So I have had a few chargers DC whilst on the road, most have been short duration as I mostly home AC charge. Just thought I would put it out there for discussion/comment on what I have come across and hopefully save some peeps money. Some might think the fastest capable speed chargers 250 or 350kW will give the best bang for buck but this may not be the case for many? See the stats from the small experiment I did.
Today I used the brand new Evie 50kW charger in Castle Hill and approx 2 weeks ago I used the Evie 350kW at Seven Hills. Both days the Sydney temp was around the same. Battery was pre heated for a short time for each session but no way near the proper battery temp, max about 20 minutes, which more than likely really affected the 350kW speed.
For reference my car is a 2022 M3 RWD LFP battery.
Today EVIE 50kW Castle Hill:
SOC 56%
17 min
13.904 kWh
cost $5.56
max speed as reported by car was 48kW
2 weeks ago EVIE 350kW Seven Hills:
SOC 68%
17 min
15.496 kWh
cost $9.30
max speed as reported by car was 98kW
My thoughts are depending on SOC and if the battery has been pre-heated the DC charger speed/cost ratio should be considered.
A 50kW charger not when road tripping could be a goto?
