Abstract

The invention discloses a heat control system for a hybrid power or range-extending type electric automobile. A power battery system supplies power to a refrigeration cycle system and a heating cycle system, and a whole automobile controller controls the refrigeration cycle system or the heating cycle system in the mode that the battery temperature and voltage information transmitted by the power battery system is collected through a CAN bus. An electric driving refrigeration cycle system preheats an engine for starting through heat generated by an electric appliance part, and an engine refrigeration cycle system enables the temperature of refrigeration liquid of the heating cycle system to be raised through heat generated after the engine is started. According to the heat control system, effective heat control over each component of the electric automobile is achieved, waste heat of electrical apparatus elements and waste heat of the engine are adopted for improving the heating efficiency of the electric automobile, heat waste is reduced, the energy utilization rate is improved, waste heat of a driving motor or an electric heater system can be used for preheating the engine, the engine burning efficiency is improved, and good control over heating or refrigerating of a power battery package can be achieved.

Description

technical field [0001] The invention relates to the field of thermal control systems for electric vehicles, in particular to a thermal control system for hybrid or extended-range electric vehicles. Background technique [0002] Due to the increasingly serious environmental pollution, the country is now vigorously advocating the development of new energy electric vehicles. However, due to the current short driving range of pure electric vehicles, the development is relatively slow. The advantages of hybrid electric vehicles and extended-range electric vehicles, such as low pollution and long driving range, have taken the lead in realizing mass production and commercialization. [0003] A hybrid (or range-extended) electric vehicle has both the engine system of a traditional vehicle and the motor system of a pure electric vehicle. As a result, the thermal control system of hybrid (or range-extended) electric vehicles should reasonably combine the thermal control systems of t...
