The upper large capacity used, high power lithium ion cell, the loading space on vehicle is limited, and number of battery cells needed for vehicle is larger,
Battery is close-packed arrays connection.When vehicle is transported under the different driving conditions of the checkers such as high speed, low speed, acceleration, deceleration
When row, battery can be discharged with different multiplying, amount of heat be generated with different heat rates, in addition accumulated time and spacial influence
Uneven heat aggregation is will produce, it is complicated and changeable so as to cause battery pack operating ambient temperature.Due to the intensive of cell body that generate heat
It puts, certainty heat aggregation in intermediate region is more, and fringe region is less, and the temperature increased in battery pack between each monomer is uneven
Weighing apparatus, aggravates each battery module monomer internal resistance and capacity inconsistency.If long time integration, can cause percentage of batteries overcharge and
Overdischarge, and then service life and the performance of battery are influenced, and cause security risk.
Invention content
It is reasonable for structure the purpose of the present invention is to provide a kind of Vehicular dynamic battery group, it can effectively take away in battery pack
The heat that is generated in charge and discharge of battery core, so that battery core is reached thermal balance during charge and discharge.
To achieve the above object, the technical scheme is to design a kind of Vehicular dynamic battery group, including shell and
The head cover being seal-installed on shell, the shell include bottom plate and the side plate that is arranged around bottom plate surrounding, the bottom plate and side
The accommodating chamber for accommodating several power battery cores is collectively formed in plate, is equipped in the accommodating chamber two neighboring dynamic for separating
The baffle of power battery core；The base plate interior is equipped with coolant circuit, and bottom plate side is equipped with and is connected to coolant circuit
Water inlet and water outlet, the coolant circuit is disc-shaped snakelike, which includes several straightways and be located at
Several bending sections at several straightway both ends, several described straightways it is arranged in parallel and with several power battery cores
It corresponds, each straightway is located at the underface of corresponding power battery core, and the bending section is for being connected to two neighboring straight line
Section.By using said program, the heat that the battery core in battery pack is generated in charge and discharge can be effectively taken away, battery is made
Body reaches thermal balance during charge and discharge.
Preferably, the bottom plate lower surface is equipped with the reinforcing rib of several inner hollows, several reinforcing rib parallels
It arranges and is corresponded with several bending sections, each reinforcing rib one end is connected to corresponding bending section, and each reinforcing rib is curved positioned at correspondence
Between two straightways of tune connection, the reinforcing rib is internally provided with water-stop sheet.By the way that the reinforcing rib of inner hollow is arranged, make
The integral strength of bottom plate gets a promotion；In addition, water-stop sheet is arranged inside reinforcing rib, flow through bending section cooling water will along every
Water plate side flows into inside reinforcing rib, and under the action of follow-up hydraulic pressure, cooling water will bypass water-stop sheet and along the water-stop sheet other side
It flows out inside reinforcing rib, returns in coolant circuit.By using said program, film-cooled heat is expanded, to improve cooling
Effect.
Preferably, support leg is respectively equipped at the angle of the bottom plate lower surface four, the cross sectional shape of each support leg is L-type shape
Shape.By using said program, convenient for keeping flat shell.
Preferably, the bottom plate, side plate, baffle, reinforcing rib and support leg are by plastics integrated injection molding.By using upper
Scheme is stated, the assembling procedure of battery pack is simplified, also, makes shell entirety loss of weight, and without between each part and adjacent
Insulating film or insulating cement are set between power battery core.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the schematic diagram of bottom plate of the present invention.
Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is further described.Following embodiment is only
For clearly illustrating technical scheme of the present invention, and not intended to limit the protection scope of the present invention.
The technical solution that the present invention embodies is：
