Charge point
Charging times


There are many types of electric vehicle charge points (EVCP) available, which charge vehicles at different speeds.

The speed of charge an electric vehicle owner will require needs to be based on how the charge point will be used and this will depend on the type of location it is installed in.

Take an office where employees charge their vehicle throughout the day. The company would be OK to offer a slow charge EVCP, as the typical charging time for a full charge would be 6 hours. If you are charging a vehicle overnight at home, then a slow charging unit would also be sufficient. In contrast, a department store, where most people spend on average 1½ hours, a fast (3 hour) EVCP would be totally acceptable.

These typical charge times are based on the time taken to fully recharge the vehicle, but often an electric vehicle driver will only require a partial charge to keep their vehicle “topped up”, if for example they have travelled from home to a fairly local location.

How long does it take to charge an electric vehicle?

Vehicle charging times vary according to three key factors:

  1. The battery - its capacity and the amount of existing charge it contains
  2. The charge point – its type and charging speed.
  3. The vehicle – not all electric vehicles will accept faster speeds of charging.

 Using a nominal vehicle battery capacity of 22kWh, the estimated charge times (rounded for simplicity) would be:

Charge Point Type

Charging Time (Hours)

Basic

9.5

Standard

6.0

Fast

3.0

Very Fast

1.0

Rapid

0.5

Please note that the ability to charge at ‘fast’, ‘very fast’ and ‘rapid’ rates is dependent on the vehicle, as not all vehicles can charge at this speed. For accurate timings for a specific make and model of electric vehicle, consult the vehicle manufacturer.

A rapid charge unit will generally charge an electric vehicle 80% within 20-30 minutes, but the last 20% will be at a much slower rate to conserve and protect the life expectancy of the battery.

How is the charging time calculated?

At present, there is still no official standard guidance on charging types and times, but for those who wish to understand how charging times are calculated, here is some basic electrical theory!

  • Power (Watts) = Current (Amps) x Voltage (V)
  • Charge Time (hours) = Battery Capacity (kWh) / Power (kW)

In a three-phase system the power is simply three times the single-phase power. In UK (and rest of Europe) the Voltage is the standard 230V, for either a domestic single-phase supply or the phased voltage of a commercial three-phase supply.

Using a nominal vehicle battery capacity of 22kWh, the estimated charge times (rounded for simplicity) would be:

Some electric vehicles can only accept 16 amp charge. So a ‘fast’ or ‘very fast’ charge using a 32 amp supply, or a ‘rapid’ charge using a 63 amp supply will still only deliver a 16 amp charge, if that is the maximum that the vehicle can accept. These vehicles will therefore only charge at a ‘very slow’ or ‘slow’ rate, depending on the type of charge point being used.
