1 Scope
This part of IEC 60095
is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily
as power source for the starting of internal combustion engines (ICE), lighting and
also for auxiliary equipment of ICE vehicles. These batteries are commonly called
“starter batteries”.
The batteries within the scope of this document are used for micro-cycle applications
in vehicles which can also be called start-stop (or stop-start, idling-stop system,
micro-hybrid or idle-stop-and-go) applications. In cars with this special capability, the internal combustion engine is switched off
during a complete vehicle stop, during idling with low speed or during idling where
there is no need to support the vehicle movement by the internal combustion engine.
During the phases in which the engine is switched off, most of the electric and electronic
components of the car are supplied by the battery without support of the alternator.
In addition, in most cases an additional regenerative braking (recuperation or regeneration
of braking energy) function is installed. The batteries under these applications are
stressed in a completely different way compared to classical starter batteries. Aside
from these additional properties, these batteries need to crank the ICE and support
the lighting and also auxiliary functions in a standard operating mode with the support
of the alternator when the internal combustion engine is switched on. All batteries
within this scope fulfil basic functions, which are tested under the application of
IEC 60095‑1.
