Abstract

A charging and heating apparatus includes a power unit configured to be connected to a battery to be charged/discharged and perform voltage conversion on a received voltage and current and output a converted voltage to the battery, a unidirectional/bidirectional conversion unit connected to the power unit and configured to output a bidirectional alternating current or a preset current to the power unit, and a control unit connected to the unidirectional/bidirectional conversion unit and configured to, in response to the battery being in a heating mode, control the unidirectional/bidirectional conversion unit to output the bidirectional alternating current to the corresponding power unit, such that the battery self-heats under excitation of the bidirectional alternating current, and in response to the battery being in a charge/discharge mode, control the unidirectional/bidirectional conversion unit to output the preset current to the power unit, such that the battery is charged/discharged.
