| 摘要 |
The invention relates to a method for heating an electric energy store (1) having a plurality of storage cells (2, 3, 4). Provision is made for the energy store (1) to be connected electrically to a cell equalizing circuit arrangement (11) for removing energy from the storage cells (2, 3, 4), temporarily storing the energy removed in at least one electric storage element (16, 17, 18, 19) and at least partly feeding back the temporarily stored energy into the energy store (1). In order to heat the energy store (1), the energy removal, the temporary storage in the electric storage element (2, 3, 4) and the feedback are carried out depending on the storage temperature of the energy store (4). The invention further relates to a corresponding cell equalizing circuit arrangement (11) and a corresponding electric energy store (1). |
