Abstract
The utility model discloses a lithium ion battery pack used for an electrical vehicle, comprising a box body, a plurality of lithium ion batteries contained in the box body, a conducting connecting plate which is connected with all the lithium ion batteries in series or in parallel, and a cover plate arranged on the box body; and the central axes of all the lithium ion batteries arranged in the lithium ion battery pack on the electrical vehicle are horizontal. When in running process of the electric vehicle, the lithium ion batteries in the lithium ion battery pack used for the electrical vehicle can not move vertically along the central axes to collide with the box body due to bumpiness, thus prolonging the service life of the lithium ion batteries and improving the safety performance of the lithium ion battery pack.
Description
Technical field
The utility model relates to a kind of lithium ion battery bag, especially a kind of used for electric vehicle lithium ion battery bag with good safety energy.
Background technology
That lithium ion battery has is in light weight, energy storage is big, power is big, pollution-free, advantages such as the life-span long, the self discharge coefficient is little, temperature wide accommodation, therefore is subjected to people's favor gradually, has also progressively replaced other conventional batteries in the electric automobile field.
In order to satisfy batteries of electric automobile high voltage and high-octane needs, the cell polar ear of some lithium ion batteries need be carried out serial or parallel connection usually, make up then and form the lithium ion battery bag in the casing of packing into.In order in time to distribute the heat that lithium ion battery in the use produces, between the lithium ion battery, need to leave certain clearance between lithium ion battery and the casing.
But in the prior art, when the lithium ion battery bag was installed on the electric automobile, each lithium ion battery all adopted vertical placement, and promptly the central axis of each lithium ion battery in the lithium ion battery bag is vertical setting.Because the existence in heat radiation gap, in the electric automobile during traveling process, lithium ion battery in the lithium ion battery bag can pitch along central axis with electric automobile, easy and casing produces bump and causes the block of lithium ion battery to damage, thereby reduced the useful life of lithium ion battery, when serious even security incident such as can blast.
In view of this, necessary provide a kind of have good safety can used for electric vehicle lithium ion battery bag.
The utility model content
The purpose of this utility model is: a kind of used for electric vehicle lithium ion battery bag with good safety energy is provided.
To achieve these goals, the utility model provides a kind of used for electric vehicle lithium ion battery bag, it comprises: a casing, somely be contained in lithium ion battery in the casing, with the conductive connection plates of each lithium ion battery serial or parallel connection, an and cover plate that is installed on the casing, be installed in the lithium ion battery bag on the electric automobile central axis level of each lithium ion battery.
As a kind of improvement of the utility model lithium ion battery bag, the central axis of described each lithium ion battery is vertical with the longitudinal axis of electric automobile.
As a kind of improvement of the utility model lithium ion battery bag, described casing is provided with several accepting grooves by some dividing plates, and described each lithium ion battery is contained in respectively in the corresponding accepting groove.
As a kind of improvement of the utility model lithium ion battery bag, between described lithium ion battery and the described casing, between described lithium ion battery and the described dividing plate, leave certain clearance between described each lithium ion battery.
As a kind of improvement of the utility model lithium ion battery bag, described cover plate is removably installed on described casing.
As a kind of improvement of the utility model lithium ion battery bag, described cover plate is provided with some through holes.
With respect to prior art, when the utility model used for electric vehicle lithium ion battery bag is installed on the electric automobile, the central axis level of each lithium ion battery, vertical with the longitudinal axis of electric automobile.Therefore, in the driving process of electric automobile, each lithium ion battery can not move up and down along central axis, can be not impaired with casing collision because of jolting, thus prolonged useful life of lithium ion battery, improved the security performance of lithium ion battery bag.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model used for electric vehicle lithium ion battery bag and useful technique effect thereof are elaborated, wherein:
Figure 1 shows that the perspective exploded view of the utility model used for electric vehicle lithium ion battery bag.
Figure 2 shows that the user mode schematic diagram after the utility model used for electric vehicle lithium ion battery bag is installed on the electric automobile, do not show electric automobile among the figure.
Embodiment
See also illustrated in figures 1 and 2, the utility model used for electric vehicle lithium ion battery bag 10 comprises: a casing 20, several are installed in the lithium ion battery 30 in the casing 20, a pair of conductive connection plates 40 that is used to electrically connect each lithium ion battery 30, and a cover plate 50 that is removably installed on casing 20.
In the assembling process of lithium ion battery bag 10, at first, each lithium ion battery 30 is placed corresponding accepting groove 204 respectively, need simultaneously to guarantee: between the sidewall of each lithium ion battery 30 and casing 20, between each lithium ion battery 30, and leave certain clearance between each lithium ion battery 30 and the dividing plate 202, in time to distribute the heat that produces in lithium ion battery 30 uses, guarantee the useful life and the security performance of lithium ion battery 30; Then, conductive connection plates 40 is placed on the lithium ion battery 30, be connected with external circuit after the cell polar ear (not shown) of each lithium ion battery 30 is pressed the predetermined way serial or parallel connection; At last, with cover plate 50 stably fastenings on casing 20.
During actual the use, can the aforementioned lithium ion battery bag 10 that assembles be installed on the electric automobile by mode well known to those skilled in the art, the central axis of each lithium ion battery 30 is parallel with horizontal plane substantially, preferably can be vertical with the longitudinal axis of electric automobile.
Be different from prior art, after the utility model used for electric vehicle lithium ion battery bag 10 is installed on the electric automobile, the central axis level of each lithium ion battery 30 in the lithium ion battery bag 10, vertical with the longitudinal axis of electric automobile, therefore, in the driving process of electric automobile, lithium ion battery 30 can not move up and down along central axis, difficult because of jolting and casing 20 collision damages, thus the useful life of lithium ion battery 30 prolonged, improved the security performance of lithium ion battery bag 10.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
