EV CHARGING FEATURE
NEW ULTRA FAST CHARGER FOR SPEEDY RECHARGING OF NEW-GENERATION ELECTRIC VEHICLES
T
he Ultra Fast Charger (UFC), an advanced system from Nidec hooks up to the national
grid through charging towers, simplifying and accelerating the electrification process of infrastructures for supplying electric cars, and reducing operating costs at the same time. This solution will help pave the way for the spread of electric vehicles, a market which many countries are still struggling to get off the ground, but one that has huge opportunities for growth in the near future. Electric cars still only account for 0.1 per cent
of the world’s automotive market. The widespread availability of infrastructures for the efficient recharging of the vehicles plays a central role in boosting the purchase of electric
cars. The Ultra Fast Charger developed by Nidec is a highly efficient solution, able to respond to the increased energy requirement demanded by the charging towers and the need to maintain the maximum stability of the electricity grid. The Ultra Fast Charger works as a ‘buffer’ between the electricity grid and the recharging tower, incorporating 160kWh of installed batteries with advanced power controls. It is the prototype of a new generation of ultra fast chargers, which can be connected to LV or MV grids and, against an energy requirement of only 50kW, can supply 320kW of power to a vehicle, thereby multiplying the power delivered by six compared to that drawn from the grid. Thanks to this system, the batteries of new-
generation cars can be rapidly recharged to 80 per cent of their capacity in less than 15 minutes, guaranteeing the vehicles up to 500km travel. It also allows the recharging of two vehicles in parallel or three in series, and has an efficiency of 95 per cent. 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, meaning they can be used not only for recharging electric vehicles, but also the grid - Vehicle-to-Grid (V2G). Nidec ASI is developing an entire portfolio of products to meet the needs of all market players, divided in three different formats: in addition to the ultra fast chargers, it also offers LV charging stations with centralised batteries, with which 12 vehicles can be charged to 80 per cent of their capacity in an hour, and MV Charging Stations, possibly without batteries, which can also be used to deliver greater power and recharge numerous cars (more than 12 vehicles in an hour) at the same time, such as a fleet of corporate cars, or trade vehicles in a logistics enterprise.
