Abstract
The invention relates to an intelligent charging transition circuit for a storage battery. The intelligent charging transition circuit for the storage battery comprises a rectifier bridge, a relay and a diode, and is characterized in that an external power supply is input through the rectifier bridge; the output of the rectifier bridge charges the storage battery through a storage battery polarity detection circuit consisting of the relay and the diode; the storage battery polarity detection circuit consists of two subcircuits which are connected in parallel; one subcircuit is formed in the way that the diode is connected in series with the relay in a forward direction, and the other subcircuit is formed in the way that the diode is connected in series with the relay in a reverse direction; and the storage battery polarity detection circuit is output to the storage battery in parallel. The intelligent charging transition circuit for the storage battery has a simple detection circuit, adopts few components, is applicable to various occasions which provide wind energy, solar energy and mains supply to the storage battery for charging, and has a good using value.
Description
Technical field
The present invention relates to a kind of intelligent accumulator charging transition circuit, be applicable to the various occasions that wind energy, solar energy and civil power provide the energy to charge a battery.
Background technology
In wind energy and solar power system, all to adopt storage battery to come storage of electrical energy.In a single day the polarity of the power supply of the positive-negative polarity of storage battery and wind energy and solar energy connect instead, will damage whole system.Have at present and adopt anti-reverse storage battery combination circuit, sort circuit will be connected into one with diode and storage battery, as a whole to external connection, in case connect anti-storage battery then can't work, also wants rewiring if will normally move, and complex operation uses inconvenient.
Summary of the invention
In view of the deficiency of above-mentioned technology, the purpose of this invention is to provide a kind of intelligent accumulator charging transition circuit, this circuit need not to distinguish the polarity of input power supply, does not also differentiate the polarity of storage battery.As long as between input power supply and storage battery, adopt this circuit, just can guarantee that whole system works reliably.
The present invention adopts following scheme to realize: a kind of intelligent accumulator charging transition circuit comprises the rectifier bridge that D1 ~ D4 forms, K1 ~ K2 relay, D5 ~ D6 diode.It is characterized in that: described intelligent accumulator charging transition circuit, input termination external power source, output termination storage battery, the input that connects and output are not all wanted necessary of identifying polarity.The rectifier bridge that D1 ~ D4 forms guarantees no matter input polarity how, can both guarantee that the A terminal potential is higher than the B terminal potential.K1 ~ K2 forms the accumulator polarity testing circuit: when storage battery is last negative just down, and then K1 action, the action of K1 normally opened contact guarantees that foreign current flows to battery positive voltage-negative pole from the A point, the K1 normally opened contact flows to the B point.When storage battery is negative for just going up down, the K2 action, the action of K2 normally opened contact guarantees that foreign current flows to battery positive voltage-negative pole from the A point by K2, the K2 normally opened contact flows to the B point.
Electric circuit inspection circuit of the present invention is simple, adopts components and parts less, and applicable to wind energy, the various occasions that solar energy and civil power provide the energy to charge a battery have use value preferably.
Description of drawings
Fig. 1 is circuit theory schematic diagram of the present invention.
Fig. 2 is circuit embodiments circuit diagram of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of intelligent accumulator charging transition circuit, the external power source input charges a battery after translation circuit, output and commutation circuit output.
Fig. 2 is the specific embodiment circuit diagram, a kind of intelligent accumulator charging transition circuit, comprise rectifier bridge, relay, diode, it is characterized in that: external power source is imported through rectifier bridge, the output of rectifier bridge charges a battery via the accumulator polarity testing circuit that relay and diode constitute, the branch road that the branch road that described accumulator polarity testing circuit is made of the diode forward series relay and diodes in reverse series relay constitute is in parallel and forms, and storage battery is exported in the parallel connection of described accumulator polarity testing circuit.Respectively the connect normally-closed contact of non-branch road relay of described accumulator polarity testing circuit two branch roads.What frame of broken lines partly represented among Fig. 2 is exactly a kind of intelligent accumulator charging transition circuit.
Be that sun-generated electric power is example with input, solar cell is through the rectifier bridge output that D1 ~ D4 forms, and so just makes no matter solar cell input polarity is negative or just going up the current potential that the negative current potential that can both guarantee the A end is held greater than B down just down on being.
Direct current relay K1, K2 constitute the accumulator polarity testing circuit.In the time of negative just down on the polarity of storage battery is, that direct current relay K1 gets is electric, K2 must not.Direct current relay K1 gets electric its normally opened contact closure that makes.The electric current of A end is flowed through and is flowed to the B point again behind K1 normally opened contact, battery positive voltage-negative pole, the K1 normally opened contact.When the polarity of storage battery is just to go up down negative the time, that direct current relay K2 gets is electric, K1 must not.Direct current relay K2 gets electric its normally opened contact closure that makes.The electric current of A end is flowed through and is flowed to the B point again behind K2 normally opened contact, battery positive voltage-negative pole, the K2 normally opened contact.
The normally-closed contact of direct current relay K2 and direct current relay K1 are in series and the normally-closed contact of direct current relay K1 and direct current relay K2 are in series, and purpose is in order to play the effect of interlocking.Having guaranteed wherein to have an actuating of relay, and another relay just can not move certainly.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
