Why does the BMW i7 battery take longer to charge compared to other electric cars?

I have noticed that the BMW i7 battery takes significantly longer to charge compared to other electric cars. Is there a specific reason for this and is there anything I can do to speed up the charging process?

The BMW i7 uses a larger battery capacity, which can take longer to charge compared to other electric cars. One way to potentially speed up the charging process is to invest in a faster, high-voltage charger for your home or to utilize public charging stations that offer fast charging options.
