Abstract
The utility model provides a rechargeable lithium cell device, which has a cell box device, wherein the inside of the cell box device consists of a lithium cell and a rechargeable circuit board, and a direct current (DC) port and cell contact piece groups are reserved at the outer part of the cell box device. The positive and the negative poles of the lithium cell are respectively led out through two wires to be connected to the rechargeable circuit board, and three wires are led out from the rechargeable circuit board to be connected to the three cell contact piece groups which are respectively the positive of the cell, a power ground and the positive pole of a DC power supply. The charging and power supplying are completely separated. The cell box is installed on a portable device, the device judges whether the cell box is charged or not according to whether the positive pole of the DC power supply is electrified or not, so a power supply mode is selected. The device disclosed by the utility model is charged by only using an alternating current (AC) adapter, so a multi-cell allocation scheme is realized, a special charger does not need to be separately designed and produced, and the charging is convenient, so the backup power supply of the large power portable device is greatly ensured.
Description
Technical field
The utility model particularly about a kind of electric supply installation that is used for the bigger portable set of power consumption, is a kind of chargeable lithium cell device about field of portable electronic apparatus concretely.
Background technology
Portable electric appts is because its portable, applied range is subjected to a large amount of consumers' welcomes.In order to satisfy the function that it is carried, this kind equipment generally need be equipped with battery as power supply.In the numerous kinds battery, lithium battery has rated voltage height, long service life, characteristics such as in light weight, is suitable as the electric supply installation of portable electric appts.
For the bigger portable set of power consumption, the cruising time of lithium battery is relatively more crucial.Therefore under the specific occasion, provide reserve battery very necessary.Then the form of primary cell, reserve battery and charging modes seem very crucial.
The general finished product of high-capacity lithium battery (more than the 3000mAh) is less, and most forms of drawing with electric core parallel connection, positive and negative lead wires occur, and are unfavorable for the replacing of field apparatus battery.Simultaneously, how charging also becomes problem to reserve battery.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of lithium battery equipment that can charge simultaneously and power is provided, and is used for the power supply of the bigger portable set of power consumption.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Chargeable lithium cell device of the present utility model, its battery case 101 inside are made up of lithium battery 102, charging circuit board 103, and charging DC interface 104, battery contact group 105 are left in the outside.The both positive and negative polarity of lithium battery 102 uses two leads to draw and is connected to charging circuit board 103, draws three leads on the charging circuit board 103 and is connected to battery contact group 105, is respectively positive pole, power supply ground and the DC positive source of battery.Charging is independent fully with power supply.Whether battery case 101 is installed on the portable set, have electricity whether to judge battery case 101 in charging by equipment according to the DC positive source, thus the mode of selection power supply.
Compared with prior art, the beneficial effects of the utility model are:
The charging of equipment only need use AC adapter can realize that many batteries are equipped with scheme, and does not need to design and produce separately special charger.Charging simultaneously is convenient, has guaranteed that largely the back-up source of big power consumption portable set is supplied with.
Description of drawings
Fig. 1 is the inner structural representation of forming of battery case.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Figure 1 shows that the chargeable lithium cell device, its battery case 101 inside are made up of lithium battery 102, charging circuit board 103, and DC interface 104, battery contact group 105 are left in the outside.DC interface 104 can be used for the AC adapter charging, and charging does not conflict with power supply, can carry out simultaneously.The both positive and negative polarity of lithium battery 102 uses two leads to draw and is connected to charging circuit board 103, draws three leads on the charging circuit board 103 and is connected to battery contact group 105, is respectively positive pole, power supply ground and the DC positive source of battery.Whether battery case 101 is installed on the portable set, have electricity whether to judge battery case 101 in charging by equipment according to the DC positive source, thus the mode of selection power supply.
Above embodiment only is used to illustrate the utility model, but not is used to limit the utility model.
