Specific embodiment
In order to allow those skilled in the art to more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention
It is further elaborated.
A kind of lithium ion battery, lithium battery include battery core, shell, control circuit, and the control circuit includes module one
Whether U1, two U2 of module, three U3 of module, four U4 of module, one real-time detection lithium ion battery state of module, judge lithium ion battery
It overcharges, over-discharge, super-high-current charge and discharge, module two is issued instructions to according to lithium ion battery state, module two is wrapped
Power MOS field effect transistor is included, the instruction that receiving module one issues accordingly is switched on or off the circuit of battery charging and discharging, mould
Block three includes NTC, and real-time detection battery temperature, module four includes encryption chip, is encrypted to lithium ion battery, encryption chip
It is DS28E15 chip, encryption chip is single line communication.
A kind of encryption method of lithium ion battery, comprising the following steps:
S1: before battery assembly, by 64 identity codes, key is formed by SHA256 algorithm for encryption, key is burnt to and is added
Close chip, and 64 identity codes are uploaded into cloud server, before 64 identification code encryptions with battery information, manufacture
Information and test information are bound, and upload the data to cloud server, and every piece of chip is merely able to one secondary key of burning；
S2: when assembly battery, mainboard is connected with battery, and the data of mainboard downloading cloud server authenticate battery, is authenticated
Whether the key of burning meets the requirement of Encryption Algorithm in encryption chip, does not meet, and mainboard cannot identify battery, meet, and leads
Plate identifies battery success, carries out in next step；
S3: setting station carries out mainboard and battery is one-to-one is bound, and the identity code of mainboard is first uploaded to cloud and is taken
It is engaged in device, it is corresponding with the identity code of battery, test item is set and determines mainboard and battery binding success, it, will be electric after binding success
Pond ID, mainboard sequence number, binding information upload to cloud server, and test item refers to the identity code and cloud server of mainboard
The mainboard identity code of record is consistent.
After mainboard and battery binding success, when more renewing battery, mainboard downloads the latest data of cloud server, to new
Battery is authenticated, and judges whether there is burning key in new battery, and it is not then that whether burning key, which meets the requirement of Encryption Algorithm,
New battery authentication failure is then new battery authentication success, the information that upload mainboard has been replaced to cloud server, new battery and master
Plate carries out new binding, detects whether new battery and mainboard match with data in cloud server, and otherwise interface prompt is bound
It is unsuccessful, it is then binding success.
After mainboard and battery binding success, when more renewing mainboard, battery is unbinded with old master's plate, the identity of new mainboard
Identification code uploads to cloud server, detects battery and whether new mainboard information matches with cloud server information, otherwise electric
Chi Yuxin mainboard not can be carried out new binding, be, battery and new mainboard carry out new binding, and battery and old master's plate unbind, refer to
It is that the corresponding old master's plate identity code of battery is deleted in cloud server.
User is in use if replace privately or reequip battery, and mobile phone will be unable to identification battery, and user must make
One-to-one binding is carried out with quality battery, and by quality battery and cell phone mainboard, and uploads data to cloud cloud server,
Guarantee that cell safety is reliable.
Cloud server sets battery and real time monitoring battery service condition, if mobile phone and battery make
With circut breaking in the process, has occurred, the behaviours in service such as power cut-off information can also be recorded and upload to cloud server, cloud by mobile phone
Each battery of server tracks carries out life-span management to battery, specifically, the user data area setting of server beyond the clouds
Battery carries out time management later, such as: setting battery 8 years, 1 hour (renewal frequency) * 24(mono-
It) * 365 days (1 year) * 8 years (projected life)=70080 hour=0x111C0 (hexadecimal), it only need to be in user data area
Middle this time of storage, after mainboard normal use one hour, the value of successively successively decreasing, if zero, battery terminates, i.e.,
It is not available replacement battery core also.
Lithium ion encryption method of the application based on encryption chip DS28EL15 is not only applicable in mobile phone terminal, is also suitable
In PC power source, Medical Devices, base station power etc..
Symmetric key of the application based on DS28E15 chip, the SH-256 algorithm of two-way authentication is more difficult to crack, peace
Overall coefficient is higher, this battery encryption method is applied on battery of mobile phone, effectively prevented privately replace, reequip battery this
Phenomenon guarantees the safe and reliable of battery.In addition, because battery identity identification code is dispatched from the factory in chip with regard to burning, and uploaded to
Cloud server can utilize this feature in the manufacturing process of battery, and before battery factory, all related manufacture letters are equal
It can be achieved to bind and upload to cloud server with battery identity identification code, be able to know that the manufacturing process and related ginseng of battery
Number, is conducive to the guarantee of quality, while can prevent rejected product from largely flowing out with each battery using state of real-time tracing.
Above-described embodiment is only wherein specific implementation of the invention, and the description thereof is more specific and detailed, but can not
Therefore limitations on the scope of the patent of the present invention are interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these obvious alternative forms are equal
It belongs to the scope of protection of the present invention.
