Alternator smart regulators

[Bitsyncmaster]

Found and interesting article on why alternators are using smart regulators.

This is more information than most owners want to read but for those curious.

This is a function I test on new model Nissans. It's a pretty neat feature. Nissan does it a little different then GM and Chrysler, but the idea is the same. It's kinda funny for how complex the system really is compared to the fuel efficiency improvements (typically 2-3% improvement). You also may see newer vehicles with this feature using more advanced batteries to support the Alternator Voltage control, for example the JCI Enhanced Flooded Battery (http://www.johnsoncontrols.com/content/us/en/products/power-solutions/products/lead-acid/enhanced-flooded.html).

The Alternator is not something you would typically think about having new technology improving it when you hear about autonomous vehicles, advanced driving aids, telematics, etc., but there is surprisingly a lot to Alternator/Battery systems in new vehicles today.

It is going to get a LOT more complicated as we see more new battery technologies and different charging strategies. We are also going to see different voltages. We may also see, soon, where the car becomes the standby/emergency power for the house while it is connected up to the charging station.

12V Batteries and High Voltage battery packs for EV/HEVs are completely different. The 12V system will have new stuff to it, such as more aggressive and dynamic charging patterns, but it'll essentially stay between 12-14.5 Volts regulator on Alternator.

For high voltage batteries, Nissan has already demonstrated with a Charger that used a Leaf for back up power. I think they even had a few tied together to run a small medical building or something for total of 8hrs or something.

There are also proposed systems I've seem demoed from suppliers showing power systems between 30-60 volts that utilized more into start/stop systems on conventional ICEs. But that's going way beyond the topic of Software controlled Alternator output. lol
