A typical electric vehicle (60 kWh battery) takes just under 8 hours to charge from empty to full with a 7 kW Level 2 (L2) charger and just under 3 hours with a 19 kW L2 charger. Level 1 chargers can take days to reach a full charge. Level 3 chargers can fully charge an EV in 30 minutes or less but are impractical to install at your home.
Level 1 chargers take the longest to achieve a full charge, Level 3 chargers are the fastest.

An EV with a 60 kWh battery will take roughly 8 hours to charge from 0-100% on a 7.4kW standard home charge point. Rapid DC charging: 25-150kW This option takes charging speeds to the next level, providing power levels from 25-150kW. However, the most commonly used rapid charging speed is 50kW.
Keep in mind that charging is not linear, and State of charge (SoC) which is the level of charge of an electric battery relative to its current capacity plays a part. The resultant effect is the last 20-30% of the battery may take longer due to reduced charging speeds to protect the battery.
Let consider two EVs, one with a 40 kWh battery and another with an 80 kWh battery. If both cars are connected to a charge point capable of charging at max speed of 7.4 kW, the 40 kWh battery will take approximately 5-6 hours to charge fully, while the 80 kWh battery will take twice as long, around 10-12 hours.
An empty battery will take longer to charge than a battery already at 50%. Interestingly, the rate at which electricity is accepted declines as the battery gets closer to full. In other words, a depleted battery typically adds more miles in 20 minutes of EV charge time than a half-full battery.
