By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
Embodiment one:
See also Fig. 2, Figure 2 shows that a kind of charging device in the present embodiment, comprise power connector 1, first charging circuit 2, first battery 3, second battery 4 and controller 5; The input of first charging circuit 2 is connected with external power supply by power connector 1, and the output of first charging circuit 2 is connected with first battery 3, second battery 4 and first battery in parallel 3; Controller 5 is used for obtaining the state information of first battery 3 and/or second battery 4, controls the switch of the charge tunnel of first charging circuit 2 according to the state information of obtaining.The operating current of present embodiment middle controller 5 can be provided by first battery 3 that is in discharge condition and/or second battery 4; Certainly, in charging process, also can be provided by first charging circuit 2,5 outputs with first charging circuit 2 of controller this moment are connected.
By charging device shown in Figure 2 as can be known, because first battery 3 directly is connected with the output of first charging circuit 2 with second battery, 4 backs in parallel, 5 switches of just controlling the charge tunnel of first charging circuit 2 according to the state information of first battery 3 and second battery 4 of controller, do not need to switch or select charge tunnel, during charging, first charging circuit 2 can be spontaneous to first battery 3 and the charging of second battery 4, do not need the switching of special Logic control module and variable connector control charge tunnel, can avoid filling the switching charge tunnel and cause charging device work disorder, even the situation of damage device, can improve reliability and the fail safe of charging circuit, reduce and make, use cost.During discharge, first charging circuit, 2 no-outputs, first battery 3 and 4 on second battery can be spontaneous power to controller, do not need the switching of special Logic control module and variable connector control power supply passage yet, can avoid switching supplying cell and cause two batteries to switch dangerous situations such as moment generation voltage jump, shake, surge current even of short duration power down, can further improve reliability and the fail safe of charging circuit.
In the present embodiment, the state information of first battery 3 and second battery 4 comprises the electric weight that whether battery is in place, battery is current etc.; Controller 5 specifically can pass through the battery detecting module, and for example voltameter, Coulomb meter, voltmeter, ammeter etc. obtain the state information of battery.

Be that example is carried out a complete explanation with a complete charging, discharge process below:
Charging device is connected by as shown in Figure 2 annexation; If the battery electric quantity of current first battery 3 and second battery 4 is all opened threshold value less than default charging, controller 5 collects after this information, transmit control signal to first charging circuit 2, open the charge tunnel of first charging circuit 2, after first charging circuit 2 will be carried out step-down etc. by the electric current of power connector input and handle this moment, to first battery 3 and 4 chargings of second battery, in charging process, first charging circuit 2 is also optionally to controller 5 power supplies; In charging process, when controller 5 detects first battery 3 and the current electric weight of second battery 4 and all turn-offs threshold value greater than default charging, then can send control information to first charging circuit 2, turn-off the charge tunnel of first charging circuit, at this moment first charging circuit, 2 no-outputs.Because first charging circuit, 2 no-outputs, the circuit of this moment then is in discharge condition, first battery 3 and 4 spontaneous the powering to controller of second battery; For example, suppose the voltage height of voltage ratio second battery 4 of current first battery 3, then mainly powered to controller by first battery 3, and that when the current power supply capacity of first battery 3 is sufficient first battery 3 also can be simultaneously spontaneous to 4 chargings of second battery.
Above charge and discharge process can not assert that just for the ease of understanding the exemplary explanation that the utility model is done concrete enforcement of the present utility model is confined to these explanations; For example, when open the charge tunnel of first charging circuit 2 for controller 5, specifically can be set to have only when the electric weight of first battery 3 and second battery 4 is all opened threshold value less than charging, just open, then need the state information of first battery 3 and second battery 4 this moment, as long as when the electric weight that also can be set to one of them battery is opened threshold value less than charging, just opens, then only need this moment the state information of first battery 3 or second battery 4 to get final product, etc.; Again for example, when turn-off the charge tunnel of first charging circuit 2 for controller 5, also can be set to have only when the electric weight of first battery 3 and second battery 4 all turn-offs threshold value greater than charging, just turn-off, then need the state information of first battery 3 and second battery 4 this moment, as long as when the electric weight that also can be set to one of them battery is opened threshold value greater than charging, just turn-offs, then only need this moment the state information of first battery 3 or second battery 4 to get final product, etc.; Perhaps, except above-mentioned set-up mode, also can adopt battery electric quantity information and battery whether the combination of information such as in place the unlatching of first charging circuit 2 and the condition of shutoff etc. are set, present embodiment illustrates no longer one by one.
