Can you connect 2 Type 2 cables together?

Connecting electric vehicles to charging stations is an essential part of the EV driving experience. One common question that arises is whether it is possible to connect two Type 2 cables together for a longer reach or more flexibility. In this article, we will explore the technical aspects of connecting Type 2 cables and discuss the considerations and limitations involved.

Understanding Type 2 cables

Type 2 cables, also known as Mennekes cables, are widely used in Europe for charging electric vehicles. They have a seven-pin design and utilize the IEC 62196-2 standard. Type 2 cables provide both power and communication between the vehicle and the charging station, allowing for safe and efficient charging.

It is worth noting that Type 2 cables come in various lengths, typically ranging from 3 to 7 meters. However, there might be situations where a longer cable length is required, leading to the thought of connecting two cables together.

The limitations of connecting Type 2 cables

While it might seem feasible to connect two Type 2 cables together using adapters or couplers, this practice is not recommended. Connecting cables introduces additional resistance, which can affect the flow of electricity and potentially lead to overheating or even a fire hazard.

The IEC 62196-2 standard specifies the use of a single cable for each connection, ensuring proper electrical performance and safety. Any modification or extension to this standard is strongly discouraged by manufacturers and regulatory bodies.

Moreover, connecting two Type 2 cables may compromise the protective earth (PE) conductor, which is designed to ensure safety against electric shock. Altering the cable configuration can result in the loss of this protective function, posing a significant risk to both the vehicle and the user.

Alternative solutions for longer reach

If a longer cable length is necessary, alternative solutions can be pursued. One option is to use a Type 2 extension cable specifically designed and certified for this purpose. These extension cables are manufactured following the same standards and guidelines as regular Type 2 cables, which ensures compatibility and safety.

Another approach is to install additional charging stations strategically in areas where longer cable lengths are required. This solution eliminates the need to connect multiple cables together and preserves the integrity of the Type 2 cable system.

In conclusion, connecting two Type 2 cables together is not recommended due to the potential risks involved. It is advised to explore other alternatives, such as using certified extension cables or installing additional charging stations, to achieve a longer reach without compromising safety and performance.
