EV Connectors and Cables: Type 2, CCS, CHAdeMO and Mode 3

Walk up to any public charge point in the UK and you will meet one of a small number of plugs. For home and slower charging, around 7kW, the connector is Type 2, which has been the standard for electric vehicles in the UK and Europe since the EU mandated a Type 2 socket on all plug-in cars from 2014¹. For rapid charging, the plug is almost always CCS, the Combined Charging System, which is the standard for rapid DC charging in the UK and Europe¹. A third connector, CHAdeMO, survives mainly on older Nissan Leaf models, and Tesla's own Type 2 variant appears on older Model S and Model X cars¹.

The cable you carry, and whether you need to carry one at all, follows from these names. Almost all electric cars come from the manufacturer with a cable that has a Type 2 connector on the charge point end, and most UK and European cars use a Type 2 to Type 2 connection for AC charging⁴. Rapid points are different: their cables are tethered, fixed to the unit, so nothing to carry. This page explains each connector, the charging modes behind them, what 3kW, 7kW and 22kW mean in hours, and how to check a car before spending money on a charger or cable.

Type 2: the standard plug for AC charging

Type 2, sometimes called Mennekes after its original maker, is the standard for EVs in the UK and Europe for home and public AC charging¹. Home and slower chargers, around 7kW, use Type 2 connectors, and the EU's 2014 mandate means it is the most common socket type in the UK². A typical council-run public network illustrates the mix you meet in practice: Anglesey's charge points offer Type 2 sockets at 22kW alongside CCS at 50kW and CHAdeMO at 50kW³.

Type 2 connectors typically support power levels from 3.7 to 7.4kW for home, workplace and on-street charging, rising to 22kW where the supply is three-phase, and less commonly 43kW¹. The connector itself is the same in all these cases; what changes is the power available behind the socket. That is why a car that charges at 7kW at home can charge faster at a three-phase public point, up to the car's own on-board charger limit.

For most modern EVs, a Type 2 to Type 2 cable is what connects the car to a public AC point¹. Almost all electric cars are able to charge on a Type 2 unit, and as the most common public charge point standard, nearly every car comes with a Type 2 cable from the factory⁴. Tesla's home and public AC chargers also use Type 2, so the same Type 2 to Type 2 cable works there too; Tesla Superchargers use tethered cables, so no additional cable is needed¹.

One older connector still appears occasionally: Type 1, used for AC charging on a few older EVs, notably older Nissan Leaf models¹. It is increasingly rare on UK roads, but if you buy a used EV it is worth knowing it exists. More detail on how Type 2 and CCS divide the work between them is at Type 2 vs CCS.

Fast DC plug types: CCS and CHAdeMO explained

CCS, the Combined Charging System, is the main connector type for higher-powered DC charging and the standard for rapid DC charging in the UK and Europe¹. Rapid chargers almost always use CCS plugs⁴. The connector is effectively a Type 2 plug with two extra DC pins added beneath, which is why a CCS car can still use Type 2 points for AC charging.

CHAdeMO is the other DC connector, and its role has narrowed. It supports rapid and ultra-rapid charging at power levels from 25kW up to 400kW, although the most common rating is 50kW, and it is primarily used for rapid DC charging on older Nissan Leaf models¹. On rapid chargers, DC charging works with CCS and CHAdeMO 50kW connectors, while AC rapid charging uses a Type 2 43kW connector; CHAdeMO is a 4-pin connector⁸. For the Nissan Leaf specifically, the CHAdeMO connector required for rapid charging is tethered to the charging unit, so a Leaf driver does not need to carry anything for rapid stops⁹.

The two DC standards are not interchangeable. Adapters between CCS and CHAdeMO do not exist, so a car fitted with one cannot use a rapid point fitted only with the other⁴. In practice this matters less than it once did, because the major rapid networks carry both: MFG EV Power, Osprey Charging and InstaVolt all provide charging with tethered devices via both CHAdeMO and CCS connectors¹⁰. Some drivers may still require a CHAdeMO or CCS charging adapter if the charging socket is not compatible with their EV at certain ultra-rapid points¹⁰.

