Electric vehicle charging connectors: which one to choose in?

Today there is 5 main standards, which are actively used by manufacturers:

• 🔌 Type 1 (SAE J1772) - obsolete standard for AC-charging, popular in the USA and Japan.
• 🔌 Type 2 (Mennekes) - European standard for AC-charging, supports up to 43 kW.
• ⚡ CCS (Combined Charging System) - expansion Type 1/2 for DC-charging, speed up to 350+ kW.
• ⚡ CHAdeMO - Japanese standard for DC-charging, up to 400 kW (used in Nissan Leaf, Mitsubishi Outlander PHEV).
• ⚡ NACS (Tesla Supercharger) - proprietary-standard Tesla, from 2026 open to other brands.

The key difference between them is not only the shape of the connector, but also communication protocol between the car and the charging station. For example, CCS and CHAdeMO use different authentication and power control methods, making them incompatible without adapters.

2. Type 1 (SAE J1772): an aging but still living standard

Type 1 is the first mass-produced connector for electric vehicles, developed in the USA in 2009. It only supports AC- charging power up to 7.4 kW (single-phase network) and up to 19.2 kW (three-phase, but such stations are rare). The connector has 5 pins: two for power, two for data and one for ground.

Main disadvantage Type 1 - lack of support DC-charging. This means that for quick charging on the highway, owners of cars with such a connector (Nissan Leaf first generation Chevrolet Volt, Mitsubishi i-MiEV) an adapter is required for CHAdeMO or CCS. In Europe Type 1 practically superseded Type 2, but it is still found in the USA and Japan.

⚠️ Attention: If your electric vehicle is only equipped Type 1Please check availability before purchasing DC-adapter included. For example, Nissan Leaf 2018–2022 not supported as standard CCS, only CHAdeMO.

Benefits Type 1:

• 🔹 Simplicity of design and low cost of charging cables.
• 🔹 Compatible with most older charging stations in the US.
• 🔹 Compact size of the connector (convenient for daily use).

Disadvantages:

• ❌ Low maximum power (up to 19.2 kW in theory, but in practice rarely higher than 7.4 kW).
• ❌ Lack of support DC-charging without adapter.
• ❌ In Europe it is being forced out Type 2, making it difficult to find charging stations.

3. Type 2 (Mennekes): European standard with prospects

Type 2 (or Mennekes named after the developer company) is the main connector for AC-charging in Europe, supported by all modern electric vehicles, from Renault Zoe up to Porsche Taycan. It allows you to charge up to 43 kW (three-phase network) and is mandatory for new models in the EU from 2018.

Connector Type 2 has 7 contacts: three for phases, one for neutral, one for ground and two for charging control. Thanks to this, it supports both single-phase (up to 7.4 kW) and three-phase networks (up to 22–43 kW). It is important that Type 2 often used in combination with CCS for DC-charging (more on this in the next section).

Benefits Type 2:

• 🔹 High maximum power (up to 43 kW) - enough to fully charge most electric vehicles in 4-6 hours.
• 🔹 Widespread in Europe (more than 80% of public AC-stations).
• 🔹 Compatible with CCS Combo 2 for DC-charging.
• 🔹 Feature support Plug & Charge (automatic authentication without cards).

Disadvantages:

• ❌ More bulky connector compared to Type 1.
• ❌ It is less common in the USA and Asia, which can create problems when traveling.

4. CCS (Combined Charging System): a universal solution for fast charging

CCS (Combined Charging System) is an extension of the standards Type 1 and Type 2, adding support DC-charging. There are two options:

• 🔌 CCS Combo 1 - based on Type 1, used in the USA and Asia (max. power up to 350 kW).
• 🔌 CCS Combo 2 - based on Type 2, standard in Europe (max. power up to 350+ kW).

CCS adds two additional contacts for DC- charging, which allows you to use one connector for both types of current. This solution is supported by most modern electric vehicles, including Volkswagen ID.4, Audi e-tron, Ford Mustang Mach-E and Hyundai IONIQ 5. The latter, by the way, can be charged at CCS- stations with power up to 238 kW, restoring 80% charge in 18 minutes.

Benefits CCS:

• 🔹 Versatility: one connector for AC and DC-charging.
• 🔹 High charging speed (up to 350 kW at new stations).
• 🔹 Supported by most manufacturers (except Tesla and some Japanese models).

⚠️ Attention: Not all cars with CCS support a maximum power of 350 kW. For example, BMW i3 limited to 50 kW, and Kia EV6 - 240 kW. Always check your model's specifications!

In 2026 CCS Combo 2 has become a mandatory standard for new electric vehicles in the EU, which means a gradual phase-out CHAdeMO and Type 1. This is important to consider when buying a used electric car: models older than 2020 may have outdated connectors.

