Hi Fox, I’ve seen this document before and there is some good info in it, but did you see the dates at the bottom of the page.
Not only has lots charged since that was written but ironically, some of the suggested improvements have been adopted.
For instance, Land Rover Discovery 3s have continually adjusting alternator voltages that vary from 13.2 to 15.5 volts, all controlled from the vehicle’s charge management system.
Other vehicles are following suit but the criteria for the charging system in the discovery 4 goes even further with the system able to recognise when the vehicle is cruising or coast down hill, at which point the alternator’s output is optimised to improve the charging of the cranking battery at a time when there is minimal power needed for the vehicle, thus improving fuel economy and reducing exhaust emissions.
