Abstract
The invention relates to a method for balancing a battery pack () comprising a plurality of battery cells () for an electric vehicle. The method comprises: determining the state of charge (SOC) for each of said battery cells (); receiving information related to the expected use of the electric vehicle to a prediction horizon; and determining a state of balance value (SOB) at the current time and an expected state of balance value (SOB) at the end of the prediction horizon. Furthermore, the method comprises balancing the battery cells () based on the state of balance value (SOB) at the current time and the expected state of balance value (SOB) at the end of said prediction horizon, such that the state of balance (SOB) and the use of the cell balancing process is optimized so as to minimize the energy usage of the battery pack (). The invention also relates to an arrangement for balancing a battery pack ().
