the most common service battery technologies by increasing the
voltage coming from the alternator using a DC-DC converter.
the charge curve related to the service battery technology in
use (wet lead-acid, gel, Agm, lithium), must be selected using
internal jumper switches. The 5 charging phases operate
independently from the input energy source, and for each phase
the voltage and current supplied are continuously monitored,
so as to quickly charge the battery as efficiently as possible.
Charging from the alternator
After the engine has started (and the alternator), the Ignition+

During charging, the voltage of the starter battery will be
constantly monitored to check any problems of supply or
overload by the alternator, intervening promptly, if necessary,
reducing the output current or stopping the charge completely.
the output current is limited if the
active signal d+ (or ignition+) and starter battery voltage below
13V.
the device switches off completely if it detects a voltage of
12.8V at the starter battery, or if the signal d+ or Ignition+ (ie
engine shutdown) is no longer detected.

thresholds of the device are as follows: activation >12V
and deactivation <11.8V. in the latter case, the activation
