Delta’s Europe headquarters in Hoofddorp, the Netherlands, is located in a building that is over 30 years old. When the building was first constructed, demand for EV charging was simply not a consideration. Its power configuration was thus limited, making substantial reconstruction difficult. However, in October 2021, Delta was able to install 16 chargers in the building’s parking lot by leveraging rooftop PV and energy storage systems. Since their activation, there have been zero power overload incidents, and the building’s total energy cost has been reduced by 5%. The key to this success lies in the implementation of DeltaGrid® EV Management.
According to a European Union survey on EV charging behaviors, there are 90% of EV owners charge their vehicle either at home in the evening after work or via EV chargers at their workplace in the morning. At Delta’s Europe headquarters, half of all employees worked from home in 2021 due to COVID-19 mandates. Despite only four to six EVs being charged in the parking lot during peak hours in the morning, electricity consumption from EV charging still exceeded 70% of the total office electricity use.
After Delta’s Europe headquarters analyzed the curve of its historic electricity use and predicted the EV charging demand, the company decided upon a series of actions. First, they installed 16 AC and DC chargers that can simultaneously charge 24 EVs. To help cope with the anticipated electricity demand, a 50 kW rooftop PV system was set up to generate approximately 42,300 kWh of green electricity each year. An energy storage system with 100 kW output power was also established to store up 293 kWh of electricity, with DeltaGrid® EV Management implemented as the core charging management system to regulate EV charging and solar power generation and energy storage.

In contrast to conventional charging management systems that focus on equipment monitoring, DeltaGrid® EV Management is a unified system that manages and controls chargers, electrical load, solar power generation, and energy storage. Thus, it achieves multiple goals for enterprises—uncompromised charging services, optimized power dispatching, and optimized electricity fee structuring, all while conserving energy and reducing carbon emissions. For a better user experience, Brand Management Division helped optimize the system's user interface last year. DeltaGrid® EV Management also integrates AI machine learning algorithms that analyze daily electricity usage information to derive the optimal long-term energy dispatch mode.
With current trends aimed at reducing carbon emissions, the demand for charging management systems will become more prominent and pressing. In the future, Delta will continue to assist commercial offices, factories, and old buildings with limited power configurations worldwide, helping them painlessly transition to an EV-friendly environment to bring about an era of low-carbon power grids and e-mobility.
DeltaGrid® EV Management is with an optimized user interface developed by BMD last year.
