The invention discloses a temperature protection device for a battery pack of a new energy vehicle, which includes a battery pack, an induction device and a backup motor. The two sides of the battery pack are respectively provided with an induction device, and the battery pack and the induction device are arranged on On the base, the backup motor is connected to two induction devices through an overload protection device, and a contactor is provided on the side of the induction device close to the battery pack. The device can prevent the battery pack from burning and exploding due to continuous heating due to continuous energization, and solves the problem that the general battery pack cannot automatically power off at high temperature, resulting in the battery pack burning and exploding due to continuous heating.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a temperature protection device for a battery pack of a new energy vehicle. Background technique [0002] In order to ensure the mileage of new energy vehicles, large-capacity battery packs are often used for battery life. The battery pack will release heat during charging and other work projects. If the heat generated during the charging process of the battery pack is not released in time, thermal runaway will occur, resulting in battery packs. Spontaneous combustion or even explosion, therefore, a battery thermal management system is installed on the battery pack to cool the battery when the temperature of the battery pack is too high. [0003] In many cases, the combustion and explosion of the battery pack is a continuous process. Due to problems such as battery short circuit, the battery temperature continues to rise. The battery thermal management sys...
