Range
The Mii has a relatively large battery pack for its overall size, which pays dividends in terms of range. SEAT officially quotes between 140 and 170 miles on the WLTP cycle, and having spent a week behind the wheel, we’d say that those figures are pretty achievable. The modest 81bhp motor limits the amount of charge you can drain from the battery and given that most Miis will be driving in urban environments, few will have reason to quibble with the range figure.
Battery
At the heart of the Mii is a lithium-ion battery that has a capacity of 36.8 kWh, of which 32.3 kWh can be used. The 60-Ah battery pack consists of 168 cells and is brilliantly packaged into the SEAT's floor area. SEAT says that the pack itself is just 30cm tall, which has allowed it to install it without altering passenger space or the luggage capacity. In terms of layout, the Mii's motor drives the front wheels via a single speed transmission. Advanced control electronics manage the flow of energy from the high-voltage battery pack to and from the electric motor.
Charging
The Mii can be recharged in three ways. The quickest method is via a CCS rapid charger, which can charge at a maximum rate of 40kW and can go from 20-80% in an hour. It can also be charged via a Type 2 connection at a maximum rate of 7.2kW. A 6 metre Type 2 cable (Mode 3) is included as standard.
Finally, the Mii can also be charged via a UK standard three-pin plug, but charging to 80 per cent takes 12 hours and 43 minutes.
