Q. What are the different types of charging? (slow, fast and rapid)
There are 3 different types of charging; typically called 'slow', 'fast' and 'rapid' in the UK.
Slow charging occurs at 3kW, and is most common in UK homes. At 3kW, a full charge is likely to take 5-8 hours, so slow charging is perfect for overnight use.
Fast charging occurs at 7kW-22kW; a full charge at 7kW can typically take around 3-5 hours and at 22kW this could be reduced to as little as 2-3 hours. Charging above 7kW requires 'three phase' electricity which is not normally available in UK homes, but is often available elsewhere.
Rapid charging can fill a vehicle battery by 80% in as little as 20 minutes. Rapid chargers are most commonly found at motorway services and at electric forecourts, where charging occurs at between 50kW and 350kW.
It is important to note that these figures are only a guide, charging speed depends not only on the charger, but also the capability of the vehicle and the size of the vehicle's battery.
