Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the whole system in the utility model, as shown in Figure 1: the system in the utility model is by D.C. contactor K1 (contact is normally closed), and MCU controller, current sensor, can control DC/DC module, and RS485 communication module forms.
When electrical network normally works, load supplying is exported by charger provides, and is supplied to charge in batteries and load supplying.When needs discharge with this device, controlled the process of whole electric discharge by controller.First contactor normally-closed contact disconnects, DC/DC boost module input voltage and output voltage superposition, and peak load both end voltage gradually, when battery tension and DC/DC module voltage sum are higher than charger output voltage, charger stops output current.The electric current of now load is just that storage battery provides completely, and controller gathers discharging current, and control storage battery and be in constant-current discharge state, storage battery starts constant-current discharge.Calculate discharge time and ampere-hour number, system time monitoring busbar voltage in discharge process, in battery discharging process, battery tension can reduce, the voltage that DC/DC module output voltage boost compensation storage battery reduces, moment stablizes busbar voltage (this voltage is higher than charger output voltage), when mains failure, busbar voltage also not power down, reaches the object of online electric discharge.
Fig. 2 is the structured flowchart of the DC/DC converter in the utility model.As shown in Figure 2: described charge and discharge device comprises control circuit and DC/DC booster circuit; DC/DC booster circuit comprises: EMC filter circuit, BOST DC voltage booster circuit, DC/AC inverter circuit, AC/DC isolated variable circuit, output filter circuit; Control circuit is connected to control DC/AC inverter circuit on DC/AC inverter circuit; The civil power of electrical network input is transformed into galvanic current through BOST DC voltage booster circuit input dc power after EMC filter circuit filtering, enter DC/AC inverter circuit through the direct current of BOST DC voltage booster circuit and DC inverter become high-frequency alternating current, from DC/AC inverter circuit out after high-frequency alternating current high-frequency alternating current to be rectified into after direct current through output filter circuit the abundant filtering of direct current exported through AC/DC isolated variable circuit.
Fig. 3 is the equivalent circuit diagram of discharge and recharge in the utility model.As shown in Figure 3: in direct current system, the unilateal conduction characteristic of diode is utilized, the function that the system that realizes is discharged online.In discharge process, two kinds of situations are had to stop electric discharge: when 1, receiving stopping electric discharge order or fault.2, setup parameter is reached, such as discharge time, capacity etc.
System stops electric discharge, and stop DC/DC module to export, charging system starts to charge a battery, and reduces the pressure reduction of storage battery and charger, and pressure reduction is less than establishes timing contactor normally-closed contact to close, restoring scene state.
