Battery-to-battery charger

The battery charger is connected in parallel with the engine battery (like a relay) and therefore requires no modification of the charging circuit (the alternator is connected directly to the engine battery).

Some models offer voltage conversion, so you can recharge a 24 v battery, such as the bow thruster, from a 12 volt alternator, or recharge a 12 v service battery directly from a 24 v alternator. Also note that battery-to-battery chargers can limit the current, a useful feature to respect the charging constraints of Lithium batteries, or to limit the alternator's power output and protect it from premature wear.

The new models also enable :

Reduce the charging voltage of certain alternators (whose charging voltage exceeds 14v)

An adapted maintenance phase.

Recharging for vehicles equipped with regenerative brakes (Euro 6 standards).
