Exchanging under all normal running status of input and console switch, the pairing set of devices of full-automatic phased trigger CDJ1 becomes the master and uses charger, and the pairing set of devices of full-automatic phased trigger CDJ2 becomes the stand-by heat charger; Main provide closing bus bar, the control bus of flow directing device, all load and energy of batteries charging, and guarantee that voltage stabilizing various output states under and constant current accuracy, ripple coefficient etc. are controlled in the scope of national standard permission with charger.While is at the output of controllable silicon rectifying bridge M1, be provided with voltage monitoring auxiliary relay KZB, KZB adhesive during normal the operation, make another charger be in hot stand-by duty, output voltage is made as about 1/2 of normal float charge voltage output, purpose is to make filtering capacitor CB1 maintain certain electric charge, and electrochemical capacitor is dry to lose efficacy because long-term dead electricity makes to avoid.The charger input is provided with circuit breaker Q C1-2 and does manually to be deciliter a control and an overcurrent protection, is provided with the electric quantity monitoring of electric parameters transducer as the isolation of output, VC1 and VB1 diode is arranged as the check protection of avoiding interfering with each other; The operate condition of charger and all peripheral components and the electric weight of output all send into PLC as program control and touch-screen dynamically with the foundation of data demonstration.

Fig. 4 shows charger to battery charging process (is example with 220V65AH direct current cabinet):

Floating charge state: when the capacity of storage battery kept＞90%, charger was in floating charge state to battery pack, promptly with the source of stable pressure output of 243V, replenished the self discharge energy loss of batteries.

All fill state: at floating charge state, when PLC presetting apparatus monitoring battery charge 〉=5A and continuous 30 seconds or when floating charge state reaches 180 days continuously, PLC control auxiliary relay KJC action, this moment, the voltage set point of charger output was 253V, charger enters the state that all fills, because voltage raises, it is big that charging current becomes, when reaching the set point of constant current, full-automatic phased trigger constant current control ring works, and makes output current remain on 6.5A, and the voltage of output changes with battery voltage, when charger output voltage during near 253V, charging current descends, and full-automatic phased trigger constant current control ring begins to withdraw from control, makes the charger output voltage remain on 253V, charging current diminished gradually along with the time, and also trend is sufficient gradually for the electric power storage energy of battery pack.Fill all that the state time reaches 12 hours or charge in batteries electric current when being varied down to 1.3A when whole, PLC control auxiliary relay KJC recovers, and charger is got back to the floating charge state of 243V source of stable pressure output, and the state that all fills finishes.

Setting by touch-screen, charger can be set in battery pack temperature compensating charge state, PLC control this moment auxiliary relay KTW action, the master is subjected to PLC analog quantity output control with the charger output voltage values, to guarantee that battery pack float charge voltage under the high temperature more than 40 ℃ reduces with the rising of temperature, avoid the battery pack of floating charge under the high temperature unaffected useful life, temperature compensation coefficient is-3mv/ ℃.

The automatic switching procedure of primary, spare charger IA, IIA:

During operate as normal, owing to main output with charger I is provided with voltage monitoring auxiliary relay KZB, when its adhesive, another charger II is controlled at half by the KZB contact and presses output, because the effect of check diode VB1 is not to external voltage output, so be in stand-by state.

When the main voltage that exchanges input dead electricity or output with charger IA exceeds the allowed band that PLC sets and when PLC control auxiliary relay KBN1 is moved, the master exports with regard to no-voltage with charger IA, voltage monitoring auxiliary relay KZB dead electricity, the control of standby charger IIA out-off voltage monitoring auxiliary relay KZB contact makes output voltage rise to 243V to substitute the main charger IA work of using.Same standby charger IIA voltage is at this moment monitored by PLC also, and PLC control auxiliary relay KBN2 also can control standby charger IIA and withdraw from failure operation;

3: battery apparatus: battery pack as energy storage device, exchanging input just often, not to bussed supply, is the storing energy that maintenance is controlled oneself in this flow directing device, leans on the energy of the floating charge current compensation self discharge of charger; When exchanging dead electricity, batteries is directly powered to control bus KM to closing bus bar HM and by step-down silicon chain DW in official hour without interruption.
