Increased the grid connection from 20kW to 150kW
Key results
Emission-free construction site
Many construction companies aim to be more sustainable, but have trouble finding the charging infrastructure required to power their machines. This happened recently at a construction project at Bristol Airport, where Griffiths Construction was brought in to lead the project. They sourced a Volvo EC230 electric excavator from SMT, a top-of-the-range piece of electric equipment.
The excavator couldn’t fast charge on the available 20kW grid connection however. No problem though! A Greener battery can even power heavy equipment like a vibratory hammer or a tower crane, so an excavator provided little challenge. Greener quickly flew to the rescue.
Powering up the grid
The charger needed to power the excavator required 150kW. We connected a 318kW battery to the 20kW grid connection and set it to peak shave. This means the battery charges through the grid connection when it has excess energy, while supplying extra energy to the EV charger when the grid’s power falls short. With the battery, we could boost the grid connection to 150kW. This allowed the electric excavator to fast charge on-site, saving both time and emissions.
Normally, projects like these would use diesel generators. However, this creates a lot of pollution and they’re very noisy. Our Greener battery provided a sustainable solution, charging the excavator and powering the construction site. An emission-free construction site, thanks to SMT and Volvo’s innovative electric excavator and Griffiths Construction’s sustainability ambitions.
Realising an emission-free construction site is a lot easier these days. We also did this for Dutch Ministry of Infrastructure and Water Management, who needed to charge multiple electric machines simultaneously.
SMT came to Greener looking for a solution to the shortfall in power onsite to enable supercharging of their Volvo EC230 excavator. Greener looked into the power requirements for the EV charger and the sites available power supplies. The charger required 150kW and site only had a 20kW power supply available. By utilising one of our 318kVA batteries set to peak shave we were able to make it happen.
