About Charging the BMW iX3

It is quick. But that’s still slow

By Gary S. Vasilash

According to information about the new BMW iX3 (the UK version) we learn such things as the fact that there are 188 prismatic cells in the battery that have a gravimetric energy density that’s about 20% higher than that of the previous pack.

There is BMW’s fifth-generation eDrive technology that brings along a charging unit that provides power to both the 400V battery and the 12V on-board power supply.

As for the charging, when using AC it will permit single- and three-phase charging at up to 11 kW.

However, when plugged into a DC fast charger, it can charge at up to 150 kW. This means it can go from a 0% state of charge to 80% in 34 minutes.

There is another set of numbers that are striking. The BMW iX3 can charge the vehicle so that it can travel up to 62 miles (based on the WLTP test cycle, which is generally more generous than EPA figures) in 10 minutes.

While 10 minutes isn’t a whole lot of time, 62 miles of distance isn’t a whole lot of range.

According to the EPA, the average fuel economy for light-duty vehicles in 2020–cars, pickups, and cargo vans less than 8,500 pounds GVWR and SUVs and passenger vans up to 10,000 pounds GVWR—was 25.7 mpg.

The flow at your local gas pump (assuming you’re in the U.S.) is limited to 10 gallons per minute.  Which means that a light vehicle can get 257 miles of range in one minute.

Somehow people are going to have to get used to spending more time at a service station.
