Abstract

The invention discloses a thermal runaway protection system for an electric vehicle battery with an automatic alarm function, and relates to the technical field of battery thermal runaway protection systems; in order to improve heat dissipation capacity; it specifically includes a protective case and a positioning seat for installing a battery main body, the protective case It is a cylindrical structure, and the outer wall of the protective case is provided with evenly distributed air vents; the bottom of the battery body is installed in the positioning seat, and the outer wall of the bottom of the positioning seat is fixed to the inner wall of the bottom of the protective case by screws; the outer side of the battery body The wall is provided with cooling grooves distributed equidistantly; the inner wall of the bottom of the protective shell is installed with an annular water tank through a support column. In the present invention, by setting up structures such as an annular water tank, a circulation pump, and a heat transfer box, when the battery body generates heat during operation, the heat transfer plate is used to exchange heat with the battery body, and the circulation pump can extract the cooling liquid in the annular water tank, and through the circulation Tubes and heat transfer plates circulate to facilitate heat dissipation.

Description

technical field [0001] The invention relates to the technical field of battery thermal runaway protection systems, in particular to an electric vehicle battery thermal runaway protection system with an automatic alarm function. Background technique [0002] Battery thermal runaway means that when the battery is charged at a constant voltage, the current and battery temperature undergo a cumulative enhancement and are gradually damaged. In order to ensure the safety of use, battery thermal runaway protection systems are often required in electric vehicle battery applications; Although the current battery thermal runaway protection system can meet certain usage requirements, it generally only dissipates heat through air cooling or water cooling, and the heat dissipation capacity needs to be improved. [0003] After retrieval, the Chinese patent application number is CN201820853152.X, which discloses a fuel cell vehicle and its cooling system. The cooling system includes a cool...
