1. A method performed by battery charger configured to charge a vehicle battery, the method comprising:
initiating, at a first point in time (t_Bulk_Start), charging of the battery in a bulk charging mode,
determining, at a second point in time (t_Bulk_End) subsequent to the first point in time (t_Bulk_Start), that the charging of the battery in the bulk charging mode is completed,
estimating, at the second point in time (t_Bulk_End), a state of charge of the battery at the first point in time (t_Bulk_Start) when the charging of the battery in a bulk charging mode was initiated,
initiating charging of the battery in a subsequent charging mode using the estimated state of charge (SoC_Bulk_Start), wherein the subsequent charging mode is selected from an absorption charging mode and a float charging mode.
