A parky 5*c battery in South East London.
RWD 93kw battery
At 22% so unable to pre heat
A 15 min 60mph drive increased battery to 6% so a waste of time.
Porsche 350kw supercharger.
Charging rate at battery temperature
5*c 47kw.
26*c 95kw
32*c 150kw
35*c 66% charge decreases 103kw
39*c 80% charge 100kw
15% to 80% 44 mins from a cold battery standing start.
Conclusion: Don’t let charge fall below the pre heat disabling level 25%. Don’t bother driving to warm the battery up. Will take a long time better spent charging at the initial 47kw. Though you will spend half the time well below 100kw as the battery reaches optimal temp. Also it appears to throttle the charge to 100kw from c.65%.
