Why Do Lithium Batteries Have Heaters?
Lithium batteries often incorporate heating systems to maintain optimal operating temperatures, especially in cold environments. These heaters help prevent performance degradation and ensure reliable operation by mitigating the effects of low temperatures. Maintaining appropriate temperatures enhances battery efficiency and extends lifespan, making heated lithium batteries essential for various applications.
How do heated lithium batteries work?
Heated lithium batteries utilize integrated heating elements that activate when the battery temperature drops below a certain threshold. These heating elements convert electrical energy into heat, which is then distributed throughout the battery cells. This process ensures that the internal temperature remains within an optimal range for charging and discharging, thereby enhancing performance and safety.Chart: Functionality of Heated Lithium Batteries
