The aftermarket for starter motors and alternators has entered a transitional phase as the first wave of vehicles with start stop technology is more than 10 years old and their owners require more cost efficient replacement components than a brand new component from the main dealer.
Leading aftermarket product manufacturers have reacted with a range of stop start starter motors for the most popular vehicles on the road.
The use of these first generation stop start units is limited by the need to maintain power levels for an array of technology and convenience features in modern cars. The power demands of modern accessories have led to calls for a switch to 48-volt electrical systems, which provide more electrical capacity but avoid the costly high-voltage batteries and power electronics of old-style mild hybrids.
New 48-volt mild-hybrid systems can increase the fuel efficiency of internal combustion engines, without the cost and complexity of full-hybrid powertrains.
