Recombination system for stationary batteries.

Technical description :

In the operation of storage batteries with aqueous electrolyte, not only is electrical energy stored during charging or charge conservation, but water decomposition also takes place as a secondary reaction.

This produces gases hydrogen and oxygen which can escape from the battery, resulting over the course of time in a drop in the level of the electrolyte and an increase in its concentration. The rate at which the electrolyte level falls depends on operating environmental conditions, e. g. temperature and on the charging parameters. Consequently, battery installation, require regular checking and topping up of the electrolyte with suitable water.
The instructions for use of the batteries concerned must be observed.

The mixture of hydrogen and oxygen gas produced during operation of the battery is called detonating gas. This designation is derived from the fact that hydrogen forms an explosive mixture with air in concentrations of 4% and above. In order to avoid such critical concentrations, specific level of ventilation of battery rooms and cubicles is prescribed (see DIN VDE 0510 part2).
The ventilation requirements may then be reduced if there are technical measures which lessen the formation of hydrogen or its escape from the battery.

In order to reduce the escape of this gas, hydrogen and oxygen may be converted back into water in a so called recombination system. This reaction takes place in the recombinators, which are special plugs mounted on the cells.
