23 BCM.1 Module
23 BCM.1 Module
The BCM.1 (Battery Control Module) module is part of
the charging technology and controls up to 32 charging
modules CM.1 1.7 A and CM3.4A via the Charge Control
Bus according to the IU1U2 charging characteristic for lead
Batterys. For this purpose, the temperatures of the battery
environment as well as the charge retention voltage and
high charge voltage are measured. In addition, the string
current of up to four battery strings with 108 cells per string
is measured.
The charging voltage is continuously and automatically
readjusted on the basis of the measurement results.
A DC insulation monitoring system reports insulation faults
in the battery circuit and the automatic ISO fault detection
function reports the circuit in which the insulation fault is
located.
ATTENTION!
The CCB bus is not designed as a SELV system. The bus
components must be treated as if mains voltage (240V)
were applied.
The potential-free relays 11/12, 21/22, 31/32 have no insu-
lation according to SELV. This means that the cabling to
the connected systems must at least be single insulated,
in addition the power supply (24V/0.5A) must at least be
single insulated from mains or battery.
