This from 2011 - https://www.greencarreports.com/news/1061086_roving-recharge-truck-from-nissan-to-aid-dead-electric-cars The NRMA/RAA/etc roadside assist concept continues, with a portable battery-on-a-truck to recharge your stranded car if you fail to plan your journey > I hadn't realised a fast charge required such high currents.

There may be scope to have that increased, and install another circuit - Ausgrid at least permits up to 100A from a single-phase supply. But in any case, a standard 15A power-point (3.6 kW/hour) would charge that whole 40kWh leaf battery overnight from empty to full in 11 hours. As pointed out earlier, most commonly you'll plug in to top up after using maybe 1/4 to 1/2 a charge during the day - plug in and set a timer to start charging at 10pm when off-peak charges start, in most cases you'll be full before you wake up, or at least will have sufficient charge for the days activities, without needing any specialised outlet at all.
