About EV Battery Health by ChatStick
Stop guessing about your EV's battery. Start managing it.
EV Battery Health is a premium, fully offline toolkit that turns battery anxiety into confidence. Whether you're a new owner, a used-EV shopper, or a high-mileage driver, it gives you the tools, habits, and knowledge to read your pack's health, slow its aging, and defend its value.
The interactive tools are the star of the app — everything works offline, with no account and no ads.
INTERACTIVE BATTERY TOOLS
• SOH Tracker — Measure your State of Health from range or capacity, log every reading, and watch the trend over time. Includes the exact at-home test method.
• Charging Ceiling Advisor — Get your ideal daily charge limit for NMC or LFP based on how far you actually drive.
• Degradation Risk Score — See how your climate, charging habits, and state-of-charge combine into a single battery-stress score, with the top fix.
• Real-World Range Estimator — Estimate the range you'll actually see today and split the loss into weather (temporary) vs. true battery wear.
• Used-EV Inspection Scorer — Run a 30-minute inspection, score the car against real benchmarks, and turn findings into price leverage.
BUILD BETTER HABITS
• A personalized Care Plan checklist, organized into phases — daily charging, health tracking, seasonal care, and records — with your progress saved automatically.
LEARN & TEST YOUR KNOWLEDGE
• 60 quiz questions (five per chapter) with instant feedback and clear explanations.
• Key Takeaways — the whole book distilled into the essential facts, chapter by chapter.
• A plain-English glossary of 30 key terms — SOH, LFP, NMC, calendar aging, cell spread, preconditioning, and more.
TRACK YOUR PROGRESS
• A dashboard with an overall progress ring, reading/care-plan/quiz breakdown, streaks, and a wall of achievements to unlock.
THE COMPLETE GUIDE, INCLUDED
• As a bonus, the entire EV Battery Health guide is built in — all 12 chapters with images, adjustable text size, bookmarks, and resume-where-you-left-off. Read it end to end or jump to the chapter you need. Fully offline.
WHAT YOU'LL BE ABLE TO DO
• Estimate your pack's SOH within a few points using a simple driveway test.
• Set charging habits that preserve range and save money.
• Tell real degradation apart from normal winter or highway range loss.
• Read a battery warranty and know which numbers matter.
• Inspect a used EV like a pro and negotiate from evidence.
PRIVACY FIRST
• Works 100% offline. No account, no sign-up, no ads, no in-app purchases. Your data stays on your device.
EV Battery Health is a practical, brand-neutral companion for every electric-vehicle owner. Understand your battery. Preserve it. Own it with confidence.
