How are the batteries charged in the aircraft?

Batteries in the aircraft are charged automatically when direct current (DC) power is supplied to the DC BAT bus and the battery switches are in the ON position. This is a designed feature that ensures the batteries receive the necessary power to charge while the aircraft is operating in a normal configuration. When the battery switches are activated, it allows the charging system to function effectively, powering the necessary systems and ensuring that the batteries are kept in a state of readiness for when they are needed.

In normal operations, when the battery switches are ON and DC power is available, the charging process happens seamlessly, which helps maintain the power supply for critical systems onboard even if the engines are not running or if there are other power issues. The system is designed with safety and reliability in mind, ensuring that the aircraft can utilize battery power as needed without manual intervention for charging under standard operational conditions.
