But with most existing charging stations based mostly on 400-volt programs, is there still an advantage for autos with 800-volt architectures?
Industry experts say yes, however vehicles will have to have an 800-volt-dependent charging infrastructure to just take whole gain.
“Considerably of the existing DC quick charging infrastructure is for 400-volt motor vehicles,” stated BorgWarner’s Husted. “To allow the faster charging that 800 volt allows, the most current technology of high-voltage, high-electrical power DC quick chargers will be necessary.”
Which is not an concern for property charging, but the greatest-pace general public charging networks so far are restricted. Reich believes it will be a distinct concern for freeway charging stations.
“The refill has to be as rapid as fueling up at a gasoline station,” he mentioned. “This is the use circumstance” for 800-volt charging.
Europe is looking at the rise of such networks.
Ionity is a multi-automaker partnership with a variety of 800-volt, 350-kilowatt highway charging factors.
“A 350-kW charger translates into five to seven minutes charging time for 100 km,” stated Otmar Scharrer, senior vice president electrified powertrain technological know-how at ZF. That’s about the exact time as a coffee split, he pointed out.
“This is seriously a activity-changer,” he reported. “This is some thing that will generate acceptance of e-mobility.”
According to a recent report from Porsche, it takes about 80 minutes to insert 250 miles of selection at a normal 50-kW, 400-volt station. That time drops to 40 minutes at 100 kW. If the charging plugs are cooled — introducing cost, excess weight and complexity — that time can slide to 30 minutes, Porsche mentioned.
“A shift to a greater voltage is hence unavoidable in the quest to reach charging situations in the wanted corridor,” the report explained. It would drop to about 15 minutes with 800-volt charging, the automaker claimed.
Having into account the time to pay back, “the aim of ‘charging like filling up’ is consequently almost in arrive at.”
Audi says the A6 Avant E-tron principle, based on the same PPE architecture as the Taycan, can just take in sufficient electrical power in just 10 minutes at a rapid-charging station to travel about 186 miles.
