Abstract
A battery module, a power battery pack and a vehicle are provided. The battery module comprises n cells. At least two surfaces of the cell are respectively provided with a first positive terminal and a first negative terminal, and a second positive terminal and a second negative terminal. The n cells are arranged side by side in series. The cell (100) has a length L and a thickness T, where L meets 600 mm<L≤1300 mm, and L and T meet 23≤L/T≤200.
