Description
Technical field
The present invention relates to integral new-energy passenger technical field, be specifically related to a kind of temperature-adjusting device and control method of the energy-storage system for integral new-energy passenger.
Background technology
Along with people deepen the attention of environmental problem, integral new-energy passenger especially hybrid power passenger car and pure electric automobile enters into popular sight line gradually.Especially pure electric automobile and pure electric coach, need to use a large amount of electrokinetic cells, not only needs the impact of the installation site of considering the electrokinetic cell of the environment such as heavy rain on pure electric automobile, and the heat dissipation problem of electrokinetic cell is to be also badly in need of one of problem of considering simultaneously.
The method of the heat dissipation problem of the solution electrokinetic cell proposing in prior art is: adopt the air-conditioner wind of introducing passenger compartment to enter the mode of dispelling the heat in the energy-storage system at power battery pack place.The air-conditioner wind of introducing enters cooling in energy-storage system, finally by blower fan, the gas in energy-storage system is discharged.So likely cause the temperature of energy-storage system inside far below the temperature of external environment but still be discharged from, cause the waste of energy.In addition, it is in running order for a long time that this mode requires the air-conditioning of passenger compartment.
Summary of the invention
Technical problem to be solved by this invention is, thereby provides a kind of temperature that can energy-conservationly can regulate well again energy-storage system to make energy-storage system be operated in the temperature-adjusting device of the energy-storage system for integral new-energy passenger in rational temperature range.This device is in particular for regulating the temperature of the energy-storage system that is located at passenger vehicle top.
Technical solution of the present invention is, a kind of temperature-adjusting device of the energy-storage system for integral new-energy passenger with following structure is provided, in particular for regulating the temperature of energy-storage system that is located at passenger vehicle top, comprise the air-conditioning system setting that is independent of passenger compartment accumulation energy air conditioner system, connect the air channel of accumulation energy air conditioner system and energy-storage system and be located at the protective cover outside energy-storage system.
Compared with prior art, the temperature-adjusting device of the energy-storage system for integral new-energy passenger of the present invention has the following advantages.Directly energy-storage system is carried out to temperature adjusting owing to being provided with the accumulation energy air conditioner system that is independent of passenger compartment, regulative mode is easier.Also be not easy the temperature of the air that occurs energy-storage system inside far below the temperature of external environment but still situation about being discharged from, therefore more energy-conservation.In addition, can regulate in real time according to the actual work temperature of energy-storage system, energy-storage system is operated in rational temperature range, this also can extend the working life of energy-storage system.
In one embodiment, the inwall of described protective cover is provided with heat-barrier material, and described heat-barrier material stops the heat of external environment condition to spread in protective cover at external temperature during far above internal temperature; Described heat-barrier material stops the heat in protective cover to spread to external environment condition at external temperature during far below internal temperature.Protective cover is especially in the situation that the very high and external temperature of external temperature is very low, the sun at noon in for example summer is exposed to the sun ambient temperature very high time, or evening in winter, ambient temperature dropped in very low situation, can play in isolating and protecting cover and the effect of ambient temperature.Thereby the temperature in protective cover is remained in relatively reasonable scope; in the time that accumulation energy air conditioner regulates the temperature of energy-storage system; can not only be energy-conservation, and can reduce energy-storage system and be operated in the possibility of extreme temperature, can play a protective role to energy-storage system to a certain extent.
