Hi Everyone,
I know the max power that the MiniEV can take is 50kW, but does anyone know if I can charge my Mini with a 150kW charger? Will the Mini regulate the input to 50kW or will the 150kW charger blow up my car?
Just got a 150kW charger at work, wondering if I can try it.

Thank you,

Yes, you can safely use a 150kW charger.

When you first plug in, the SE and the charger have a brief conversation to negotiate power delivery. The charger tells the SE how much power it can deliver and the SE tells the charger how much power it wants. The charger will only provide as much power as the SE asks for, and they continue this conversation throughout the charging session. The SE will ask for more power or less power depending on several factors, including battery temperature and state of charge. As the battery gets closer to "full", the SE will ask for less and less power to keep the battery healthy.

This article shows a plot of the "charging curve", which illustrates how much power the SE asks for:

Thank you for your reply, MichaelC!
I got the same answer from a Mini employee yesterday. The onboard charger will regulate the max charging power.

Thanks again,

Level 3 max is 50 kW pushed into the car. The car after thermal losses will accept approximately 43-44kW to the battery, so plan accordingly. Your ideal charging on the mini is 5%-80%. 80%-90% is reduced to approx 20kW. This drops even more at 90%.

This is the same with Level 2 charging too. The mini will only accept 7.4 kW (USA) single phase 240V 32A (USA) or 22kW 3-phase Level 2 (EU). In the US that means approx 4 hr 0-100% in 70*F weather and 4.5-5 hr due to thermal management during 40*F or less.

Level 1 will be limited to the cord that comes with the car. Our destination car (first 10 delivered to USA) came with an Aptiv 10A 120V Level 1 charger. It's not expandable like the Tesla UMC and will only pull 1200W (1.2kW) and will only deliver approx 960W (0.96kW) because of losses. This means 28+ hours 0-100%. Charging speed reduced in lower temperatures due to thermal battery management (heat pump).

Hope this helps and you enjoy the mini as much as us!

I have 240V 32A at home and it takes me around 4 hours for a full charge.
I have 25kw/50kw/150kw at work, but only tried 25kw.
