Overview
Long-duration LiFePO4 battery aging example showing the impact of depth of discharge, C-rate, temperature rise, and capacity fade over repeated cycles.
This example shows the effect of cycling-induced aging on a 12.8 V, 40 Ah lithium-ion battery module. It is ideal for storage and electrification audiences interested in lifecycle effects rather than only instantaneous battery response.
The battery is cycled over 1000 hours at different depths of discharge and discharge rates. The model shows how deeper discharge and higher C-rate accelerate aging, reduce capacity, and increase internal temperature.
This example gives the community a valuable storage post that speaks to battery research, BMS strategy, and electrification planning. It also introduces lifecycle thinking rather than only converter control.
Key Features
