IEC 63118-1 Ed. 1.0 b:2024

This part of IEC 63118 specifies the general tests and requirements for the performance of lithium secondary batteries with a nominal voltage of 12 V permanently installed in road vehicles not for propulsion. The replacement of secondary batteries permanently installed in road vehicles not for propulsion is covered by this document.

The following are typical applications that utilize the batteries under the scope of this document: power source for the starting of internal combustion engines, lighting, stop and start function, on-board auxiliary equipment and energy absorption for regeneration from braking.

The batteries primarily used for propulsion of electric vehicles (EV) including battery electric vehicles (BEV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles (PHEV) are not covered by this document.

This document includes:
• electrical characteristics tests methods and requirements;
• a life duration tests method.

This document does not include:
• dimensions;
• the system communication protocol;
• safety aspects.

NOTE The safety aspects of the batteries are covered by IEC 63057.
