Johnson Controls Boosts Fuel-Saving Tech Capacity

One of the ways that automakers are improving fuel efficiency is by getting every Btu out of the fuel, which leads to things like direct gas injection and modified cycles (e.g., Atkinson). But there is another way to increase the performance and efficiency of an engine, at least on an overall basis, and that is to shut it off when it isn’t being used.

But there is another way to increase the performance and efficiency of an engine, at least on an overall basis, and that is to shut it off when it isn’t being used. Assuming that the purpose of an engine is to propel a vehicle, why use the engine when there isn’t any propulsion involved? Just shut it off until you need it.

Which has led to the development of start/stop systems. Shutting off the engine can result in a 5 percent fuel savings.

With all of the starting and stopping that can occur in one’s daily commute to work, this means that the battery is going to be a considerable workout, a workout that will soon exhaust “normal” lead-acid automotive batteries, especially when you take into account the fact that there is a plethora of electronics inside a car or truck. Each one of those motors and screens and seat heaters is looking for its piece of the electricity (were electricity capable of being sliced up like pie).

The alternative approach is to use what’s known as an “absorbent glass mat” (AGM) battery, as it is designed to deal, day in, day out, with the loads, combining power and longevity.

Johnson Controls Power Solutions is the largest automotive battery producer in the world. Some 146-million are produced every year. (Yes, given that number know that they provide aftermarket batteries as well as OEM units.)

According to the company, it anticipates that nearly 50 percent of all cars built in North America will feature stop-start systems by 2020. . .so the company is investing $245-million between now and then to double its AGM production capacity in North America.

It is investing an additional $535-million elsewhere in the world during the same period to increase its global AGM capacity.

At some 5 percent per vehicle, that’s a lot of fuel saved.
