Abstract
The utility model discloses a multi-group lithium battery time-interval based charging system which comprises a current-limiting control and charging current control module, a time-interval based switching module, a battery detecting and voltage detecting and control module, a voltage control/current control/time record control (CV/CC/TR) module, a status indication control module and a battery interface. The current-limiting control and charging current control module is connected with the time-interval based switching module, and the battery detecting and voltage detecting and control module are respectively connected with the time-interval based switching module, the CC/CV/TR module and the status indication control module. The current-limiting control and charging current control module and the time-interval based switching module are respectively connected with the CC/CV/TR module. The integration of the multi-group lithium battery time-interval based charging system can charge the multi-group lithium batteries and the multi-group lithium batteries do not mutually influence each other. The battery detecting and voltage detecting module is capable of judging the connection of each group of battery and the charging capacity, and therefore, the corresponding time-interval based switching module can be adjusted. The current-limiting control module and an output module can detect an external power supply, if the external power supply fails to provide the stated charging current, the system can automatically switch to small current charging.
Description
Technical field
The utility model relates to many group lithium cell charging methods that are used to.
Background technology
present lithium cell charging control IC is primarily aimed at a lithium battery and charges.If a plurality of lithium batteries are adopted series system basically, can't a plurality of lithium batteries of similar parallel connection be charged; More can't be to charging without the lithium battery group of partial volume coupling.
In order to solve above-mentioned situation, a plurality of lithium batteries that the utility model solves similar parallel connection charge, simultaneously a compatible with single battery charge.
Summary of the invention
The utility model discloses a kind of lithium battery time-sharing charging system that organizes more, comprise Current limited Control and charging current control module, timesharing handover module, battery detecting and voltage detecting and control module, CV/CC/TR control module, state indication control module and battery interface; Current limited Control and charging current control module are connected with the timesharing handover module; Battery detecting and voltage detecting are connected with timesharing handover module, CC/CV/TR control module, state indication control module respectively with control module; The CC/CV/TR control module is connected with the timesharing handover module with Current limited Control and charging current control module respectively.
As preferably, the timesharing handover module can decide the passage of selecting battery according to situation that inserts battery and electric weight.
As preferably, comprise detection in Current limited Control and the charging current control module to external power source, if external power source can't provide the charging current that sets, then system automatically switches to low current charge.
Description of drawings
Fig. 1 is the block architecture diagram of the utility model specific embodiment one.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As shown in Figure 1; A kind of lithium battery time-sharing charging system that organizes comprises Current limited Control and charging current control module 1, timesharing handover module 2, battery detecting and voltage detecting and control module 3, CV/CC/TR control module 4, state indication control module 5 and battery interface more; Current limited Control and charging current control module 1 are connected with timesharing handover module 2; Battery detecting and voltage detecting are connected with timesharing handover module 2, CC/CV/TR control module 4, state indication control module 5 respectively with control module 3; CC/CV/TR control module 4 is connected with timesharing handover module 2 with Current limited Control and charging current control module 1 respectively.
When the external power source access, battery detecting and voltage detecting and control module 3 can be selected the passage of required charging according to the state of load battery.Battery detecting and voltage detecting and control module 3 detect has only battery one and battery two accesses, switches between 2 pairs of batteries one of timesharing handover module and the battery two pairing passages.Switching mode can be that timesharing is switched, and also can be full of battery pack earlier and switch to battery two again and again. detecting like battery detecting and voltage detecting and control module 3 only has battery one, and timesharing handover module 2 is only opened battery one pairing people having a common goal.
Battery detecting and voltage detecting and control module 3 judge that according to the voltage that detects charging charging is operated in the CC pattern or is operated in the CV pattern.
Comprise the detection to external power source in Current limited Control and the charging current control module 1, if external power source can't provide the charging current that sets, then system automatically switches to low current charge.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection range of the utility model technical scheme.
