I am planning a 500 km (~310 miles) road trip with my 94ah i3. There are DC charging stations every 100 km except for a 145 km (~90 miles) part. I planned the trip in ABRP with speed adjustment on but otherwise default options. When it lowers the speed to 90 kmh (~55 mph) in that difficult part it predicts that I will safely arrive at a charging station with %11 battery left, and when it lowers the speed to 100 kmh with %5 battery left.
I haven't used ABRP before, so I don't have any ideas about how accurate it is regarding its predictions. I also use my i3 for short trips within the city only and I don't have much experience with speeding with it etc. I noticed that it uses 5.6 km/kWh (3.5 mi/kWh) as a reference consumption, I usually see around 7.2 (4.5), so I am also hoping it underestimates the range rather than overestimating it.
I asked this very same question on Reddit and a user told me fast charging 4 times a day may be detrimental to the battery. I searched here and Reddit for people who had completed a similar trip with only DC charging and I couldn't find any.
What do you say? Is this a safe trip to try (can I complete the 145 km part)?
What about fast charging 4 times a day? Is this something I should avoid at all costs? Is it really different than charging 4 times in let's say in a month or a year? I rarely used fast charging except for the first year I've owned this car.
Note: I bought the car in 2018, drove it for almost 20000 km (~12000 miles). I checked the battery status today and Batt. Kappa. max is 29.6 kWh.
