Rheidon - Seasonal Charging Reminder

Common Causes of Socket Overheating

• Loose or aged sockets: Poor contact can lead to high resistance and localized heat buildup.
• Uncertified or outdated wiring: Undersized wires may not meet the current-carrying demands of EV charging.
• Improper installations: Sockets not designed for sustained high loads, or those using extension cables or power strips, may overheat more easily.
• Hot ambient conditions: Charging under direct sunlight or in poorly ventilated areas can amplify the issue.

Summer Charging Best Practices

• Use certified and properly rated sockets (e.g., 16A/230V Schuko with CE/EN certification).
• Avoid aging or loose outlets, and check for signs of wear such as discoloration or loose contact.
• Ensure proper ventilation around the socket and charger.
• Avoid charging under direct sunlight or in enclosed areas without airflow.
• If unsure of socket condition, lower the charging current to reduce stress on the system.

By following these precautions, Rheidon users can maintain a safer and more stable charging experience throughout the summer season.

Smart Temperature Protection: What the HI Warning Means

Rheidon chargers are equipped with advanced real-time temperature monitoring. During hot summer days or when a socket begins to show signs of stress, the system may display an HI warning—indicating that the plug temperature has reached a safety threshold.

When this occurs, charging power is temporarily paused to prevent overheating. This intelligent safeguard helps protect the socket, charger, and vehicle while ensuring a safer charging environment at home.

The HI function is part of Rheidon's commitment to delivering not just performance, but long-term safety and reliability—especially when it matters most.
