## Description

Real range, charging curves, winter performance, care tips — every detail of your EV battery. 65 vehicles · 13 charts · 3 languages · 100% free, ad-free.

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. Vehicle model names are used solely to describe battery chemistry, parameters, and charging characteristics — a nominative fair use. All data is sourced from public cell data sheets, EPA filings, and peer-reviewed research.
