800-Volt Architecture
An 800-volt architecture uses a battery and electrical system at about 800 V instead of 400 V, allowing faster charging and thinner cables.
What is 800-Volt Architecture?
It enables very high DC charging power at lower current. Cars such as the Porsche Taycan and Hyundai Ioniq 5 use it. On 400 V chargers, the car may need a booster or charges more slowly. Some 800 V cars can add 100 km of range in around five minutes at a suitable charger.
How it works
Doubling the voltage halves the current for the same power, reducing heat and cable weight.
Why it matters for your car
Charging speed also depends on the charger and battery temperature. High-voltage work needs trained technicians.
