An apparatus for charging one or more capacitors from a battery (18) comprising a DC-DC converter (130) coupleable between the battery (18) and the one or more capacitors (122). The apparatus is arranged to draw a supply current from the battery (18) and supply a charging current to the one or more capacitors (122). The DC-DC converter (130) determines a supply power drawn from the battery (18) and alters the supply current drawn from the battery (18) dependent upon the determined supply power. A corresponding method is also disclosed.
