Requirements to automotive batteries are changing due to increasing electrical content – for example, multiple transient high-power loads that enable various levels of autonomous driving – as well as due to fuel economy and CO 2 emissions targets that drive the broad introduction of micro-hybrid technology. The cascaded process of requirements development, from vehicle functions to power-supply and powertrain system requirements and then down to storage system requirements, is illustrated. Low-volt power-supply system topologies are discussed briefly. Upcoming storage system requirements are outlined, with emphasis on shallow cycle-life at partial state-of-charge (PSoC), as well as dynamic charge-acceptance (DCA). The position of lead–acid technology for automotive applications is discussed in the light of these new requirements, but also in contrast to fast-evolving alternative storage technologies. |
