Editing Start-stop system (section)

===BMW===
[[BMW]] is including the technology across many of its cars and the [[MINI (BMW)|MINI]] line for 2008 as part of its Efficient Dynamics brand. BMW has been interested in ways to reduce [[Internal combustion engine#Parasitic_loss|parasitic losses]] on engines, so the company took the technology a step further. Instead of using an Integrated Starter Generator (ISG), BMW has used an enhanced starter which is a conventional starter, developed by [[Robert Bosch GmbH]], that can withstand the increased number of engine-starts in a stop-start vehicle.

BMW has developed the system such that the alternator is not activated most of the time. This means that electrical components in the vehicle are normally running on [[battery (electricity)|battery]] power. When the battery needs to be charged or when decelerating or braking, the alternator is activated to recharge the battery ([[regenerative braking]]). Since this battery experiences very different load characteristics than a normal car battery, BMW used an [[absorptive glass mat]] (AGM) type instead.

Due to the use of [[regenerative braking]], some have started calling this type of system a '''micro hybrid''', a step below a [[mild hybrid]] system where the ISG can be used to assist the engine or even drive the vehicle.
