Abstract
An apparatus for managing power in an electric vehicle includes a control circuit and a first switch. The control circuit is configured to generate a first control signal based on a current of a battery operable for powering the electric vehicle, and to generate a second control signal based on a voltage of the battery. The first switch is configured to control connection of the battery to a power source and a load in the electric vehicle according to the first control signal. The first control signal controls a voltage at a terminal of the first switch to maintain the current of the battery to be substantially equal to a current setting, and the second control signal controls the battery to switch between a first state and a second state.
