1.4. Description of the
centralized filling system
1.4.1. General description
This chapter describes the
working principle of the single
point water filling system used
on STM monoblocks.
!
Assembly instructions
see chapter 3.3.
!
Operating instructions
(topping-up)
see chapter 6.2.
The water filling system connects
a number of monoblocks in
hydraulic series.
During normal operation of
the battery, a significant amount
of the gases produced during
overcharge recombines in the
batteries. The remaining gas is
exhausted through the hydraulic
system.
When topping-up of the battery
is necessary, water filling is done
from a reservoir that feeds the
battery with a low-pressure pump
or through gravity. The topping-up
is being effected cell by cell to a
predetermined level. The filling of
an hydraulic system is completed
when all batteries are filled and
water appears at the end of its
hydraulic system. The filling of a
battery is completed when all
cells of the battery are filled.
The main component of the
system is the water filling ramp
that guarantees the evacuation of
the gases, as well as the
automatic regulation of the
electrolyte level in each cell
during topping-up.
For a battery with several
hydraulic circuits, the topping-up
will be done separately for each
hydraulic circuit.
