Abstract
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.

Apparatus for charging one or more capacitors from a battery, the apparatus comprising:
- a DC-DC converter coupleable between the battery and the one or more capacitors and arranged to draw a supply current from the battery and to provide a charging current to the one or more capacitors;
- wherein the DC-DC converter is arranged to determine a supply power drawn from the battery and to alter the supply current drawn from the battery dependent upon the determined supply power.
A method for charging one or more capacitors from a battery, the method comprising:
- coupling a DC-DC converter between the battery and the one or more capacitors so as to draw a supply current from the battery and to provide a charging current to the one or more capacitors;
- determining a supply power drawn from the battery;
- and
- altering the supply current drawn from the battery by the DC-DC converter dependent upon the determined supply power.
