The “CHARGER ASSY” is a fully assembled charging component assembly used to supply power to the battery pack of a cordless vacuum cleaner. This assembly usually includes a charging adapter, wires, charging circuit, electrical contacts, protective cover and charging cradle. This is an important part that helps ensure the charging process is safe, stable and effective.

Providing a stable power source

The CHARGER ASSY is responsible for converting alternating current (AC) from the socket into direct current (DC) with a voltage suitable for each type of battery, usually 21.6V, 25.2V or 28.8V depending on the model. The charger assembly is designed to ensure a stable and safe current, while preventing overcurrent, overheating or short circuit during charging.

Charging and power management

The charging control circuit (charging control circuit) is integrated inside the CHARGER ASSY, which monitors important parameters such as voltage, charging current and battery temperature. This circuit automatically stops charging when the battery is full, protecting the battery from overcharging or reverse discharge, helping to prolong its life and ensure the safety of the electrical system.

Mechanical and electrical connection

The CHARGER ASSY is designed with an electrical contact head or magnetic charging port (magnetic pin), allowing quick and accurate connection to the battery assembly or the body. This structure makes it easy for users to operate, reducing the risk of contact deviation or damage during charging.

Integrated charging dock and hanging function

Many ASSY CHARGER models are integrated with a charging dock (docking station), allowing users to neatly place the vacuum cleaner upright when not in use, and automatically charge it when attached to the dock. This charging unit provides precise DC voltage to the Battery Pack, maintaining a stable power source during the charging - disconnecting - maintaining process, and combines with the BMS (Battery Management System) circuit in the battery to optimize performance, ensuring longevity and overall electrical safety.
