System and Method for Charging of a Rechargeable Battery
First Claim
1. A method of charging a battery, which method comprises:
- supplying an essentially constant charging current of a predetermined first magnitude from a power source to the battery, during a first constant current mode of charging;
switching to a second constant current mode of charging when a battery voltage reaches a predetermined threshold value; and
supplying an essentially constant charging current of a predetermined second magnitude to the battery, during the second constant current mode of charging, wherein the second magnitude is lower than the first magnitude.

Abstract
A method of charging a battery (50). The method comprises the step of supplying (101) an essentially constant charging current (C) of a predetermined first magnitude (C1) from a power source (10) to the battery (50), during a first constant current mode (CC1) of charging. Furthermore the method comprises the step of switching (102) to a second constant current mode (CC2) of charging when a battery voltage (Vb) reaches a predetermined threshold value (Vt1); and the step of supplying (103) an essentially constant charging current (C) of a predetermined second magnitude (C2) to the battery (B), during the second constant current mode (CC2) of charging. The second magnitude (C2) is lower than the first magnitude (C1).
