Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar popularization under the situation of intension of the present invention.Therefore the present invention is not subjected to the restriction of following public concrete enforcement.
Embodiment one
With reference to figure 2.
S110: obtain the parameter value of described battery, described parameter value is used to judge whether described battery uses first current charges.
This step is specially: obtain the parameter value of battery earlier, for example obtain the actual full capacity of battery (fullcharge capacity).The actual full capacity of battery can obtain from battery by bus (SMBUS).In addition, actual full capacity can measure battery by bus, in addition can also utilize other method well known to those skilled in the art.
S120: call one and be used to judge the standard information whether described battery charges with first electric current.
This step is specially: the design capacity (Design capacity) that calls battery, design capacity can obtain from battery by bus (SMBUS), because design capacity has just configured when battery dispatches from the factory, for example design capacity is 3000C, electric weight when battery is full of in the time of so initial just is 3000C, and design capacity can read the Default Value acquisition of battery by bus.Along with the use of battery, the capacity of battery can descend, thereby can not reach design capacity when battery is full of, but reaches actual full capacity, and for example actual full capacity is 2000C, and at this moment the battery electric weight that is full of electricity just is 2000C.
S130: handle described parameter value and described standard information, produce an object information.
In the present embodiment, after obtaining design capacity and actual full capacity, the magnitude relationship of design capacity and actual full capacity relatively, for example when described actual full capacity be less than or equal to described design capacity 90% the time, the generation charge command.
Usually battery specification according to battery when dispatching from the factory is that battery has been set charging current, the pairing charging current of standard in advance just, but this charging current is bigger usually, because the inventor studies the back and finds that charging current is big more, it is serious more that battery capacity reduces, therefore work as actual full capacity less than the design capacity particular percentile, as 90% o'clock, select the low current charge pattern, just first electric current of Xuan Zeing is less than the pairing charging current of standard in advance of battery, usually corresponding scope of the pairing charging current of standard in advance, value arbitrarily in this scope just, 0.6C-0.8C for example, if the pairing charging current of standard in advance of battery is 0.7C-0.8C, this first electric current can be 0.6C, 0.5C, 0.35C or the like, if the pairing charging current of standard in advance of battery is 0.6C-0.7C, this first electric current can be 0.5C, 0.35C, if the pairing charging current of standard in advance of battery is 0.8C, this first electric current can be 0.7C, 0.6C or the like, can slow down reducing of battery capacity like this.
Preferably, when described actual full capacity be less than or equal to described design capacity 90% the time, the ratio of described actual full capacity and described design capacity is more little, first electric current is more little.
Preferably, described parameter value also comprises the residual capacity (Relative state of chargeremianing capacity) of battery, the residual capacity of described battery was before battery charge, existing electric weight in the battery, electric weight was 2000C when for example battery was full of, and the electric weight after use a period of time in the battery becomes 1000C, at this time if to battery charge, the battery electric quantity of Ce Lianging is 1000C just so, and just residual capacity is 1000C.Because charging current is more little, charging interval is long more, if what therefore charging current was provided with is too small, then can lose time, therefore after obtaining residual capacity, utilize the magnitude relationship of actual full capacity and design capacity, and residual capacity calculates first electric current, what make time cost and battery capacity reduces to reach optimum closing most.Therefore under actual full capacity and the definite situation of design capacity ratio, the residual capacity of battery is more little, and then first electric current is more little.If for example actual full capacity is less than 90% of design capacity, determine to adopt the low current charge pattern earlier, first electric current is less than 0.7C, judge residual capacity then, big more then first electric current of residual capacity is more little, and first electric current that uses when for example residual capacity is the 70%-90% of actual full capacity is less than 0.35C; First electric current that uses when perhaps residual capacity is for 50%-70% is 0.35-0.5C; First electric current that uses when perhaps residual capacity is for 30%-20% is 0.5C-0.7C, by that analogy, certainly, above-mentionedly just illustrates, and also can adopt other mode to determine first electric current of little current-mode.
In addition, can show the relation of actual full capacity and design capacity, the user can select first electric current under the low current charge pattern, thereby determines first electric current, for example can select by keyboard.For example when oneself being arranged, can select the sufficient time less current less than the pairing charging current of standard in advance of battery, charging at a slow speed, thus reduce influence to battery capacity.In the present embodiment,, therefore when battery capacity descends to some extent, reduce reducing of battery capacity, protected the useful life of battery by reducing charging current because the more little influence to battery capacity of charging current is more little.
S140:, utilize described first electric current that described battery is charged according to described charge command.
Be specifically as follows: with the current conversion of output is first electric current, and charging voltage is provided simultaneously, and described charging voltage can be the normal voltage of man of Battery Plant setting, and this step can be utilized method well known to those skilled in the art.Utilize described first electric current and charging voltage to be battery charge then.
Embodiment two

Preferably, when the life cycle number of battery was counted greater than described during cycle, the life cycle number of described battery was big more, and first electric current is more little.
Preferably, described parameter value also comprises the residual capacity of battery, and under the situation that described battery life cycle number is determined, the residual capacity of battery is more little, and first electric current is big more.
Embodiment three
Comprise embodiment one described method among this embodiment, be not all with embodiment one in addition:
Before obtaining the parameter value step of described battery, also comprise: to battery discharge.
Be specially in the present embodiment: when battery condition is bad, for example actual full capacity is less than 50% of design capacity, whether prompting and inquiry user select discharge mode, carry out capacity resuming, when the user agrees to carry out capacity resuming, remind the user to insert and do not extract battery, finish up to recovery process.When selecting discharge mode, and detect battery the time, send the order battery and carry out low discharging current.By adopting in the method that is battery discharge, can recover the battery that battery capacity has reduced like this, its capacity is increased.The step of battery discharge can find in charging that perhaps battery condition is bad after being full of electricity.
