When a traction battery is completely 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. The time it takes to charge the battery can vary depending on the charging speed and the capacity of the battery. It is important to follow the manufacturer's recommendations regarding battery charging.

2. Maintenance Charging: If the battery has not been used for an extended period and is completely discharged, this can be harmful to the battery's performance. In such cases, 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 cannot be efficiently charged, replacement may be necessary. Traction batteries have a limited lifespan, and over time, their capacity can decrease. In that case, it may be necessary to replace the battery with a new one that has the appropriate specifications for the vehicle.

4. Recycling: When a traction battery reaches the end of its life and can no longer be reused or repaired, it must be responsibly recycled. Traction batteries contain valuable materials but also potentially harmful substances. It is important to follow local regulations and return 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.
