How to Maintain Power Batteries for Electric Heavy Trucks in Winters
In addition to careful drivers, power batteries in good condition can be regarded as another crucial premise that facilitates safe and comfortable winter truck driving. Nowadays, the pure electric heavy truck power system is mainly lithium-ion batteries. Due to its chemical characteristics, the low-temperature performance will be weaker than at room temperature. In that case, we must maintain our electric heavy truck power batteries in a proper manner during the winter days. How to do that? Scroll down to get the answers!
General Principles
- Proper winter care is essential for ROI: battery packs shall account for 30–40% of total vehicle cost.
- Proactive thermal and charging management are essential as cold temperatures accelerate degradation and reduce performance.
Thermal Management
- Park vehicles in insulated or temperature-controlled environments when not in use.
- Maintain battery temperature above 5 °C before driving to improve energy recovery and range.
- Avoid long-term exposure to extreme cold (e.g., −15 °C or below) to prevent extended charging times and reduced discharge capacity.
Charging Best Practices
- Preheat the battery before charging or plug in while parked to make sure thermal systems are active.
- Avoid high-current charging in low temperatures, which may damage the battery and shorten its lifespan.
- Expect 0.5–1 hour longer charging times in cold weather, as the charging power is automatically reduced.
- After daily operation, charge the battery immediately when it is still warm, which could shorten the charging duration.
Energy Recovery & Range Optimisation
- Remember, cold weather can reduce regenerative braking efficiency and increase power consumption.
- Use cabin heating moderately to conserve battery and extend driving range.
- Charge promptly when the State of Charge (SOC) drops below 30% to avoid deep discharge stress.
Preventive Maintenance & Monitoring
- Implement a winter-specific preventive maintenance schedule to detect early signs of degradation.
- Monitor key parameters, including temperature, SOC, charging cycles, and thermal system performance.
- Use smart battery management systems to adjust charging and thermal profiles dynamically.
Statistic indicates that proper winter maintenance can extend battery life by 30–50%. Other long-term benefits are various, which include but are not limited to reducing downtime, improving operational reliability, protecting warranty coverage, increasing total cost of ownership, and ensuring consistent fleet performance. With all the abovementioned reasons, we highly suggest you take action in the upcoming winter. Travel safe, Travel Sustainable.
