Description
Technical field
The present invention relates to a kind of charging device, relate in particular to a kind of intelligent activated lithium battery charging device.
Background technology
Because behind the lithium cell charging, general rechargeable battery power has the anti-time-consuming of longer standby, thereby much be subjected to charger for example mobile phone, mobile computer, digital camera, rechargeable electric drill etc. recently, one after another with lithium battery as discharging and recharging power supply, the endurance after yet lithium battery charged after use a period of time at every turn can progressively descend, and we are called cell degradation at custom.The cell degradation main cause is an electrode through behind the repeatedly chemical reaction steady in a long-term, the effective area that the electrode surface deposition causes electrode to carry out chemical reaction reduces, and the equiva lent impedance that the deposition of electrode surface has just formed input, output raises.
Battery is when charging; the charging current Ic of direct current can go up in input impedance (Ri) and produce a pressure drop Vi (Vi=Ic*Ri); (this protection circuit is normally based on the detecting voltage circuit for the protection circuit of inside battery; added that electric weight blocked defencive function; this also claims with detecting voltage circuit representative below circuit) or charger on the voltage that detected of detecting voltage circuit will be V=VB+Vi (VB is the real voltage of battery); the impedance that is caused because of deposition also forms a capacitance characteristic Cr; its equivalent electric circuit is Ri and connects Cr; Vi can be maintained a period of time because of capacitance characteristic when charging current Ic has just stopped; the battery full charging 4.15V why Here it is wears out; take down charger and become 4.0V, stop the reason that discharge voltage becomes 3.7V again after putting a little electric current.
Output impedance (Ro) can be influential when discharge, but if degree of influence will be very little under the low discharging current, if battery be subjected to the chronic of the very long just little current work of charger (as mobile phone) stand-by time, output impedance (Ro) increases little to the endurance degree of influence of product.
So the cell degradation influence is the increase of input impedance (Ri) as the main cause of the product endurance of mobile phone, Ri is healed big Vi also more greatly when charging process, and the battery essence voltage VB (VB=V-Vi) behind the full charging is just more not enough.
Only mobile phone is having on the market more than billions of in use at present; its lithium battery uses all can meet aging process; battery of mobile phone 2 years just can the sensed cell capacity decline; some second-rate battery capacity time decline are faster; just more feel; the user is often because of endurance deficiency behind the cell degradation; change battery and feel unfortunate because of expensive again; replace fast sometimes even because of the mobile phone style; the related cell type money of original mobile phone that makes stops production; be not easy to buy the new battery that desire is replaced; have to also connect whole the abandoning of mobile phone purchases on a barter basis; for the whole world; battery to scrap quantity surprising; and the related people of making form the custom of abandoning charging appliance easily; increase the pollutional load of unnecessary defective work to environment; this is everybody puzzlement; if the real full charging of battery that can these are aging; and in each charging process; battery progressively can be activated; this can prolong the useful life of battery greatly, to the individual who uses; earth resource; the environmental protection of the earth will be very helpful.
The charger for mobile phone that picture trip at present fills wants cube to be easy to carry about with one for a short time; make its function very simple; transformation charger (also claiming AC to DC circuit) falls just like grafting civil power 110V socket; or as the socket that lights a cigarette of electricity in the grafting car; the direct current buck charger of computer USB supply socket (also claiming DC to DC circuit); do voltage by the built-in protection circuit of lithium battery again; temperature; the protection of current anomaly; and do full charging control and show by mobile phone itself; in addition; for battery charge; its charging interval also is an emphasis; trip's charger is in order to shorten the charging interval; so after transformation and step-down; also all be to battery charge with direct current; can be very high to new battery DC charging efficient; be unique shortcoming be exactly that each charging does not have mobilizing function, cause battery to use a period of time after, the endurance after recharging can die-off very undesirable.
Summary of the invention
Technical problem underlying to be solved by this invention is; overcome the above-mentioned defective that prior art exists; and provide a kind of intelligent activated lithium battery charging device; can avoid pole plate to hoard greatly; crystallization and the input that raises; output impedance; even this charging modes of Lao Hua battery; can full charging except still; also can be when each charging; the hoard thing of crystallization on pole plate eliminated some reduction impedances; in this way through repeatedly charging; also aging battery progressively can be activated, allow various battery of mobile phone all can insert the universal charger of usefulness, directly the battery itself to various mobile phone charges; reach the battery overvoltage protection; avoid the charging interval long, it can will be built in the program in the microprocessor of control circuit, needn't increase any hardware circuit and just can reach.
