  "textContent": "Aspects of the disclosure include battery cells with constant compression force mechanisms. An exemplary vehicle includes an electric motor and a battery pack electrically coupled to the electric motor. The battery pack includes a plurality of battery cells and a constant force mechanism (CFM) coupled to a battery cell. The CFM includes a first vertical spring, a second vertical spring, a horizontal spring, and a plurality of rigid links. A centerline-to-centerline distance between the first vertical spring and the second vertical spring is equal to a free length of the horizontal spring. A first spring constant of the first vertical spring and a second spring constant of the second vertical spring are the same, and the first spring constant and the second spring constant are each half a third spring constant of the horizontal spring.",
