Abstract: A battery charger for charging rechargeable batteries and/or battery packs is disclosed. Preferably the charger can apply two modes of charging a battery. In a normal charging mode a battery is charged to full capacity at a low rate. In a boost charging mode the battery is charged very rapidly and preferably only to a certain degree, such as 75% of its maximum capacity. The boost charging mode makes it possible to provide some charge to the battery when the time available for charging is limited. The boost charging method is based on a very high initial charging current (Iinit) The initial current (Iinit) is such that a predetermined maximum charging voltage (Vmax) is reached almost immediately. The charging current is then decreased in such a way that the charging voltage (Vcharge) is maintained substantially constant at the maximum charging voltage (Vmax).

Abstract: The invention relates to an electrochemical energy source comprising at least one fuel cell, which fuel cell comprises: a first current collector coupled to a negative electrode, a fuel source connected to said negative electrode, a second current collector coupled to a positive electrode, an oxidant source connected to said positive electrode, and an ion-conducting electrolyte located between said negative electrode and said positive electrode. The invention also relates to an electronic device incorporating such an electrochemical energy source.
