Abstract
The utility model discloses a lithium ion battery, which comprises a battery cell (1), a protective circuit board (2) and an external shell (3), wherein the battery cell (1) and the protective circuit board (2) are arranged in the external shell (3); a flat cable interface (2,1) is arranged on the protective circuit board (2); the anode and the cathode of each monocell (1.1) in the battery cell (1) are correspondingly connected onto monomer contacts on the flat cable interface (2,1)one to one; a test interface (2.2) is arranged on the external side of the external shell (3); and the monomer contacts on the test interface (2.2) are correspondingly connected with the monomer contacts on the flat cable interface (2,1) one to one. A battery can be tested or detected without dismantling the external shell of the lithium ion battery.
Description
Technical field
The utility model relates to a kind of lithium ion battery.
Background technology
See also shown in Figure 1ly, the lithium ion battery of prior art comprises electric core 1 ', protection circuit plate 2 ' and shell 3 '.Described protection circuit plate 2 ' is used for lithium ion battery is carried out additives for overcharge protection, over, overcurrent and short-circuit protection etc.Described electric core 1 ' and protection circuit plate 2 ' are installed in the described shell 3 '.Described protection circuit plate 2 ' is provided with winding displacement interface 2.1 '; the both positive and negative polarity of the every joint monocell 1.1 ' in the described electric core 1 ' all is connected in the described winding displacement interface 2.1 ', and the both positive and negative polarity of every joint monocell 1.1 ' is connected on the monomer line contact on the described winding displacement interface 2.1 ' correspondingly.Because the protection circuit plate and the electric core of the lithium ion battery of prior art are installed in the shell; therefore; the operating position of battery in needing the test battery group; maybe need the single battery of battery pack is charged separately; or one of them or several battery of battery pack are when occurring need detecting when unusual; we need described shell is taken apart; test or detect at protective circuit plate winding displacement interface; perhaps disconnect being connected of monocell and winding displacement interface; single battery in the battery pack is tested or detected; difficulty that this has just increased test greatly or has detected, and in dismounting cell, may change the structure of battery pack and phenomenon such as cause that battery pack is short-circuited.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of need not just to take its shell apart can test or detect battery pack lithium ion battery.
Technical solution of the present utility model is, a kind of lithium ion battery with following structure is provided, and comprises electric core, protection circuit plate and shell; Described electric core and protection circuit plate are installed in the described shell; Described protection circuit plate is provided with the winding displacement interface; the both positive and negative polarity of the every joint monocell in the described electric core is connected on the monomer line contact on the described winding displacement interface correspondingly; the described shell outside is provided with test interface, and the monomer line contact on the described test interface is connected with monomer line contact on the described winding displacement interface correspondingly.
After adopting above structure, the utility model lithium ion battery compared with prior art has the following advantages:
Because the shell of the utility model lithium ion battery is provided with test interface, monomer line contact on the described test interface is connected with monomer line contact on the described winding displacement interface correspondingly, therefore, when need detect when unusual appears in one of them or several battery of the operating position of battery or battery pack in needing the test battery group, need not the shell of lithium ion battery is taken apart, as long as test interface is connected with the interface of external test macro, just can tests or detect the battery of electric core; When need the single battery of battery pack being charged separately,, operate quite easy as long as just be connected and charge to this single battery with the corresponding contact of this single battery with on charger interface and the test interface.
