BMW 3: Labels
Three signs are attached to the housing of the high-voltage battery unit: 1
type plate and 2 warning
stickers. The type plate provides logistical information (e.g. part number) and
the key technical data
(e.g. nominal voltage). The warning stickers point to the lithium-ion technology
on the one hand, and
on the other to the high electrical voltage that exists in the high-voltage
battery unit. They thus raise
awareness of the potential dangers involved.
The type plate is now also legible with the high-voltage battery installed.
