Embodiment
The present invention has disclosed a kind of portable battery that flings, referring to the theory diagram shown in Fig. 1, it comprises the input interface that connects DC power supply, the storage battery of storage of electrical energy, the output interface that connects load, between the positive pole of input interface and battery positive voltage, be connected in series a charge control module of controlling charging current, battery positive voltage connects the positive pole of output interface, the negative pole of input interface and output interface is ground connection respectively, between battery terminal negative and ground, be connected in series electronic switch, described storage battery connects a protection module that detects battery tension and charging and discharging currents, protection module connecting electronic switch controller break-make.
During charging, with power line or data wire, input interface is connected to (generally adopting the direct current of five volts) with external power supply adaptor, direct current process input interface and charge control module are transported to storage battery and store.After the sufficient electric power of storage battery, battery can be carried, when the electronic products such as mobile phone need to charge, the output interface of this device can be connected to the charging inlet of electronic product, without re-using power supply adaptor, the direct current in storage battery directly charges to electronic product.Referring to the preferred embodiment shown in Fig. 2, J1 is for connecting the input interface of external dc power, and J2 is the output interface of connecting electronic product, and R3 is a thermistor.U1 is the chip in charge control module, and U1 manages the size of charging current.The 4th pin (VCC) of U1 connects the positive pole of input interface, and the 3rd pin (BAT) is to charge in batteries, and the 6th pin is by the second resistance R 2 ground connection.By setting the resistance of R2, set the size of charging current.Fig. 3 shows the circuit diagram of protection module, and protection module chip U2 the 5th pin connects the positive pole of storage battery by the 4th resistance R 4, and the 6th pin connects the negative pole of storage battery, and the 5th, the 6th pin is power input and cell voltage collection terminal.The 2nd pin (CSI) is by the 5th resistance R 5 ground connection, for detection of charging and discharging currents size.In better fact Example, electronic switch consists of the metal-oxide-semiconductor field effect transistor of two series connection.Q1 in Fig. 3 is this pair of metal-oxide-semiconductor field effect transistor, and Q1 is serially connected between storage battery and ground.When normally discharging and recharging, the 1st pin (OD) of U2 and the 3rd pin (OC) output high level, metal-oxide-semiconductor Q1 conducting, the negative pole of storage battery is connected with ground, and the loop of complete, discharges and recharges normally and carries out.When U2 detects storage battery and is full of, the OD of U2, OC pin output low level, Q1 cut-off, charge circuit disconnects, and realizes over-charge protective.When U2 detect battery discharging electric discharge too much, cell voltage is when too low, the OD of U2, OC pin output low level, Q1 cut-off, discharge loop disconnects, and realizes Cross prevention.When U2 detects charging and discharging currents when excessive, the OD of U2, OC pin output low level, Q1 cut-off, charging and discharging circuit disconnects, and realizes overcurrent and short-circuit protection.
In better fact Example, charge control module connects a power supply indicator and charged state indicator light.Referring to Fig. 2, D1 is a red colored lamp, as power supply indicator; D2 is a green light, as charged state indicator light.One end of D1 and D2 is connected respectively the 1st pin and the 5th pin of U1, and the other end of D1 and D2 also connects the rear positive pole that is connected input interface by the first resistance R 1.When this device does not connect external dc power, red light green light does not all work; When this device just connects DC power supply, when red, green light does not work, and represents to charge; When battery is full of electricity, red light green light is all bright, represents that battery is full, and charging finishes.
In better fact Example, described input interface adopts micUSB interface.
Above embodiment is only for illustrating, non-providing constraints.Anyly do not depart from the application's spirit and category, and the equivalent modifications that it is carried out or change all should be contained among the application's claim scope.
