Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1, comprise mains-supplied circuit and civil power charge-discharge circuit, said mains-supplied circuit is made up of the mains supply by-pass switch and the user interface that connect successively; Said civil power charge-discharge circuit comprise successively the mains supply that connects, first contactor, second contactor, AC power supply, charging control and battery detection unit, energy-storage battery, online inverter and user interface form; Said charging control and battery detection element connection system control unit, system control unit connects first contactor, second contactor, user interface and online inverter respectively.
When system control unit realizes that unusual or storage battery externally discharges when line voltage, control first contactor and break off, control the second contactor adhesive in the time of need be to battery charge, and control battery charge and monitor each cell voltage of battery pack.The charging of control lithium battery intelligent is realized in charging control and battery detection unit, and the battery status monitoring.User interface is the display device state, and through serial ports and system control unit communication, the user can import battery charge time and discharge time in user interface according to self needs.
The civil power monitoring means is whether the monitoring line voltage is normal, and the civil power monitoring means is isolated and gathered line voltage through voltage transformer; Calculate the line voltage effective value through the real effective circuit; Through comparison circuit line voltage effective value and setting voltage bound are compared, when the line voltage effective value exceeded the setting voltage bound, observation circuit sent warning.
It is the accumulation power supply of core that the utility model adopts this energy storage technology of ferric phosphate lithium cell, and this novel energy environmental protection of lithium battery is no matter produce, use and scrap; Do not contain, do not produce yet poisonous and harmful heavy metallic element and materials such as any lead, mercury, cadmium; Have high storage power density,, have tangible cost and service life advantage than existing energy storage technologies such as pumped storage, compressed-air energy storages; Economic benefit is outstanding; Demand is huge, has a extensive future, than traditional lead-acid battery safety and environmental protection.
The utility model adopts system control unit to carry out intelligent Single Component Management, and system control unit can adopt the chip of model: STC90C58AD.The no-load loss that the utility model can avoid soft-offs such as TV to bring, the power supply that can cut off the soft-off system automatically.Native system adopts the special charging machine to give lithium cell charging, and intelligent charge technology, charging control unit adopt import army grade integrated circuit, can use the chip of model: OZ8920, and reliable and stable, failure rate is low, and reliability is high.
With respect to large-scale power station, the utility model accumulation power supply is mainly towards average family, small-business industrial area, or limits the zone of small-sized firepower peaking generation station or the development of other high pollution power station because of the environmental protection reason.Not only when peak of power consumption, the ladder power supply is provided, save electric cost, but also can make that electronic equipment exempts from that civil power outage, voltage are low, the influence of voltage die and surge.
Embodiment recited above describes the utility model preferred implementation; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design philosophy; Common engineers and technicians make the technical scheme of the utility model in this area various distortion and improvement all should belong to the protection range of the utility model.
