Installing EV charger systems with electric machines

Watch a video of the installation process here.

Kempower, in collaboration with EVRevolution — supported by Atlas Copco Group, Husqvarna Construction, Volvo Construction Equipment, and Sweden-US Green Transition Initiative — successfully installed a fully electrified Kempower Satellite Charging System from start to finish at its North America Headquarters in Durham, North Carolina.

The initiative is aimed to showcase the potential of sustainable construction practices by Building Electric with Electric. The EV charging project was installed using electric machines.

“Using electric vehicles reduces harmful pollutants that cause asthma and climate change. These benefits are increased when the electricity used to power the vehicles comes from clean, renewable sources” shared Heather Brutz, Clean Transportation program director, NC State University, who rallied alongside representatives from the Durham County Commissioners office, Greater Durham Chamber of Commerce and Research Triangle Cleantech Cluster to witness the installation.

“By displaying a fully electrified EV Charging Satellite, we aim to help demonstrate the feasibility of accelerating the transition to electric transportation if we all just work together,” added Joel Bulpitt of EVRevolution.

While the number of electric on-road vehicles ­and the need for charging infrastructure ­continues to rise in the US, there is an overlooked avenue for CO₂ reductions even before the chargers become operational. Using electric machines and building electric with electric, will reduce the carbon footprint within the construction phase. Air and noise pollution, as well as vibrations will also be reduced, benefiting the operators, job site, and neighbors.

The project involved:

• Installation of Kempower’s 600-kW Power Units with six charging plugs at two building locations on the Kempower campus.
• Kempower’s Dc fast-chargers can be equipped with CCS1, CHAdeMO and NACS connectors.
• The full commission by EVRevolution, of Raleigh, North Carolina.
• Electric equipment used: K 1 PACE power cutter: Husqvarna K 1 PACE | Husqvarna INT, LF 60i LAT forward plate compactor: Husqvarna LF 60i LAT | Husqvarna INT, Husqvarna WT 15i water tank: Husqvarna WT 15i | Husqvarna INT.
• Construction equipment used: Electric excavator and L25 Electric loader from Volvo Construction Equipment.
• Electric equipment from Atlas Copco USA:⁠ single-stage, oil-injected, rotary screw-type air compressor: H185 VSD.

The manufacturers provided onsite training and support and collected data that will be used to document CO₂ reductions and gain valuable feedback from the contractor.
