What is the primary purpose of the battery charger in a traction system?

The primary purpose of the battery charger in a traction system is to charge the batteries directly. In traction systems, batteries serve as a critical energy storage component, providing the necessary power for various functions, including traction efforts of the vehicles. The battery charger ensures that these batteries maintain an optimal charge level, allowing for reliability in operations, especially during situations where normal power supply is unavailable, or during regenerative braking when energy is fed back into the battery.

By directly charging the batteries, the charger helps maintain their health and lifespan, ensuring that the traction system operates efficiently and safely. This role is essential for the overall performance and functionality of the system, as a well-charged battery is vital for supporting the traction motors and other auxiliary systems when needed.
