Introduction

Electric commercial vehicles are gaining popularity worldwide, but ensuring their stable operation in extreme cold weather is a significant challenge. CATL's (Contemporary Amperex Technology Co. Limited) new generation BC5 battery, known for its high energy density, long lifespan, and excellent environmental adaptability, has become the preferred choice for many electric commercial vehicle manufacturers. Meanwhile, EVLINK's 24kW water heater provides the best solution for these new-generation batteries in low-temperature conditions. This article details how the combination of the BC5 battery and the 24kW water heater enhances the operational stability of electric commercial vehicles in extreme cold weather.

Advantages of CATL BC5 Battery

The BC5 battery from CATL is a new generation long-life battery for commercial vehicles, offering the following key advantages:

• High Energy Density: The BC5 battery can store more energy in the same volume, significantly increasing the vehicle's range.
• Long Lifespan: Optimally designed, the BC5 battery has a long cycle life of up to 15 years, reducing replacement frequency and maintenance costs.
• Strong Environmental Adaptability: Whether in high-temperature environments or extreme cold conditions, the BC5 battery's thermal management system maintains high performance, adapting to various extreme environments.

Thermal Management Challenges in Extreme Cold Weather

Cold weather slows down the chemical reactions in batteries, leading to decreased capacity and output power. Therefore, an effective thermal management system is crucial to ensure battery stability in low-temperature environments. EVLINK's 24kW high-voltage water heater uses a heating strategy to uniformly warm the battery pack, ensuring its normal operation in cold conditions.

Role of EVLINK 24kW Water Heater

• Efficient Heating: With a 24kW power output, the water heater can quickly heat the battery pack, reducing preheating time and enabling the battery cells to quickly reach a stable charge and discharge state.
• Intelligent Control: Integrated with a PID system, the heater automatically adjusts the heating power according to the temperature required for battery thermal management, ensuring that the coolant temperature remains within the battery's stable and healthy range.
• Safe and Reliable: EVLINK's heater features multiple protection functions, including overheat protection and undervoltage protection, ensuring the safe operation of the battery thermal management system.

Practical Application Cases

The combination of CATL's BC5 battery and EVLINK's 24kW water heater has already been applied by various electric commercial vehicle manufacturers. In cold regions, these vehicles use the high-voltage coolant heater to assist in heating, ensuring the battery remains within the optimal temperature range, thereby maintaining stable operation and high efficiency.

Conclusion

The combination of CATL's BC5 battery and EVLINK's 24kW water heater provides a solid guarantee for the stable operation of electric commercial vehicles in extreme cold weather. The efficient thermal management system ensures that electric commercial vehicles maintain high performance and reliability in various extreme weather conditions. We believe this technological combination will drive the success of electric commercial vehicles in a broader market.
