Gradient heating sheet for power battery of new energy automobile

Abstract

The invention provides a gradient heating sheet for a power battery of a new energy automobile, relates to the technical field of batteries of new energy automobiles, and solves the problems that duston a storage battery cannot be cleaned in a linkage manner and the cleaned dust cannot be automatically cleaned when a heating device is dismounted, temporary storage of heat cannot be realized in the use process, and the problem of heat waste is easily caused. The gradient heating sheet comprises a shell, a storage battery body is installed in the shell, and three heating piece structures are further installed in the shell. A cleaning plate is welded on a heating piece main body, is in contact with the bottom end surface of the inner wall of the shell, and is aligned to the slag discharginghole; the front end face of the cleaning plate is of an inclined structure, so that when the heating piece body is pulled, the cleaning plate can automatically achieve collection of dust cleaned by the cleaning brush, and finally the dust is discharged through the slag discharging holes.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicle batteries, and more specifically relates to a gradual heating sheet for a power battery of a new energy vehicle. Background technique [0002] With the development of the new energy automobile industry, lithium-ion batteries have been widely used. In low-temperature environments, the internal discharge resistance of lithium-ion batteries will increase significantly, resulting in a decrease in their discharge capacity and operating voltage. [0003] For example, the application number: CN201911257412.2, the invention discloses a new energy vehicle power battery gradient heater in the field of new energy vehicle battery structure technology, including a base, the front end of the base is provided with a front fixing plate, and the base The rear end is provided with a rear fixing plate, the top front end of the base is provided with a front mounting plate, the top rear end of the base is p...
