Abstract

The utility model provides an energy-storage battery pack. The battery pack comprises a shell, an airflow feeding device and a plurality of battery pack module units, wherein the plurality of battery pack module units are arranged up and down, and a space allowing airflow to pass through is formed between adjacent battery pack module units; one side of the space formed between the adjacent battery pack module units is communicated with the airflow feeding device; shells of the battery pack module units forming the space are air inlet shells, and outer-side shells of the two outermost-side battery pack module units are air outlet shells; a plurality of air separating plates are vertically arranged on the air inlet shells, and are parallel to two sides of the communication positions between the airflow feeding device and the air inlet shells. According to the energy-storage battery pack, airflow can flow in the battery pack regularly, the temperature difference can be reduced by 30-65 percent, and the service life of the battery pack can be prolonged.

Description

Energy-storage battery bag
Technical field
The utility model relates to a kind of energy-storage battery bag.
Background technology
Traditional power brick volume is large, air-flow enters battery pack by the fresh air inlet in inlet shell, mobile in battery pack of air-flow do not have rule, through the exhaust vent on air-out housing, flow out, the air flow rate that each exhaust vent flows out is more random, cause the temperature difference of battery pack inside larger, cause indivedual battery temperatures too high, finally affect the serviceability of whole power brick.
Utility model content
The utility model aims to provide the energy-storage battery bag that a kind of temperature difference is lower.By following scheme, realize:
A kind of energy-storage battery bag, comprise shell, air-flow feeder, several battery module unit, several battery module unit are up and down to be arranged, between adjacent cell pack module unit, form the space that can make air-flow pass through, one side in the space forming between described adjacent cell pack module unit is communicated with air-flow feeder, forming the housing that forms the battery module unit in space between described adjacent cell pack module unit is inlet shell, the outside housing of two battery module unit of outermost is air-out housing, in described inlet shell, be vertically installed with some wind isolation boards, the parallel air-flow feeder that is positioned at of wind isolation board is communicated with the both sides of position with inlet shell.
Further, for the better balanced pressure of controlling airflow passes battery pack, on described wind isolation board, be provided with several ventilation holes.
Energy-storage battery bag of the present utility model, in inlet shell, be vertically installed with wind isolation board, and the parallel air-flow feeder that is positioned at of wind isolation board is communicated with the both sides of position with inlet shell, after merging, adjacent inlet shell formed an air-flow flow channel between wind isolation board, in addition, on wind isolation board, be provided with several ventilation holes, the ventilation hole of flowing through on wind isolation board after air-flow enters air-flow flow channel, again through the battery pack of flowing through of the fresh air inlet in inlet shell, from the exhaust vent of air-out housing, flow out, make air current flow compared with rule, also can adjust air flow rate by adjusting the size of ventilation hole on wind isolation board, so finally can make the temperature difference in power brick reduce by 30%～65%, extend the useful life of power brick.

Embodiment
Embodiment is just in order to illustrate a kind of implementation of the present utility model, not as the restricted explanation to the utility model protection range.
embodiment 1
A kind of energy-storage battery bag, as shown in Figure 1, comprise shell 1, two fans 2, two Battery pack pack module unit 3, two Battery pack pack module unit 3 are up and down to be arranged, between battery module unit 3, form the space 4 that can make air-flow pass through, one side in the space 4 forming between battery module unit 3 is communicated with fan 2, and fan 2 is sent into convection current; The housing that forms the battery module unit 2 in above-mentioned space 4 is inlet shell 5, the outside housing of two battery module unit 3 is air-out housing 6, as shown in Figure 2, in inlet shell 5, be vertically installed with four wind isolation boards 7, on wind isolation board, be provided with several ventilation holes 8, the parallel fan 2 that is positioned at of wind isolation board 7 is communicated with the both sides of position with inlet shell 5.Structural representation after neighbouring inlet shell merges as shown in Figure 3.
Energy-storage battery bag of the present utility model, after merging, adjacent inlet shell forms an air-flow flow channel between wind isolation board, the air-flow that fan blows out is through air-flow flow channel, ventilation hole process from wind isolation board, fresh air inlet inlet shell flows into battery pack, exhaust vent from air-out housing flows out again, and the size of adjusting ventilation hole adjusts air flow rate, makes air-flow flowing compared with rule in energy-storage battery bag.Use 3C electric current to discharge and recharge power brick, the temperature difference that test obtains in power brick is 3.8 ℃, compares with existing power brick, and the temperature difference has reduced by 50%.

Claims (2)

1. an energy-storage battery bag, comprise shell, air-flow feeder, several battery module unit, several battery module unit are up and down to be arranged, between adjacent cell pack module unit, form the space that can make air-flow pass through, one side in the space forming between described adjacent cell pack module unit is communicated with air-flow feeder, forming the housing that forms the battery module unit in space between described adjacent cell pack module unit is inlet shell, the outside housing of two battery module unit of outermost is air-out housing, it is characterized in that: in described inlet shell, be vertically installed with some wind isolation boards, the parallel air-flow feeder that is positioned at of wind isolation board is communicated with the both sides of position with inlet shell.
2. energy-storage battery bag as claimed in claim 1, is characterized in that: on described wind isolation board, be provided with several ventilation holes.
