Component Overview And Handling Of 48 V Vehicle Electrical System

Information 

Identification 

• The components and cables are marked in accordance with current standards.
• There is no need to use additional identification stickers (as used on hybrid vehicles) for the vehicle in the workshop.
• Hybrid vehicles with or without PDCC are identified by the existing green and red stickers.
• There is no need to disconnect contacts when working on adjacent systems.

Documentation 

• Individual HV components and standalone HV systems without a HV energy store are not documented during the test log.
• If work is interrupted, the condition of disconnected contacts must be checked before starting the tasks again (e.g. disconnected and masked cables).

Qualification 

• Employees with in-depth electrical training and system knowledge.
• Prerequisite in the Porsche dealer organisation: Qualification to the level of HVT and system qualification (e.g. by completing training/WBT) for the 48 V vehicle electrical system.

Disposal 

• The 48 V additional battery is not  exempt from the legal requirements relating to the disposal of solid and liquid waste materials.
• As an undamaged unit, it is not  specifically listed as hazardous waste.
• The 48 V additional battery contains materials that can damage the environment if not disposed of correctly.
• The main material here is the electrolyte, which contains acetonitrile and tetraethylammonium tetrafluoroborate.
• These materials must be disposed of by waste disposal companies  that specialise in industrial waste and do not release components of ultra-capacitors into the environment or dispose of waste in rubbish dumps.
• National laws and regulations and local laws and regulations must be met.

Transport 

• The energy value is approx. 6.75 Wh, i.e. the 48 V additional battery is not subject to any other regulations of the ADR, IMDG code and IATA-DGR, which means that no special packaging is required.
• If the 48 V additional battery has to be transported, always use the original packaging.
