Armed with some working Torque Pro PIDs, an EVgo membership without the ridiculous $4.95 connection fees, and some moderate temps (65F), I headed to the 125 amp ABB-made EVgo station near me. The previous 3 DCFC sessions were marred by slow charge rates, so would the 4th time be any better?

The HV battery was plenty warm (62.6F according to Torque Pro), probably <50F the previous 3 times. SOC was 33% according to the station when I started charging.

Immediately got a 38 kW/100 amp charging rate right after plugging in. It climbed up to around 45 kW/125A over the next 5-7 minutes. Saw a peak rate of 46 kW according to the car during the session.

When SOC hit 53-54%, the Bolt ramped down to 100 amps and a 37-38 kW charge rate, where it stayed till the end of the 30 minute session.

So 33-66% SOC in 30 minutes. 20 kWh in 30 min for a total of $3 (10 cents x 30 min), or 17 cents/kWh.

I plugged in again for the heck of it, and charge rate went right to 38 kW. Stayed there till it hit 70% SOC, when it ramped down to 23/24 kW and 60-61 amps. Stayed there through 81% SOC, when I finally pulled the plug after 20 more minutes. Charged 9 more kWh.

This is great stuff! Looks similar to typical Bolt EV performance. Is Torque Pro able to output the time history data? I could totally geek-out with that.

Dang, just realized you can. Looks like I'll have to head back someday soon and test again with the logger running.
