Abstract
The utility model relates to a device for charging batteries connected in series, comprising a controller and a plurality of battery packs; wherein the controller is connected with an AC/DC (Alternating Current/Direct Current) module and a DC/DC module, both the AC/DC module and the DC/DC module are connected with an external power supply, the plurality of battery packs are connected in series with each other, a master switch is arranged between the controller and the battery packs connected in series; the controller is respectively connected in series with the individual battery pack, a branch switch is arranged between the controller and the each individual battery pack. The device of the utility model has the beneficial effects that: the device detects the battery having a lower voltage in the battery packs connected in series to charge, so as to enable the voltage of the battery to reach an average voltage, then the device performs detection and charging again, by performing the dynamic recycle, energy balance is achieved, at the same time, the heat of the battery can be reduced, and a service life of the battery also can be prolonged.
Description
Technical field
The utility model relates to a kind of series-connected cell charging device.
Background technology
Development along with science and technology, the application of battery enlarges rapidly, the application that particularly consists of large-capacity battery pack by multiple batteries has very large market, no matter be in the energy storage field or in electric utility, the prospect of battery all is expected, but battery is in production process and use procedure, has the shortcomings such as discharge difference and radiating effect be poor, and reduced the useful life of battery.
The utility model content
The purpose of this utility model provides a kind of series-connected cell charging device, and it is slow to overcome in the existing product each storage battery energy time for balance, produces the larger deficiency of heat.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of series-connected cell charging device, comprise controller and some battery pack, described controller is connected with AC/DC module and DC/DC module, the AC/DC module is connected with the DC/DC module and is connected external power source, its feature is, mutually be connected in series between described some battery pack, be provided with master switch between controller and the battery pack of connecting; Described controller is connected in series with independent battery pack respectively, is equipped with switch-dividing between controller and the independent battery pack.
The beneficial effects of the utility model are: a kind of series-connected cell charging device that the utility model provides, charge by detecting a batteries weak in the series battery, make it reach average voltage, and then detect, charge, so dynamic circulation makes it reach balancing energy, can reduce simultaneously the heat of battery, prolong its useful life.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the circuit theory diagrams of the described a kind of series-connected cell charging device of the utility model embodiment.
Among the figure:
1, controller; 2, battery pack; 3, AC/DC module; 4, DC/DC module; 5, external power source; 6, master switch; 7, switch-dividing.
Embodiment
As shown in Figure 1, the described a kind of series-connected cell charging device of the utility model embodiment, comprise controller 1 and some battery pack 2, described controller 1 is connected with AC/DC module 3 and DC/DC module 4, AC/DC module 3 is connected with the DC/DC module and is all connected external power source 5, mutually be connected in series between described some battery pack 2, be provided with master switch 6 between controller 1 and the battery pack 2 of connecting; Described controller 1 is connected in series with independent battery pack 2 respectively, is equipped with switch-dividing 7 between controller 1 and the independent battery pack 2.
During use, by alternating current or the direct current of AC/ DC module 3 and 4 pairs of external power sources of DC/DC module 5 inputs, be converted into and be convenient to controller 1 it is controlled voltage and current, controller 1 is selected intelligent controller.During charging, the master switch 6 closed series batteries 2 of giving charge, seek the lower batteries group 2 of voltage with Time Controller 1, by regulation and control switch-dividing 7, it is carried out additional charge, when this batteries group electromotive force when not being minimum, intelligent controller is selected again, batteries group 2 to minimum energy is carried out additional charge, and when wherein a batteries group 2 reached rated voltage, cut-out master switch 6 stopped the charging to battery pack 2, intelligent charge still keeps single battery group 2 is selected charging, until all battery pack 2 when all reaching rated voltage, then stop charging, thereby reach dynamic equilibrium.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
