Apparatus and Method for Charging an Accumulator
First Claim
1. Apparatus for charging an accumulator of electrical charge, comprisingan apparatus for supplying electrical current from externally supplied energy and for supplying current at an output voltage differential, andterminals for supplying charging current to an accumulator to be charged at an imposed voltage differential, wherein:
- the apparatus is provided with a second accumulator of electrical charge, comprising at least one electrochemical cell, which is connected in series to the apparatus for supplying electrical current between the terminals, such that a voltage differential across the series-connection is larger than the output voltage differential of the current-supplying apparatus.

Abstract
An apparatus for charging an accumulator (1) of electrical charge comprises an apparatus for supplying electrical current from externally supplied energy and for supplying current at an output voltage differential, and terminals for supplying charging current to an accumulator (1) to be charged at an imposed voltage differential. The apparatus is provided with a second accumulator (9) of electrical charge, comprising at least one electrochemical cell, which is connected in series to the apparatus (6) for supplying electrical current between the terminals (2, 3) r such that a voltage differential across the series—connect ion is larger than the output voltage differential of the current—supplying apparatus.