Tesla's older Model S and Model X vehicles use a Tesla Type 2 connector for both AC and DC charging, which is physically compatible with standard Type 2 points for AC¹. Newer Tesla models sold in the UK use CCS for rapid charging, in line with the rest of the market. The comparison between the two DC standards is covered at CHAdeMO vs CCS, and the cars that still use CHAdeMO at which cars use CHAdeMO.

Socket or attached cable: the plug you will have on the go

Home charge points come in two forms. Home chargers are available either with a tethered Type 1 or Type 2 cable, which can be plugged straight into the car, or with a Type 2 socket for use with the vehicle's own charging cable⁶.

The choice has practical consequences. A tethered unit means nothing to carry between the car and the garage: you park, plug in and walk away, which is why tethered chargers are often described as the more convenient choice for home charging¹¹. The trade-off is that with a tethered home charger you are limited by the connector type and by the length of the cable, unless you pay to have replacements fitted; tethered units also take up more room and tend to be more expensive to purchase upfront¹⁰.

An untethered socket is future-proof in one specific sense: if the next car in the household has a different connector, you buy a new cable rather than a new charger. The downside is that the cable has to be carried in the car for public charging anyway, and you have to fetch it, uncoil it and lock it at home each time. Some untethered points also leave the socket exposed to the weather, though the units are designed for it.

For public rapid charging the question does not arise. With mode 4 charging, the DC rapid case, the charger always uses a tethered cable¹². The full comparison, including the security of the cable and what happens when you change cars, is at tethered vs untethered EV charger.

How charging works and the standards that govern it

The plugs described above sit on top of a set of international standards that define how charging equipment behaves. The series of standards for the design and performance requirements of EV conductive charging equipment is BS EN IEC 61851, and the connector definitions themselves come from the IEC 62196 family¹³. In everyday terms, these standards are what make a Type 2 cable from any maker work with a charge point from any other maker.

Charging is divided into modes. Mode 3 AC charging cables are the most common type of electric car charging cables in use, connecting an EV to a specialised charging station at home, at the office or in parking lots¹⁴. Mode 3 is what a home wallbox, a workplace charger and a public AC point all deliver. Mode 4 is DC charging, where the charger converts the power itself and always uses a tethered cable¹².

Below Mode 3 sit the slower modes. Mode 2 is charging from a standard household socket using a cable with built-in protection, the 13A three-pin route, and Mode 1 is a direct connection without any communication, which is not used for modern EVs. To achieve faster charging speeds, a dedicated EV charge point over a standard household socket is recommended¹⁵. The differences between the wallbox route and the three-pin route, including the safety case, are set out at can I charge an EV from a 3-pin socket.

The standards also cover the safety equipment inside the unit. Guidance on RCD protection for EV charging equipment sits within the IEC 61851 framework, and it is one reason a properly installed charge point is safer than a domestic socket, even though both deliver electricity¹³. The certification side is covered later on this page.

Charge speeds explained by power output

The number on a charger, 3kW, 7kW or 22kW, is the maximum power it can deliver, and the car's on-board charger caps what is actually used. A charger with a power rating of 3kW, 5kW or 7kW will generally take between six and 12 hours to charge a typical EV from 20 per cent to 80 per cent or above¹⁶. That range is wide because battery sizes differ, but it gives the order of magnitude: overnight, not minutes.

The Nissan Leaf is a useful worked example. On a standard 7kW AC home charger, a charging session takes approximately seven hours to go from 0 to 100 per cent¹⁷; Zapmap's model page for the Leaf gives 7.5 hours to 100 per cent at 7kW, and the two figures differ only in precision⁹. For the Leaf 40kWh version, a 7kW charger provides an 80 per cent charge in around 6 hours⁶. On a 50kW DC charger, the car takes approximately 43 minutes to go from 20 to 80 per cent, adding roughly 14 to 116 miles of range depending on the model¹⁷.

