Benefits of Electric Vehicle

Electric vehicles offer a number of benefits over conventional petrol or diesel models. Lower fuel costs & reduced maintenance bills are just some of the ways that running costs are reduced, while environmental impacts are also significantly reduced. The ‘EV benefits’ section explores the benefits offered by switching to an EV.

Types of EV Chargers

There are three main types of EV charging – rapid, fast, and slow. These represent the power outputs, and therefore charging speeds, available to charge an EV (Electric Vehicle). The power is measured in kilowatts (kW).

Rapid chargers are one of two types – AC or DC [Alternating or Direct Current]. Current Rapid AC chargers are rated at 43 kW, while most Rapid DC units are at least 50 kW. Both will charge the majority of EVs to 80% in around 30-60 minutes (depends upon the battery capacity). Rapid AC devices use a tethered Type 2 connector, and Rapid DC chargers are fitted with a CCS, CHAdeMO or GB/T.

Fast chargers include those which provide power from 7 kW to 22 kW, which typically fully charge an EV in 3-4 hours. Common fast connectors are a tethered Type 1 or a Type 2 socket (via a connector cable supplied with the vehicle).

Slow units (up to 3 kW) are best used for overnight charging and usually take between 6 and 12 hours for a pure-EV, or 2-4 hours for a PHEV (Plug-in Hybrid EV). EVs charge on slow devices using a cable which connects the vehicle to a 3-pin or Type 2 socket.
