87 miles yesterday, stopping at my parents for morning and then further up the road (A1M) to kid's birthday party. -4c to 1c, 330 Wh/mi, 3 mi/kWh. Washer fluid did work and I took it easy with family.
28 miles commute this morning, -6c, 380 Wh/mi, 2.6 mi/kWh, hammered at "70"mph set with AP up the M1. Windscreen washer fluid isn't coming out 😞, I need to buy some super strong concentrated to mix it in.
This morning, I kept an eye on trip display. Consumption started at almost 500 Wh/mi, this trip-average slowly dropping initially, then started dropping quickly after 20min, down to what I got eventually. Unsurprisingly if driving short journeys, get bad efficiency figure.
Leaf was at around 55%, after 12mi school runs on Friday which is much less than 2mi/kWh. So my wife also wanted to charge the Leaf due to freezing temperature. I charged both cars last night in 4 hour cheap period, 7 kW on Tesla and granny charger, ~2.4 kW on Leaf, plus conservatory dehumidifier, I pulled over 10 kW during most of 4 hour period. My energy monitor tells me outdoor (not through house interior fuse box) used 35 kWh to charge 2 cars.
With Chademo V2H installed, probably be looking at ~45 kWh in 4 hour cheap period if charging both cars, I'll be looking at install a linked smoke alarm and some fire suppression auto-break-on-heat thing before next winter.
