Problems solved by technology

[0002] In the existing range-extended electric vehicles, the range extender and the power battery are separated from each other, and the two are only connected to each other through the power line, so they cannot help each other in the low temperature environment in winter, especially the power battery. Both the range extender and the range extender need a long time to warm up when the ambient temperature is extremely low
In the prior art, there is no method for preheating the engine by heating the power battery and by using the power battery to heat the engine

Abstract

The invention provides a heat exchange system for an engine and a power cell, a control method and an automobile. The heat exchange system for the engine and the power cell comprises an external charging connector, a second heater, a second heat exchanger, a first heat exchanger, a first heater, a control switch and a controller. The second heater and the second heat exchanger are attached to the power cell. The first heat exchanger is connected with the engine through a pipeline and connected with the second heat exchanger through a pipeline. A heat exchanger switch is arranged between the first heat exchanger and the second heat exchanger. The first heater is attached to the first heat exchanger. The control switch is connected with the external charging connector, the power cell, the first heater and the second heater. The controller judges whether the engine and the power cell need to be heated or not according to the temperature of the engine and the temperature of the power cell, a power supply device for heating the engine and the power cell is selected according to the working state of the automobile, waste heat utilization of the engine is achieved, and meanwhile mutual heating of the engine and the fuel cell is achieved.

Description

technical field [0001] The invention relates to the field of heat exchange between an engine and a power battery, in particular to a heat exchange system, a control method and an automobile for an engine and a power battery. Background technique [0002] In the existing range-extended electric vehicles, the range extender and the power battery are separated from each other, and the two are only connected to each other through the power line, so they cannot help each other in winter low temperature and other environments, especially the power battery. Both the range extender and the range extender need a long time to warm up when the ambient temperature is extremely low. In the prior art, there is still no method for warming up the engine by heating the power battery and by using the power battery to heat the engine. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a heat exchange system between...
