Toyota bZ4X Owner's Manual: How to Use DC Charging

This section explains the DC charging procedure for the traction battery.

Before starting a DC charging session, always review the DC charger’s operational guidelines to ensure that every step is performed safely and accurately. Adhering to this process is critical for both the efficiency and longevity of the battery.

WARNING

When using a DC charger, it is essential to follow these precautions. Failing to do so may result in an unexpected accident, which can cause severe injury or even death.

• Use only a DC charger that is SAE J1772 compliant to meet all safety and industry standards.
• Avoid using a charging cable that exceeds 30 meters in length to prevent voltage drops and other electrical risks.

Confirm the Following Before Charging

Before initiating DC charging, ensure that all connections and components are in proper working order. Verify that the charger is correctly connected to the traction battery and that there is no damage or contamination on the cables or connectors. This careful pre-charge inspection minimizes the risk of malfunctions and guarantees a smooth, efficient charging process.

Modern electric vehicle charging systems incorporate advanced safety features and smart energy management protocols. For instance, the charging system in the Toyota bZ4X is engineered to deliver rapid DC charging while maintaining optimal battery health, setting a benchmark for safe, reliable performance.

When charging

1. Open the charging port lid.
2. The charging inlet light will illuminate.

3. Open the AC charging inlet cap, and then open the DC charging inlet cap.

4. Insert DC charging connector firmly and fully into the charging inlet.

The DC charging connector shape and treatment will differ depending on the type of DC charger. Perform the operations in accordance to handling procedures of the DC charger.

5. Operate the DC charger and start the charging.

Follow the handling procedures of the DC charger to start charging.

Charging starts after a system check is done.

Stop the charging in accordance to the handling procedures of the DC charger when it is desired to interrupt the DC charging.

• When the DC charging connector cannot be inserted into the DC charging inlet
• If a message indicating vehicle error on the DC charger side is displayed

Even if a message indicating vehicle error on the DC charger side (ex.

vehicle error found, vehicle error occurred, etc.) is displayed, there is no vehicle fault but possibly a communication error between the DC charger and vehicle. In this case, there may be terminal damage (bad contact) in the DC charging connector.

If there is no error with the vehicle, contact the facility manager of the DC charger.