At the top of the home range, 22kW chargers are the most expensive and require a three-phase connection, which most UK homes do not have². Some units cover both cases: the EmonEVSE charger, for example, is rated at 7kW on a single-phase supply and 22kW on three-phase¹⁸. A Level 3 charger in the Cenex classification delivers 7kW AC, which is the rating most UK homes end up with¹⁹. The trade-offs are compared at 7kW vs 22kW home charger.

Two practical points affect real charge times. First, the car's own limit: a Leaf will never draw more than its on-board charger allows, whatever the point supplies. Second, sharing: some EV chargers split the power 50:50 between two vehicles, even if this is not the most efficient approach, so a rapid stop can be slower when the unit is busy¹⁷. Full charging-time tables are at EV charging speeds and times, and Leaf-specific figures at Nissan Leaf charging time.

Home charge point prices

A home charge point is the cheapest way to charge an EV, provided there is a driveway or garage for a dedicated charge point⁷. It typically costs between £500 and £1,200 to buy and install a home EV charger², and for the common 7kW unit specifically, the fully installed price is typically between £700 and £1,200⁶. Prices are installer-quoted and vary with the cable run, the consumer unit and any work needed to the supply.

Grants narrow the cost for some households. Landlords and flat tenants are eligible for a government grant of up to £350 for home EV chargers, which can reduce the installation cost to as low as £650²⁰. The grant schemes have been extended for a final year, with funding until 31 March 2027, so households planning an installation have a window rather than an open-ended entitlement. The details of who qualifies are at the Electric Vehicle Chargepoint Grant and the EV Chargepoint Grant for landlords.

The running-cost side matters more than the hardware over the car's life. Charging at home means buying electricity at domestic rates, usually on an EV tariff that cuts the overnight price, against public points that charge a premium per kWh. The sums are worked through at what does it cost to charge an electric car at home and home vs public EV charging costs. The VAT position also differs between home and public charging, which is explained at why public EV charging VAT is higher.

Siting, weatherproofing and built in safety measures

Charging equipment is designed to live outdoors. It is completely safe to charge an EV or PHEV in the rain, and the same equipment tolerates being taken through a car wash¹¹. The connectors and cables are sealed against water ingress, and the charging process includes continuous checks that stop the session if anything is wrong. Rain has no effect on charging speed; a slow session in wet weather has another cause, usually the car, the battery temperature or a shared unit¹⁷.

Independent certification backs this up. Charge points for home and commercial use are tested and certified for safety, security, quality and reliability, and the BSI Kitemark programme for EV chargers covers exactly those attributes²¹. The standardisation effort goes back further: European automobile manufacturers proposed a comprehensive set of common standards for EV charging covering all aspects including the method of communication between the vehicle and the power grid, the type of electricity supply and the differences between fast and slow charging systems²². That work is why a Type 2 cable works everywhere.

Where the unit goes is mostly a matter of cable reach and the supply. A wall-mounted unit by the parking space keeps the cable run short; a pedestal in a driveway does the same where the wall is far away. Most local authorities specify that households install a dedicated EV charger with protective earth neutral (PEN) fault protection, which is a feature of the unit rather than the location²³. The safety systems inside a charge point, including RCD protection, are covered at EV charge point safety, standards and certification and what RCD protection does an EV charge point need.

Planning permission and building rules

Installing a home charger is classified as development, so it is up to the householder to ensure the correct permissions are in place²⁴. The good news is that if the home has off-street parking, the installation of a domestic EV charger is likely to fall under permitted development rights, with no planning application required, provided it meets the criteria²⁵. Building regulations approval is always required when installing an EV home charger, and a competent, reputable installer should be used, with the installer notifying the local building control authority through the proper process²⁵.

