Electronic diode splitter

Electronic diode splitter to charge several battery groups. Case no current flows through the alternator, the mutual influence between batteries will be prevented. The electronic diode splitter is an improvement of the conventional battery isolator with a very low voltage drop MOS-FET-Technology during the charge operation. All disadvantages of voltage drop (0.7-1.0 V) and consequently power lost are eliminated and the batteries will be charged with maximal acceptable current.



Charging multiple battery systems


Problem:

To charge two or more independent battery systems with an altenator, there must be a battery isolator or an electronic diode splitter present. The batteries are electronically split so that they don't discharge one another The batteries on board a vessel need an adequatly high charge voltage of about 14 V minimum for a sensible charge. Conventional battery isolators create a voltage drop of 0.7 V to 1.0 V causing the batteries to be charged with only 13 V. This results in the battery being only half full and a lower current difference, between battery isolator and battery, that will cause a lower charge current as well. The electronic diode splitter is the next step from the conventional battery isolator. Its electronic recognizes charge status and overrides the diodes.

Solution:

For a better charge performance through the altenator, we recommend a voltage drop free battery isolator. Another possibility is to exchange the original regulator that raises the output voltage of the alternator to compensate voltage drop of the isolator. This concept only works with a few types of alternator and there is almost always tampering with the altenator involved.

An active charging relay is used if you don`t want or cannot change the wiring to the alternator and you want to add a second battery group which has to be charged while the engine is running. The active charging relay detects if the alternator is running and the voltage rises and then it connects both battery groups together automatically. If the voltage drops under a certain threshold the batteries are separated automatically in order to prevent an unintentional discharging of the starter battery. Automatical metering and setup to 12 V- or 24 V operation mode.

  •  for battery groups > 200 Ah, emergency start function by remote button

  •  also useful as active load relay to activate certain loads only while the
     alternator is running.
