The electric vehicle (EV) revolution is sweeping the globe, and Malaysia is no exception. As the country embraces sustainable transportation, it’s crucial to understand the intricate regulations governing the heart of EVs – their connectors. These connectors play a pivotal role in ensuring safety, compatibility, and seamless charging experiences for EV users across Malaysia.

Understanding EV Connectors

EV connectors serve as the vital link between the charging station and the vehicle. They facilitate the transfer of energy from the grid to the EV’s battery, and they come in various shapes, sizes, and technical specifications. In Malaysia, the regulatory landscape ensures that these connectors meet stringent safety and compatibility standards.

Documentation and Standards

To ensure uniformity and safety in the EV charging ecosystem, Malaysia has adopted international standards for EV connectors. One of the most recognized standards is the International Electrotechnical Commission (IEC) 62196 standard, which outlines the requirements for EV connectors and charging systems. Malaysia’s adoption of such standards demonstrates its commitment to aligning with global best practices.

Malaysian Standards for EV Connectors

The Malaysian Energy Commission (Suruhanjaya Tenaga) plays a pivotal role in regulating the EV charging infrastructure. It has defined specific standards and guidelines for EV connectors to ensure they comply with safety, quality, and compatibility requirements. This includes factors such as voltage ratings, current ratings, mechanical specifications, and thermal performance.

Connector Types

IEC Type 2

Type : Combo CCS Type 2 (DC Charging)
Voltage (V) : 230 V ac / 400 V ac
Current (A) : Up to 52 A ac
Power (kW) : Up to 22 kW

CHAdeMO (DC Charging)

Type : CHAdeMO (DC Charging)
Voltage (V) : Up to 1000 V
Current (A) : Up to 400 A
Power (kW) : Up to 400 kW

Ensuring Compatibility

One of the critical factors in the success of EV adoption is ensuring compatibility between connectors and charging stations. Malaysia has taken steps to ensure that connectors used in the country are compatible with a variety of EV models and charging infrastructure. This compatibility not only streamlines the charging process for users but also encourages the growth of EV charging networks.

a) For mode 3 charging, a dedicated EVCS and a charging cable assembly shall be employed. The control pilot cable of the charging cable assembly allows communication between the EVCS and the on-board charger of an EV to perform functions including verification of connection with the EV, continuous checking of protective earth conductor integrity, energization and de-energization of the supply and selection of charging rate.
b) Dedicated charging plug, socket and coupler are required for Mode 3 charging, which are specially designed for EV charging.
c) Subject to the power rating of the on-board charger of an electric vehicle, Mode 3 charging can deliver a higher charging current (e.g. 230V/32A, 400V/32A, 400V/63A) and hence a shorter charging time.
d) Selection of EVCS shall depend on the charging protocol of the EV and on advice of the EV manufacturer

Mode 4 charging employs the principle of using an off-board charger to deliver a DC current directly to the battery bypassing the on-board charger. DC quick charging can charge up an EV in a relatively short
time as a substantially higher electrical power ranging from 20kW and above.

Consumer Education

In tandem with regulations, raising awareness among consumers about the importance of using certified and compatible connectors is crucial. Educating EV owners about the significance of using approved connectors can prevent safety risks and ensure a reliable charging experience.

For Mode 2 and 3, only Type 2 connector is allowed to use in EVCS because it has an inbuilt locking mechanism (safety purpose) and can carry single phase and three phase. Type 1 connector is not permitted because it does not have a locking mechanism and can carry single phase.

For Mode 4, CCS Type 2 and CHAdeMO connector is allowed to use in EVCS.

As Malaysia accelerates its transition towards sustainable transportation, the regulatory framework governing EV connectors plays a pivotal role in ensuring safe, efficient, and reliable charging infrastructure. The adherence to international standards, the type approval process, and the emphasis on compatibility collectively contribute to the growth of a robust EV ecosystem in the country. By navigating these regulations and standards, Malaysia is paving the way for a greener and more sustainable transportation future.
