Novel battery module structure

Abstract

The invention discloses a novel battery module structure. The novel cell module structure comprises a battery module, the battery module is formed through the series connection and the laminating arrangement of the anodes and the cathodes a plurality of lamination electric cores, two ends of each of the lamination electric cores are respectively provided with an electric core tab, on end of the battery module is sleeved in a pole column end insulation sheath, the other end of the battery module is sleeved in an insulation sheath, tab openings used for the traversing of the electric core tabs are arranged in each of the pole column end insulation sheath and the insulation sheath, and the pole column end insulation sheath is provided with an anode column and a cathode column which are connected with the anode and the cathode of the battery module; and the battery module is wrapped in a module shell, and one end side surface of the module shell is provided with first installation holes for the traversing of the anode column and the cathode column. The novel battery module structure has the advantages of simple operation, convenient and fast installation, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a novel battery module structure. Background technique [0002] At present, lithium-ion batteries are widely used in fields such as electric vehicles. In order to achieve higher voltage or larger capacity of power batteries, it is often necessary to connect multiple cells in series or in parallel to form a battery pack. Laminated cells have the advantages of light weight, small thickness, large capacity, small internal resistance, flexible design, good safety, and high current charging and discharging. However, the outer packaging of laminated cells is a layer of protective film, which is prone to puncture under the action of external force, and a reliable external structure is required to protect the cells from external damage. Moreover, the lugs of laminated batteries are sheet-shaped, and the thickness is about 0.3mm. In the environment of vehicle vibration, the str...

Problems solved by technology

However, the outer packaging of laminated cells is a layer of protective film, which is prone to puncture under the action of external force, and requires a reliable external structure to protect the cells from external damage

Moreover, the lugs of laminated batteries are sheet-shaped, and the thickness is about 0.3mm. In the environment of vehicle vibration, the stress caused by vibration is easy to concentrate on the connection part of the tabs, resulting in a decrease in the reliability of the connection between the batteries.
