Improvements in or relating to a battery charger

摘要

A dual power battery charger for charging a rechargeable battery having power input terminals. The battery charger comprising: (a) a battery charger shell; (b) a first set of input terminals pivotably attached to the shell for electrical connection to a direct current power source at a first voltage; (c) a second set of input terminals for electrical connection to an alternating current power source at a second voltage; (d) a set of output terminals for electrical connection to the power input terminals of the rechargeable battery; (e) a first converter circuit electrically connected between the first set of input terminals and the output terminals of the battery charger for converting a direct current at the first voltage to a direct current at a third voltage suitable for charging the battery; and (f) a second converter circuit electrically connected between the second set of input terminals and the first set of input terminals of the battery charger for converting an alternating current at the second voltage to a direct current at the first voltage.
