Apparatus and method for charging battery cells

Apparatus for charging a battery cell (4), said device comprising current control means (2) for delivering a charging current until a predetermined charging voltage value is reached, a charging status detector (2,6) devised to sense a charging parameter value, and charging control means (1,5) arranged to terminate charging dependent on a predetermined charging criteria related to said charging parameter. The charging criteria is a charge level value, wherein said charging control means comprises a charging control device (1) for establishing a charge measurement value by integrating said measurement of charging current over charging time, and a charging terminator (5) devised to terminate charging dependent on said charge measurement value and said charge level value.
