Dan zou je dat intelligente systeem natuurlijk kunnen controleren of die dan ook laad met 14.6v max 14.8v

Dat zou (indirect) kunnen, al light het iets complexer..... Het laadsysteem kijkt naar het gedrag/ladingstoestand van de accu

IBS – Operation :
The IBS performs the following measurements:
Battery voltage. (V)
Battery current. (A)
Battery temperature (°C/F)

The BCM processes these values and calculates the following parameters which express the status of the
battery:

State Of Charge (SOC): The SOC indicates residual battery charge percentage compared to its rated capacity. This is the amount of charge in the battery .
State Of Health (SOH): The SOH indicates the real battery capacity percentage compared to its rated capacity .
As the battery ages over time, its ability to be fully recharged and to supply energy is reduced.
State Of Function (SOF): The SOF indicates the minimum voltage peak which can be reached during cranking (V) .

These parameters identify the startup capacity of the battery . The battery may no longer be able to restart the
engine if the SOC or SOH is compromised.

In case of insufficient SOF, the battery voltage during cranking may reach such low values that the standard
operating conditions of the vehicles electrical systems are no longer guaranteed to properly perform.

Al is het inmiddels ook duidelijk dat bijna iedereen (vooral ook in USA) overgaat van EFB naar AGM, waarna zo goed als alle problemen over zijn .... ;)
Ook Varta zelf geeft aan dat EFB zondermeer vervangen kan worden door AGM, en zelfs aangeraden is bij auto's met veel verbruikers

When is a change from EFB to AGM recommended?
An upgrade to an AGM battery is always advisable if a large number of electrical consumers cause an increased power demand or if maximum availability for use is required. One advantage of AGM batteries is the fuel saving which is achieved with the effective operation of the automatic start-stop system – and therefore saving money. All consumers in the onboard network benefit from a good power supply, even during stop phases and also operate reliably under unfavorable weather conditions.

Mbt intelligent laadsysteem:
Een bevriende garagehouder vertelde dat tegenwoordig de dynamo vooral werkt op het moment dat je afremt.
Vroeger vooral als de motor toeren maakte, maar ivm emissieeisen wordt dan tegenwoordig de dynamo min of meer uitgeschakeld.

klopt, is bij de giulia/stelvio ook zo ;)