5. CHAdeMO: Japanese standard at the end of an era

CHAdeMO (CHArge de MOve, “charging for movement”) is the standard DC-charger developed in Japan in 2010. It supports power up to 400 kW, but in practice most stations are limited 50–100 kW. CHAdeMO used in the first mass-produced electric vehicles, such as Nissan Leaf (until 2022), Mitsubishi Outlander PHEV and Kia Soul EV.

Main problem CHAdeMO - lack of support AC-charging. This means that vehicles with this connector require a separate port for Type 1/2, which complicates the design and increases the cost. In addition, since 2020, most manufacturers (except Japanese) have abandoned CHAdeMO in favor CCS.

Benefits CHAdeMO:

• 🔹 High reliability (designed for harsh operating conditions).
• 🔹 Compatible with old Japanese electric cars.
• 🔹Support V2G (Vehicle-to-Grid, feed back energy into the grid).

Disadvantages:

• ❌Outdated infrastructure (new stations CHAdeMO almost never installed).
• ❌ Requires a separate connector for AC-charging.
• ❌ Slower CCS at modern stations (max. 100–150 kW versus 350 kW).

6. NACS (Tesla Supercharger): revolution or temporary solution?

NACS (North American Charging Standard) is a proprietary connector developed by Tesla for their superchargers. Until 2022 it was a closed standard, but in November 2022 Tesla opened the specifications to other manufacturers. From 2026 NACS begins to be implemented in new models Ford, GM, Rivian and other brands.

NACS supports both AC- (up to 19.2 kW), and DC-charging (up to 250 kW at current stations, in the future up to 1 MW). Its main advantage is its compactness and simplicity of design (only 5 contacts versus 7 Type 2). However in Europe NACS is not yet certified and its future is unclear.

Benefits NACS:

• 🔹 Compact and lightweight connector.
• 🔹 Network access Tesla Supercharger (more than 40,000 stations worldwide).
• 🔹Supports high powers (up to 250 kW).

Disadvantages:

• ❌ Limited compatibility (currently only in the US and Canada).
• ❌ Requires an adapter for charging at stations CCS or Type 2.
• ❌ Not certified in Europe (possible problems with homologation).

In 2026 Tesla started supplying adapters NACS → CCS for owners of their cars in Europe, but their cost (~200 euros) and limited availability remain a problem. If you are planning a purchase Tesla in EU, please make sure your model supports CCS natively (for example, Model 3 and Model Y 2023+).

7. Which connector should I choose in 2026?

The choice of charging connector depends on three factors: region, car models and typical use cases. Here are some quick recommendations:

• 🌍 Europe: Optimal choice - Type 2 for AC-charging and CCS Combo 2 for DC. This guarantees compatibility with 99% of stations.
• 🇺🇸 USA: In 2026, priority will be given to NACS (for new models) or CCS Combo 1 (for old ones). Type 1 outdated.
• 🇯🇵 Japan: CHAdeMO and Type 1 still found, but new cars are switching to CCS.

If you buy used electric car, please note:

• 🔋 Year of manufacture: models before 2018 are often equipped Type 1 or CHAdeMO.
• 🔌 Availability of adapters included (for example, CHAdeMO → CCS).
• 🗺️ Prevalence of infrastructure in your region (check on PlugShare or ChargeMap).

For new cars in 2026, the best choice is models with CCS Combo 2 (Europe) or NACS (USA). If you are considering Tesla, check if the model supports CCS natively or an adapter is required.

8. The future of charging connectors: what awaits us?

The charging connector market is in a transition period. Key trends for 2026–2026:

• 🔹 Unification of standards: CCS Combo 2 will become mandatory in the EU, and NACS - in the USA. CHAdeMO and Type 1 will finally become a thing of the past.
• 🔹 Power increase: New stations CCS will support until 500 kW, reducing charging time to 10–15 minutes.
• 🔹 Wireless charging: Inductive charging technologies (up to 11 kW) will begin to be implemented in public spaces (parking lots, hotels).
• 🔹 V2G (Vehicle-to-Grid): The connectors will support the reverse supply of energy from the car to the network (relevant for CHAdeMO and new versions CCS).

In 2026 Tesla announced the connector NACS v3 supporting up to 1 MW, which could become the new standard for electric trucks and buses. However, its introduction into passenger cars is unlikely until 2026–2027.

For electric vehicle owners this means:

• 🔹 When buying a car today, choose models with CCS Combo 2 (Europe) or NACS (USA).
• 🔹 If your car is equipped CHAdeMO or Type 1, stock up on adapters or plan to replace your machine in the next 3-5 years.
• 🔹 Keep an eye on infrastructure updates in your region - old stations may close.
