Abstract

The invention discloses a battery module which comprises a plurality of battery cells, a pole connector, a temperature control air-guiding device and a module frame, wherein the pole connector is used for connecting the poles of the battery cells so as to connect the battery cells in series and / or in parallel; the temperature control air-guiding device is used for covering the pole connector and is equipped with a first opening, a second opening and a third opening; air enters from the first opening, the second opening is used for exhausting air, and the third opening is formed in a position corresponding to the pole connector, so that air can pass by and be in contact with the pole connector in the process of flowing from the first opening to the second opening; and the module frame is used for accommodating the battery cells. In the battery module, the temperature control air-guiding device is designed for the key parts for temperature control, namely, the poles of the battery cells and the pole connector, so that the temperature control effect can be promoted and the time consumption of temperature adjustment can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electrical energy devices, and in particular to battery modules. Background technique [0002] The energy provided by a single battery is limited. To meet the electric energy demand of the electric vehicle power battery system or the energy storage battery system of the national grid, it is necessary to connect a large number of single batteries in series and parallel to form a group, and then connect these battery modules Groups are then connected in series and parallel to meet people's needs to a certain voltage level and capacity level. However, in order to meet sufficient power requirements in a limited space, a large number of single batteries are often densely packed in the battery box. In the actual operating environment, the battery system needs to have the characteristics of large capacity and high rate discharge, and a series of chemical reactions will occur during the cha...
