ForeVolt is a physics-based battery degradation and lifetime modelling tool for engineers, researchers and advanced users. It simulates calendar ageing, cycling fatigue, lithium plating, power fade and usable energy loss to predict long-term State of Health under real operating conditions. Unlike simple cycle counters, ForeVolt models the underlying electrochemical stress mechanisms that drive capacity loss and resistance growth. Key features: • Long-term State of Health and End-of-Life projection • Knee-point detection for accelerated degradation regimes • Power capability and usable energy modelling • Temperature, depth-of-discharge, C-rate and storage condition inputs • Calendar vs cycling vs plating contribution breakdown • Sensitivity analysis to identify dominant ageing drivers • Interactive charts with zoom, probe and regime visualisation • PDF report export for sharing and documentation ForeVolt is designed for: • EV and battery engineers • Energy storage consultants • Researchers and students • Fleet and asset managers • Advanced enthusiasts who want realistic lifetime modelling All simulations are based on established degradation physics and Arrhenius-type stress acceleration, not simple rule-of-thumb curves. A free demo allows exploration of the model. ForeVolt Pro unlocks full interaction, presets, advanced analysis and report export. Subscription Information ForeVolt Pro is an auto-renewable subscription. • Title: ForeVolt Pro • Duration: Monthly / Annual (as listed) • Price: As shown in the App Store • Auto-renews unless cancelled 24 hours before period end.
