Abstract

The invention discloses a spraying type heating and refrigerating integrated safety battery pack. The battery pack comprises a battery box and batteries accommodated in the battery box; and the battery pack also comprises a spraying liquid loaded in the battery box, a sprayer fixed in the battery box, a spraying liquid circulation pipe, a liquid pump connected with the spraying liquid circulation pipe, and a heat exchange system connected with the spraying liquid circulation pipe, wherein the head and tail ends of the spraying liquid circulation pipe are connected with the spraying liquid and the sprayer respectively. On one hand, the battery pack is in a proper use environment, so that a huge amount of heat generated in the operating process of the battery pack can be taken away in time; on the other hand, uniform temperature between the single batteries in the battery pack can be maintained, so that battery pressure difference caused by overhigh temperature difference can be avoided; and therefore, the electrochemical performance and the service life of the battery can be improved and prolonged, and the hidden danger of thermal runaway caused by partial overheating also can be avoided.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a spray heating and cooling integrated safety battery pack. Background technique [0002] In order to alleviate the increasingly serious pollution of the urban environment (especially the atmosphere) and the depletion of non-renewable energy sources, and the increasing harm of global temperature rises, electric vehicles have become a hot topic in the automotive industry. The governments of various countries and domestic and foreign auto companies generally recognize the importance and urgency of the development of the electric vehicle industry. The development of electric vehicles fundamentally solves the best solution to the above-mentioned problems in the automotive industry. The power battery is the source of power for electric vehicles. During driving, the working condition and service life of the battery are not only related to the structure and principle of the ...
