Abstract

The invention discloses a power battery group of an electric vehicle. The power battery group comprises a battery group shell and a plurality of battery modules arranged in the power group shell, and also comprises heat management parts integrated in the power group shell, wherein the heat management parts comprise a rear evaporator, a battery heater and a battery fan; the setting positions of the rear evaporator, the battery heater and the battery fan in the battery group shell need to meet the conditions that cold air formed by the rear evaporator and hot air formed by the battery heater are accelerated to circulate under the action of the battery fan and flow through all the battery modules. The power battery group disclosed by the invention has the advantages that closed design is adopted, so that the dustproof and waterproof grade is high; the heat management parts are arranged inside, and air ducts are simple in design and high in temperature consistency; on the basis of the power battery group, a charging management system and a heat management system are small in occupied space, have no heat loss in the conveying process and are low in cost; and the control integration level is high.

Description

technical field [0001] The invention relates to the field of electric vehicle heat management, in particular to an electric vehicle power battery pack and its charging management system, and an electric vehicle air conditioner and a heat management system for the power battery pack. Background technique [0002] As one of the core components of electric vehicles, the battery faces the disadvantages of safety hazards in low-temperature charging and life decay in high-temperature discharge. Therefore, the battery temperature control range directly determines the safety performance, service life and driving range of the battery. The power battery pack of an electric vehicle is designed by stacking a large number of single cells, and its charge and discharge performance is worse than normal in a low temperature environment. When the battery temperature is lower than a certain value, the power battery cannot be directly charged (such as lithium iron phosphate low cannot be charge...
