A battery heating system (10) and an electric vehicle (1000). The system (10) comprises: a power battery pack comprising a first battery pack (1) and a second battery pack (2) connected in series, a center line being led out at a series connection point (A) of the first battery pack (1) and the second battery pack (2); n buck-boost inverters (3), each comprising an inverter bridge and an inductor, wherein the n inverter bridges are connected in parallel to form a first bus terminal (B) and a second bus terminal (C) the first bus terminal (B) and the second bus terminal (C) are correspondingly connected to positive and negative electrodes of the power battery pack, one end of the inductor is connected to a midpoint of the corresponding inverter bridge, and the other end of the inductor is connected to the center line, n being an integer greater than 1; and a controller (100) connected to the control end of the inverter bridge, and configured to perform out-of-phase control on the n buck-boost inverters (3), so as to realize simultaneous self-heating of the first battery pack (1) and the second battery pack (2).
