Problems solved by technology

[0003] (1) The existing air-conditioning system for hybrid electric vehicles only heats or cools the compartment, and does not combine with temperature management of other components (such as power batteries, drive motors, engines, etc.);
[0004] (2) The existing hybrid electric vehicle temperature management system cools down the power battery, drive motor, and engine through only the radiator of the water tank, the cooling efficiency is low, and it is greatly affected by the ambient temperature;
[0005] (3) When the existing hybrid electric vehicle starts the engine in an extremely low temperature environment, it is prone to severe piston wear and even fracture of the piston connecting rod.
[0006] (4) The existing hybrid vehicle temperature management system has fixed pipelines and a single working mode, making it difficult to select an appropriate working mode according to temperature changes

Abstract

The invention provides a multi-mode temperature management system of a hybrid electric vehicle. The multi-mode temperature management system comprises an air conditioning system, a power battery temperature management system, a driving motor temperature management system and an engine temperature management system, wherein communication and disconnection among the air conditioning system, the power battery temperature management system, the driving motor temperature management system and the engine temperature management system are controlled through pipelines and valves. The multi-mode temperature management system is advantaged in that power battery temperature management modes are dynamically switched according to the real-time temperature of a power battery, driving motor temperature management modes are dynamically switched according to the real-time temperature of a driving motor, and engine temperature management modes are dynamically switched according to the real-time temperature of an engine, temperature management of multiple modes is achieved, the temperature management modes are more flexible, energy utilization efficiency is higher, and temperature control is more stable.
