Abstract
A battery module including a first positive terminal, a second positive terminal, a ground terminal, a power conversion circuit, and a power assembly. The power assembly includes a plurality of battery cells coupled in series and disposed in a stacked orientation relative to each other and configured to output a first voltage between the first positive terminal and the ground terminal. The power conversion circuit is electrically coupled to the power assembly and configured to receive the first voltage as an input and to output a second voltage different from the first voltage. The second positive terminal is electrically coupled to the power conversion circuit to receive the second voltage from the power conversion circuit.
