Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of many group storage batterys grouping charging device simultaneously, comprise storage battery 1, wire 2, switch 3 and snap joint 4, be connected by wire 2 series connection between described each storage battery 1, described wire 2 is provided with lead-out wire 5, and the other end of described lead-out wire 5 is connected with one end of snap joint 4; The other end of described snap joint 4 is provided with intelligent charger 6, and described intelligent charger 6 is made up of jointly switch matrix 7, charhing unit 8 and controller 9, and the other end of described snap joint 4 is connected with switch matrix 7 by wire 2; Described switch matrix 7, to be connected by wire 2 between charhing unit 8 and controller 9.
Further, the input voltage of described intelligent charger 6 is 220V alternating current.
Further, the quantity of described storage battery 1 is 5 groups.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, be five with the storage battery quantity comprised in storage battery group to be illustrated.
As shown in Figure 1, in figure, A point, B point, C point, D point are connected to the tie point on two series connection storage battery wires, respectively has a lead-out wire 5 to be connected with snap joint 4 from above 4.
As shown in Figure 2, intelligent charger 6 comprises three parts, comprises switch matrix 7, multiple charhing unit 8 and controller 9, is connected between switch matrix 7, multiple charhing unit 8, controller 9 three by corresponding wire 2.
As shown in Figure 3, during charging, utilize snap joint 4, make wherein A point and A

0switch disconnects, thus completes charging process.
By that analogy, the storage battery quantity no matter in storage battery group has how many, uses the present invention, all can realize charging to the grouping of many group storage batterys simultaneously, and storage battery in storage battery group is more, and charge efficiency is higher.Should be appreciated that present embodiment is only used to the present invention is described, instead of in order to limit the scope of the invention.
In the technical program, by the closed of controller 9 control switch matrix 7 breaker in middle 3 and disconnection, storage battery charge circuit in storage battery group is divided into two groups: the charge circuit conducting of odd number group storage battery, the charge circuit of even number set storage battery disconnects, thus first the odd number group storage battery forming loop is charged simultaneously, after electricity is full of, controlled by controller 9, the odd number group storage battery charge circuit being full of electricity is disconnected, uncharged even number set storage battery charge circuit closes, and antithesis array storage battery charges simultaneously, when even number set storage battery is full of electricity, control even number set storage battery charge circuit by controller to disconnect, and complete charging, finally realize the quick charge of storage battery group.
In technique scheme, carry out the closed of respective switch in control switch matrix 7 by controller and cut-off, thus realize the grouping charging of storage battery group.
Above-mentioned multiple charhing unit under the control of the controller, successively charges to odd number group and even number set storage battery, and therefore, two groups of storage batterys use identical charhing unit, charhing unit number minimum comprise by storage battery group the half of storage battery quantity.
When above-mentioned odd number group or even number set storage battery charge sequentially, each storage battery in two groups has separately independently charhing unit and charge circuit, and therefore, each storage battery in two groups is charging simultaneously and unaffected each other when charging.
When above-mentioned odd number group and even number set storage battery charge sequentially, the charge circuit of odd number group and even number set storage battery can not conducting simultaneously, therefore, unaffected each other when odd number group and even number set storage battery grouping charging.
Multiple charhing units in above-mentioned intelligent charger part are commercially available matured product, by charhing unit, corresponding with newly-designed switch matrix and controller be connected and close be integrated, common composition intelligent charger part.
Above-mentioned intelligent charger; 220V or the 380V low-voltage AC that its input power adopts market common; except can realizing aforesaid function; can also realize automatically controlling the charging process of battery pack; the defencive function such as realize the overcurrent of charging process, overvoltage, overcharge, and have timing, soon, at a slow speed charging select and grouping timing charge function.
The present invention also can set two groups of charging intervals according to stopping for charging time length, and motor vehicle realizes charging on schedule, achieves electric vehicle accumulator grouping equalizing charge, can avoid the infringement of storage battery.
The present invention designs ingenious, easy to use, and fast and safely, fundamentally solve electric motor car charging rate slow, an inefficient difficult problem, concerning prior art, is once great technological innovation, has good market prospects and development space.
By reference to the accompanying drawings the preferred embodiments of the disclosure and embodiment are explained in detail above, but the present invention is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the inventive concept of the premise.
