Every all-electric BMW comes equipped with the Flexible Fast Charger. This portable device, compatible with any 120V or 240V outlet, delivers optimized charging wherever you go. You can charge from 0–100% in under 12 hours at a 240V outlet.  

The optional BMW Wallbox is the ultimate in electric convenience. With its robust and weather-proof design, it can be installed in your garage or outdoors and delivers Level 2 charging at 9.6 kW charging speeds (~30 miles per hour of charging, reaching its full charge in approximately 12 hours).  

When charging at public charging stations, no additional equipment is required. The standardized charging system in North America is called CCS (for DC Fast Charging) and J1772 (for L2 charging).

All public charging stations that have a CCS or J1772 plug are available to you. Your BMW’s navigation, as well as the MyBMW App, will show you public charging stations equipped with CCS/J1772 plugs.

A kilowatt (kW) and a kilowatt-hour (kWh) sound very similar, but there is an important difference. A kilowatt (kW) represents the rate of electricity usage – it is a measure of the total energy you use over a specific period of time, as opposed to a given moment. One kilowatt translates to 1,000 watts. A kilowatt-hour (kWh) represents the total amount of electricity used.

The measurement of energy used for electric vehicle chargers is in kilowatt (kW). The higher the kW, the more rapid the charging rate. Kilowatt (kW) can also be used to refer to the output of the electric motor.

The total battery capacity of an electric vehicle is measured in kilowatt-hours (kWh), or the total amount of energy stored in the battery. The larger the battery, the more range you can cover on a single charge. It is the amount of energy expended in one hour by a kilowatt of power, just like what you see on your energy bill.

Charging time at a public charging station is determined by battery size, maximum charging output and the remaining charge left in the battery when you plug in your vehicle. For electric vehicles, home charging and Level 2 public charging generally takes more time than with DC Fast Charging public stations.

For example, a BMW i4 can charge up to about 30 miles in 1 hour with a Level 2 (AC) public charger. In just ten minutes, a DC Fast Charger can give you a range of 108 miles.

Before departing on long trips, enter your destination into your vehicle’s navigation or your My BMW App, and it will assist you in finding and planning charging along your route.

When the destination is entered, the battery will adjust its exertion to the highest level of efficiency between charging sessions.

Similar to your cell phone, charging up your electric BMW before a day’s use is simple.

The amount of miles you drive daily will determine how much charging you will need. There is no need to charge the battery up to 100% every night – unless you have to rely on the entire driving range of your vehicle. Staying between 20% to 80% battery capacity should leave you with enough driving miles.

When not driving your electric BMW for a week or more at a time, leave the battery between 20% and 80% charged.

Keep in mind that how often and how long you should charge your electric BMW depends in part on what kind of home charging option you have and your daily driving needs. If you have convenient access to workplace charging, that may also impact whether you choose to charge your electric BMW fully every night.

How far you can go on a single charge will vary based on the vehicle’s battery capacity, driving conditions, your driving style, and charging habits.
