Component Overview And Handling Of 48 V Vehicle Electrical System

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 Porsche Panamera, 2022 Porsche Panamera, 2021 Porsche Panamera, 2020 Porsche Panamera, and 2019 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.

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 organization: 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.
