Abstract
A method and a charging device serve for charging rechargeable lithium accumulators. A charging current is injected into the accumulator, and the voltage is monitored on the accumulator during the injection process. Additionally, the variation in time of at least one state variable characteristic of the accumulator is monitored and injection of the charging current into the accumulator is continued until the variation in time of the state variable exceeds a predefined limit value.
