Here’s a Look at Audi e-Tron’s Big New Battery
Long range and fast charging are the keys to enabling the e-Tron to
compete in the growing electric crossover segment.

Fast charging is e-Tron’s claim to fame. Despite its 95-kWh
capacity, the battery can be charged through a 150-kW DC fast charger in
as little as 30 minutes at commercial stations. Home charging can be
accomplished in 8.5 hours from a 230 V AC household outlet. By employing
a second, on-board charger with the 230 V line, charge time can be
reduced to 4.5 hours. The second on-board charger will be available as
an option in 2019. (Image source: Audi AG)
Audi’s new e-Tron crossover utility vehicle is one of the most
highly anticipated introductions in the electric market, largely due to
its emphasis on battery technology.
The e-Tron, Audi’s first-ever all-electric, asks a lot of its
battery. Because the e-Tron is a rather large luxury vehicle, it needs a
big battery with lots of range and power, as well as speedy recharge.
“We have three main goals for the battery: long range, safety, and
a 150-kW charging function,” Benedikt Still of Audi told Design News
last week. “And we were able to do the fast charging because of the
sophisticated thermal management system we created to cool the battery
down.”
Indeed, Audi is the first to offer 150-kW charging. That number
gives it a faster charge rate than the Tesla Supercharger (135 kW) and
the newly announced Jaguar i-Pace (100 kW), enabling it to reach 80%
charge in as little as 30 minutes at a commercial station.
The e-Tron’s battery is significant for the electric car community
because it addresses the looming issue of charge time. With batteries
growing bigger, charge time is becoming more important for electric car
manufacturers.
