FAQs 6

What is a battery retention rate?

In simpler terms, it represents the remaining capacity as a percentage of the initial capacity, initially set at 100%. During cycle testing, which assesses battery degradation through repeated charging and discharging, the capacity retention rate serves as a key evaluation metric.

What is the difference between energy retention rate and energy recovery rate?

Energy retention rate measures a battery’s ability to hold onto its charge during storage, while energy recovery rate measures its ability to regain its capacity after being stored for a certain period. Why are testing standards like IEC62133 and UN38.3 important for energy storage cells?

What factors affect the capacity retention rate of a battery?

Several elements impact the capacity retention rate of a battery apart from cycle count. These include the charging and discharging rates during cycles, ambient temperature, and others. The decline in capacity retention rate can be estimated using degradation coefficients such as Kc in cycle tests and Kf in float tests.

How do you calculate the retention capacity of a battery?

Therefore, the remain retention capacity of a battery after certain cycling can be calculated by the equation: capacity retention = (CE)n, where n represents the cycle number. If a full battery cycles 1000 times with more than 90% capacity retention, the CE would be >99.99% (Fig. 23 d).

What does a high energy retention rate mean?

A high energy retention rate indicates that the battery can maintain its capacity even under extreme temperature conditions, while a low retention rate suggests that the battery’s performance may degrade in certain environments. What is the difference between energy retention rate and energy recovery rate?

What is EV capacity retention?

This measure not only guides end-users on the life expectancy of their EVs but also provides manufacturers with a clear standard to aspire to. In simple terms, capacity retention refers to the ability of a battery to maintain its storage capacity over time and through various charge-discharge cycles.
