Is it quicker to charge with a dedicated EV charge point than with a domestic 3 pin wall plug?

Our smart home charge points are capable of charging up to 7.4 kW with a single-phase electrical supply (vast majority of UK homes) and up to 22 kW on three-phase electrical supplies. (Three point pin plugs carry ~2.3kW)

Standard 3 pin wall plug: 
The standard household outlet in the UK typically have a maximum power output of 2.3 kW. This can vary depending on factors such as the electrical standards and the quality of wiring in the building. 
  
Shell Recharge home charge point:  
Using a single-phase electrical supply, Shell Recharge home charge points in the UK can charge with speeds of 7.4 kW, depending on the specific model and configuration. 
  
So ratio= Shell Recharge charge point / 3 pin plug. 
  
Ratio = 7.4/2.3 = 3.2. Therefore the Shell Recharge 7.4 kW home charge point can charge an EV approximately 3.21 times faster than a standard 3-pin wall plug in the UK. 
  
It's important to note that this calculation assumes ideal conditions and does not factor in variables such as charging efficiency or any limitations specific to the EV's charging system. Some cars have an on-board charger that limits the power accepted to the EV. Therefore, even though the charger can provide 7.4 kW, the EV may not. Check your owner's manual if your car can accept 7.4 kW AC power.
