Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] The invention provides a battery and its control method and electronic equipment. The battery does not need an external heating device in a low temperature environment, and only needs to heat the tab 3, the positive tab 1, the negative tab 2 and the negative heating tab through the positive electrode of the battery. 4. It can heat the positive electrode and negative electrode of the battery without increasing the volume of the battery. The intern...

Abstract

The invention discloses a battery, a control method thereof and an electronic device. The battery comprises a positive tab, a negative tab, a positive heating tab, a negative heating tab and a heatingcircuit, the first end of the positive tab and the first end of the positive heating tab are connected with a positive plate of the battery, and the second end of the positive tab and the second endof the positive heating tab are connected with the heating circuit. The first end of the negative tab and the first end of the negative heating tab are connected with a negative plate of the battery,and the second end of the negative tab and the second end of the negative heating tab are respectively connected with the heating circuit. The battery can be heated through the positive and negative plates in the battery, and the battery can be heated without adding other external heating devices, so that the problem that the service life of the battery is shortened or the charging speed is lowerwhen the temperature is too low is solved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a battery, its control method and electronic equipment. Background technique [0002] Lithium-ion battery is a secondary battery (that is, rechargeable battery), which mainly relies on lithium ions to move between the positive electrode and the negative electrode. It has the advantages of high energy density and no memory effect, and is widely used in various fields. However, due to some characteristic limitations of lithium batteries, the requirements for the environment are relatively strict when charging. When the ambient temperature is low, the activity of lithium ions is low. Depositing metallic lithium on the negative electrode graphite reduces the battery life and increases the expansion rate. Therefore, in order to ensure the life of the battery, it is necessary to reduce the charging current when charging under low temperature conditions, but reducing the charging current wil...
