Abstract
A battery energy processing device includes: first and second inductors, first and second phase bridge arms, an energy storage element, and a controller. First ends of the first and second inductors are connected with a positive electrode of a battery. A midpoint of the first phase bridge arm is connected with a second end of the first inductor; A midpoint of the second phase bridge arm is connected with a second end of the second inductor. A first end of the energy storage element is connected with a first confluent end; a second end of the energy storage element is connected with a second confluent end. The controller is configured to control the first and second phase bridge arms to charge and discharge the battery through the first and second inductors to heat the battery. The first and second inductors are in different operating states.
