About

EV Battery Guide

Read full description

EV Battery Guide is an independent educational tool for EV owners — built to help you actually understand the battery in your car. 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. Three languages: Full support for English, 中文, and 日本語. Switch anytime in-app. Privacy first: • No accounts, no email • No user data collection • No third-party analytics or ad SDKs • Your selected vehicle and language preference live only on this device Completely free: No subscriptions, no in-app purchases, no ads. All features are open from day one. Disclaimer: This app is not affiliated with any vehicle manufacturer.
