Description
Technical field
The utility model relates to a portable power source, particularly relates to a kind of string and puts and fill portable power source.
Background technology
Power supply is very extensive daily life, and power supply in use can come the external loading power supply is needed again it is charged after the electric weight in the power supply is finished using by discharge.For power supply, its conversion efficiency and itself temperature rise and convenience are very crucial indexs.For some powerful portable power sources, these characteristics are even more important especially.And existing power supply can not both be taken into account the safety of charging, took into account again the efficient of when discharge.
The utility model content
The utility model wants the technical solution problem to be, provide a kind of can realize with externally discharge after the series connection of the battery pack of portable power source, with after the battery pack parallel connection of portable power source to its portable power source that charges.
For solving above technical problem, the technical solution of the utility model is: a kind of string is put and is filled portable power source, comprise the first battery pack, the second battery pack, charging circuit module and discharge circuit module, its key is: be provided with double-point double-throw switch between described two Battery pack groups and described charging circuit module and described discharge circuit module.
As improvement one of the present utility model, the positive pole of described first battery pack of A1 termination of described double-point double-throw switch, the negative pole of described first battery pack of A2 termination of described double-point double-throw switch, the B1 end of described double-point double-throw switch and the negative pole of described the second battery pack, the negative pole of the negative pole of charging circuit module and described discharge circuit module is connected, the B2 end of described double-point double-throw switch and the positive pole of described the second battery pack, the C1 end of described double-point double-throw switch and the positive pole of discharge circuit module connect, and the C2 end of described double-point double-throw switch is connected with the positive pole of described charging circuit module.
As improvement two of the present utility model, described string is put and is filled portable power source and also comprises the connection in series-parallel detection module.
Further improve as the utility model, described string is put and is filled portable power source and also comprises control module.Described control module comprises the MCU controller.
Further improve as the utility model, put and fill at described string and also be provided with connecting interface on the portable power source.
By implement the present invention desirable following beneficial effect:
The pattern that the utility model adopts string to put and fill switches to state in parallel with battery pack when charging, so that charge efficiency improves, save energy resource consumption, effectively reduces again the temperature rise of portable power source itself simultaneously, improves the fail safe of charging.When discharge battery pack is switched to series connection, improve its supply power voltage, allow voltage conversion circuit can adopt reduced output voltage, the electric current of whole circuit is diminished, line loss reduces, and has saved energy content of battery loss, has also reduced simultaneously heating and temperature rise.The string put and and fill two kinds of working methods by switching by double-point double-throw switch, simple and convenient.The utility model implementation is simple, be skillfully constructed, and this electricity-saving function is very practical, is with a wide range of applications.
