Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to a thermal control system for a complete electric vehicle. Background technique [0002] Compared with traditional internal combustion vehicles, electric vehicles have canceled the fuel engine, and cannot use the waste heat of the fuel engine coolant to heat the cabin, so a new heating method must be found. In addition, electric vehicles also add heat-generating components such as battery packs, motors, chargers, etc. that work under high-voltage and high-current conditions, which need to be maintained in the optimal operating temperature range, and must be thermally controlled. [0003] In the prior art, the heating method in the compartment of an electric vehicle mainly adopts an independent heat source, that is, uses PTC (Positive Temperature Coefficient, positive temperature coefficient) heating; or uses a fuel heater to heat with gasoline, kerosene, eth...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned heating methods, if PTC is used for heating, more battery energy will be consumed, which in turn will reduce the mileage of the car

If a fuel heater is used for heating, not only the heating efficiency is low, but it will pollute the environment. At the same time, considering the collision safety of electric vehicles, the layout of the fuel tank is also a big problem

On the other hand, using an independent radiator for the heat-generating components in the electric vehicle not only does not make good use of the heat, but also in the case of high ambient temperature, the cooling effect on the heat-generating components is also poor, and the heat generation cannot be controlled Components operate at optimum temperature
