Abstract
The invention discloses a mobile phone emergency charger, and relates to a charger. Pins of an integrated chip (1) of the charger are connected to a charging voltage detection circuit (2), a charging control circuit (3), a charging current detection circuit (4), a charging indication device (5), a battery identification (ID) chip (6), a battery temperature detection device (7), an anomaly detection device (8) and a charging detection controller (9) respectively. The mobile phone emergency charger has high circuit integration level and very small volume, totally can realize small and delicate appearance design, has practical internal function and low cost, and does not damage a battery.
Description
Technical field:
The present invention relates to a kind of charger, be specifically related to a kind of emergent charger for cell phone.
Background technology:
Portable type electronic product with battery as power supply.Along with the fast development of portable product, the consumption of various batteries heightens, and develops many novel batteries.The high performance alkaline battery of being familiar with except that everybody, chargeable nickel-cadmium cell, the Ni-MH battery, also have the lithium battery of exploitation in recent years, lithium battery is widely used in various digital products.Better as a kind of function; the communication tool that is convenient for carrying; mobile phone becomes digital product indispensable in the life gradually; that yet people go out to be engaged in is public, during tourism; Shi Changhui forgets or is unwilling to carry heavy charger for mobile phone, perhaps can not find the AC power that can give cell-phone charging in the specific occasion at all.What the charger of mobile phone lithium battery commonly used adopted is constant current pressure limiting charging system, charging current generally adopt about C2----promptly adopt two hours charge rates, adopt the 250ma charging to reach behind the 4.2V constant voltage charge more about two hours such as the 500mah battery." universal mobile phone charger " that nominal can be fit to the 250mah---2500mah battery charge appears in the market, be breakneck in fact, it lacks the detection to battery capacity, adopt fixing output current, for different batteries, not to cause the charging interval long to be exactly to cause current charge, there is certain harm in lithium battery.
Summary of the invention:
The purpose of this invention is to provide a kind of emergent charger for cell phone, its circuit level height, volume is very little, can realize small and exquisite fineness in the appearance design fully, the built-in function practicality, with low cost, and can not damage battery, be the optimal selection of digital product, electric equipment products, office products etc.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it is by integrated chip 1, charging voltage testing circuit 2, charging control circuit 3, charging current testing circuit 4, charge indication means 5, battery ID chip 6, battery temperature checkout gear 7, abnormal detector 8 and charging detect controller 9 to be formed, and each pin of integrated chip 1 is connected to charging voltage testing circuit 2 respectively, charging control circuit 3, charging current testing circuit 4, charge indication means 5, battery ID chip 6, battery temperature checkout gear 7, abnormal detector 8 and charging detect controller 9.
The present invention has increased little electric current preliminary treatment and constant temperature charge mode based on the dc constant voltage mise-a-la-masse method, promptly adopts less current that battery is carried out preliminary treatment at the charging initial stage, and the battery that overdischarge occurs is repaired and protected; Adopt bigger constant current to battery charge then, realize the purpose of quick charge; Adopt constant pressure charging at last, guarantee that battery is full of; In the constant current charge stage, when chip temperature rose to a certain degree, the chip overheating protective circuit was started working.
Circuit level height of the present invention, volume is very little, can realize small and exquisite fineness in the appearance design fully, and the built-in function practicality is with low cost, and can not damage battery, is the optimal selection of digital product, electric equipment products, office products etc.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it is by integrated chip 1, charging voltage testing circuit 2, charging control circuit 3, charging current testing circuit 4, charge indication means 5, battery ID chip 6, battery temperature checkout gear 7, abnormal detector 8 and charging detect controller 9 to be formed, and each pin of integrated chip 1 is connected to charging voltage testing circuit 2 respectively, charging control circuit 3, charging current testing circuit 4, charge indication means 5, battery ID chip 6, battery temperature checkout gear 7, abnormal detector 8 and charging detect controller 9.
This embodiment has increased little electric current preliminary treatment and constant temperature charge mode based on the dc constant voltage mise-a-la-masse method, promptly adopts less current that battery is carried out preliminary treatment at the charging initial stage, and the battery that overdischarge occurs is repaired and protected; Adopt bigger constant current to battery charge then, realize the purpose of quick charge; Adopt constant pressure charging at last, guarantee that battery is full of; In the constant current charge stage, when chip temperature rose to a certain degree, the chip overheating protective circuit was started working.
The circuit level height of this embodiment, volume is very little, can realize small and exquisite fineness in the appearance design fully, and the built-in function practicality is with low cost, and can not damage battery, is the optimal selection of digital product, electric equipment products, office products etc.
