Abstract: The present application relates to a battery module. The battery module includes a battery group and an insulating plate. The battery group includes a bus bar and a plurality of battery units, each battery unit includes a tab which includes a connecting segment and a bending segment. The insulating plate includes a plurality of plate assemblies, and the adjacent plate assemblies are connected through a connecting plate. There is an obtuse angle between each plate assembly and the connecting plate connected thereto. Each connecting segment passes through a guiding groove, and the bending segment and the bus bar are fixed and connected. The guiding groove can adjust the altitude of the tab as it passes through the insulating plate. The bending segment can be connected to the bus bar, then the process requirements can be met with a small space, which improves the energy density of the battery module.

IPC: H01M50/691
Abstract: This application discloses a battery cabinet. A drain assembly is disposed at the bottom of a cabinet body of the battery cabinet. The drain assembly includes a drain valve. A valve spool and a magnetic object are disposed in the drain valve. The valve spool is movably disposed in the drain valve and has a first state of sealing the drain valve or a second state of opening the drain valve. The magnetic object generates a magnetic force to keep the valve spool in the first state, and the valve spool stays in the second state when a downward force applied to the valve spool is greater than a preset value. Therefore, draining is started when the water accumulated on the valve spool reaches a specified weight, and a new valve spool is automatically closed after the water is drained.
