Infineon Technologies boasted that its CoolSiC MOSFETs silicon carbide (SiC) power modules were used in the Europe's most powerful 400 kW DC chargers for electric cars, deployed by Repsol in October 2019 in Spain, at Ugaldebieta in the Bay of Biscay region on the heavily frequented A-8 motorway.
The RAPID ST400 chargers were supplied by Spain-based power conversion group Ingeteam and use CCS Combo 2 plugs.
Currently, there are no commercially available electric cars ready to use 400 kW and such power levels were seen only in bigger heavy-duty vehicles.
One of the key elements of the ultra-fast chargers is the new SiC power electronics, which minimize the switching losses. At peak power, even 1% of loss is 4 kW, while at 5% it would be 20 kW of heat. The company did not reveal the efficiency of the charger though.
Dr. Peter Wawer, president of Infineon’s Industrial Power Control division
“SiC enables high switching speeds with lower switching losses. This results in shorter charging times and charging stations that are about one-third smaller, since considerably fewer components are required for cooling. With its physical properties, SiC can make an important contribution to electric mobility. As various consumer studies show, the acceptance of electro mobility very much depends on the availability of an efficient fast-charging infrastructure. We have proven that we can provide the underlying technology.”
Europe’s most powerful 400 kW DC charger: CoolSiC™ for ultra-fast pit stops
Jul 8, 2020 | Market News
Munich, Germany, and Bilbao, Spain – 8 July 2020 – Spain based power conversion group Ingeteam and Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) team up for best customer experience in superfast electric vehicle (EV) charging. Rated at 400 kW, the converter INGEREV® RAPID ST400 from Ingeteam is based on CoolSiC™ MOSFETs in an EasyDUAL™ 2B housing. A single charging point implements eight of Infineon’s FF6MR12W1M1_B11 modules. Depending on the charging capabilities of the respective car, an EV now only needs to stop for a minimum of 10 minutes for an 80% percent battery charge. This is comparable to refueling a conventional car with internal combustion engine.
The design of the INGEREV® RAPID ST400 converter has proven to operate successfully at real life conditions. Already last year, the first project integrating this technology was developed, implemented, and commissioned by IBIL, the leading recharge technology services company in Spain, for Repsol, the multienergy provider and leading spanish petrol station operator. Located at Ugaldebieta in the Bay of Biscay region, it was commissioned in October 2019 as a lighthouse project in the field of electro mobility. The facility on the heavily frequented A-8 motorway features four ultra-fast charging points. These units guarantee optimal distribution of the available power between the four vehicles that can be connected simultaneously. More importantly, the technology is flawless and operates without any major downturns since the start.
