The brake disc (or rotor) is the rotating component of a wheel's disc brake system, where brake pads press against to slow down or stop the vehicle. Typically made from gray iron, it is known for its durability and heat dissipation properties. The design can be solid or ventilated, with ventilated discs being more common in high-performance or heavy-duty applications due to their ability to dissipate heat efficiently. This helps prevent overheating and ensures consistent braking performance even under intense use.

A home electric vehicle charger is a device that provides convenient charging for electric vehicles. We can install and use it at home. Common home chargers include wall-mounted charging stations and portable chargers, such as QINGYUAN's portable charger, which supports a variety of voltage and current specifications and is suitable for electric vehicles compatible with J1772. When we choose a home charger, we need to consider factors such as charging speed, installation space, and connection method.
