On October 28th, I picked up the 702 Pro and fully charged it at home (achieving a WLTP range of 569 km – all range figures in this article are based on the WLTP standard). During the process, I stopped at a third-party charging station once and spent 8 RMB on electricity, which was not a formal charging experience.
First formal charging
On October 9th, with a remaining range of 259 km, I went to a XPeng S2 charging station in the afternoon.
The process was very convenient. After selecting the charging pile in the app on my phone, I lowered the bollard, backed the car into place, and plugged it into the charging pile. The battery was not preheated, but charging began in about 30 seconds.
The peak power of the S2 charging pile was 180 kW. After the G9 started charging, the power immediately rose to 160 kW, then continued to climb slowly.
Five minutes into the charging process, a G3 arrived and started charging next to me, robbing me of 40 kW of power, which reduced the charging power to around 120 kW.
After 10 minutes and 22 seconds of charging, the range increased by 131 km (from 259 km to 390 km), and the energy consumption was 24.057 kWh.
Second formal charging
On November 11th, I went to Guangzhou for a meeting and took the opportunity to experience the power of a supercharger at the S4 charging pile on Xingsheng Road, Tianhe District, Guangzhou. Luckily, there were no other cars charging when I arrived, so no one was competing with me for power.
As we all know, the lower the battery level, the faster the charging. When I arrived at the S4 charging pile, the remaining range was 327 km, which is approximately 57.5% SOC.
The procedure before charging is the same as S2 charging pile, and the battery is not preheated.
After starting the charging, the power immediately soared to 260kw. When the battery level reaches 60%, it drops to 225kw, and when it reaches 68%, it drops to 180kw. When it reaches 73%, it will drop to 120kw, and when it approaches 80%, it will drop to around 110kw.
Finally, it took 10 charges and 28 seconds, charged 25.608 degrees of electricity, and increased the cruising range by 133km (327km->460km).
Summary of Two Charging
Although I have watched many G9 charging experience videos online, the experience of going to the charging station by myself is still different, and I feel it is fast. The existing S2 charging pile can basically eat power above 160kw before the battery capacity reaches 70%. A simple calculation shows that the 702 version G9 battery is 98 degrees, and it takes 49 degrees of electricity from 20% to 70%, which can be achieved by charging on the S2 charging pile for 18 minutes (of course, the premise is that there are no cars next to you fighting for power).
As for the charging speed of the S4 charging pile, it is faster, and the peak can reach more than 260kw when my battery capacity is still 56%. However, when I was charging, the battery SOC was too high to show the advantage of S4 charging pile over S2 charging pile. The next time I experience this S4 charging pile when the battery SOC is lower, I will show you a more complete charging power curve.
Follow-up Plan
-
Find a third-party charging pile that cooperates with XPeng with a high voltage (600V or 750V) to test compatibility and power.
-
Experience the S4 charging pile again when the battery SOC is lower.
