Shop the BMW Gen 3 Wallbox, But Note the Restrictions to Reach Max Power Output of 22KW
The BMW wall charger Gen 3 is a popular charging option for electric vehicles. It can provide up to 22kW of power, but it is not always easy to get that much power from the charger. In Australia, the maximum power output is 50amp, which means that it is not possible to get 22kW with only 50amp.
In Canada, the situation is similar. The Gen 3 Wallbox has instructions and dip switch settings for supply on the BMW NZ site, but it is not possible to get 22kW from a single phase supply. The maximum AC charging limit for the BMW iX is 11kw, which is displayed on the dashboard when charging.
When deciding between waiting for the Gen 3 or going with a regular 48/50A charger, it is important to consider that frequent fast charging may not be beneficial for the longevity of the battery pack. This is especially true for Tesla owners, as there is no data yet available for the BMW iX. If you want to be on the safer side, 11kW probably is better in this sense.
In Europe, 3 phases need 400V between phases at 32A for 22 kW. This means that 230V between N and 1 phase and 400 V between 2 phases are required to get 22 kW. However, the onboard charger of the iX is only capable of 11kw, so getting a 22kw output from AC would be pointless unless the onboard charger has been upgraded.
Overall, it is important to understand how much power you can get from your charger before making a decision. The Gen 3 Wallbox can provide up to 22kW of power, but it requires a 3 phase supply to do so. For domestic households, an 11kW single phase 32A (230V) circuit will charge the car overnight and may be more suitable than trying to get a 3 phase supply.
Finally, it is important to remember that frequent fast charging may not be beneficial for the longevity of the battery pack. If you want to be on the safer side, 11kW probably is better in this sense. It is also worth noting that the onboard charger of the iX is only capable of 11kw, so getting a 22kw output from AC would be pointless unless the onboard charger has been upgraded.
What is the BMW wall charger Gen 3?
The BMW wall charger Gen 3 is a wall charger that can provide up to 22kW of power. It has a maximum of 50amp, however it is not possible to get to 22kW with only 50 amp.
Is it possible to get an 11kV supply from a single phase power supply?
Yes, 50 amps of current on a single phase 220 V power supply gives you an 11kV output (50*220=11,000). However drawing a 50 amp current on a single circuit is huge and most houses are limited to 30 amp breakers.
Is it beneficial to do frequent fast charging for battery longevity?
General speaking, frequent fast charging is not beneficial to longevity of battery pack. This is general thinking for Tesla owners. The BMW iX is too new to have any data to back this, so if you want to be on the safer side, 11kw probably is better in this sense.
What is the maximum AC charging limit for the BMW iX?
The maximum AC charging limit for the BMW iX is 11kw. This can be seen on the dashboard screen when charging.
How much power can I get from a 3 phase power supply?
In EU, 3 phases need 400V between phases at 32A for 22 kW. This means 3 phases + N will give you 230V between N and 1 phase, 400 V between 2 phases. This would give you 3 (ph) x 230 (V) x 32 (A) = 22 080 W or 22 kW.
Can the onboard charger handle 22kw from AC?
The onboard charger is only capable of 11kw, so 22kw would be a mute point / wasted unless the iX has upgraded the onboard chargers to handle the 22kw from AC.
Is it possible to charge the BMW iX with a DC charger?
Yes, it is possible to charge the BMW iX with a DC charger. The maximum DC charging limit for the BMW iX is 200kw. This can be seen on the dashboard screen when charging.
What type of cable do I need for DC charging?
You will need a Type 2 Mennekes cable for DC charging. This cable has two pins and is compatible with all public and home chargers. It is also compatible with all electric vehicles that use the Type 2 connector.
