Big battery allows fast charging, even in remote places

The Dutch company NXT Mobility is starting with the installation of enormous batteries that will make it possible to offer ultra fast chargers. Even with a small consumer connection. According to NXT the rollout of ultrasonic charging up to 320 kW will no longer be hindered by the ‘increasingly limited grid capacity’.

Everyone with a electrical vehicle knows: fast charging is key while on the road. Especially when you’re driving across countries, while on a business trip or holiday. “For the EV revolution to succeed, a more than proportionate growth in the number of charging points is needed,” reports NXT.

Shortage of power

“In view of the increasing electrification of the vehicle fleet, we are going to equip our own petrol station network with fast chargers,” says Pieter Talsma, director of GP Groot fuels and oil trading, the mother company of NXT.
“The initial survey showed that in many locations the capacity of the electricity grid is too limited to realize fast chargers. The shortage on the power grid will only increase in the coming years. We are even receiving letters from grid managers stating that increasing the capacity of existing power connections will not be possible in the coming years. This is holding back the much-needed expansion of fast charging capacity and slowing down the energy transition. So we looked for a solution and found it in ADS-TEC Energy’s ChargeBox ultrafast charging systems.”

Competitive

With this ultra-fast charging system, it is possible to power one car with a charging speed of 320 kW or two cars simultaneously with a charging speed of 160 kW. Erik Metselaar, business manager of NXT Mobility, explains that the battery generates five times more power than the electricity grid provides. “The system, like a power bank, charges at low power and then transfers the stored energy ultra-fast to electric vehicles. With a 50 kW power connection, up to 320 kW can be charged ultra-fast.” According to Metselaar, the systems are competitive with conventional fast chargers in terms of total life, cost and operation.

GP Groot aims to implement at least 50 ChargeBox systems in the first year of the partnership. The first Dutch ultra-fast charging system will soon be put into operation at one of the NXT Mobility gas stations.
In addition to gas stations, NXT will also target transport and cab companies, operators of fast charging networks and utility companies for sales. In addition, the company will soon introduce a similar system that can also be used to charge with 22 kW input power.
