With conveniently.
The full power production photovoltaic battery is that the full medium-sized photovoltaic cell of electricity can be distributed to shared charging cabinet etc., to meet user's concentration
The urgent charge requirement of formula can also be used as the charge power supply of existing shared charger baby.By taking the common model of electric vehicle as an example, it can set
Setting capacity is 48V/10Ah battery pack.
The full power production photovoltaic battery can be distributed to fixed direct current electricity system for full TV university type photovoltaic cell, such as: work
Place, public place of entertainment and domestic consumer etc..To meet household DC electric appliance, architectural lighting (LED light) and security system to electricity
The demand of energy.
Power station, electrical changing station, shared charging cabinet and fixed direct current electricity system is borrowed all to have in the DC distribution station
Electricity inductor can send signal to dispatching platform automatically when battery power deficiency, it is made to carry out intelligent distribution.
Shared charging cabinet in the DC distribution station is the need to be charged by discharge controller realization photovoltaic cell to it
It asks.
Fixation direct current electricity system in the DC distribution station can realize that photovoltaic cell is straight to its by DC bus
Connect the purpose of charging；When photovoltaic cell not enough power supply, electricity inductor can issue signal, if photovoltaic cell cannot in time more
It changes, traditional power supply mode of " AC-DC " can be started when power transmission amount is reduced to limit value by controller for urgent need.The electricity
It measures insufficient photovoltaic cell and can recycle and recharge, make its Infinite Cyclic in the photovoltaic DC distribution system.Realize saving
Resource, protection environment, promote sustainable development.
The allocator of photovoltaic DC distribution system of the present invention are as follows: the photo-voltaic power generation station is by solar energy power generating board group
Power storage is converted light energy into full power production photovoltaic battery at solar energy power generating plate when, start-up operation, when full electric light lies prostrate
When battery is fully charged, the inductive signal lamp of mounting electricity storage pack becomes green from red, is then transmitted a signal to and is matched by induction system
Platform is sent, dispatching platform carries out the intelligent distribution of photovoltaic cell to DC distribution station according to the demand of user；When borrow power station, change electricity
It stands, when not enough power supply occurs in photovoltaic cell in shared charging cabinet, fixed direct current electricity system, inductive signal lamp becomes red from green
Color, then induction system can send a signal to dispatching platform, and dispatching person can be according to the position of the photovoltaic cell in dispatching platform
And the distribution of model combination photo-voltaic power generation station carries out recycling and recharges.
Compared with prior art, it advantages of the present invention and has the beneficial effect that
The present invention, directly by the power storage of solar power generation in polytypic photovoltaic cell, is not examined using photo-voltaic power generation station
