Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and the embodiments,
The present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are only explaining this hair
It is bright, it is not intended to limit the present invention.
The present invention provides a kind of battery, including the battery core module for storing electrical energy, the protection for protecting battery core module
Module, the communication module for exchanging information with outside, protection module are electrically connected with battery core module；Further include real-time clock mould
Block, real-time clock module are electrically connected with communication module.
Since real-time clock module is arranged in battery, battery thus can not be in the terminal set, still may be used
To be kept for date and Hour Minute Second do not lose；The host of mobile terminal is not had to design memory battery at the same time, reached saving and moved
The purpose of the inner space of dynamic end host.
It is described in detail below in conjunction with realization of the embodiment to the present invention.
As shown in Figure 1, being the schematic diagram of battery provided by the invention, which includes the battery core mould for storing electrical energy
Block, the protection module for protecting battery core module, the communication module for exchanging information with outside, protection module and battery core module
It is electrically connected；Real-time clock module is further included, real-time clock module is electrically connected with communication module；So real-time clock module is set
In the battery, under general normal use battery is low in mobile terminal report voltage and automatic shutdown after, still have inside it
There is certain residual electric energy, at this moment battery is taken out, the residual electric energy of battery still can maintain the work of real-time clock module,
Still maintain its time remembered；Do not charge for a long time afterwards except non-battery is used, at this moment since the residual electric energy release of battery is dry
Only, the time of memory can lose, and real-time clock is returned to the initial time of default setting setting；So real-time clock module is set
Put in battery, it is possible to the space of mobile terminal is saved, when real-time clock module being set in the battery certainly, it is necessary to brilliant
Oscillation body device is also provided with battery, so being preferably integrated into chip, while real-time clock module and communication module is integrated
Onto chip, so to batch production and electromagnetic compatibility advantageously.
As shown in Fig. 2, battery has three output pins, wherein the first pin 1 is anode, the cathode electricity with battery core
Connection；Second pin 2 is battery cathode, is electrically connected by protection module with the anode of battery core；3rd pin 3 passes through communication module
It is electrically connected with real-time clock module；Present most of batteries all use three pin configurations, in order to keep compatibility, existing three
On the basis of pin battery, it is smaller that increase real-time clock module can make the renewal of product design cost；When battery is installed to movement
When in terminal, anode and anode are powered to mobile terminal, and real-time clock signal can be transmitted everywhere by the 3rd pin 3
Device is managed, such mobile terminal-opening is it is seen that the correct time.
The temperature measurement module for measuring battery temperature is further included, temperature measurement module is electrically connected with communication module；General thermometric mould
Block is made of thermo-sensitive resistor, can be so worth to by providing voltage to thermo-sensitive resistor from the electric current for flowing through thermo-sensitive resistor
Corresponding battery temperature information, when detecting battery temperature, real-time clock signal still can continue to read, this is because measurement
DC voltage is provided to thermo-sensitive resistor during battery temperature, can be by removing DC voltage easily the real-time of pulse
Clock signal and temperature detection signal are distinguished from.
Further include the electric power detection module of the storage electricity for detecting battery core module, electric power detection module and communication module
It is electrically connected；The 3rd pin can be multiplexed in a cell of this invention, after electric power detection module is provided with the battery, Ke Yijing
Communication module is transmitted by BIF (Battery Interface, battery interface) or other self defined interfaces to processor.
Further include for battery being identified encrypted identification module, identification module is electrically connected with communication module；When
In battery be provided with identification module after, can through communication module by BIF (Battery Interface, battery interface) or its
His self defined interface transmits checking information to processor.
Protection module is to carry out overcharge and/or overdischarge and/or the mould of overcurrent and/or short-circuit protection to battery core module
Block；In fig. 2, protection module is by protection chip controls, by being turned on and off battery core module anode between second pin 2
Field-effect tube protects battery, and protection module is used to prevent battery core module overcharge, overdischarge, overcurrent and short trouble, this
It is relatively reliable that sample can make battery work, and battery life can also increase.
Battery core module is liquid lithium ionic cell battery core module or polymer lithium ion battery electric core module；Liquid lithium ion
Battery cell module uses liquid electrolyte, and polymer lithium ion battery electric core module is solid electrolyte；Liquid lithium ion
The heat dissipation effect of battery battery core is better than polymer lithium ion battery electric core；But its electric energy savings amount is not as good as polymer Li-ion battery
Battery core, therefore battery core module can be selected according to actual conditions.
The cathode of battery is cobalt acid lithium or nickel cobalt manganese or LiFePO4；Small, but the environment easy to pollute of cobalt acid lithium；Nickel cobalt
Manganese is not easy to explode, safe, but expensive；LiFePO4 is environment-protecting and non-poisonous, but expensive；These can be according to product
Actually select.
The anode of battery is graphite；Graphite has conductivity high, and crystallinity and layer structure are good, to the diffusivity of lithium ion
Can be good, therefore graphite is used as battery cathode.
Temperature measurement module is positive temperature coefficient resistor or negative temperature coefficient resister；Positive temperature coefficient resistor overload capacity is strong, but
Power stability is poor；Negative temperature coefficient resister high sensitivity, but it is easy to aging；Therefore need flexibly to be selected according to actual conditions.
In short, the present invention has saved button cell, so as to reach increase by the way that real-time clock module is set into battery
The purpose of mobile terminal inner space, make mobile terminal is designed with more allowances, this is increasingly miniaturized sum aggregate in mobile terminal
The today constantly increased into degree, there is good realistic meaning.
Accordingly, the present invention also provides a kind of mobile terminal, the mobile terminal to include the battery.The battery is institute
State mobile terminal power supply.
The foregoing is merely the better embodiment of the present invention, it is not intended to limit the invention, it is all the present invention's
All any modification, equivalent and improvement made within spirit and principle etc., should all be included in the protection scope of the present invention.
