The standard “EN IEC 61851-1 Electric vehicle conductive charging system - Part 1: General”, which is based on a European standard and subsequently published by the International Electrotechnical Commission (IEC), describes a procedure for electric vehicle (EV) power supply equipment for charging electric road vehicles with a rated supply voltage of up to 1000 Volts alternating current or 1500 Volts direct current and a rated output voltage of up to 1000 Volts alternating current or 1500 Volts direct current.
Electric vehicles (EV) encompass all on-road vehicles, including plug-in hybrid on-road vehicles, that derive all or part of their energy from on-board rechargeable energy storage systems.
Matters addressed in this standard include:
The latest update of this standard has brought significant technical changes. For example, all requirements covered by the IEC 61851-22 standard have been moved to this standard. Furthermore, all requirements related to electromagnetic compatibility (EMC) have been removed from the text and are expected to be part of the future version of the 61851-21-2 standard. This standard also includes new requirements regarding the protection of the cable.
The electric vehicle charging infrastructure is classified as conductive and inductive charging. While conductive charging infrastructures are well developed, inductive charging infrastructures are still a hot topic for researchers. Conductive charging involves direct metal-to-metal contact between the electric grid and the electric vehicle to transfer power to the electric vehicle. This charging method is highly efficient and robust. Conductive charging infrastructures are classified as in-vehicle charging infrastructures and off-vehicle charging infrastructures. Off-vehicle charging infrastructures are designed for fast charging of electric vehicles. In off-vehicle charging infrastructures, chargers are usually installed in parking areas of shopping malls, hospitals, universities, or on highways. In general, electric vehicles use the conductive charging method.
The EN IEC 61851-1 standard is an international standard that specifies general requirements and test methods for electric vehicle charging systems. This standard is part of a series of standards developed by the International Electrotechnical Commission (IEC) to ensure interoperability and safety in electric vehicle charging infrastructure. This standard defines the essential requirements for conductive charging systems and covers aspects such as electrical safety and communication between the electric vehicle and the charging equipment. It also covers the compatibility of the different components in the charging system.
This standard creates a framework for various charging modes, such as Mode 1, Mode 2, Mode 3, and Mode 4, each specifying different levels of charging power and safety features:
In short, the IEC 61851-1 standard for electric vehicles provides a standard framework for charging electric vehicles, ensuring compatibility and safety across different manufacturers and charging infrastructure providers. The choice of mode depends on factors such as the existing infrastructure, the desired charging speed and safety requirements.
