Understanding Electric Car Charging Cables

Not All EV Charging Cables Are Created Equal, But The EV Industry Is Moving Towards Greater Harmonization For Charging Protocol


I suspect, by now you have seen a few EV charge points in your city or neighbourhood, with zero-emission or ultra-low-emission vehicles (ULEVs) charging.  Some of you may already own an EV and have become experts in charging at home or at public EV charge points, to include workplace charging.  

However, for those of you, still trying to understand electric car charging and in particular, the cable types & connectors, this is a simple guide.  I would also recommend you read the following articles on the e-zoomed Electric Living Blog:


EV Charging Cables: The Basics


  • When do you need an electric car charging cable? Quite simply when you need to charge your EV, either at home or at a public charge point.  If your home charge point has a tethered cable, then you will not need to use another cable for charging at home.  However, you will still need a cable in your car for charging at a public charging point.  We recommend you always carry one.  For avoidance of doubt, all types of electric cars will require a charging cable to charge, to include, plug-in hybrid electric vehicle (PHEVs) and battery-electric-vehicles (BEVs).
  • It may seem ‘silly’ but choice of colour is also important.  For some reason, the EV community does not discuss this much.  No I am not talking about buying a cable that matches your wardrobe or car colour.  In general, the majority of cables currently used by electric car drivers are black in colour.  No doubt, black is smart, but I fear I am rather practical.  I would recommend buying  brightly coloured cables instead.  As you are aware, when charging at public points, to include on-street charging, the visibility of the cable will avoid any potential public liability issues, like an individual tripping over the cable. In particular, when charging during low light and night conditions.  We at e-zoomed can help you buy a brightly coloured EV charging cable.  Just follow this link to the e-zoomed store to buy either a bright blue or bright green charging cable

  • As is the case with any new technology, the EV industry has yet to harmonize charging cable protocols, hence the reason why different ‘types’ exist.  However, there is good reason to cheer, as the majority of new EVs are moving to Type 2.  Also, most public charging points and non-tethered home chargers have a Type 2 socket. The Type 1 plug allows for charging up to 7.4 kW. The Type 2 plug can charge up to 22 kW and even higher. The other plug types include, Combined Charging Systems (CCS)and CHAdeMO (more on these in another article).

  • Your electric vehicle will have either a Type 1 or Type 2 car inlet socket. Type 1 inlet is the American and Japanese standard (J1772). Type 2 inlet is the standard in Europe (IEC 62196).  Both have pins to carry power, a safety ground and communication.

  • Therefore the EV charging cable needs to ‘fit’ the vehicle socket.  If confused just check the EV manual for the ‘Type’ of charging cable required.

  • EV cables come in different ‘current ratings’, usually a 16 amp or 32 amp.  We recommend buying a 32 amp cable if suitable for your needs. Older EVs are fitted with a 3.6 kW onboard charger as standard that needs a 16 amp EV cable. However, newer electric cars have a 7kW charging capability that requires a 32 amp cable. Also, EV cables are either single phase or 3 phase.  So before you splash out on a 32 amp cable, make certain your EV is capable of taking advantage!
