Electric cars need like any vehicle a fuel to power it and they require fuel of a very different kind to that of Gas powered cars. Electric cars hold within them battery cells which, when charged, can produce power for the electric motors. This energy has the ability to take the vehicle long distances.
Electric car chargers come in all shapes and sizes. They have different levels of charge and also depending on the type of electricity connection can produce different amounts of energy. The most environmentally friendly type of generating electricity is producing renewable energy through wind, sun or water to charge the batteries of the electric cars.
Types of Car 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. Note that 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 (depending a battery capacity). Tesla Superchargers are also Rapid DC and charge at around 120 kW. Rapid AC devices use a tethered Type 2 connector, and Rapid DC chargers are fitted with a CCS, CHAdeMO or Tesla Type 2.
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. EVs charge on slow devices using a cable which connects the vehicle to a 3-pin or Type 2 socket.
