Problems solved by technology

[0003] Existing battery packs for automobiles will generate heat during use, that is, during charging and discharging, which will cause the temperature of the battery pack to rise. Therefore, a heat sink is usually installed on the battery pack. Limited, when the battery pack generates more heat due to the increase in load, the heat dissipation capacity cannot be adjusted accordingly, resulting in an increase in the temperature of the battery pack, causing danger, and because the battery pack is installed at the bottom of the car frame , so it is vulnerable to vibration and shock caused by car bumps during driving, which will damage the battery pack after a long time, reducing safety and service life. In view of this, we propose an adaptive protection device for car battery packs and its Instructions

Abstract

The invention relates to the field of automobile batteries, and in particular to a self-adaptive protection device for an automobile battery pack and a using method thereof. The device includes a protective shell, the battery pack is arranged in the protective shell; cooling liquid for cooling the battery pack is filled in the protective shell; a buffer protection mechanism is arranged on the inner bottom surface of the protection shell; the buffer protection mechanism is connected with the bottom of the battery pack; a touch control mechanism is arranged on the buffer protection mechanism; anadjusting mechanism is arranged on the outer side of the protective shell; the touch control mechanism can make contact with the adjusting mechanism in an abutting and buckling mode, a first heat exchanger and a second heat exchanger which are used for conducting circulating cooling on cooling liquid and an audible and visual alarm with an alarm function are fixed to the side wall of the protective shell, and the adjusting mechanism is electrically connected with the first heat exchanger, the second heat exchanger and the audible and visual alarm. According to the self-adaptive protection device for the automobile battery pack and the using method of the self-adaptive protection device, the cooling effect on the battery pack and the safety guarantee effect on the battery pack are improved.

Description

technical field [0001] The invention relates to the field of automobile batteries, in particular to an adaptive protection device for automobile battery packs and a method for using the same. Background technique [0002] A large part of new energy vehicles use batteries as the energy storage power source and release the electric energy through the batteries to provide driving force for the car, so as to make the car run. In the existing electric vehicles, multiple batteries are used to form a large-capacity battery pack, also called The battery pack is usually installed at the bottom of the frame of the car, and the battery pack is cooled by liquid cooling. [0003] Existing battery packs for automobiles will generate heat during use, that is, during charging and discharging, which will cause the temperature of the battery pack to rise. Therefore, a heat sink is usually installed on the battery pack. Limited, when the battery pack generates more heat due to the increase in...
