The below describes the operation principle of this control circuit.
In illumination period, solar battery array is except charging to lithium-ions battery for unnecessary electric energy the load; In the ground shadow phase, lithium-ions battery is directly by relay switch K1 discharge, and relay switch K1 is linked into bus by the remote control command transmission with lithium-ions battery and participates in whole star load supplying.The pressure limiting shunt circuit can guarantee that the charging final pressure of lithium ion battery limits within the limits prescribed all the time, and the operation principle of this pressure limiting shunt circuit is as follows:

This control circuit arranges third gear constant voltage charge magnitude of voltage by principal voltage circuit or the standby voltage circuit of transferring the files of transferring the files, and the lithium-ions battery that the below consists of take 7 joint single batteries (every batteries 4.1V) describes as example:
First grade: under normal circumstances, the constant voltage value of charging to lithium-ions battery is chosen in 28.7V, that is: single battery is full of voltage * battery strings interlink number=4.1V * 7 joint=28.7V.
Second gear: when satellite orbit is that morning and evening is during track, light application time is long, the ground shadow phase is short, consider that the lithium-ions battery initial stage is in the long-life that full electric attitude affects storage battery for a long time, then design is arranged on 27.3V with the constant voltage value at the rail initial stage, that is: single battery voltage * battery strings interlink number=3.9V * 7 joint=27.3V.
Third gear: when the joint of one in batteries storage battery is short-circuited, if also with former constant voltage value 28.7V to batteries charging then can cause over-charging of battery, therefore the constant voltage value 24.6V of short circuit one batteries is set, that is: single battery is full of series connection joint number=4.1V behind voltage * battery short circuit one joint * 6 joint=24.6V.
Above third gear constant voltage charge magnitude of voltage arrange respectively by remote control command control the contact switch J1 of the first relay and the second relay and J2 switch on and off to control, J1 and J2 switch on and off totally four kinds of states, utilized three kinds of states at this: 1. J1 is logical, J2 is logical, the corresponding constant voltage value of this state 24.6V; 2. J1 is logical, and J2 is disconnected, the corresponding constant voltage value of this state 27.3V; 3. J1 is disconnected, and J2 is disconnected, the corresponding constant voltage value of this state 28.7V; Thereby the access by controlling resistance changes the magnitude of voltage of the pin two of pulse width modulator SG1525 and changes charging constant voltage value.
What this control circuit was taked lithium-ions battery is that limited pressure is regulated, realize charging control function to constant voltage after the constant current of storage battery elder generation by active and standby pressure limiting shunt circuit, prevented that lithium-ions battery from being overcharged, realized better managing lithium-ions battery at rail by switching the constant voltage value simultaneously.
It is emphasized that; embodiment of the present invention is illustrative; rather than determinate; therefore the present invention is not limited to the embodiment described in the embodiment; every other execution modes that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope of protection of the invention equally.
