There may be occasions when it is not possible to use a charging station: It is prone to mechanical and UV damage and is not recommended for use outdoors or below 5☌. Use PVC or blue ‘arctic’ flex, which despite frequent claims that it is ‘heavy duty’, the cable is far from it.This principle is the same for electrical cables. If you want high pressure at the end of your 10m garden, you’re not going to achieve it if you use a hosepipe the size of a drinking straw! The longer the distance, the larger diameter you need to sustain the same flow. Manufactured from cable which is not sufficiently large in diameter (normally 1mmsq or 1.25mmsq) to handle the relatively high sustained 10A current required.
Also, most extension leads available online and in DIY stores are: This is likely to be because when using domestic sockets there is no guarantee of the safety of the supply, including the appropriate RCD and PEN fault protection/earth rod protection which is required for dedicated EV sockets. In addition, some manufacturers recommend that extension leads are not used to charge EVs. The question of whether an extension lead should be used, and if so which type is best, is probably one of the most hotly debated issues on on-line forums. Often the lead supplied with a granny charger is not long enough to reach a socket. Can I use an extension lead with a granny charger? When ordering a granny charger it is important to correctly identify charging connector fitted to the EV using the diagram above. It enables single and three phase charging at 3.7kW-7.4kW AC. It was adopted as the EU standard for EVs in 2014 and is therefore the most common EV connector in the UK. Type 2 - Designed by the German manufacturer Mennekes, the connector has 7 pins.
It allows single phase charging at 3.7kW-7.4kW AC. It was predominantly used on vehicles from Asia, and is mainly found on older EVs within the UK e.g. Type 1 - Designed by the Japanese manufacturer Yazaki, the connector has 5 pins. Within the UK, connectors will be either IEC 62196 type 1 (left) or type 2 (right). There are a number of international standards for EV charging sockets. What's the difference between a type 1 and type 2 connector? If your car does not have a granny charger, we supply a range of great units here. We recommend checking the tightness of the fuse clips in the plug every 6 months or if the plug appears warm using this guide, to reduce the chance of overheating occurring. This is because whilst a UK 13A plug can supply 13A for short periods of time, it may overheat if that amount of current is drawn for longer periods of time. In the UK the charger is limited to draw no more than 10A (2.3kW). The connector will either be type 1 or type 2 (see section below for details). The granny charger consists of a 13A UK plug, a box containing the charger and a socket which connects to the EV. Rather confusingly it is commonly referred to as a 'granny charger', as it is a lead to use when visiting relatives such as your granny!

Most electric vehicles (EVs) are supplied with a portable domestic charger designed to charge the vehicle when access to a charging point is not possible. Most EV manufacturers recommend that a granny charger is not used as the sole means of charging. When not at home, it is best to use a public charging point. This ensures that the supply used has been tested to be safe and will achieve a faster charging time. When purchasing an EV, we would always recommend that you get a professionally installed charging unit outside of your home. What are the advantages of using a professionally installed charger?
