Abstract

Disclosed is a battery thermal management system based on an oil-electricity hybrid electric vehicle. By means of a natural aspiration principle of an internal combustion engine, air sucked into a combustion chamber flows through a power battery box to cool a power battery, high temperature waste gas introduced into the combustion chamber is made to flow through the power battery by means of the working principle of a waste gas recycling system to heat the power battery, and finally the actual temperature of the working power battery is controlled within the best working temperature region. The system can achieve control according to the difference between the current actual working temperature and the ideal working temperature of the power battery on the condition that the power, oil consumption and discharge performance of the internal combustion engine are not affected, so that cooling or heating treatment is performed on the power battery. The using performance of the whole power battery pack is improved, and the service life of the whole power battery pack is prolonged; thermal runaway of the battery is avoided, the power battery safety accident rate is lowered, and the battery thermal management system is low in cost, efficient and capable of saving energy.

Description

technical field [0001] The invention relates to a battery thermal management system based on an oil-electric hybrid vehicle. Background technique [0002] In recent years, the number of motor vehicles in my country has grown rapidly, and their exhaust emissions have become one of the most important sources of pollution affecting urban air quality, seriously affecting and restricting the sustainable development of cities. Therefore, the new energy vehicle research project has been included in the "863" major scientific and technological projects by the state. Although pure electric vehicles have outstanding environmental protection advantages, the research on their industrial development is still in its infancy, limited by key technologies such as fuel cells, and the problems of poor power, short driving range and high cost have not been resolved. As a transitional product and a compromise solution between traditional fuel vehicles and pure electric vehicles, hybrid vehicles...
