Wherein, baffle is for controlling the charge/discharge of portable power source, and described baffle has a charge port and delivery outlet, and the charge port described in this is the interface to portable power source charging with external device; The interface of described delivery outlet (mobile phone, pad, MP3, PSP etc.) power supply to mobile device, digital product etc. as portable power source is exactly usually said USB interface.
Chinese patent ZL201320005755.1 discloses a kind of portable power source, and the built-in lithium battery for discharging and recharging of this portable power source can be cylinder type lithium battery or poly-lithium battery.As improvement, described cylinder type lithium battery or poly-lithium battery can be replaced, and portable power source is at least equipped with the lithium battery of two identical category, model, and user is in routine work and life, can, respectively by all charged two above lithium batteries, use in case of need.
But two lithium batteries in above-mentioned patent are to connect in inside, can not cut off.
In addition, the battery low for electric weight do not have automatic safety device, thereby has the problem of putting, and battery core is caused to damage.
Low in order to overcome portable power source power supplying efficiency when electric weight is lower, damage portable power source battery core, situation about even cannot charge, is necessary existing portable power source to improve.
Utility model content
And technical problem to be solved in the utility model is: a kind of portable power source is provided, can connects at any time between the same money lithium battery of this portable power source, cut off at any time, and can prevent that battery from crossing and put.
The utility model solves described technical problem by following technical proposals: a kind of portable power source; comprise the lithium battery with battery core, baffle and the glue shell of charge/discharge circuit; charging inlet is connected with charging circuit; delivery outlet is connected with output control circuit; wherein: described portable power source is provided with docking port; the docking port that accesses two portable power sources by connecting line forms battery pack, and described battery pack is connected with electrical quantity sensor.Docking port described in the utility model is circumscribed, between lithium battery, can connect at any time, cuts off at any time, easy to use; Electrical quantity sensor, for detection of battery core electric weight, is closed output when battery core electric weight is low, prevents the overdischarge amount of battery core, and battery core is played a protective role.
On such scheme basis, for use is observed with being convenient to, between described lithium battery group and charging circuit and output control circuit, be connected to electric-quantity display device, described battery pack sequentially connects electrical quantity sensor, over-charge protective device, charged state display to charging inlet, forms charging circuit; Described battery pack sequentially connects overcurrent protective device, output state display to output interface forms output control circuit and connects.
Or described charged state display and output state display are integral type charged state display/output state electric-quantity display device, can show charged state in charging circuit, or show output state in output control circuit.
Superiority of the present utility model is: between lithium battery, can connect at any time, cut off at any time, and easy to use; Electrical quantity sensor can detect battery electric quantity in time, effectively prevents from that battery from crossing to put, and also can improve supplying power for outside efficiency.
Refer to Figure of description below, the utility model is further described.
