| 摘要 | Under one aspect, a heating circuit for a battery includes a plurality of switch units, a switching control module, a damping component, an energy storage circuit, and a polarity inversion unit. The energy storage circuit is connected with the battery, and includes a current storage component and a plurality of charge storage components that respectively are connected with the plurality of switch units in series to form a plurality of branches that are connected in parallel with each other and in series with the current storage and damping components. The switching control module controls switching on and off of the switch units, so that energy flows back-and-forth between the battery and the energy storage circuit when the switch units switch on. The polarity inversion unit is connected with the energy storage circuit inverts a voltage polarity of the plurality of charge storage components after the switch units switch off. | ||
