Description

Dynamical lithium-ion battery packs

Technical field

It the utility model is related to cell art, more particularly to a kind of dynamical lithium-ion battery packs.

Background technology

With the development of science and technology, lithium-ion-power cell is in mobile phone, portable computer, video camera, photograph The part such as machine instead of conventional batteries.High capacity lithium ion battery is tried out in electric automobile, will turn into 21 century electronic vapour One of major impetus power supply of car, it is applied in terms of artificial satellite, Aero-Space and energy storage.

However, the radiating effect of current lithium-ion-power cell heat abstractor is unsatisfactory.In addition, lithium ion power is electric Pond water inlet can cause to use, or even potential safety hazard be present.

In summary, the dynamical lithium-ion battery packs, in practice in the presence of it is inconvenient the problem of, it is therefore necessary to changed Enter.

Utility model content

The purpose of this utility model is to provide the one kind of radiating effect well, with water inlet early warning and output end counnter attack connection function Dynamical lithium-ion battery packs.

To achieve the above object, using following technical scheme：

A kind of dynamical lithium-ion battery packs, including some battery units, fin, BMS circuit boards, humidity sensor, shell Body；The battery unit is contacted by thermal grease with fin；The BMS circuit boards respectively with battery unit, humidity sensor Device is electrically connected with；The battery unit, fin, BMS circuit boards, humidity sensor are placed in housing cavity.

It is preferred that the Li-ion batteries piles include two battery units, each battery unit include first support, second Frame, battery；Battery is placed in by the first support with second support to be clamped between the two.

It is preferred that the fin cross section is T-shaped construction；The T-shaped horizontal end of fin is bonded with housing；Two electricity Pool unit is located at the two sides at the T-shaped perpendicular end of fin respectively.

It is preferred that the first support, second support are that honeycomb is poroid；The thermal grease passes through second support honeycomb Hole contacts with battery end, fin respectively.

It is preferred that the housing includes upper casing, shell, lower casing；The upper casing and lower casing are connected together with shell respectively.

It is preferred that the lower casing bottom sets the anti-reverse lead-out terminal being electrically connected with BMS circuit boards.

It is preferred that the Li-ion batteries piles also include a LED light on upper casing, itself and BMS circuit boards are electric Property connection, for system intake early warning.

Using such scheme, the beneficial effects of the utility model are：

1) radiating effect is good：Take the poroid design of support honeycomb+thermal grease heat conduction to fin, fin by with Shell Aluminum Drum, which fully contacts, carries out heat conduction outward；Particularly battery pack fast charge when, can be fast by high heat caused by heavy-current discharge Speed exports to outside；The poroid design of honeycomb of support, effectively ensure the temperature consistency of each battery；

2) water inlet warning function：When internal battery pack is intake, humidity sensor will transmit a signal to BMS, system Signal early warning can be carried out in Surface L ED indicator lamps；

3) it is anti-reverse：This battery pack connection terminal realizes that the rotation of 180 degree any direction is all unrestricted, prevents reversal connection from bringing Battery failures even accident.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to figs. 1 to shown in 3, a kind of dynamical lithium-ion battery packs, including some battery units 1, fin 2, BMS circuits Plate 3, humidity sensor, housing 4；The battery unit 1 is contacted by thermal grease with fin 2；The BMS circuit boards 3 divide It is not electrically connected with battery unit 1, humidity sensor；The battery unit 1, fin 2, BMS circuit boards 3, humidity sensor It is placed in the inner chamber of housing 4.

Wherein, the Li-ion batteries piles include two battery units 1, and each battery unit 1 includes first support 11, second Support 12, battery 13；Battery 13 is placed in by the first support 11 with second support 12 to be clamped between the two.The fin 2 Cross section is T-shaped construction；The horizontal end of fin 2T types is bonded with housing 4；Two battery unit 1 is located at fin 2T respectively The two sides at the perpendicular end of type.The first support 11, second support 12 are that honeycomb is poroid；The thermal grease passes through second support 12 honeycomb holes contact with the end of battery 13, fin 2 respectively.The housing 4 includes upper casing 41, shell 43, lower casing 42；On described Shell 41 and lower casing 42 are connected together with shell 43 respectively.The bottom of lower casing 42 sets the counnter attack being electrically connected with BMS circuit boards 3 Connect lead-out terminal 5.The Li-ion batteries piles also include a LED light on upper casing 41, and itself and BMS circuit boards 3 are electric Property connection, for system intake early warning.

Utility model works principle：

1) radiate：Battery 13 is carried out clamping by battery unit 1 using the poroid first support 11 of honeycomb and second support 12, Thermal grease is through the honeycomb hole of the second support 12 contact end of battery 13 and fin 2；During battery pack use, battery 13 On the one hand caused heat is distributed by the poroid first support 11 of honeycomb, another aspect thermal grease passes through second support For the poroid thermal contact conductance of 12 honeycombs on fin 2, fin 2 carries out heat conduction outward by fully being contacted with the Aluminum Drum of shell 43；It is special It is not that high heat can export to outside rapidly caused by heavy-current discharge when battery pack carries out fast charge；In addition, support honeycomb The uniformity of the temperature of poroid each battery 13 of design effective guarantee；

2) water inlet early warning：When humidity sensor senses internal battery pack water inlet, BMS (electricity will be transmitted a signal to Pond management system) circuit board 3, system can be in the progress signal early warning of Surface L ED indicator lamps, prompting user internal battery pack water inlet；