Embodiment two:
In embodiment one scheme shown in Figure 2, second battery 4 is directly in parallel with first battery 3, in discharge process, when the voltage of voltage ratio first battery 3 of second battery 4 is high, then second battery 4 can to 3 chargings of first battery, thereby can cause energy loss in controller 5 power supplies; For fear of the problems referred to above, present embodiment is on the basis of scheme shown in Figure 2, increased flow restricter 6, see also shown in Figure 3, second battery 4 directly is connected with first battery 3 by flow restricter 6, and flow restricter 6 can stop electric current to flow to first battery 3 from second battery 4, and then avoids above-mentioned energy loss, further improve efficiency of resource, can also guarantee the priority that battery uses simultaneously.
In the scheme shown in Figure 3, flow restricter 6 is except above-mentioned effect, also can be separately be used for flowing to from first battery 3 and first charging circuit 2 current peak of second battery 4, avoid the excessive variety of issue that causes of electric current, and then improve fail safe and the reliability of charging device.Preferably, flow restricter 6 can be set in the present embodiment according to the applied environment of reality and possess at least a in above-mentioned two kinds of functions.
Embodiment three:
No. one charging circuit all only is provided among embodiment one and the embodiment two, therefore can have a charging circuit is the situation of two battery charge simultaneously, in order to improve the flexibility of charge efficiency and charging circuit control, present embodiment also can be on the basis of above-mentioned two embodiment, increase by No. one charging circuit again, specifically see also Fig. 4 and shown in Figure 5:
See also Fig. 4, the scheme shown in this figure is on scheme shown in Figure 2 basis, and the input that has increased by second charging circuit, 7, the second charging circuits 7 is connected with the output of power connector 1, and output is connected with second battery 4; Controller 5 also can be controlled the switch of the charge tunnel of second charging circuit 7 according to the state information of first battery 3 and/or second battery 4; Simultaneously, controller 5 can be selected to be connected with the output of first charging circuit 2 and/or second charging circuit 7, with in charging process, realizes that first charging circuit 2 and/or second charging circuit 7 are controller 5 power supplies.Controller 5 also still can be connected with second charging circuit 7 by control bus, and then sends corresponding control signal by control bus to second charging circuit 7.
In this scheme, what first charging circuit 2 and second charging circuit 7 can walk abreast simultaneously is first battery 3 and 4 chargings of second battery, also can be separately first battery 3 and/or 4 power supplies of second battery simultaneously, therefore can increase charging device to the flexibility of charging control.For example, when controller detected first battery 3 and second battery 4 and all needs to charge, controller can select to open simultaneously the charge tunnel of first charging circuit 2 and second charging 7, also can select a unlatching in first charging circuit 2 and second charging circuit 7.
See also Fig. 5, the scheme shown in this figure is on scheme shown in Figure 3 basis, has increased by second charging circuit 7, on scheme shown in Figure 4, has then increased flow restricter 6; The output by first battery 3 or first charging circuit 2 that can only be unidirectional owing to flow restricter 6 restriction electric currents flows to second battery 4, stop electric current to flow to first battery 3 from the output of second battery 4 and second charging circuit 7, in this scheme, first charging circuit 3 both can charge to first battery 3, also can charge to second battery 4, but second charging circuit then can only charge to second battery 4, can not charge to first battery 3.
For example: when controller 5 detects first battery 3 and second battery 4 and all needs to charge, controller can be opened the charge tunnel of first charging circuit 2 and second charging circuit 7 simultaneously, and what this moment, first charging circuit 2 and second charging circuit 7 can walk abreast simultaneously charges to first battery 3 and second battery 4; Controller 5 also can only be opened the charge tunnel of first charging circuit 2, and be that first battery 3 and second battery 4 charge by first charging circuit 2 separately this moment then.Again for example, when detecting when having only second battery 4 to charge, then controller 5 can select to open simultaneously the charge tunnel of first charging circuit 2 and second charging circuit 7, and this moment, first charging circuit 2 and second charging circuit 7 can be simultaneously to 4 chargings of second battery; Controller 5 also can be selected a unlatching in first charging circuit 2 and second charging circuit 7, then having only No. one charging circuit this moment is 4 chargings of second battery.Again for example, when detecting when having only first battery 3 to charge, then controller 5 selects to open the charge tunnel of first charging circuit 2, and this moment, first charging circuit 2 was to 3 chargings of first battery.
Embodiment four:
