Embodiment Construction

[0023] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0024] A lithium ion battery, the lithium battery includes a battery cell, a casing, and a control circuit, and the control circuit includes a module one U1, a module two U2, a module three U3, and a module four U4, and the module one detects the state of the lithium ion battery in real time, and judges whether the lithium battery Whether the ion battery is over-charged, over-discharged, or over-currently charged and discharged, an instruction is sent to module 2 according to the state of the lithium-ion battery. Module 2 includes a power MOS field effect transistor, which receives the instruction from module 1 and opens or cuts off the battery charging and discharging accordingly. In the loop, module three includes NTC, which detects the battery temperature...

Abstract

The present invention provides a lithium ion battery. The lithium ion battery comprises a battery cell, a shell and a control circuit, the control circuit comprises a module I, a module II, a module III and a module IV; the module I detects the state of the lithium ion battery in real time, determines whether the lithium ion battery is overcharged, overdischarged and overlarge-current charged anddischarged or not, and sends a command to the module II according to the state of the lithium ion battery; the module II comprises a power MOS field effect transistor, and receives the command sent bythe module I and correspondingly opens or cuts off a battery charging and discharging loop; the module III comprises an NTC and detects the temperature of the battery in real time; and the module IVcomprises an encryption chip and encrypts the lithium ion battery. According to the invention, the lithium ion battery can be encrypted, the battery and the mobile phone mainboard are bound in a one-to-one correspondence manner, and the safety and reliability of battery use are ensured.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a lithium ion battery and an encryption method thereof. Background technique [0002] With the rapid development of the electronic field, lithium-ion batteries are more and more widely used, and their safety has been paid more and more attention by the public. However, ordinary lithium-ion batteries are easy to be copied. The specified materials, even the core part of the battery, are fake and abused. Such counterfeit batteries have great potential safety hazards. In addition, lithium-ion batteries are commonly used as a power source for mobile phones. Users can replace or modify the batteries at will during the use of mobile phones, which not only affects the service life of the batteries, but also poses a great safety hazard during the use of mobile phones. [0003] In order to solve the above problems, it is necessary to set a unique identification for the ...
