Does battery aging status affect optimal charging strategy?

The impact of battery aging status on the proposed optimal charging strategy is carefully examined. Results suggest that aging-aware optimal charging strategy is necessary to avoid the formation of lithium plating, extend battery life, and ensure safety, especially for aged batteries.

How to maximize battery lifespan?

To maximize battery lifespan, it is important to charge batteries at a slow rate, avoid overnight charging, and use chargers rated for around 1/4 of the battery capacity. Storing batteries in cool, shaded areas and avoiding high charge levels can help maintain their performance.

What factors affect battery aging?

The rate of battery aging itself depends on multiple external stress factors , which enables the operator to influence the aging behavior through the operating conditions. For the purpose of BESS operation, battery aging can be grouped into calendar and cyclic aging.

Why does charging a battery increase aging?

One reason is that charging a battery with high power raises the temperature, which leads to accelerated aging. Another reason is the increased risk of lithium plating. Besides temperature, charging power, throughput, and depth of discharge, other effects such as phase shifts also accelerate battery aging.

Do aging-aware charging strategies extend battery life?

Furthermore, the aging-aware charging strategies proposed here demonstrate their capabilities to extend battery life, avoid severe degradation (lithium plating) and thus ensure safety, especially for aged or second-life battery applications. 5. Conclusions
