Audi E-Tron Electric SUV Charges At Sustained 150-kW Rate

Audi e-tron proves its 150 kW charging capability at a 175 kW charger
When Audi announced the e-tron, it promised charging capability of 150 kW (0-80% in around half hour), which is reasonable with its 95 kWh battery pack.

A recent presentation of the charging results recorded for a pre-production e-tron at a Fastned fast charging station proves that 150 kW is totally achievable. . . .

At the 175 kW charger, e-tron’s charging power depends on the state of charge (of course also on other factors like battery temperature). Starting below 30% SOC, charging power was at about 140 kW or so. Power was steadily increasing to 150 kW around 55% SOC and to maybe even 155 kW peak around 70%. Then the power drops a little bit and continues around 150 kW to nearly 80%. In other words, we can assume that the average from 30 to almost 80% is around 150 kW.

Before 80% SOC, charging power drops quickly to less than 110 kW at 82-83% SOC and then continues to decrease at a linear pace to 50 kW almost to full 100% SOC.

Overall, e-tron demonstrates great charging performance – one of the best that we have seen so far in a production car (pre-production, but it shouldn’t be much different in a production version). With 150 kW, the Audi e-tron is ready for the long-distance travel and with optional three-phase 22 kW on-board charger, it’s outstanding also for home/work/destination charging too. . . .

And here we have first reviews:
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
