Smart electric vehicle (EV) charging and grid integration apparatus and methods

This invention describes an in-vehicle system that accurately determines an electric vehicle's battery charge level using a specific voltage-based calculation method. This system then wirelessly communicates the charge status to an external power grid management system, enabling smart charging decisions and potential grid balancing.

Why it matters: Filed when EV adoption was low and grid integration (V2G) was nascent. Today, widespread EV adoption and maturing V2G standards make such smart grid interaction highly desirable and technically feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom electronics, software, EV integration, battery calibration.
