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.

High-voltage connections
At the Electrical Machine Electronics, there is a total of three high-voltage
connections to connect the
lines for other high-voltage components. The connections for the electric A/C
compressor and the
electrical heating are on the convenience charging electronics.
