A kind of electric bicycle lithium ion battery
Technical field
The utility model belongs to the battery technology field, relates in particular to a kind of electric bicycle lithium ion battery.
Background technology
Kuomintang-Communist is sold out 2,100 ten thousand electric bicycles in 2008 according to statistics, in global marketing market, has 90% all to be that Chinese buy.Sales volume in 2009 is above 2,640 ten thousand; The year rate of growth of China's Mainland Market Growth rate 2010-2012 is about 20%, other in regional market year rate of growth will be up to 30-40%, the basis estimates according to this; Global electric bicycle market scale will reach 4,940 ten thousand in 2015; And use lithium ion battery increasingly high as the ratio that the energy provides, particularly after the lead contamination poisoning, all electric bicycle factories are all at the electric bicycle of developing lithium ion battery.
But the electronic bicycle battery of lithium ion on the market drives the power except providing to bicycle now, can not be used for other aspects basically, and range of application is narrower.
The utility model content
In view of this, the utility model provides a kind of lithium ion battery, solves the technical problem of lithium ion battery applications narrow range in the prior art.
The utility model is achieved in that
A kind of electric bicycle lithium ion battery comprises shell and is arranged at the electric core in this shell that said shell is provided with USB interface, and said USB interface and electric core are electrically connected through circuit.
The quantity of said USB interface is one or more.
Said lithium ion battery is the electric bicycle lithium ion battery.
The voltage of said lithium ion battery is 24V~48V.
The capacity of said lithium ion battery is 5AH~20AH.
The utility model electric bicycle lithium ion battery is provided with USB interface on shell, through circuit this USB interface is connected with the battery battery core circuit, makes the range of application of lithium ion battery increase greatly; Through a plurality of USB interfaces are set, make lithium ion battery can realize a plurality of application simultaneously.
Description of drawings
Fig. 1 is the utility model embodiment electric bicycle lithium ion battery structure sketch map.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1; Fig. 1 shows the utility model embodiment electric bicycle lithium ion battery structure sketch map; This electric bicycle lithium ion battery comprises shell 1; Be arranged at the electric core (not shown) in this shell 1, also be provided with USB interface 2 on this shell 1, said USB interface 2 is electrically connected through circuit with said electric core.Like this, this electric bicycle lithium ion battery is provided with USB interface on shell, through circuit this USB interface is connected with the battery battery core circuit, makes the range of application of electric bicycle lithium ion battery increase greatly; Through a plurality of USB interfaces are set, make the electric bicycle lithium ion battery can realize a plurality of application simultaneously.Wherein, Through the USB interface 2 that is electrically connected with electric core is set; Can so that no matter this lithium ion battery of electric bicycle be in operation still in inactive state; Can give mobile electronic product through USB interface 2,, even can illumination be provided for the LED that is equipped with USB interface etc. like chargings such as mobile phone, MP3, GPS, notebook computers.Therefore, improve the range of application of electric bicycle lithium ion battery greatly, changed the electric bicycle lithium ion battery of special purpose into multiduty stand-by power supply.
Preferably, as the embodiment of the utility model, the voltage of this electric bicycle lithium ion battery is 24V~48V, for example, and 24V, 36V or 48V; The capacity of this lithium ion battery is 5AH~20AH, for example, and 5AH, 10AH and 20AH.
Preferably, as the embodiment of the utility model, the quantity of above-mentioned USB interface is one or more, for example, 2,3,4 etc.
Concrete, the not restriction of the circuit of above-mentioned electrical connection USB interface 2 and electric core can realize being electrically connected between this USB interface and the electric core both positive and negative polarity getting final product.
The position that this USB interface 2 is provided with on shell 1 is restriction not, preferably is arranged on shell 1 position that keeps to the side.USB interface 2 is arranged on shell 1 position that keeps to the side, can makes lithium ion battery more attractive in appearance on the one hand, also can not exert an influence on the other hand the normal power supply of lithium ion battery to electric bicycle.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
