I have trawled through past posts & assembled the following info on my EV; would the ‘experts’ please check my understanding of the facts & proposed action:
My wall box (EVSE) has a capability of single- & 3-phase, 11kW, 16A, 240v; this equates to 3.6kW single-phase or 11kW 3-phase
My charge cable is rated as single-phase, 32A, 250v
My 2019 UK BMW i3 120ah is rated as fast & rapid charge, multi-phase, AC & DC; this equates to a maximum charge of 11kW 16A AC or 50kW DC; the EV is set to maximum charge & the battery is rated as 42.2kWh (96 x 120Ah x 3,667v)
It takes up to 12 hours to fully charge the EV from near empty @ 3.6kW single-phase
How to make my home charging faster?
(1) buy a 3-phase cable (cost £140); this will reduce the charge time to 10 hours, ie limited by 16A output of EVSE
(2) ask EVSE supplier to upgrade the system to 32A, reducing the charge time to 5 hours with 3-phase cable (most suppliers offer 32A at no extra cost to 16A option)
(3) anything else please?
I charged recently at a GeniePoint public charger rated at 50kW DC with CHAdeMO plug but only achieved 26kWh in 42mins, ie <40% charge to full. Is this the fastest I’ll get from a public charger? The ‘Living with BMW’ website says that I should get an 80% charge in 25mins from a 60AH DC 125A 50kW (400-480v) charger.
All advice will be appreciated.
