A kind of equipment of electric automobile charging station emergency service, the energy-storage system that comprises electric automobile charging station, energy accumulation current converter, electrical network, change electric machine people and low-voltage alternating-current bus, low-voltage alternating-current bus connects electrical network, the energy-storage system of electric automobile charging station is connected on low-voltage alternating-current bus through energy accumulation current converter, and the power end that changes electric machine people is also connected on low-voltage alternating-current bus.
The energy-storage system of described electric automobile charging station is energy-storage battery.
At charger output, increase energy accumulation current converter, realization is changed electric machine people and is supplied power with double circuit, and electrical network is switched to the energy-storage system supply power mode by electric automobile charging station after having a power failure suddenly.
The beneficial effects of the utility model: electric automobile charging station has energy-storage system, this energy-storage system can not exist does not have electric situation, can guarantee partial redundance electric weight always.Utilize existing energy-storage battery to realize the emergency service that changes electric machine people emergency-lighting set, complete and change electric process.Be exactly to increase energy accumulation current converter at charger output, realization is changed electric machine people and is supplied power with double circuit, and after system power failure, is switched to by energy-storage system supply power mode, guarantees to change electronic completing, and saves this part of UPS simultaneously, has greatly reduced cost.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram;
In figure: the energy-storage system 1 of electric automobile charging station, energy accumulation current converter 2, electrical network 3, change electric machine people 4, low-voltage alternating-current bus 5.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
A kind of equipment of electric automobile charging station emergency service, the energy-storage system 1 that comprises electric automobile charging station, energy accumulation current converter 2, electrical network 3, change electric machine people 4 and low-voltage alternating-current bus 5, low-voltage alternating-current bus connects electrical network, the energy-storage system of electric automobile charging station is connected on low-voltage alternating-current bus through energy accumulation current converter, and the power end that changes electric machine people is also connected on low-voltage alternating-current bus.
The energy-storage system of described electric automobile charging station is energy-storage battery.
At charger output, increase energy accumulation current converter, realization is changed electric machine people and is supplied power with double circuit, and electrical network is switched to the energy-storage system supply power mode by electric automobile charging station after having a power failure suddenly, the energy-storage system of electric automobile charging station participates in the peak load shifting of electrical network, and total energy guarantees partial redundance electric weight; Under normal circumstances, by electrical network, to changing electric machine people, powered; When being in an emergency, when electrical network has a power failure suddenly, start energy accumulation current converter, utilize the electric energy of the energy-storage system of electric automobile charging station to continue, to changing electric machine people power supply, until complete, to change electric process; Utilize the energy-storage system of electric automobile charging station to realize the emergency service that changes electric machine people emergency-lighting set, complete and change electric process.The energy-storage system of described electric automobile charging station is energy-storage battery.
