SoH Checker vs EV Battery Guide

Monitor your electric vehicle's battery health with SoH Checker – the simple app for calculating your EV battery's State of Health (SoH). HOW IT WORKS SoH Checker uses data from your vehicle's onboard computer to calculate your battery's current health status. Take a normal consumption drive and enter the values – the app does the rest. MAIN FEATURES - Precise SoH calculation based on consumption data - Estimated range with current battery capacity - History tracking for multiple measurements - Support for multiple vehicles - Consideration of heating/air conditioning - Customizable consumption units (kWh/100km, Wh/km, kWh/100mi, Wh/mi) - Fully multilingual (German, English) PREMIUM FEATURES - Unlimited vehicles and measurements - History chart with trend line - Edit and delete measurements - PDF export of complete history - Advanced statistics PRIVACY Your data stays on your device. SoH Checker does not collect personal data and sends nothing to external servers. Full control over your data. SIMPLE & ACCURATE No complicated measuring devices needed – just the data from your onboard computer. Perfect for all electric vehicle owners who want to keep an eye on their battery condition. Whether Tesla, VW ID, Polestar, Hyundai IONIQ, or any other electric vehicle – SoH Checker works with all EVs where you have access to SoC (State of Charge), consumption, and distance traveled. FOR WHOM? - Electric vehicle owners who want to monitor their battery - Used car buyers for battery inspection - EV enthusiasts who track their data - Anyone who wants to know: "How healthy is my battery?" WHY SOH MATTERS State of Health shows you how much capacity your battery still has compared to new condition. An SoH of 90% means 90% of the original capacity is available. With regular measurements, you can identify trends and document depreciation. Start now with your first measurement and keep track of your EV battery's health!

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.
