A charge storage system 14 of a vehicle comprises a low-voltage battery 22 and a high-voltage battery 18 and is operable in a charging mode in which charge is transferred from the low-voltage battery to the high-voltage battery. A control system 32 comprises one or more processors collectively configured to receive signals indicative of a state of charge of the low-voltage battery, determine whether the indicated state of charge of the low-voltage battery exceeds a first threshold value, and output one or more control signals configured to activate the charging mode for the charge storage system if the indicated state of charge of the low-voltage battery exceeds the first threshold value. The vehicle may comprise a photovoltaic system 12 to supply charge to the low-voltage battery. The control system may deactivate the charging mode when the indicated state of charge of the low-voltage battery drops below a second threshold value that is lower than the first threshold value. The control system may receive signals indicative of a state of charge of the high-voltage battery, and to activate the charging mode only if the indicated state of charge of the high-voltage is below a third threshold value.
