Methods for using cycle life data to protect electric vehicle battery health during use of bidirectional charger

This invention describes a system that helps protect an electric vehicle's battery health while it's being used to supply power back to a building or grid. It works by collecting historical usage data from the EV battery, predicting the building's energy needs, and then deciding how much to discharge the battery. The system will only discharge the battery if its historical usage data indicates that doing so won't harm its long-term health.

Why it matters: Filed as Vehicle-to-Grid (V2G) technology was emerging, the intervening years have seen significant progress in V2G communication standards and the availability of granular battery data from EVs, making the claimed health protection more practical for widespread deployment.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, data integration, EV interface
