Batteries

Background

Updated: 17th October 2006

Batteries may not have changed much in appearance over the last 40 years, but technological advances have been made to ensure they keep up with modern demands. Although lead batteries will continue to start cars for many years, the search continues for lighter, cleaner, more efficient replacements.

The power required by electrical components and systems in cars has steadily increased over the last decade, due to the growing number of electrical safety and convenience systems being fitted. So, whilst heating and air-conditioning, on-board communication systems and heated seats can make cars safer, more economical and comfortable, they also increase consumption of electrical energy.

just-auto has discovered that future vehicle electrical systems may feature two batteries: a starter battery and a general purpose battery. According to Bosch, the "high power for starting" and "general purpose electrical supply" functions will be separated. This will make it possible to avoid the voltage drop during the starting process, while ensuring reliable cold starts, even when the charge level of the general purpose battery is low.
