US Patent 12071020 Electric vehicle service equipment adapter module to control added loads

This invention enables Electric Vehicle Service Equipments to control external electrical loads, such as water heaters. The parallel electric energy demand of the external load augments the remotely controllable energy demand for charging the vehicle creating a larger controllable demand than for charging the vehicle only. This larger demand is useful in responding to requests for ancillary service from the grid and can increase the revenue for regulation services.
