12 V battery
The 12 V battery supplies the 12 V on-board network independently of the high-
voltage batteries, and is necessary for powering up the system and switching on the
high-voltage batteries.
During normal operation, charging the 12 V battery using an external charger unit is
not necessary. If the high-voltage batteries are switched on during charging or while
in travel mode, then the 12 V battery is recharged at up to 10 A.
For additional loads on board (e.g. position lights, radio), it may be necessary to
connect another battery using an isolation diode. This prevents the DEEP BLUE
system’s 12 V battery from becoming fully discharged, which would prevent the
DEEP BLUE system from being restarted.
If currents greater than 3 A are permanently required for the on-board power sup-
ply, then Torqeedo recommends the installation of an additional 12 V supply. This
prevents the 12 V battery from becoming fully discharged, which would prevent the
DEEP BLUE system from being restarted.
ADVICE
The 12 V battery is responsible for switching on the high-voltage batteries at
every start. Ensure that it is sufficiently charged. The 12 V battery is automatically
recharged during the operation of the DEEP BLUE system.
Circuit breaker
The circuit breaker protects the power circuit from damage which could be caused
by an overload of the wiring.
