Description
Technical field
The utility model relates to a kind of electric supply installation, particularly a kind of DC suppling device belongs to power supply
Technical field.
Background technology
At present, the employed battery of electric motor car is the total voltage that the mode that adopts three closed type maintenance-free batteries to be connected in series improves battery, to satisfy required 36V voltage.But, when many batteries are connected in series power supply, can produce the inconsistency of each cell voltage.A large amount of experimental observations are confirmed, during battery power discharge, always there is a less battery of capacity can put electricity or overdischarge in advance, this battery is when charging once more, its terminal voltage will uprise, and along with the increase of charging times, the battery both end voltage will raise time by time, up to rising to more than the 14.5V, cause dehydration.Dehydration will cause battery capacity to reduce, and this battery useful life is shortened in so vicious circle, influences whole DC suppling device operate as normal.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of DC suppling device is provided, and makes its often voltage of interior each battery of balancing battery group, prolongs the useful life of battery, reduces the powered by direct current cost.The utility model is achieved by the following technical solution, mainly comprise: four synchro switches are K1, K2, K3, K4, three 12V closed type maintenance-free batteries are E1, E2, E3, every switch is by A, B, C, it is fixed contact, the normal battle, normally closed point is formed, its connected mode is: the negative pole of battery E1 is connected with the A of K switch 1, the positive pole of battery E1 is connected with the A of K2, the B of the negative pole of battery E2 and K switch 2, the C of K1, the A of K3 connects, the C of the positive pole of battery E2 and K switch 2, the A of K4 connects, the B of the negative pole of battery E3 and K switch 4, the C of K3 connects, the positive pole of battery E3 is connected with the C of K switch 4, the B of K switch 1, the B of K3 is vacant, the A of four synchronous single-pole double-throw switch (SPDT)s invests B, three battery E1, E2, E3 is the state of being connected in series, and its output voltage is 36V; The A of four synchronous single-pole double-throw switch (SPDT)s invests C, and three battery E1, E2, E3 become state in parallel; The just very controller positive terminal of battery E3, the negative pole of battery E1 are the controller anode connector, and the positive pole of battery E2, negative pole are respectively 12V charger positive terminal, anode connector.
Be connected in parallel and be applicable to when stopping power supply, by switching to four synchro switches, make three batteries change into the state of being connected in parallel by the state of being connected in series, at once by the higher battery of capacity the lower battery of capacity is replenished, promptly the capacity volume variance according to battery provides additional electric current automatically, voltage unanimity until all batteries, in time overcome because the voltage inconsistency of each battery that power supply station produces under the state that is connected in series, dwindle the voltage differences of each battery, voltage that can each battery of balance is for charging creates favorable conditions, when making charging, phenomenon can not appear overcharging in every battery, charging finishes every the cell voltage in back and all equates, individual cell overdischarge when avoiding powering, thus avoid the battery dehydration, can prolong battery useful life, reduce galvanic power supply cost.Use the 12V charger that battery pack is charged.
And by to the switching of four synchro switches, each battery of battery pack is changed into by mutual parallel connection be connected in series.When being connected in series, can reach 36V by output voltage, to the needs of voltage, realize normal power supply when satisfying power supply.Since when stopping power supply, the voltage of timely each battery of balance, and when power supply, the voltage of each battery is similar, can effectively avoid certain battery wherein the overdischarge phenomenon to occur.
The utility model can also adopt electromagnetically operated valve to be connected with ignition key, ignition switch is opened, inner four switches of electromagnetically operated valve electricity Attraction strap moving electromagnetic valve switch synchronously, make three batteries form mutual series connection shape, when closing key, inner four the synchronous switch backs of switch of electromagnetically operated valve, three batteries are parallel with one another, this moment between just can each battery of balance voltage or use the 12V charger that battery is charged.
The utility model is simple in structure, and is easy to use, and cost is not high, can also be applicable to the battery pack of forming by four above batteries, through experiment confirm, under equal conditions, suitable the utility model technology can make and prolong 1 to 2 times the useful life of battery, and its economic benefit is obvious, has promotional value.
