Winter poses unique challenges for electric sightseeing buses, with the decreased range being a common concern.
As the temperature drops, battery capacity is naturally affected, with a 1% decrease for every 1℃ reduction from the standard 25℃.
In cold environments, the battery’s cycling ability decreases, and factors such as increased electrolyte viscosity and chemical reaction resistance can lead to shorter charging times (as low as 70% below 5℃), reduced charging (60%-70%), and discharge (50%-60%) levels, resulting in a noticeable decrease in driving range.
To optimize the performance of electric sightseeing buses in winter, consider the following tips:
Optimal Charging Practices: Charge the electric sightseeing bus to full capacity during each charging session, avoiding mid-charge interruptions. This practice helps maintain battery health in colder temperatures.
Timely Recharging After Use: After covering distances exceeding 15 kilometers, ensure the electric sightseeing bus is recharged on the same day. Timely recharging is crucial for sustaining battery life and performance.
Prevent Discharge During Storage: Avoid storing the electric sightseeing bus with a partially discharged battery. Before extended periods of non-use, ensure the battery is fully charged, and repeat this process every 15 days during storage.
Regular Battery Maintenance: Keep the battery surface clean and dry, with securely fastened connections. Perform weekly checks to ensure proper battery function and address any issues promptly.
Prompt Detection and Handling of Battery Issues: If any abnormalities are detected in the battery, conduct timely diagnostic checks and address the issues to prevent potential damage.
Dealing with Individual Battery Damage: Battery damage often manifests in one or two cells initially. Promptly address any damage to prevent it from affecting other batteries in the fleet.
Safety Measures During Charging: During the first hour of charging, monitor the process closely. If the charging cable shows signs of heating or softening, indicating a divergence from standards, cease charging immediately.
Winter Range Considerations: Understand that a reduced driving range during winter is a normal occurrence. Inadequate charging during winter storage can lead to battery freezing and cracking.
By incorporating these winter care practices, you can ensure the optimal performance and longevity of your electric sightseeing bus fleet, providing a reliable and efficient experience for both operators and passengers alike.
