Abstract
A rechargeable battery pack which includes several battery cells. Each cell has a positive electrode and a negative electrode connected in series. Each of the battery cells further includes a reverse polarity protection device. The protection device includes a low voltage switch connected between the positive electrode and the negative electrode of the battery cell. The low voltage switch is switched on to become a short circuit when a voltage difference between the positive electrode and the negative electrode for each of the battery cells is lower than a threshold switch-on voltage such that the each of the battery cells is bypassed and protected by conducting a current through the short circuit in the low voltage switch.
