When a traction battery is fully discharged and no longer has enough energy to power an electric vehicle, there are several options for managing the battery.

1. Charging: In many cases, a discharged traction battery can be recharged. This can be done by connecting the vehicle to a charging station or a power outlet. Charging the battery may vary in time, depending on the charging speed and the battery's capacity. It's important to follow the manufacturer's recommendations regarding battery charging.

2. Maintenance charging: If the battery is not used for an extended period and is completely discharged, it can be harmful to the battery's performance. In that case, it may be advisable to perform a maintenance charge. This involves periodically charging the battery to maintain its capacity and lifespan. Refer to the manufacturer's guidelines for proper maintenance charging procedures.

3. Replacement: If the battery no longer has sufficient capacity or can no longer be efficiently charged, replacement may be necessary. Traction batteries have a limited lifespan, and over time their capacity can decrease. In such cases, it may be necessary to replace the battery with a new one with the correct specifications for the vehicle.

4. Recycling: When a traction battery has reached the end of its life and can no longer be reused or repaired, it must be recycled responsibly. Traction batteries contain valuable materials, but also potentially hazardous substances. It is important to follow local regulations and deliver the battery to a recognized recycling company or a battery collection point.

Proper management of discharged traction batteries is essential to ensure safety, protect the environment, and reuse valuable resources. It is advisable to contact a professional battery supplier or a recognized recycling company for specific guidelines and advice regarding traction battery management.
