Description
Technical field
The utility model relates to a kind of charging station control circuit system, for solar energy civil power complementary type electric motorcar charging station provides a kind of automation, the duplicate supply control circuit system of switching mutually.
Background technology
Utilizing solar energy to generate electricity is the main means that human development utilizes solar energy; Yet because the intermittence of solar radiation; Single solar power system often appears at continuous when overcast and rainy, and battery tension is not enough, and the situation of continuous power can't be provided to the external world.Solar energy and civil power are formed the duplicate supply complementary power supply system; Not only effectively solve solar energy and utilized problem of unstable; Can reduce simultaneously the capacity of solar cell and storage battery, compare, reduce cost to a great extent with single solar electric power supply system.
The utility model content
The utility model has mainly solved single solar electric power supply system solar energy has been utilized the huge problem of instability and solar cell and battery capacity.
For addressing the above problem, the technical scheme that the utility model adopts is:
The complementary electric motorcar charging station control circuit system of a kind of solar energy civil power; Comprise controller; And the mains supply that is connected with controller, solar cell, charger, storage battery; Solar cell is converted into electric energy with solar radiation, be sent in the storage battery to store, and extra electric weight is used for charger is electric motor car charging; The effect of storage battery is the electric energy that stores solar array by day and produced, and discharge energy stored evening, supplies the charging at night; Controller is totally monitored solar cell, battery tension, mains supply and charger state; For storage battery provides best charging current and voltage; Protect storage battery simultaneously; Avoid overcharge of a battery or overdischarge, accomplish the switching between solar cell and the mains supply when needing, guarantee the charger continuous firing; Mains supply is occurring continuously gloomy day as the stand-by power supply in the system, and storage battery can not convert civil power into by controller and supply power to charger when the charger normal power supply because charging voltage is not enough.
Said controller adopts programmable logic controller (PLC); Its working mode change flow process is a system when starting working, and controller at first detects the terminal voltage of storage battery, according to the size of terminal voltage; Get into the different working pattern: the solar cell terminal voltage is judged as Night in 12 volts; Terminal voltage is judged as day mode greater than 12 volts.
Said day mode is: controller at first cuts off two current supply circuits; Detect battery tension; And judge according to accumulator voltage and the state of charge of storage battery to carry out the operation corresponding state under: when storage battery reached overshoot point, no matter solar array voltage just; The charge in batteries loop all is disconnected, and stops charging; After battery tension was reduced to and put a little,, adopt the DC charging mode for replenishing battery tension as early as possible; Do not have overshoot at battery tension, do not reduce to when putting yet, adopt pulse charging; In the free position of this pattern, controller carries out periodicity to accumulator voltage and detects, and judges whether to stop charging or carries out the charging modes conversion.
Said Night is: after getting into this pattern, controller cuts off charge circuit, and the detection accumulator voltage is also judged, to determine charger by storage battery power supply or by mains powered.If by mains powered, then controller only need detect the terminal voltage of solar cell, to judge whether switching working mode; If by storage battery power supply, then controller at first reads storage battery half-power discharge flag bit, and to determine whether the half-power power supply, if selected the half-power power supply, then storage battery carries out the half-power power supply, otherwise storage battery normally discharges; No matter normal power supply still is the half-power power supply, and controller is all wanted periodic test accumulator voltage and solar cell terminal voltage, need switch to the mains powered pattern and whether need be transformed into the pattern of working by day judging whether.
The utility model is to the solar electric power supply system of single form; Having proposed programmable logic controller (PLC) is core; Civil power, battery power convert the improvement that charger provides uninterrupted power supply mutually into; Efficiently solve the instability problem that single solar energy utilizes, reduced the capacity of solar cell and storage battery.
