The Advantage

The Customized 3-in-1 Automotive OCV Levelling Machine is designed for pre-check of open circuit voltage and checking of under- and over-filling of
sulphuric automotive batteries. The individual batteries supplied through the conveyor of the finishing line
are exactly positioned. The fill stroke moves down, and the levelling heads are lowered into the filling
holes of the battery. The first station checks the acid level in the battery. If a battery is under-filled it will
be topped-up to the level, if a battery is over-filled it removes the acid out of the battery with diaphragm
pumps. As a result, the acid level is accurate in all the individual cells by means of hose sensor
monitoring. The second station will check the levelling unit by lowering the Check heads with a distance
measuring system until each tungsten electrode gets in contact with acid. The result will be displayed on
the HMI for verification. An exact level achievement is guaranteed. If a battery fails it will be rejected on a
reject table.
