Description

Technical Field

[0001] The present application relates to the field of thermal management technology, and in particular to a thermal management system of a vehicle and the vehicle. Background Art

[0002] The current automotive industry is committed to researching ways to reduce vehicle energy consumption to adapt to the increasingly severe energy crisis. This includes developing new energy vehicles and new heating technologies, but these are often costly.

[0003] The reduction in battery range during winter driving has always troubled OEMs. The low-temperature insulation of the battery, the heating of the battery, the heating of the passenger compartment, and the low-temperature starting of the engine increase the vehicle's energy consumption. Therefore, it is necessary to improve the energy utilization rate of the battery and passenger compartment heating so that the vehicle has a longer range with the same amount of electricity and fuel, making it more competitive. Especially for hybrid electric vehicles in cold and extremely cold areas, battery insulation, battery heating, passenger compartment heating needs and engine cold start are more valued. Low-temperature engine starting and battery insulation rely on high-voltage battery packs to be heated at high voltage multiple times to maintain the battery pack temperature to ensure that the engine can start normally. A large amount of electricity is consumed in severe cold weather. If the vehicle is in a low-temperature state for a long time, the vehicle will lose power and cannot be used normally. Even if the vehicle is fully fueled, it still cannot be used normally. The vehicle can only be started after being plugged in for charging, causing user complaints, or relying on the plug-in power preservation strategy. Vehicle air conditioning and heating in low-temperature environments are completed by engine coolant heating and air conditioning electric heater (PTC) heating. Extra electricity is consumed when heating the medium, and the electrical energy is converted into heat energy. Extra electricity is required to ensure the comfort of the passenger compartment after the vehicle is refrigerated in severe cold seasons. Summary of the Invention
