What are the modes of charging IEC 61851?

Electric vehicles (EVs) are becoming increasingly popular due to their environmental benefits and the convenience they offer. However, one of the major challenges with EVs is the lack of standardization in charging. The International Electrotechnical Commission (IEC) has developed a standard called IEC 61851 to define various modes of charging that can be used to power up EVs. In this article, we will explore the modes of charging defined by IEC 61851 in detail.

Mode 1: Domestic Charging

Mode 1 is the most common mode of charging for EVs. It involves using a standard domestic socket to charge the vehicle. The key features of this mode include the use of a separate fuse to protect the vehicle and the user from electrical hazards, as well as the use of a thermal switch to limit the amount of power being charged.

Charging equipment and safeguard both the vehicle and the user during the charging process are essential for this mode. Additionally, IEC 61851-2 supports the use of different charging technologies, such as level 2 (240V) and DC fast charging.

Mode 2: Additional Safety Features

Mode 2 is an optional mode of charging for EVs that involves the use of additional safety features. This mode is designed to be used in charging stations that are not equipped with a grounding fault protection (GFC) device.

The key features of this mode include the use of a separate fuse to protect the vehicle and the user from electrical hazards, as well as the use of a thermal switch to limit the amount of power being charged. Additionally, IEC 61851-2 supports the use of different charging technologies, such as level 2 (240V) and DC fast charging.

Mode 3: Dedicated Charging

Mode 3 is an optional mode of charging for EVs that involves the use of dedicated charging equipment. This mode is designed to be used in charging stations that are equipped with a grounding fault protection (GFC) device.

The key features of this mode include the use of a separate fuse to protect the vehicle and the user from electrical hazards, as well as the use of a thermal switch to limit the amount of power being charged. Additionally, IEC 61851-2 supports the use of different charging technologies, such as level 2 (240V) and DC fast charging.

Conclusion

IEC 61851 is a standard that defines various modes of charging for EVs. These modes include domestic charging, additional safety features, and dedicated charging. By using these modes, EV owners can charge their vehicles more efficiently and safely. Additionally, IEC 61851-2 supports the use of different charging technologies, making it easier for manufacturers to offer a variety of EV charging options to their customers.
