Toyota bZ4X Owner's Manual: Power Sources for Charging

To ensure safe and efficient charging, the vehicle requires an external power source that meets specific criteria. Before starting the charging process, always confirm that the power supply is compatible with the vehicle’s electrical requirements.

WARNING: Electrical Faults & Precautions

Charging must be conducted in accordance with the precautions outlined in the Owner’s Manual. Using a power source that does not meet the proper requirements or failing to follow regulations can lead to electrical hazards, posing serious risks such as fire, electric shock, or injury.

Key Considerations for Safe Charging:

• Ensure the voltage and output of the power source align with the vehicle’s specifications.
• Avoid using damaged outlets or extension cords, as they can create safety hazards.
• Do not charge in areas with excessive moisture or unstable power supply conditions.
• If an electrical fault occurs, immediately disconnect the charging cable and inspect the system before resuming use.

Following these precautions helps maintain a stable and secure charging process, preserving both battery health and vehicle safety.

Power sources

• Connect to an AC 120 V outlet (NEMA 5-15R) with a Ground-Fault Circuit-Interrupter (GFCI) and a circuit breaker. Use of a 15A individual circuit is strongly recommended to ensure AC charging cable will operate properly.
• When charging outdoors, make sure to connect to a weatherproof outlet that is certified for outdoor use.

  Checking Ground-Fault Circuit- Interrupter (GFCI) operation before its use is recommended.

Recommended Charging Environment for Electric Vehicles

For safe and efficient charging, the following equipment and settings are highly recommended. Adhering to these guidelines helps prevent electrical hazards, ensuring a reliable charging experience for your vehicle.

Weatherproof Outlet

When charging outdoors, always use a weatherproof outlet designed to withstand environmental conditions. Ensure the plug remains properly sealed during charging to prevent water exposure, which could compromise safety and charging efficiency.

Dedicated Circuit for Safe Charging

• To reduce fire risks, connect the charger only to a dedicated 15A branch circuit equipped with over-current protection, following the National Electric Code (ANSI/NFPA 70) regulations.
• To prevent electric shocks, use an outlet featuring a Ground-Fault Circuit-Interrupter (GFCI) or an Earth Leakage Circuit Breaker to ensure added protection when handling the plug.

By ensuring the correct charging environment, users can maximize safety while preserving the integrity of the vehicle's battery system.

Power Source Precautions

To prevent electrical hazards, fire risks, or serious injury, it is essential to use a properly regulated power source when charging your vehicle. Following these safety guidelines ensures a stable and secure charging process.

Key Safety Guidelines:

• Always connect to an AC 120V outlet (NEMA 5-15R) with a Ground-Fault Circuit-Interrupter (GFCI) and a circuit breaker, as required by local electrical codes.
• A dedicated 15A circuit is strongly recommended to reduce the risk of electrical overload and ensure consistent charging performance.
• Never use power strips, multiple outlet adapters, or conversion plugs, as they may lead to overheating, electrical faults, or system failures.

By adhering to these precautions, users can maintain a safe and efficient charging routine while protecting both their vehicle's battery system and electrical infrastructure.

• Connecting the AC charging cable to an extension cord is strictly prohibited. The extension cord may overheat and does not contain a Ground- Fault Circuit-Interrupter (GFCI).

  The leakage detection function of the CCID (Charging Circuit Interrupting Device)  may not operate correctly.

WARNING

Do not connect to a branch electrical outlet.

For safe charging, avoid using a block heater and always connect the charging connector directly to the AC charging inlet-do not insert any converting adapter or extension cord between them, as this may compromise system integrity and performance.
