003] At present, the cooling system of generators mostly uses independent controllers for fixed-frequency control to cool the generators. In this way, the efficiency, reliability and life of the generators can be improved to a certa...
