Vehicle electrical system and batteries

Your vehicle has a specialized electrical system that delivers electricity to and from the batteries. There are both high-voltage and low-voltage circuits for different electrical functions.

This section of the manual presents information about several of its electrical components. These include:

The traction battery
12 V battery
The emergency 12 V supply terminal
Fuses

Tip

Vehicle charging

Features and equipment related to charging, such as the charging port and cables, have their own section.

Convenience features

Power-related features, such as USB ports and wireless device charging, are covered in other sections.

Warning

Do not handle or modify the vehicle's electrical components. Only perform actions that are clearly described in the manual.

Traction battery

Your vehicle's traction battery is the central energy and power source for your vehicle. It powers all electric propulsion and indirectly powers the rest of the vehicle by keeping the smaller 12 V battery charged.

12 V battery

The 12 V battery powers everything in your vehicle except the electric propulsion.

The emergency 12 V supply terminal

The emergency 12 V supply terminal can be used by service technicians to access the vehicle if it has discharged batteries and is unresponsive.

Battery recycling

Used batteries must be recycled in an environmentally sound manner.

Fuses

Electrical fuses protect different parts of the electrical system by shutting off power if the current exceeds the fuse's threshold. A blown fuse must be replaced to restore functionality.
