Battery controller 24 can detect the real time electrical quantity of rechargeable battery 23, and sends that information to mobile phone CPU21.Vehicular applications module 22 reads the battery level information in mobile phone CPU21 in real time.Then, battery level information is sent to external equipment data processing module 13 by the data wire 4 in cable 3 by vehicular applications module 22, then is transmitted to interacted system CPU11.
Interacted system CPU11 determines rechargeable battery 23 required charging current value at that time according to the real time electrical quantity of rechargeable battery 23, and by this at that time required charging current value information be sent to charge control module 14.Charge control module 14 controls charging power modules 15 and charges for rechargeable battery 23 with required charging current value at that time.
Required charging current value depended on the real time electrical quantity of rechargeable battery 23 at that time.Fig. 2 shows a kind of exemplary relation therebetween, in figure, abscissa represents the real time electrical quantity (Vol of rechargeable battery 23, unit is the percentage ratio of real time electrical quantity value and battery total capacity), the longitudinal axis represents required charging current value (I, unit is mA) at that time.
When the real time electrical quantity of rechargeable battery 23 is positioned at low electricity interval (such as 0% to 20%), charge with rated charge flow valuve (such as 500mA, it is preferable that constant).When the centrally located electricity interval of the real time electrical quantity of rechargeable battery 23 (such as 20% to 60%), charge with medium charging current value (such as 300mA to 150mA, it is preferred to gradually change, for instance linear change shown in figure).When the real time electrical quantity of rechargeable battery 23 is positioned at high electricity interval (such as 60% to 100%), charge with low charging current value (such as 150mA or 100mA, it is preferable that constant).
It is understood that, interval and the corresponding charging current value of each electricity shown in figure is merely exemplary, it is possible to specifically arrange or adjust (such as judged by interacted system CPU11 and adjust) according to concrete mobile phone (or other moves equipment) model, type of rechargeable battery etc..
In general, for battery of mobile phone, the low electricity section definition of rechargeable battery is lower than one first power threshold.On this threshold value, mobile phone could continue properly functioning.(being namely positioned at low electricity interval) under this threshold value, it is difficult to maybe can not maintain mobile phone and continue properly functioning, mobile phone will enter electricity deficiency pattern.Such as, described first power threshold is the 20 ± 5% of battery total capacity, namely low electricity interval is arranged on real time electrical quantity is 0% to 20 ± 5%, will not must interrupt with rated charge flow valuve (or the high charge current value higher than rated charge flow valuve) for battery charging could maintain the properly functioning of handset program in this interval.Interacted system CPU11 can obtain the model of battery of mobile phone and thereby determine that the standard charging current value of battery.Afterwards, rated charge flow valuve can be set as the standard charging current value of battery by interacted system CPU11.Or, it is also possible to directly rated charge flow valuve is set as that 350mA to 1000mA even arrives 2500mA or 3000mA, for instance 500 ± 50mA.Described high charge current value is higher than described rated charge flow valuve, it is preferable that not higher than 2000mA.Described high charge current value can be constant or adjustable, it will be preferred that in optional multiple current values.
When middle electricity interval between described first power threshold and one second power threshold of the real time electrical quantity of battery, charge with the medium charging current value lower than described rated charge flow valuve for battery；When real time electrical quantity at battery is located higher than the high electricity interval of described second power threshold, charge with the low charging current value lower than described medium charging current value for battery.Described second power threshold is a set point value between described first power threshold and 100% electricity, it is possible to be configured according to specific requirement, for instance, it is possible to choose the intermediate value between described first power threshold and 100% electricity.As an example, described second power threshold is the 60 ± 10% of battery total capacity.
Specifically, it is 20 ± 5% to 60 ± 10% that the middle electricity interval of rechargeable battery may be provided at real time electrical quantity, in this interval, just can maintain the properly functioning of mobile phone (mobile equipment) with medium charging current value for battery charging, and can ensure that the electricity in battery continues to increase (namely the charge volume of battery is more than power consumption).Medium charging current value can reduce along with the increase of real time electrical quantity, for instance linear reduction or step-by-step movement reduce.Correspondingly, medium charging current value can be set as in the scope between the standard charging current value and charging battery flow valuve of battery by interacted system CPU11 based on the model of battery of mobile phone.Or, it is also possible to directly medium charging current value is set as 350mA to 150mA.Medium charging current value changes preferably within the scope of it, for instance reduce along with the increase of real time electrical quantity.
It is 60 ± 10% to 100% that the high electricity interval of rechargeable battery may be provided at real time electrical quantity, can with low charging current value for battery charging until battery is full of in this interval.Correspondingly, interacted system CPU11 can determine the charging battery flow valuve of this battery based on the model of battery of mobile phone, and afterwards, low charging current value can be set as the charging battery flow valuve of battery by interacted system CPU11.Or, it is also possible to directly low charging current value is set as 50mA to 150mA, it is preferred to steady state value, for instance 100mA or 150mA.
