Conductive charging

The conductive power supply, often a charging base or pad, detects when a compatible receiver or pickup is placed on it.

Contact-based accessories may include changeable backs for cellular phones, special sleeves, or attachable clips.

The charging bases are designed to identify a compatible receiver and only power up when it's detected to avoid risk of electrocution.

[11] Following standards, encompassing "full interoperability" and a "unified and interoperable solution" for ground-level power supply, are scheduled to be published by the end 2024, detailing complete "specifications for communication and power supply through conductive rails embedded in the road".
