Factory Energy Management through Coordinated Control of EVs and HVAC Systems

With the large-scale integration of renewable energy in the future, parked electric vehicles (EVs) and heat pump equipment such as air conditioning systems are expected to serve as powerful resources for balancing electricity supply and demand. This technology implements a cloud-based energy management system at a factory equipped with self-consumption photovoltaic generation, where EV charging and discharging are coordinated with HVAC control. As electricity demand approaches the contracted capacity, the air conditioning system is controlled by zone according to predefined priorities, and electricity is discharged from EVs when necessary to suppress peak demand. As a result, workplace comfort is maintained while ensuring that EVs remain readily available for use when needed, enabling a reduction in electricity costs without compromising usability.
