600 miles over 2 days in the i4

BIMMERPOST

So I had some meetings I had to attend in San Antonio on Tuesday morning. I live in North Dallas. Here’s my experience. Driving 300miles on consecutive days. In summary, I wouldn’t hesitate to do a 300mile trip again that was planned. But, unless I had a lot of spare time, I’m less sure than before that I would want to go cross country where timeliness is a factor. There is just too much dependency on chargers working and being available – the car itself is a gem though.

Recommendations:
– Plan your route and stops. Use the restrooms and food stops near the charging stations for best time efficiency where possible.
– Usually you can only eat fast food. Since each charging stop will just be 30 min.
– Have some padding in case chargers are full or not working (I never had an issue with having to wait).
– Drive with Adaptive Braking mode on highways. This is the only mode I can see that has zero regen (regen is inefficient since you don’t recover 100% of energy back).
– Speed. I drove with DAPP set to 5mph above the speed limit.
– If unfamiliar with EA chargers, allow time for learning to use those. I think it takes about 5-10 times using them before you become an expert to deal with all scenarios.
– Average usage about 3.5 miles per kWh. Tailwinds and Headwinds I think caused variance.
– Temperatures much above or below 70F will probably cause more power usage.
– Eco Pro Mode was too uncomfortable for us climate wise.

Dallas Department: 2.40pm Monday. SOC 78%. Temperature about 75F.
Charge stop 1: Waco. Charged from about 30-80%. 24min. 39kWh. Charge speed 150kW initial to 60kW at end.
Dinner stop: picked up Jimmy John’s. Took about 10 min. My son specifically wanted Jimmy John’s.
Charge stop 2: Austin. Charged from about 25-50%. About 12 min.
UT Austin: passed UTA at about 6.40pm (4 hours after leaving)
Arrive North San Antonio: 7.45pm. SOC 22%. Average speed including stops about 60mph. Average consumption about 3.7miles per kWh.

I checked into the hotel, then I went to the charger in San Antonio to get back to 80%. That took just under 30 min. If I lived in San Antonio, I may have just plugged it in at home.
