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.
