Adapting to Japan's Connectors for AC and DC Charging in Malaysia & South East Asia

As electric vehicles (EVs) gain traction in Southeast Asia, understanding the intricacies of charging connectors becomes paramount for enthusiasts, especially when importing cars from Japan. While Southeast Asian countries predominantly use the Type 2 connector for AC charging, Japanese EVs often come equipped with Type 1 connectors. Additionally, navigating the DC charging landscape involves using a CCS2 to CHAdeMO adaptor, with certain limitations on charging capacity. This article aims to shed light on these differences, providing essential information for a smooth EV charging experience.

Japan's Type 1 Connector for AC Charging

In Japan, the Type 1 connector (J1772) is the standard for AC charging. When Southeast Asian EV owners acquire Japanese electric vehicles, the discrepancy in charging connectors becomes evident. To overcome this challenge, a Type 2 to Type 1 adaptor proves indispensable. This adaptor ensures seamless compatibility with the widely-used Type 2 charging infrastructure in Southeast Asia, allowing EV owners to charge effortlessly at home, in public spaces, and at work.

Understanding the Need for Adaptors for Japan's Connectorc

The necessity for adaptors stems from the regional variations in charging connectors. With Southeast Asia predominantly using Type 2 connectors, EV owners must be aware of the differences when importing Japanese vehicles with Type 1 connectors. Opting for a Type 2 to Type 1 adaptor is a pragmatic solution, enabling a hassle-free charging experience without the need for extensive modifications to the vehicle's charging port.

DC Charging and the CCS2 to CHAdeMO Adaptor

For EV owners looking to utilize public DC charging stations in Southeast Asia, a CCS2 to CHAdeMO adaptor is essential. This adaptor facilitates communication between the vehicle's CHAdeMO port and the CCS2 charging station, ensuring compatibility. However, it's crucial to note that the maximum charging capacity for many Japanese specification vehicles is limited to 62.5kW.

Understanding the 62.5kW Limitation

Despite the availability of higher-capacity DC charging stations, certain Japanese EVs are restricted by their specifications to a maximum charging capacity of 62.5kW. This limitation is essential to consider when planning charging sessions, as it affects the charging speed and overall efficiency. EV owners should consult their vehicle's manual or the manufacturer to determine the specific charging capabilities of their model.


In navigating the electric vehicle charging landscape in Southeast Asia, awareness of charging connector differences and the need for adaptors is crucial. Whether it's bridging the gap between Type 1 and Type 2 connectors for AC charging or utilizing a CCS2 to CHAdeMO adaptor for DC charging, EV enthusiasts can optimize their charging experience with the right knowledge. By understanding these nuances, Southeast Asian EV owners can confidently embrace electric mobility and contribute to the sustainable future of transportation in the region.
