Be used to detect the cell voltage of current charging stage and whether reach the charging upper voltage limit, be judged as when being, the charging current value that described battery is current is adjusted, and described battery is carried out constant current charge with described adjusted electric current, when being judged as not, continue described battery to be carried out first judging unit of constant current charge with current electric current.
Implement the utility model embodiment, have following beneficial effect:
Traditional charging modes to battery is a first constant current constant voltage again, but when charger need charge to dissimilar batteries, elder generation's constant current mode of constant voltage more just is not easy to have realized, the utility model has adopted the mode of multi-stage constant current, make battery charger to charge, improved the compatibility of battery charger dissimilar batteries.
Description of drawings
Fig. 1 is a kind of structural representation of realizing the device of battery charge of the utility model embodiment;
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the utility model embodiment one realizes that the device of battery charge comprises:
Detecting unit 1 is used to detect the magnitude of voltage of current battery;
First judging unit 2 is used to judge whether the cell voltage of current charging stage reaches the charging upper voltage limit, is judged as when being, the charging current value of described battery is adjusted, and when being judged as not, continues with current electric current described battery to be carried out constant current charge.
Described first judging unit 2 further comprises:
The unit 3 that adds up, the number of times that the described charging current biography value that is used to add up is adjusted;
Second judging unit 4 is used to judge that the described electric current that adds up adjusts number of times and whether reach predefined electric current and adjust number of times, when being judged as when being, stops charging process, when being judged as not, with described adjusted electric current described battery is carried out constant current charge;
Setup unit 5 is used to preestablish the number of times that electric current is adjusted.
The utility model embodiment realizes that the device of battery charge also comprises: the 3rd judging unit 6, be used for judging according to the described battery voltage value that detects whether the voltage of described battery reaches the charging lower voltage limit, when judging not, with little electric current described battery is carried out precharge and reach described charging lower voltage limit up to described cell voltage.
During concrete enforcement, be example with a kind of charging process of LI battery, wherein the specification of LI battery is 3.6V1400mAH, and the charging voltage upper limit is 4.15V, and the charging lower voltage limit is 3V.
Charging process is as follows: at first, unit 2 zero clearings add up, detecting unit 1 detects current LI battery voltage value, the 3rd judging unit 6 judges whether the voltage of LI battery reaches charging lower voltage limit 3V, when judging not, with little electric current the LI battery is carried out precharge and be higher than 3V, carry out big electric current constant current charge then up to the LI cell voltage; Be judged as when being, directly carry out big electric current constant current charge, before carrying out big electric current constant current charge, the adjustment number of times that setup unit 5 is set electric current is 3, enter the phase I charging then, wherein, described setting electric current is adjusted the step of number of times and is judged whether to carry out the uninevitable precedence relationship of precharge process, adjusts number of times and also be not counted in electric current by the big electric current constant current charge of precharge little electrorheological.
If the charging current of phase I is 1800mA, wherein the big I of phase I charging current value is set according to actual needs, when charging, detecting unit 1 detects the battery voltage value of current charging stage in real time, first judging unit 2 judges whether described detected magnitude of voltage reaches charging upper voltage limit 4.15V, when being judged as not, continue described battery to be carried out constant current charge with current electric current.Be judged as when being, the charging current value of described battery is adjusted to half or following (900mA) of phase I charging current value, simultaneously, unit 3 electric current that adds up that adds up is adjusted number of times, then electric current adjustment number of times becomes 1,4 of second judging units judge whether the described electric current adjustment number of times (1 time) that adds up reaches predefined electric current and adjust number of times (3 times), is judged as not, with described adjusted electric current (900mA) described battery is carried out the second stage constant current charge.
In the second stage charging process, when first judging unit 2 judges that according to detecting unit 1 detected battery voltage value described detected magnitude of voltage reaches charging upper voltage limit 4.15V, then adjust half or following (250mA) that charging flow to the second stage charging current value, simultaneously, unit 3 electric current that adds up that adds up is adjusted number of times, then electric current adjustment number of times becomes 2,4 of second judging units judge whether the described electric current adjustment number of times (2 times) that adds up reaches predefined electric current and adjust number of times (3 times), be judged as not, described battery carried out the phase III constant current charge with described adjusted electric current (250mA).
In the phase III charging process, when first judging unit 2 judges that according to detecting unit 1 detected battery voltage value described detected magnitude of voltage reaches charging upper voltage limit 4.15V, then adjust charging flow to the second stage charging current value half or below, simultaneously, unit 3 electric current that adds up that adds up is adjusted number of times, then electric current adjustment number of times becomes 3,4 of second judging units judge whether the described electric current adjustment number of times (3 times) that adds up reaches predefined electric current and adjust number of times (3 times), be judged as is then to finish whole charging process.
