The invention discloses a novel reconfigurable battery topology and a shunting equalization method. The novel reconfigurable battery topology comprises a plurality of battery modules which are connected in sequence; each battery module consists of a battery Bi, a first switch Si1, a second switch Si2, a third switch Pi1 and a fourth switch Pi2, and one battery module Bn is additionally connected with a bypass switch; the switch Si1 is used for battery series connection, the switch Si2 is used for battery bypass, the switch Pi1 and the switch Pi2 are used for battery parallel connection, and series connection, parallel connection, bypass and series-parallel connection functions of the battery module can be completed. When the whole battery pack works in series and discharges, the two battery modules with the lowest state of charge are connected in parallel to reduce the reduction speed of the state of charge, and when the battery pack is charged, the two battery modules with the highest ...
