Abstract

The invention provides a fuel cell and power cell heat exchange system and a control method. The fuel cell and power cell heat exchange system comprises: a first heater; a first heat exchanger communicated with a fuel cell through a pipeline; a second heater attached to the fuel cell and which is connected with a power cell or an external charge interface; a second heat exchanger and a third heater that are attached to the power cell, wherein the second heat exchanger is communicated with the fuel cell through a pipeline, and the third heat exchanger is connected with the external charge interface; a controller. The controller uses different heating devices to heat the fuel cell and the power cell according to the magnitude of a first temperature of the fuel cell, the magnitude of a second temperature of the power cell and state of charge of the automobile, waste heat of the fuel cell is utilized to heat the power cell and a passenger cabin, and resources are saved.

Description

Technical field [0001] The invention relates to the field of heat exchange between fuel cells and power batteries, in particular to a heat exchange system, control method and automobile for fuel cells and power batteries. Background technique [0002] During the use of electric vehicles in winter, the use of resistance wire PTC heating causes problems such as short cruising range, and the waste heat generated by the fuel cell cannot be reasonably used, resulting in waste of resources. Summary of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a fuel cell and power battery heat exchange system, a control method, and an automobile, so as to realize the utilization of the heat of the fuel cell and help the fuel cell and the power battery to quickly Reach normal operating temperature. [0004] In order to solve the above technical problems, the heat exchange system of fuel cell and power battery provided by the embodim...
