Technical field
The invention belongs to the lithium battery field, particularly a kind of wireless charging lithium battery.
Background technology
Take portable electronic equipments such as mobile phone, MP3, notebook computers as example, what charge mainly is traditional charger, and an end links to each other with power frequency AC, and the other end connects the rechargeable battery of portable electric appts.This frequently plug damages interface easily, overcharges for a long time can damage the life-span of storage battery even burn out the mobile device mainboard, also can bring simultaneously the danger of electric shock.And because the interface standard disunity, each electronic product has a charger that is complementary with it, has caused so a large amount of wastes, has increased manufacturing cost.Simultaneously, along with informationalized rapidly development, people are more and more higher to the requirement of mobile communication quality and content, the development along with demand of mobile device correlation technique, function from strength to strength the time dominant frequency more and more higher, screen is increasing, power consumption also rises rapidly, it is a general demand that stand-by time grows up to, and existing battery technology is broken through possibility in a short time, so people are to there being strong demand to the relevant device that mobile device charges whenever and wherever possible.
Lithium battery is widely used in mobile phone, digital camera and notebook computer.Make a general survey of the development situation of global lithium battery wireless charging device, electromagnetic induction reception, Charge Management and charging indication are not integrated in the design of one.Traditional lithium battery if will carry out wireless charging, often need to even also need supporting charge management circuit at an external induction coil, causes equipment volume excessive, with electronic product can't be supporting etc. many troubles.
Summary of the invention
The object of the present invention is to provide a kind of integrated wireless charging lithium battery of the reception of electromagnetic induction energy, Charge Management, electromagnetic shielding and charging indication function.
The technical solution that realizes the object of the invention is:
A kind of wireless charging lithium battery comprises induction coil, electromagnetic shielding material layer, rectifying and voltage-stabilizing and charge management circuit, lithium cell core, and wherein, induction coil is positioned at battery bottom, and the electromagnetic shielding material layer is positioned at induction coil top; Lithium cell core is positioned at the battery top; Rectifying and voltage-stabilizing and charge management circuit are between lithium cell core and electromagnetic shielding material layer.
The present invention compared with prior art, its remarkable advantage:
(1) the Charge Management unit is built in whole lithium battery interior, battery can break away from electronic equipment and charge, the a series of requirements of wireless charging to electronic product have been avoided, such as external induction coil, charging circuit and charging indication etc., strengthened the compatibility of wireless charging, conventional wireless charging requirement energy receiving terminal (electronic product) need to the built-in induction coil that matches with self, charging circuit and charging indication etc. in product, increased cost and the design difficulty of electronic product, common electronic product can't carry out wireless charging.Any electronic product now these all is integrated in the lithium battery, so that can carry out wireless charging.
(2) put on the wireless charging flat pad when lithium battery, lithium battery can with charged state, pass through the charging indicated number out such as charge, electric weight has been full of etc.
Below in conjunction with accompanying drawing the present invention is described in further detail.
