ZapGo and AS Green Cube Innovation enable ultra-fast charging units in Norway

The JV will provide charging rates between 350 kW to 1.2 MW

A joint venture between ZapGo and AS Green Cube Innovation of Norway will commercialise the world’s first operational storage units to enable ultra-fast chargers for battery electric vehicles, utilising ZapGo’s Carbon-Ion (C-Ion) technology.

The joint venture aims to significantly reduce the time needed to fully charge a car, truck, bus or ferry by enabling 350 kW to 1.2 MW charging without the need for costly public infrastructure investments. Rollout of the two initial charging units at AS Green Cube Innovation’s existing charging stations in the greater Oslo, Norway area will begin mid-2020.

“Norway is the ideal initial market for ZapGo’s ultra-fast charging technology, due to the high concentration of electric vehicles in use,” said ZapGo CEO Stephen Voller. “According to the Norwegian Road Federation, about 60% of new car sales in March 2019 were EVs. Drivers who live in apartments or travel long distances will require much faster charging at service stations, because they will not want to wait for hours queuing at public chargers and won’t be able to plug in at home.”

“ZapGo’s C-Ion technology significantly reduces the time required to charge batteries for cars, trucks, buses and ferries, while also reducing the need for costly public infrastructure investments,” said chairman of AS Green Cube Innovation Jon Erik Brøndmo. “The use of ZapGo’s C-Ion technology at our fuelling stations will cater to Norway’s EV owners by greatly shortening their charging time. It is a true win/win for Norwegian consumers, transportation companies, the public sector and the environment.”

The design goal of a 350-kW charger is to transfer around 100 kWh of energy in 15 minutes to a vehicle. 100 kWh is required to drive an electric sports utility vehicle (SUV) 300 miles (or about 500 km) at freeway or Autobahn speeds, with more than one passenger and with normal air conditioning or heating. To transfer 100 kWh in five minutes would require a 1.2-MW charger.

ZapGo is a member of the EV international standards body CharIn, which is also developing standards for 1.2-MW electric trucks with the design goal of transferring 1 MWh of energy to an electric truck in one hour. 1 MWh of energy is required to power a fully loaded 18-wheeler heavy truck for 300 miles (or about 500 km) at freeway or Autobahn speeds.

The new chargers have intelligence that recognise the type of vehicle and adjust the maximum safe charge rate. As vehicles become available that can be charged at these very high rates, the chargers will automatically switch to the higher rate. For existing vehicles like the Nissan Leaf that can be charged at 50 kW or the Tesla Model S at 120 kW, the chargers step down accordingly.

The ZapGo and AS Green Cube Innovation JV will store the electric energy at night and off-peak to provide EV drivers with cost-effective electricity. Vehicles will then be charged from the stored energy, not directly from the grid. This will also enable AS Green Cube Innovation to provide capacity to charge multiple vehicles at the same time, without upgrading the electrical connections to their sites.
