After a couple of weeks of eDrive40 possession we took the i4 on a (brief) journey from Phx metro to Tucson, est. RT ~ 250 mi. Vacation spot was son’s soccer sport so we had a tough arrival time and solely budgeted about an hour extra for the surprising. Somebody not-to-be named forgot to cost the automotive, thus we would have liked to cost on the best way there. I used to be curious if the automotive may make it with out stopping, if beginning with 100% battery. I used to be not sure how consumption can be affected by freeway speeds since my solely EV expertise was with my Tesla Mannequin 3 (single motor, 200 mi vary) and it appeared to drastically eat power when above the 70-75mph vary. I by no means did it lengthy sufficient for strong knowledge however throughout journeys from Phx to San Diego I observed that vary virtually ‘halved’ from 2mi per 1% to 1 mi per 1% by observing it over a 10-15 min span (flat hwy).
There’s an Electrify America about 40 miles from our begin so I made a decision to cost to 100% and monitor utilization from that time ahead. Our first expertise with Public Charging stations (non-Tesla) was Horrible. I’d learn enter from different customers so possibly no shock, however this simply sucked.
Cease #1: Electrify America: Complete 4 stations, 2 unavailable, 1 in-use.This was the primary time I used EA and it stopped a couple of minutes after beginning (2kW added) with a “Charging session error.” I unplugged considering I wanted to reset it and the display screen then confirmed Unavailable. Uncertain why it stopped – we tried ready within the automotive with the A/C on, may which have affected use?? It was ~ 100 deg F so A/C wanted. So now the one station is already in use. I looked for subsequent closest charger and located one about 4 mi away.
Cease #2: EVgo: Complete 1 station, 1 accessible. (Presently at 38%)The station had a bank card slot nevertheless it didn’t work so I wanted to obtain their App and setup an account. Household not sure if the A/C had something to do with the primary situation in order that they waited below a tree, fairly sad at this level (I want I had taken an image). We felt our schedule was now in danger so my spouse calls the coach hoping he hasn’t handed us but and may cease and pickup our son, which he did. An Audi E-Tron pulled up subsequent to me and appeared a bit pissed off there was just one station. They go away. After 15 min I observed it’s solely charging at 47 kW and determined to abort; I defined to my household it’s too gradual and we’d miss the sport. I made determination to proceed on the freeway towards Tucson and gamble/cease at one other EA about 60 miles nearer to vacation spot.
Cease #3: Electrify America: Complete 10 stations, 7 unavailable, 3 in-use. (Presently at 30%)Similar Girl in E-tron is there at one of many stations and is signaling to me it doesn’t seem like working for her. A man in Porsche Taycan seems like he’s about finished charging so I ask him standing and he says he’s having hassle and tells me solely two stations work; together with the station with E-tron. He hasn’t began but, will get pissed off and leaves … his station now states Unavailable. Girl in E-tron isn’t in a position to get hers to work, strikes her automotive and appears for one more station regardless that the remaining say Unavailable. I resolve to offer her station a strive … after a couple of minutes my spouse bolts into the Outlet Mall (it’s sizzling outdoors) and it seems to be charging! Girl in E-tron is out of luck making an attempt different stations and leaves once more. EA App doesn’t present my automotive is charging however MyBMW App reveals its charging and I can see % going up so seems to be good to me .. I am going into Mall space on the lookout for spouse. 52 minutes later I’m at 99% (61.2 kWh delivered @ $0.43/kWh). TRIP DATA RESET
TRIP SUMMARY:Beginning with 99% Cost I drove to vacation spot and again house, virtually all freeway miles. I had A/C on, stored regular pace round 80 mph (75 mph pace restrict), Eco Professional and Drive mode ‘B’ (and tire strain at goal +/- 1 psi)
Complete Miles pushed = 133.6 mi
Complete Battery utilization = 40% (began at 99%, ended at 59%)
Avg 4.0 mi/kWh
I perceive consumption isn’t linear throughout the vary, nevertheless I can use this information to estimate freeway vary accessible: 133.6 mi per 40% = 3.34 mi / % –> Complete Estimated Freeway Vary = 334 miles
Subsequent street journey alternative I’ll enhance pace a bit and maintain at 85 mph to see how/if that impacts effectivity.
