Low-temperature charging protection is a crucial feature designed to prevent batteries from the harmful effects of charging in cold weather. When charging temperature drops below a certain threshold, usually around freezing point (0°C), the charging process is automatically paused or suspended. This preventive measure helps avoid problems like lithium plating or mechanical instability, which can arise in low temperatures and compromise the battery's performance and longevity. Charging can safely restart once the temperature returns to an acceptable range. By integrating low-temperature charging protection, Bely batteries with self-heating function can deliver reliable and efficient battery performance even in cold weather. This feature not only extends the battery's lifespan but also ensures safety and durability during charging, thereby optimizing overall functionality.

Bely batteries with self-heating function are specially designed with built-in heating films installed around the cells, providing effective heating capabilities and ensuring optimal performance and reliability even in extremely cold temperatures. The heating films is connected to a power source. Once activated,it converts electrical energy into heat energy. The generated heat is then distributed evenly throughout the battery, helping to regulate its internal temperature. The heating films in a heating battery can be controlled through various methods. There are two Temperature Sensors inside the battery that monitors the battery’s temperature and activates the heating films when it falls below a certain threshold (we normally set at 0℃). They continuously measure the temperature of the battery cells and transmit the data to the battery management system. This ensures the battery maintains a suitable temperature range for optimal performance.

As a professional LiFePO4 battery manufacturer, we recognize the importance of providing customized solutions that address the specific needs of our customers, particularly those who depend on electric products during winter months. Here are several reasons why self-healing lithium batteries might be necessary:

Reliable Performance in Cold Weather: Standard lithium batteries often fail to perform optimally in cold temperatures, resulting in decreased capacity and functionality. Self-heating lithium batteries, however, ensure reliable operation even in freezing conditions, delivering consistent power output for your electric devices when you need it most.

Extended Battery Lifespan: Cold temperatures can have a significant negative impact on battery life and long-term durability. Self-heating lithium batteries are engineered to counteract these low-temperature effects by minimizing stress on internal components, which helps extend the battery pack's lifespan. This ensures electric devices stay functional for longer, thereby reducing the need for frequent replacements.

Enhanced Safety: Extreme cold poses safety risks for lithium batteries, such as reduced efficiency, higher internal resistance, and possible cell damage. Self-heating lithium batteries help maintain stable operating temperatures, reducing the risk of thermal runaway and ensuring safe operation of electric products in cold weather.

Heated lithium batteries represent a significant advancement in energy storage technology. By regulating their own temperature, they deliver dependable power solutions even in demanding environments. These batteries are vital for maintaining optimal performance and safety across extreme weather conditions and critical applications.
