Battery operation
Backup batteries for rolling stock of the type ZeMaXXPxx may only be discharged down
to the specified
discharge voltage
U
final
. For the values of your system refer to the
„System specific Technical Data“ (see Position "
U
final
").
After a discharge
recharge the battery system immediately
in
accordance with the regulations described in section before.
Implicitly
avoid longer holding times without full charge
,
this will prevent damaging your system.
In
the event of an interruption
(e.g. equipment failure) a discharge to 1.65 Vpc is
allowed. Thereafter the battery has immediately to be fully recharged and the total
voltage has to be checked. In case of repeated failing, we recommend to maintain in the
workshop a preventive full charge of the battery according to 8.6.2 “Equalization charge”.
Risk of explosion !
During all operating conditions
hydrogen can escape
from the cells
valves.
Venting spaces and cabinets in which batteries are operated
sufficiently well
Avoid the risk of explosion by strictly following the ventilation rules of EN 62485-2 : 2019
"
Safety requirements for secondary batteries and battery installations
"
When the train is set out of service a discharge (by consumer loads) must be avoided.
Keep the batteries either on float charging or process them in accordance with chapter 9
Decommissioning in the vehicle

Service
The 2V ZeMa
Rail
single cells for rolling stock batteries are designed with sealed
maintenance-free cells (VRLA) filled with AGM fixed electrolyte. No water must be refilled
into these cells.
Attention!
It is prohibited to open the cell housing to fill in water or other
substances.
For a long lasting hassle-free operation it is important that the charging technology is
correctly parametered to the operating conditions. Make yourself familiar with the
