Description
Technical field:
The utility model relates to the battery technology field, refers in particular to power battery pack.
Background technology:
Current battery is widely applied to various fields, and its compound mode is Protean, and " low-carbon (LC) " life is all being advocated in the whole world, and this has also just promoted developing rapidly of ev industry.And the electrokinetic cell key position of electric automobile just, because become the most important thing of research electric automobile.
Power battery pack and power brick are to be coupled together through different series-parallel systems by several cells in use.As cell can be any one secondary cell.Because the operating current of electrokinetic cell is very big, battery pack produces a large amount of heats in the process of using, and therefore needs to rely on extraneous heat abstractor that heat is distributed, otherwise influences the chemical property of battery and have potential safety hazard.If the battery heat radiation is inhomogeneous, will cause having certain temperature difference between each battery, use the inconsistency of the chemical property of this battery that will cause for a long time, thereby influence the life-span and the security performance of whole battery group.
The power brick of being made up of cylindrical battery at present mainly contains insert row formula structure and parallel arrangement (seeing shown in Figure 1).With air-cooled form is example, and well-known, the cooling effect of electric core receives the size of air quantity and the Influence of Temperature of wind.For the electric core of insert row formula and parallel arrangement, because a part of heat transferred that front-seat electric core produced is in cooling air, thereby the temperature of whole cooling air can increase, and is therefore poor near back row's electric core cooling effect.The temperature rise of local electric core is too high, causes excessive temperature differentials in the whole battery group.It seems that from some cases the temperature difference of battery pack is up to 30 degree.Will shorten the life-span of whole battery group so greatly, limit the performance of other battery performances simultaneously.
Therefore it is necessary designing a kind of novel can guaranteeing inhomogeneity battery pack of dispelling the heat.
The utility model content:
The purpose of the utility model is exactly the deficiency that exists to prior art and a kind of have Homogeneouslly-radiating effect, power battery pack that security performance is high are provided.
To achieve these goals, the technical scheme of the utility model employing is:
Power battery pack, its include cell cover, battery lower cover and be located at cell cover and the battery lower cover between several cylinders shape electricity core, several electric cores are arranged in trapezoidal electric core group by trapezoidal mode.
As a kind of improvement of the utility model power battery pack, said cell cover and battery lower cover insulating material for processing by plastic cement, rubber or pottery; Perhaps be metal structure, the outside of metal structure coats insulating material.
As a kind of improvement of the utility model power battery pack, between said cell cover and the battery lower cover through buckle be connected, screw connection, welding or bonding mode be fixedly connected, structure is firm, and is easy to assembly.
As a kind of improvement of the utility model power battery pack, said trapezoidal electric core group is stacked by the electric core of many rows and combines.
As a kind of improvement of the utility model power battery pack, the electric core of adjacent two rows staggers or parallel arrangement each other in the said trapezoidal electric core group, is preferably the mode that staggers each other.
As a kind of improvement of the utility model power battery pack, in the said trapezoidal electric core group respectively arrange electric core quantity by after be discharged into the front row and successively decrease by row.
As a kind of improvement of the utility model power battery pack, the two ends of the electric core of every row are combined into the cell row group through a cell cover, a battery lower cover respectively in the said trapezoidal electric core group, and are easy to assembly.
As a kind of improvement of the utility model power battery pack, be fixedly connected through screw connection, buckle connection, splicing or welding manner between adjacent two row's cell row groups, structure is firm, and is easy to assembly.
The utility model beneficial effect is: its include cell cover, battery lower cover and be located at cell cover and the battery lower cover between several cylinders shape electricity core; Several electric cores are arranged in trapezoidal electric core group by trapezoidal mode; Regulate effectively and balance two kinds of factors of temperature of cooling agent and cooling agent to the influence of battery pack radiating effect, reduce the temperature difference in the battery pack, have the Homogeneouslly-radiating effect; Good heat dissipation effect, security performance is high.
