CHARGING & INFRASTRUCTURE
TS : Can you share any successful examples of cost savings through bi-directional charging ?
GI : In February 2020 , Wallbox grew by more than 11,000 square metres and exceeded 650 workplaces , and a grid power of 400kW was needed , while that available was only 173kW . Instead of upgrading the grid infrastructure which would have cost more than € 500,000 , Wallbox developed SIRIUS , Wallbox ’ s pioneering energy intelligence solution , which harnesses the power of bi-directional charging .
SIRIUS enabled the integration of the electric grid with the company ’ s distributed energy resources ( DERs ) composed of 400kWp of solar panels , bi-directional EV chargers , 23 Nissan LEAF and 560 kWh stationary batteries , balancing all DERs in real-time to optimise the building ’ s energy consumption , reducing the company ’ s environmental impact and saving money .
By investing around € 415,000 in SIRIUS instead of more than € 500,000 for grid upgrades , Wallbox reduced implementation time from 12 to 4 months and saved more than € 85,000 per year in electricity bills .
