Can you change a Type 1 charger to Type 2?

In recent years, electric vehicles (EVs) have gained significant popularity as an environmentally friendly alternative to traditional gasoline-powered cars. With this increase in EV adoption, the need for efficient and versatile charging solutions has become more important than ever. One common topic of discussion among EV owners is whether it is possible to convert a Type 1 charger to a Type 2. In this article, we will explore the technical aspects of this conversion and shed some light on the possibilities and limitations.

Understanding Type 1 and Type 2 Chargers:

Before diving into the conversion process, it's essential to understand the key differences between Type 1 and Type 2 chargers. Type 1 chargers, also known as SAE J1772 connectors, are predominantly used in North America and Japan. They provide charging capabilities at a maximum power rating of 7.4 kW, making them suitable for most residential and public charging stations.

Type 2 chargers, on the other hand, are widely adopted in Europe and offer greater flexibility. Based on the IEC 62196-2 standard, Type 2 chargers can support charging power ratings up to 22 kW or even higher, depending on specific models. This makes them compatible with various EVs, including those with larger battery capacities that require faster charging times.

The Conversion Process:

Converting a Type 1 charger to Type 2 involves several technical considerations. Firstly, the physical connector types differ between these two charger types. Type 1 chargers use a 5-pin connection, while Type 2 employs a 7-pin connection. This means that simply swapping the connector won't be enough to enable the conversion.

Another important aspect is the communication protocol used during the charging process. Type 1 chargers generally utilize the J1772 protocol, whereas Type 2 chargers employ a combination of IEC 62196-2 and Mode 3 protocols. Adapting the communication protocol to enable seamless charging with different EVs poses additional challenges in terms of software compatibility and fine-tuning.

Limitations and Considerations:

While it may be technically feasible to convert a Type 1 charger to Type 2, there are some limitations and considerations to keep in mind. Firstly, altering the charger's hardware and electrical components might void any warranties or certifications associated with it. It is essential to check with the manufacturer or consult a certified technician before making any modifications.

Furthermore, even if the physical conversion is successful, there might still be compatibility issues with certain EV models. Some vehicles rely on specific features available only in Type 2 chargers, such as bidirectional charging or vehicle-to-grid integration. Converting a Type 1 charger might not provide these advanced functionalities.

In conclusion, while it might seem enticing to convert a Type 1 charger to Type 2 for the added versatility and charging capabilities, it is crucial to carefully assess the technical feasibility and implications. Considering the potential warranty concerns and limitations in compatibility, it is advisable to explore alternative options, such as purchasing a separate Type 2 charger or utilizing adapters when needed.
