trak® air

Traction energy systems with electrolyte circulation for the most effective solution

If you wish to minimise operating costs through reduced energy consumption and increased availability of your battery system, then HOPPECKE trak® air is the ideal solution for you. The high-quality trak® air system comprises a HOPPECKE traction battery with electrolyte circulation and a microprocessor-regulated charger to ensure rapid and gentle charging of the battery.

HOPPECKE trak® air principle

When a battery is charged, concentrated sulphuric acid is formed. In comparison with “normal acid”, concentrated sulphuric acid is heavier, and sinks towards the bottom of the cell, resulting in acid stratification. To cancel out this stratification mixing of the electrolyte is usually achieved through rising gas bubbles. In standard systems, defined overcharging of the electrodes produces this gas. However, this deliberate overcharging means increased energy and water consumption, extended charging times and higher temperatures.

The HOPPECKE trak® air concept avoids these negative consequences.

Air is introduced into the battery right at the main charging stage. The rising air bubbles circulate the electrolyte, thereby preventing stratification of the acid.

In comparison with other mixing methods, mixing of the acid in-blown air gives the greatest efficiency combined with minimal stress on the plate group, and eliminates the need for the otherwise necessary weekly equalising charges.
