EV Charge Log

Features
Read full description

EV Charge Log is a simple, fast, and easy-to-use charging log for electric vehicle owners. It helps you track how many times you charge each month, especially when charging to 80%, 90%, 100%, or a custom battery percentage. When you open the app, you immediately see this month’s charging summary and quick buttons to log a new charging session with one tap. If you have already charged to 100% this month, the app shows a clear status. If you log 100% charging two or more times in the same month, EV Charge Log displays a warning so you can better understand your charging habits. Key features: Quickly log 80%, 90%, 100%, or custom battery percentages View your total charging sessions for the current month Track 80%, 90%, 100%, and other custom charge counts Get a warning when 100% charging is logged more than once in a month Browse charging history grouped by month Edit or delete individual charging sessions Add notes to each charging log Customize your vehicle name and quick log buttons Optional monthly reminder to check your 100% charge status Supports English and Vietnamese Local storage only, no account required EV Charge Log does not provide technical battery recommendations. It is only a manual charging log to help you remember your charging history. Battery recommendations vary by vehicle model, so always follow your vehicle manufacturer’s guidance.
