Abstract
The utility model discloses an automatic charging and discharging controller. The utility model is suitable for charging and discharging a nickel-cadmium battery or a maintenance-free battery in a high-power DC power supply. The utility model comprises a charger and a charging and discharging circuit. The charger charges the battery through a rectification circuit. When the voltage of the battery reaches 285V, an over-voltage relay works, and the charger turns into floating charging state. When the battery discharges to a discharging resistor and lowers the voltage of the battery below 180V, an under-voltage relay works, and the charger turns to intensified charging state. The battery is recurrently charged and discharged by the method. The battery can be always in full capacity state. In addition, the service life of battery can be extended by the utility model.
Description
The utility model relates to the ickel-cadmium cell in a kind of automatic control equipment that discharges and recharges, particularly high-power DC power supply or the automatic control equipment of maintenance-free battery charge and discharge.
At present; the charge and discharge device that is used for high-power DC power supply ickel-cadmium cell or maintenance-free battery only is the simple combination of charger and battery pack; battery do not had overcharge, cross and put protection, had a strong impact on the useful life (being generally its useful life 2～3 years) of battery.Filling by force in addition with floating charge needs two chargers to finish, and can only manual switch, complex structure, and volume is big, and it is also cumbersome to operate.
The purpose of this utility model is to provide a kind of automatic control equipment that discharges and recharges, and this device overcharges, crosses and put protection, the long service life of battery battery; Simple in structure, volume is little, and is easy to use.
The automatic control equipment that discharges and recharges of the present utility model comprises a constant voltage constant current charging machine CV1, be characterized in being serially connected with diode 2V1,2V2 between the positive pole of the positive pole of battery GE1 and charger, be reverse connection between this two diode and negative pole docks with negative pole, their positive pole joins with the positive pole of charger CV1 and battery GE1 respectively; Be parallel with overvoltage relay FV2 and under-voltage replay FV3 between the positive and negative electrode of battery, discharge resistance Rfz also is connected in parallel by the positive and negative electrode of relay K M2 and battery.Be in series with electronic switch 2V3 and diode 2V4 between the negative pole of diode 2V1,2V2 and the positive pole of load; Be serially connected with diode 2V5 between the positive pole of diode 2V2, battery GE1 and the positive pole of load, the adjustable resistance RP1 of floating current and the backup protection hand switch SA1 of charger CV1 are used to adjust; the standby shelves of this hand switch link to each other with electronic switch 2V3, and the two ends of described electronic switch 2V3 and diode 2V1 are parallel with relay K M1 respectively.Between the negative pole of the positive pole of diode 2V1 and battery GE1 and be connected to and be used for the relay FV1 that automatically reports to the police.
Because the utlity model has and discharge and recharge automatic safety device, cell voltage is too high or too low all can be controlled automatically, battery can not occur overcharging, put excessively and emit the liquid phenomenon, has prolonged its useful life greatly; Discharge and recharge only charger of need of automatic control equipment owing to of the present utility model again, and fill by force, all fill with floating charge and can both change automatically from motion tracking, simple in structure, volume is little, and is easy to use.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is to discharge and recharge the automatic control equipment schematic diagram.
With reference to accompanying drawing, the automatic control equipment that discharges and recharges of the present utility model comprises a constant voltage constant current charging machine CV1, be serially connected with diode 2V1,2V2 between the positive pole of battery GE1 and the positive pole of charger, be reverse connection between this two diode, be that its negative pole docks with negative pole, their positive pole joins with the positive pole of charging utmost point CV1 and battery GE1 respectively.The positive and negative electrode of battery GE1 is parallel with overvoltage relay FV2 and under-voltage replay FV3, and discharge resistance Rfz also is connected in parallel by the positive and negative electrode of relay K M2 and battery.Be serially connected with electronic switch 2V3 and diode 2V4 between the negative pole of diode 2V1,2V2 and the positive pole of load.Be serially connected with diode 2V5 between the positive pole of diode 2V2, battery GE1 and the positive pole of load, be used to adjust the adjustable resistance RP1 of floating current and the backup protection hand switch SA1 of charger CV1, the standby shelves of this hand switch link to each other with electronic switch 2V3.The two ends of electronic switch 2V3 and diode 2V2 are parallel with relay K M1 respectively.Between the negative pole of the positive pole of diode 2V1 and battery GE1 and be connected to and be used for the relay FV1 that automatically reports to the police.Between the positive pole of battery GE1 and the diode 2V5, between adjustable resistance RP1 and the backup manual protection switch SA1 and be serially connected with ammeter 1PA, 3PA and the 2PA that standby current changes between diode 2V4 and the load end respectively.Discharge and recharge automatic control equipment when operation when of the present utility model, charger CV1 charges to battery GE1 by diode 2V1,2V2.When cell voltage reaches 285V, overvoltage relay FV2 action, charger CV1 changes floating charge state over to.When relay K M2 closed, battery GE1 discharged to discharge resistance Rfz.When the voltage of battery GE1 is lower than 180V, under-voltage replay FV3 action, this moment, relay K M2 disconnected, charger CV1 changes the state that fills by force over to, when the voltage of battery GE1 is charged to 285V, repeat said process, thereby the automatic control that realization discharges and recharges makes battery GE1 be in the full capacity armed state all the time.In case the utility model charger CV1 in service breaks down, relay FV1 promptly can report to the police automatically, and the backup protection hand switch is purchased with shelves, and charger CV1 enters the emergent charging state.All filling under the state, the KM1 adhesive, not conducting of electronic switch 2V3, battery GE1 and load disconnect.When the cathode voltage of diode 2V4 is lower than 220V, electronic switch 2V3 conducting.
In the utility model the foregoing description, between the two ends of the positive and negative electrode of battery GE1 and overvoltage relay FV2, under-voltage replay FV3 and discharge resistance Rfz, be serially connected with fuse 2FV1 and 2FV2 respectively, be connected to voltmeter 1PV between this two fuse.The both positive and negative polarity of battery GE1 all is connected to air switch 2F4.
