ABSTRACT:
A device for quick charging of batteries, whereby the charging current of the battery is directed in constant current impulses. Several charging current strengths of varying strengths, are brought into effect, depending on the respective charging condition of the battery, by clock impulses. Assigned to each charging current strength is a battery-specific zone in the electrochemical voltage gradient U=f(t), whereby the individual zones are indicated by voltage set values. The voltage zone assigned to each charging current strength is so chosen that in passing through this zone, no heating or gassing occurs. Thereby use is made of the fact that the battery at the beginning of the charging can accept a very high current. The charging condition of the battery is measured in each impulse pause, stored and compared with the voltage set value. Where there is a variance, the set-current value assigned to the zone is correspondingly adjusted.
