Lithium Iron Phosphate batteries widely known as LiFePO4 have gained popularity due to their excellent thermal stability long cycle life and consistent performance One key factor that affects the efficiency and lifespan of these batteries is their full charge capacity
In this article we will explore what full charge capacity means for LiFePO4 batteries how it changes over time and how to monitor it effectively using data visualization
What is Lifepo4 Full Charge Capacity
The full charge capacity refers to the maximum amount of charge a battery can hold after being fully charged It is usually measured in ampere hours Ah and gradually decreases as the battery ages Monitoring this capacity is essential for determining the health and expected life of a LiFePO4 battery
Factors Affecting Lifepo4 Full Charge Capacity
Several elements influence how the full charge capacity of a LiFePO4 battery evolves
