Problems solved by technology

However, at present, the pure electric driving motor of the plug-in electromechanical coupling system heats up quickly and the high temperature lasts for a long time.
The motor cooling system fully suitable for plug-in hybrid electric buses in summer is still not perfect, which restricts the industrialization of plug-in hybrid electric buses

Abstract

The invention discloses a hybrid cooling system and method for a plug-in new-energy bus motor. The system comprises an ECU, a motor water-cooling device and a motor air-cooling device. The motor water-cooling device and the motor air-cooling device are respectively provided with a temperature acquisition device and a temperature control device. The ECU is connected with the temperature acquisition devices and the temperature control devices. The hybrid cooling system and method for the plug-in new-energy bus motor are based on the characteristics of pure electric driving and hybrid power driving of plug-in hybrid power, and the working state of a water-cooling system and the working state of an air-cooling system are controlled according to working condition modes and motor temperature. In this way, the drive motor can work at the optimal temperature under any working condition, the usage range is wider, the reliability of a finished bus can be greatly improved, and the purposes of lowering consumption and reducing emissions are achieved.

Description

Technical field [0001] The present invention relates to the technical field of automobile manufacturing, in particular to a hybrid cooling system and a cooling method for a plug-in new energy passenger car motor, specifically a system and method for adjusting the working temperature of the motor by using two sets of independent heat dissipation systems to work together. Background technique [0002] In recent years, the world oil market prices have fluctuated sharply. Governments of various countries have adjusted their own energy strategies. In addition, vehicle exhaust emissions have caused serious pollution of urban air. With the rapid economic development, the country has paid more and more attention to energy conservation and environmental protection. A wave of research and development of electric vehicles is emerging at home and abroad. [0003] Plug-in hybrid buses have the characteristics of hybrid buses and pure electric buses. Like pure electric buses, they have an indepe...