Planning permission is usually required in a defined set of cases: on-street parking, conservation areas, listed buildings, areas where installation is restricted through article 4 directions, and where more than one upstand per parking space is wanted²⁴. The planning rules depend on whether the dwelling has off-street or on-street parking²⁸. Two further triggers come from Energy Saving Trust: permission is required if there is no off-street parking, and if the charger is installed less than two metres from the highway²³.

The size limits are precise. For a wall-mounted electrical charging outlet, planning permission is not required provided the outlet and its casing do not exceed 0.2 cubic metres, and provided it is not located on scheduled ancient monument land, though the exemption is narrower in conservation areas and Areas of Outstanding Natural Beauty²⁹. Households without off-street parking face a different route: a cross-pavement charging solution needs permission from the Highways Authority, and separate planning permission may be required for the pavement crossing itself, since it sits outside the curtilage of the building on the highway³⁰. The full rules, nation by nation, are at planning permission for a home EV charge point and building regulations approval.

In Northern Ireland, grant support exists specifically for households charging from the street: the Electric Vehicle Chargepoint Grant for households with on-street parking requires that the applicant has not already installed the chargepoint, owns or rents the residential property they live in, installs a non-temporary cross-pavement charging solution alongside the chargepoint, has no private and exclusive access to off-street parking, has adequate on-street parking, has permission from the local highways authority, and owns or is responsible for an eligible vehicle³¹. Applicants must provide evidence including local highways authority consent for the cross-pavement solution and a declaration that they will obtain the necessary planning permissions³². The scheme is explained at the Cross-Pavement Charging Grant.

Vehicle checks before choosing a cable or charger

The connector on the car is the fact that determines everything else, and it is checkable in seconds: open the flap and count the shape. Most UK and European EVs use a Type 2 to Type 2 charge connection, but it is important to check the specific vehicle¹¹. Almost all electric cars are able to charge on a Type 2 unit, and nearly all come from the manufacturer with a cable with a charger-side Type 2 connector⁴.

The used market is where surprises happen. A Type 1 socket on an older Leaf, a CHAdeMO-only rapid capability, or a Tesla Type 2 connector on an older Model S or Model X each change what cable or charger is needed¹.

A short checklist before spending money:

• Identify the car's AC socket: Type 2 is the norm; Type 1 appears on some older models¹.
• Identify the car's DC socket, if it has one: CCS is standard; CHAdeMO is on older Leafs; older Teslas use their Type 2 connector for DC¹.
• Check what cable came with the car: most supply a Type 2 to Type 2 cable⁴.
• Decide tethered or untethered for the home unit, knowing a tethered cable locks in the connector type¹⁰.
• Confirm the home supply: single-phase caps most homes at 7kW; 22kW needs three-phase².

The impact on your home energy self sufficiency

A home charge point with a Type 2 socket is one of the cleanest wins available for household energy independence. The car is fuelled from the house's own electricity supply rather than a forecourt, at the cheapest rate available to an EV owner⁷, and the household chooses the tariff, the timing and, with solar, even the source of the energy. A solar-aware charger can prioritise the household's own generation, which is covered at charging an EV from solar panels.

The dependencies that remain are worth naming. The charge point still draws from the grid, and the network operator must be told about the installation, as explained at telling the network operator about a home EV charger. Smart chargers connect to the manufacturer's cloud and app, which introduces a dependence on the company that made the unit, covered at EV charger apps, Wi-Fi, 4G and firmware and EV charger cybersecurity, data and remote control. The connector standards themselves are a form of dependence on international agreement, but a stable one: the Type 2 and CCS standards are mandated across the UK and Europe, so a cable bought today will fit the infrastructure built tomorrow².

The deeper independence question is whether the car can give back. Vehicle-to-grid and vehicle-to-home charging, where the car's battery supports the house, is the next step, and it is covered at vehicle-to-grid and vehicle-to-home. For most households today, the realistic position is simpler: a Type 2 charge point, a CCS car and an overnight tariff remove the petrol station from daily life, and leave the grid as a supplier of electricity rather than a controller of the household's mobility.
