Air-cooled air-conditioner system for plug-in hybrid power bus battery cooling

Abstract

The invention discloses an air-cooled air-conditioner system for plug-in hybrid power bus battery cooling. The air-cooled battery cooling air-conditioner system adopts engine linkage continuous refrigeration and idling intelligent starting and stopping intermittent refrigeration technology, an air-conditioner controller collects the battery core body temperature and logically compares the battery core body temperature with a set value to execute related actions of an air conditioner, the continuous refrigeration during engine linkage and the intermittent refrigeration mode during idling intelligent starting and stopping of the air-conditioner system are achieved, and the plug-in hybrid power energy-saving mode is not damaged as much as possible and the energy consumption of the whole bus is lowered as much as possible while the battery cooling requirement is met. A plurality of air door execution mechanisms and a plurality of temperature sensors are adopted, a battery bin exhaust system is integrated, switching of two circular modes of an air inner loop and an air outer loop is achieved, a battery bin and a passenger region are completely isolated, and the minimum power consumption of the whole bus is achieved while the requirement for battery cooling is met.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioners, in particular to an air-cooled plug-in hybrid electric vehicle battery cooling air conditioner system. Background technique [0002] At present, as traditional energy becomes more and more scarce in our country, climate warming and environmental pollution are also becoming increasingly prominent. The country and the world are looking for sustainable development strategies, looking for renewable energy, and alleviating the energy crisis. Therefore, the new energy industry is also emerging. In order to implement the deployment and requirements of the State Council on cultivating strategic emerging industries and strengthening energy conservation and emission reduction, the central government has arranged special funds and issued a series of policies and standards on subsidies for new energy vehicles to support the development of the new energy vehicle industry. improve dramatically...

AI Technical Summary

Problems solved by technology

At present, the plug-in hybrid electric vehicles on the market use air-conditioning cold air from the passenger area to cool the battery, which often needs to increase the cooling load of the air-conditioning, increase the cost of the vehicle, and have low market competitiveness; in addition, the design of the air connection between the battery compartment and the passenger area , is not in compliance with safety regulations, and the market development prospects are limited; and in some areas where the climate temperature is not high, customers often do not install air conditioners in the passenger area considering the cost issue, and the cooling problem of the battery will be difficult to solve at this time
