What's inside:
• Open-Circuit Voltage (OCV) vs SOC curves — see your battery's true voltage behavior
• DC fast-charging power curves — understand the CC→CV transition and why it slows down
• BMS buffer visualization — your "100%" isn't really 100%
• Capacity retention prediction — how much will be left in 5 or 10 years?
• Cycle life vs depth-of-discharge — why shallow cycling lasts longer
• Lithium plating risk heatmap — what to watch out for in cold weather
• Winter range loss waterfall — where exactly does the range go?
• Speed × temperature energy matrix — the dual cost of highway and cold
• Cost-per-mile comparison — home charging, fast charging, and gas
• 13 interactive professional charts — built on public cell datasets
Coverage:
65 popular EV configurations across 7 distinct cell chemistries (LFP / NCA 2170 / NCA 18650 / 4680 / NMC / LiCoO₂), with chemistry-specific recommendations for each.
