Embodiment
Below will explain content of the present invention by embodiment, embodiments of the invention and be not used to restriction the present invention can must implement in any specific environment as described embodiments, application or particular form.Therefore, the explanation about embodiment is only explaination object of the present invention, and is not used to limit the present invention.Need expositor, in following examples and accompanying drawing, the element relevant to non-immediate of the present invention omits and does not illustrate, and in accompanying drawing, each interelement size relationship is only and asks easy understanding, and is not used to limit actual ratio.
Please refer to shown in Fig. 2, according to the integrated portable power source 20 of one of present pre-ferred embodiments, comprise a power storaging unit 21, power control unit 22, first output/input unit 23 and second output/input unit 24.
Power storaging unit 21 comprises a battery pack, and it is secondary cell, and meaning is rechargeable battery.In the present embodiment, battery pack is such as but not limited to lithium polymer battery (Li-polymer) or lithium ion battery (Li-ion).
Power control unit 22 and power storaging unit 21 are electrically connected.Power control unit 22 at least comprises 221, one, Charge Management loop boosting loop (boost circuit) 222 and a reduction voltage loop (buck circuit) 223.Charge Management loop 221 and the first output/input unit 23 are electrically connected.Boosting loop 222 is electrically connected with Charge Management loop 221.Reduction voltage loop 223 is electrically connected with boosting loop 222 and power storaging unit 21 respectively.Wherein, Charge Management loop 221, in order to restriction charging and discharge voltage, to guarantee that being no more than safe voltage causes battery explosion, or when cell voltage is too low, cuts off and exports, avoid shorter battery life.
In order to by battery full charging, boosting loop 222 therefore must be utilized in circuit first charging voltage to be drawn high to certain high levle, the step-down of recycling reduction voltage loop 223 is to charge to battery.
Current lithium often adopts three sections of mise-a-la-masse methods from the charger of ion battery, i.e. precharge mode (Pre-Charging Mode), constant-current charge (Fast Charging Mode), constant-voltage charge pattern (Constant Voltage Mode).Below lift an example to illustrate, it is 2.5V that lithium ion battery stops discharge voltage.The electricity of battery is first detected, if cell voltage is greater than 3V, then by normal mode charging before charging; If cell voltage is lower than 3V, be then referred to as precharge mode with small area analysis (being about the constant current mode charging current of 10%) charging, allow the passivating film dissolved under being in deep discharge conditions reduce.In addition, when battery over-discharge can, also may disengage part copper metal and cause short circuit at anode, if now carry out forcing charging that battery will be caused overheated with high electric current, pre-charging stage then can avoid this phenomenon to occur.Charge by normal constant current mode again after being charged to 3V.
When cell voltage is greater than 3V, then by normal mode charging, when initial, cell voltage is with slope rising faster, and the increase stored along with battery electric power, the cell voltage rate of rise can progressively reduce, and when rising to close to 4.2V, the constant-current charge stage terminates.Charger changes with 4.2V constant-voltage charge, and when determining the charging of voltage stage, voltage is almost constant, but charging current continuous decrease.When charging current drops to a certain value, start timer, after one section of counting and timing cut-off, complete charge, completes charging formula.
Shown in Fig. 2, the first output/input unit 23 is electrically connected with power control unit 22, and has a triggering loop 231.Triggering loop is operate on a first mode or one second pattern.

In other words, when triggering loop 231 and operating on first mode, integrated portable power source 20 is in charge mode, be such as charged by the first output/input unit 23 pairs of power storaging units 21 by power supply unit, or by power storaging unit 21, the mobile device being connected to the second output/input unit 24 charged.When triggering loop 231 and operating on the second pattern, integrated portable power source 20 is in data transmission pattern, is namely the electronic installation being connected to the first output/input unit 23 and the second output/input unit 24 is carried out data transmission.
In the present embodiment, the first output/input unit 23 and the second output/input unit 24 are for meeting the output/input unit of USB standard.
Shown in Fig. 3, it is the circuit diagram example illustrating the first output/input unit 23 and the second output/input unit 24.Wherein, the first output/input unit 23 has a splicing ear, and it has four branch connecting pin P11, P12, P13, P14, and the second output/input unit 24 has a splicing ear, and it has four branch connecting pin P21, P22, P23, P24.Wherein, pin P11, P14 is for triggering loop 231.In the present embodiment, when voltage is not bestowed in triggering loop 231, then trigger loop 231 and be in first mode, and when triggering loop 231 and being bestowed voltage, then trigger loop 231 and be in the second pattern.
In addition, in the present embodiment, charge protocol loop 241 and data agreement loop 242 are respectively a pressure divider circuit, but its dividing potential drop and the voltage drop obtained is different.
In other embodiments, corresponding to different application products, charge protocol loop 241 such as can be designed to short circuit shown in Fig. 3.
In sum, according to the integrated portable power source of one of the present invention, it integrates charge protocol loop and data agreement loop, and by triggering the pattern in loop, and activation charge protocol loop or data agreement loop.When charge protocol loop is enabled, then the first output/input unit can connect mobile device to charge, and when data agreement loop is enabled, then numerical data can transmit between the first output/input unit and the second output/input unit.
The above embodiments are only used for exemplifying enforcement aspect of the present invention, and explain technical characteristic of the present invention, are not used for limiting protection category of the present invention.Anyly be familiar with this operator and the arrangement of unlabored change or isotropism can all belong to the scope that the present invention advocates, the scope of the present invention should be as the criterion with claims.
