Description
Technical Field
The utility model relates to the technical field of power batteries, in particular to a power battery pack.
Background
In the field of new energy storage, a heat dissipation structure of a power battery pack is a key design affecting the service life and safety of a battery. At present, the heat dissipation modes of the battery pack mainly comprise an air-cooled mode and a water-cooled mode. Although the water-cooled heat dissipation effect is better and the energy consumption is lower, the air-cooled heat dissipation device is still widely used due to the simplicity of an air-cooled system, low maintenance cost and higher reliability. The heat dissipation effect of the air-cooled battery pack mainly depends on the structural design of the air duct. In order to improve the heat dissipation effect, the heat dissipation device can be realized by increasing the heat exchange area, reducing the thermal resistance of the heat conduction interface and increasing the wind speed.
The battery cell is formed by winding and laminating a positive plate, a negative plate and a diaphragm which are made of metal materials. In the side direction of the battery cell, a part with poor thermal conductivity such as a diaphragm, an active material and the like exists between the pole piece layers. The pole is composed of metal pole pieces, and has good heat conduction performance. Therefore, when the battery cell works, the heat conduction in the direction of the pole is obvious, and the temperature of the pole relative to the side face of the battery cell is higher.
The power battery in the prior art has the following technical problems. Firstly, a cold air path generally enters a section bar between the battery cells, takes heat on the large surface of the battery cells away, enters an independent air duct between two battery packs, and is finally sucked and taken out by a fan. However, this approach ignores the cooling of the terminal posts and tabs on the upper surface of the cell, which may result in local excessive temperatures of the cell that affect the performance and life of the battery.
Therefore, there is a need for an improvement to the above-described problems to change the current situation.
