The utility model content
The utility model technical problem to be solved is to solve rechargeable battery to have only a kind of EBI form, the problem that versatility is relatively poor usually.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted provides a kind of rechargeable battery; Comprise housing and be built in the control circuit board in the housing; Said housing is provided with and is used to plug into the interface of power devices circuit and a plurality of light-emitting diodes and control button that are used to show battery dump energy; Said control circuit board is provided with cell energy management chip bq2060 and electric weight reading of data interface, and said electric weight reading of data interface comprises HDQ, NTC and CLK pin, and the HDQ16 pin of cell energy management chip bq2060 links to each other with said HDQ pin through first resistance; The SMBD pin of cell energy management chip bq2060 links to each other with said HDQ pin through second resistance, and the SMBC pin of cell energy management chip bq2060 links to each other with said CLK pin through the 3rd resistance.
In such scheme, the interface of the said power devices circuit that is used to plug into comprises two first, second openings that are opened in respectively on the said housing adjacent side, and said first opening and said second opening intersect on the arris of said housing.
In such scheme, be respectively equipped with some spacing draw-in grooves on four sides facing each other on the said housing, the said spacing draw-in groove on the adjacent side is vertical each other.
In such scheme, said housing is respectively equipped with the portion that picks and places that is used to mate finger on two relative sides, and the said portion of picking and placeing is that pit or boss and surface are provided with coarse lines.
The utility model carries out HDQ and SMBD through second resistance multiplexingly, makes rechargeable battery have two kinds of communication bus interface, i.e. SMBus EBI and 1-wire EBI have improved the versatility of rechargeable battery.
In addition; The interface of power devices circuit of being used on the housing to plug into comprises two first, second openings that are opened in respectively on the housing adjacent side; And first opening and second is opened on the arris that intersects at housing, is being respectively equipped with some spacing draw-in grooves on four sides facing each other on the housing, and the spacing draw-in groove on the adjacent side is vertical each other; Make rechargeable battery can adapt to horizontal and vertical two kinds of direction of insertion, the battery compartment of instrument can flexible design.
Description of drawings
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the circuit diagram of the utility model control circuit board.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
Like Fig. 1, shown in Figure 2; The utility model comprises housing 1 and is built in the control circuit board in the housing 1 that housing 1 is provided with a plurality of be used for the plugging into interface 11 of power devices circuit and a plurality of light-emitting diodes 12 and control button 13 (corresponding to the S1 of circuit diagram) that are used to show battery dump energy.
Housing is respectively equipped with the portion that picks and places 16 that is used to mate finger on 1 two relative sides, picks and places portion 16 and is provided with coarse lines for pit or boss and surface, is convenient to picking and placeing of rechargeable battery.
As shown in Figure 3; Control circuit board is provided with cell energy management chip bq2060 and electric weight reading of data interface; Electric weight reading of data interface comprises HDQ, NTC and CLK pin; The HDQ16 pin of cell energy management chip bq2060 links to each other with the HDQ pin through first resistance R 16, and the SMBD pin of cell energy management chip bq2060 links to each other with the HDQ pin through second resistance R 17, and the SMBC pin of cell energy management chip bq2060 links to each other with the CLK pin through the 3rd resistance R 18.Cell energy management chip bq2060 is in order to detect battery electric quantity; In this chip; SMBC and SMBD are the SMBus interface based on the 2-wire agreement, and HDQ16 is the HDQ interface based on the 1-wire agreement, because the communication protocol of two kinds of buses is different; Through R17 HDQ and SMBD are carried out multiplexingly, can make rechargeable battery have two kinds of communication bus interface.V1-V4 is a light-emitting diode, and in order to the pilot cell dump energy, R1-R4 is respectively its current-limiting resistance; Battery electric quantity is divided into 4 equal portions, and when a LED lamp was bright, the expression battery dump energy was 25%; When 4 LED are complete when bright, the expression dump energy is 100%, and promptly battery electric quantity is full; When having only a lamp flicker, when all the other lamps went out entirely, the expression battery electric quantity was empty; C2, V5 are voltage-regulating circuit, so that for cell energy management chip bq2060 power supply is provided.When battery in the charge or discharge process, cell energy management chip bq2060 follows the tracks of and detects battery electric quantity all the time, when button S1 pressed, cell energy management chip bq2060 indicated through lighting LED according to current battery dump energy.The control of light-emitting diode and voltage-regulating circuit are the conventional design of this area, repeat no more at this.
