Function and structure

5.1.

Battery

Batteries are interconnected from rail.power blocks/cells and used in rail vehicles.

Here they perform one or more of the following functions:

•

Buffering and supply of the low-voltage vehicle electrical system

•

Provision of energy in emergencies

•

Provision of energy for the maintenance and upgrading of vehicles

•

Start of the vehicle drive motors

5.2.

rail.power blocks/cells

HOPPECKE rail.power batteries are valve-regulated lead-acid batteries (VRLA) and are
specially designed for use in rail vehicles. rail.power batteries are available as single cells
(2V) as well as block batteries (6 V, 12 V).

The following figure shows an example of the structure of a HOPPECKE rail.power block:

A block consists of 3 (6 V block) or 6 (12 V block) cells. They are installed in a single
housing. The individual cells consist of grid structure electrodes. Each positive electrode is
wrapped in a fleece. The electrolyte is fixed in this fleece.

Each cell has valves. These open at a certain pressure and allow any gases that may occur
to escape in the event of overcharging.
