Vedlikeholdslading 12VDC Batteri

[quandt1960]

Hei

Er det noen av dere som vedlikeholdslader 12VDC batteriet i bilen? Eller blir det ladet fra bilens drivlinjebatteri?

Buck
mode
is
the
normal
operating
mode
when
the
high-voltage
system
is
active.
The
DC/DC
converter
transfers
electrical
energy
from
the
high-voltage
electrical
system
to
the
12 V
vehicle
electrical
system
and
assumes
the
function
of
the
alternator
in
a
conventional
vehicle.
The
DC/DC
converter
must
reduce
the
varying
voltage
from
the
high-voltage
electrical
system
to
the
voltage
in
the
low-voltage
vehicle
electrical
system.
The
voltage
in
the
high-voltage
electrical
system
is
dependent,
for
example,
on
the
state
of
charge
of
the
high-voltage
battery
(about
260 V
to
about
390 V).
The
voltage
in
the
low-voltage
vehicle
electrical
system
controls
the
DC/DC
converter
so
that
the
12 V
battery
is
optimally
charged
and
sets
a
voltage
of
about
14 V
depending
on
the
state
of
charge
and
the
temperature
of
the
battery.
The
EME
control
unit
communicates
with
the
EDME
control
unit,
in
which
the
12 V
power
management
functions
are
performed.
The
result
is
the
setpoint
value
specification
for
the
voltage,
which
the
DC/DC
converter
should
adjust
in
the
low-voltage
vehicle
electrical
system.
The
continuous
output
power
of
the
DC/DC
converter
is
2500 W.
