Abstract
The present application relates to a battery module and a method and equipment for manufacturing the same, a battery pack, and an apparatus. The battery module includes Type 1 battery cells and Type 2 battery cells connected in series; the Type 1 battery cells and the Type 2 battery cells satisfy the following criteria: 1.01×C1/C2≤N2≤1.25, and C1<C2, where N2 is a battery charge balance rate of the Type 2 battery cells; C1 and C2 are respectively capacities of the Type 1 battery cells and the Type 2 battery cells. By a reasonable combination of chemical systems of battery cells with different capacities, the battery module of the present application can have good safety and stability while achieving the battery cells with different capacities each having high energy output characteristics during charging and discharging, thereby increasing the energy density of the battery module.
