Method for charging e.g. lead-acid battery, connected at electrical charge source, for e.g. electric car, involves selecting charge pulses for battery charging depending on charging and/or nominal capacity of battery during charging phases

摘要

The method involves utilizing constant charging current in a first charging phase until electrical charging voltage and/or charging voltage change reaches a predetermined reference value. Constant charging voltage is utilized in a second charging phase until electrical charging current and/or charging current change reaches another predetermined reference value. A battery (12) is charged by charge pulses in third charging phase, where the charge pulses are selected depending on charging and/or nominal capacity of the battery during the first and second charging phases.
