The storage battery charging parallel connection device provided by the utility model has the advantage that the storage battery can realize serial connection during working and parallel connection during charging through the connection between the relay contacts. In comparison with the prior art, the storage battery charging parallel connection device is simple in structure, convenient in use, safe, reliable and so on.
Description
Technical field
The utility model relates to a kind of charge in batteries and uses device, especially can realize the device of connection in series-parallel conversion between the storage battery.
Background technology
Equipment such as prior electric car are the polylith storage battery to be cascaded charge, and cause whole group storage battery to be full of because of indivedual accumulators store electric weight descend after use a period of time, perhaps have the phenomenon that overcharges damage storage batterys such as bulge.
The utility model content
The technical problem that the utility model will solve is for overcoming above-mentioned deficiency, and a kind of charge in batteries shunting means simple in structure, easy for operation is provided.
The utility model is taked following technical measures: a kind of charge in batteries shunting means; Comprise cradle, at least two storage batterys; Also comprise at least two relays; First battery positive voltage is connected the back and is connected with anodal normally-closed contact with one transfer contact of first relay, first battery terminal negative is connected the back and is connected with the negative pole normally-closed contact with another transfer contact of first relay; Second battery positive voltage is connected the back and is connected with anodal normally-closed contact with one transfer contact of second relay, second battery terminal negative is connected the back and is connected with the negative pole normally-closed contact with another transfer contact of second relay; The said first relay negative pole normally-closed contact is connected with the anodal normally-closed contact of said second relay; The anodal normally opened contact of first relay is connected with second relay positive pole normally opened contact, the first relay negative pole normally opened contact be connected with the second relay negative pole normally opened contact; First relay coil and second relay coil are connected in parallel between the both positive and negative polarity of cradle.
The beneficial effect of the utility model is the connection that utilizes between relay contact, the purpose of parallel connection when series connection when realizing battery-operated and charging.Compared with prior art, have advantages such as simple in structure, esy to use, safe and reliable.
Description of drawings
Fig. 1 is the electrical block diagram of a kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
As shown in the figure; A kind of charge in batteries shunting means; Comprise cradle 1, at least two storage batterys 2,3; Comprise that also at least two relays 4,5, the first storage batterys 2 anodal backs that are connected with 4 one transfer contacts of first relay are connected with anodal normally-closed contact 6, first storage battery, 2 negative poles are connected the back and are connected with negative pole normally-closed contact 8 with 4 another transfer contacts of first relay; Second storage battery, the 3 anodal backs that are connected with 5 one transfer contacts of second relay are connected with anodal normally-closed contact 10, and second storage battery, 3 negative poles are connected the back and are connected with negative pole normally-closed contact 12 with 5 another transfer contacts of second relay; The said first relay negative pole normally-closed contact 8 is connected with the anodal normally-closed contact 10 of said second relay; The anodal normally opened contact 7 of first relay is connected with second relay positive pole normally opened contact 11, the first relay negative pole normally opened contact 9 be connected with the second relay negative pole normally opened contact 13; First relay coil 4 and second relay coil 5 are connected in parallel between the both positive and negative polarity of cradle 1.
The operation principle of the utility model is; With two group storage batteries is example; When storage battery does not charge operate as normal; Being connected of normally-closed contact 10 realized being connected in series between the storage battery through the first relay negative pole normally-closed contact 8 and second relay are anodal, anodal normally opened contact 7 of first relay and the second relay negative pole normally-closed contact, the 12 common outputs 14 of forming batteries.When charge in batteries; The both positive and negative polarity normally opened contact of first relay and second relay is closed respectively; Because the anodal normally opened contact 7 of first relay is connected with the anodal normally opened contact 11 of second relay; The negative pole normally opened contact 9 of first relay is connected with the negative pole normally opened contact 13 of second relay, thereby has realized being connected in parallel between the storage battery, has prevented that storage battery can't be full of or overcharge phenomenon.Thereby prolong storage battery useful life greatly, reduce cost of equipment maintenance and can reduce environmental pollution.
The utility model as required storage battery with fuse is installed between relay is connected, LED light and current-limiting resistance also are installed in circuit.Parallel connection conversion when the utility model can realize equally that two above storage batterys charge simultaneously; Circuit is equipped with the relay number of same quantity according to the number of storage battery; The circuit catenation principle is identical with two storage battery catenation principles; The anodal normally opened contact of first relay and last relay negative pole normally-closed contact are formed the output of batteries jointly, supply power to power consumption equipment.
The utility model is not limited to above embodiment, and every other execution modes that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope of protecting of the utility model equally.
