The lithium secondary battery of a described two standard cell pattern is characterized in that: this standard cell is to be selected from one of them of No. three standard cells and No. four standard cells.
The lithium secondary battery of a described two standard cell pattern, it is characterized in that: the discharge voltage of this lithium battery is between 4.2 volts to 3.6 volts, and this reduction voltage circuit is reduced to the discharge voltage of this lithium battery about 3 volts.
The lithium secondary battery of a described two standard cell pattern is characterized in that: this low electric-quantity monitoring circuit detects the lithium battery electric weight and has put soon when electric, and this reduction voltage circuit can become low-voltage with voltage transitions, and electronic product can be sensed.
The lithium secondary battery of a described two standard cell pattern, it is characterized in that: this reduction voltage circuit is voltage transitions to be become 2 volts low-voltage.
The present invention comprises a housing, is equiped with the standard lithium battery of a two standard cell size in it, and this two lithium battery is to link with parallel way; In housing, also be provided with a printed circuit board (PCB); it is to comprise a reduction voltage circuit; give step-down in order to discharge voltage with this lithium battery; one charging circuit is that this lithium battery is charged; and discharge and the charging of a protective circuit in order to protect this lithium battery arranged, and a low electric-quantity monitoring circuit is a dump energy of detecting this lithium battery.
The invention has the advantages that:
The lithium secondary battery of a two standard cell pattern proposed by the invention is to utilize special circuit design to make the discharge voltage of a two standard lithium battery be compatible to the voltage of general electronic products; And then make this lithium secondary battery have in light weight, self-discharge rate is low, capacitance is big, the little and long advantage that lithium secondary battery such as life-span itself promptly has that recycles influenced by ambient temperature, also simultaneously with characteristics such as standard cell generality height, convenient purchases.
Below the detailed as explanation by the specific embodiment conjunction with figs., when the effect that is easier to understand purpose of the present invention, technology contents, characteristics and is reached.
Description of drawings
Fig. 1 is a schematic appearance of the present invention.
The standard lithium battery annexation schematic diagram that Fig. 2 uses for the present invention.
Fig. 3 is a box structure schematic diagram of the present invention.
Embodiment
The present invention is that the lithium battery with two parallel connections wires up with a housing and is made into the lithium secondary battery of a two standard cell pattern; and in housing the installing one printed circuit board (PCB); to utilize the circuit control on the printed circuit board (PCB) and the start of protection lithium battery, making lithium proposed by the invention two batteries is the advantages that have standard cell and lithium secondary battery simultaneously concurrently.
Fig. 1 is a schematic appearance of the present invention, and as shown in the figure, the lithium secondary battery of this pair standard cell pattern is to comprise a housing 10, and it is the size that is designed to an approximate Double standard cell, makes in its battery case that can be placed in an electronic product; It in this housing 10 the rechargeable type standard lithium battery 12 that is equiped with two parallel connections, its annexation as shown in Figure 2, this two lithium battery 12 is to form with the relation of parallel connection to be electrically connected, and its whole specification is the size of a two standard cell, for example: No. three standard cells (AA Size) or No. four standard cells (AAA Size), commonly used is No. three standard cells; The conductiving point of this two lithium battery 12 is to expose outside this housing, with as external contact 14, is electrically connected to electronic product and its required electric power is provided to provide.
