Ultra Fast EV charger takes less than 15 min
Nidec ASI's Ultra Fast Charger (UFC) hooks up to the national grid through charging towers with the intent of simplifying and accelerating the electrification process of infrastructures for supplying electric cars, and reducing operating costs.
The UFC works as a “buffer” between the electricity grid and the recharging tower and incorporates 160 kW·h of installed batteries with advanced power controls. It can be connected to low-voltage (LV) or medium-voltage (MV) grids and, against an energy requirement of only 50 kW, can supply 320 kW of power to a vehicle, thereby multiplying the power delivered by six compared to that drawn from the grid. The company says that this system allows batteries of new-generation cars to be rapidly recharged to 80% of their capacity in less than 15 minutes, guaranteeing the vehicles up to 500 km (310 mi) of travel. It also allows the recharging of two vehicles in parallel or three in series and has an efficiency of 95%. Nidec ASI’s recharging systems are designed to be supplied both from the electricity grid and from renewable sources, such as solar energy, and can be bi-directional: they can be used not only for recharging electric vehicles, but also the grid (vehicle-to-grid—V2G).
In addition to the UFCs, Nidec ASI offers LV charging stations with centralized batteries, through which 12 vehicles can be charged to 80% of their capacity in an hour, and MV charging stations, possibly without batteries, which can be used to deliver greater power and recharge numerous cars (more than 12 vehicles in an hour) simultaneously.
