Lithium battery electric locomotives are equipped with advanced and efficient power systems, with lithium batteries being the core component that ensures long-lasting, high-performance operation. To extend the lifespan of the lithium battery and ensure the safe operation of the vehicle, drivers and maintenance personnel should follow these professional maintenance guidelines for the battery.

1. Pre-Use Considerations:

Before installing the lithium battery, carefully check the battery’s voltage and the state of charge (SOC). The SOC should be within the normal range of 30% to 90%. Additionally, confirm that the positive and negative terminals of the battery pack are properly matched with the locomotive’s terminals to ensure a safe connection.

2. Proper Startup and Shutdown Procedures:

To ensure proper operation, use the correct procedures for starting and shutting down the vehicle. To start the vehicle, press and hold the green button for 3 seconds. To shut down, press and hold the green button for 5 seconds. When shutting down, ensure the battery pack is securely connected to the locomotive, and the controller is in the “0” position before starting to avoid damaging the connectors.

3. Battery Charging:

During operation, if the vehicle’s alarm sounds, this indicates the battery needs charging. Charge the battery promptly to prevent the vehicle from stopping mid-operation. To charge the battery, first connect the charging plug to the battery pack, then turn on the charger. After charging is complete, turn off the charger’s main power and then disconnect the battery pack from the charger.

4. Battery Pack Maintenance:

The lithium battery’s discharge temperature range is from -10°C to 45°C. Always use the battery within suitable temperature conditions, avoiding exposure to humidity and direct sunlight. If the vehicle will not be in use for an extended period, charge the battery every three months to maintain an SOC of 50%. During the loading and unloading of the battery pack, handle it with care to avoid severe vibration and impact.

5. Troubleshooting and Handling Failures:

In the event of a fault, the display screen of the battery pack will show the fault details and trigger an alarm. If this happens, immediately contact the manufacturer or a professional technician for assistance to prevent further damage.

By following these maintenance guidelines, the lithium battery in a lithium battery electric locomotive can maintain optimal performance, extend its lifespan, and improve the overall reliability and safety of the vehicle. Regular maintenance is critical to ensure the long-term, efficient operation of the locomotive.
