New Energy Vehicles' Mode 2 EV Charging

With the popularity of new energy vehicles, Mode 2 EV Charging has become a common choice for daily charging. Mode 2 charging standard provides a convenient charging solution for electric vehicles, especially in home environments. This article will introduce the definition, applicability, and safety aspects of Mode 2 EV Charging to help car owners better understand and use this charging mode.

What is Mode 2 EV Charging?

Mode 2 EV Charging refers to a method of charging electric vehicles using a standard AC power source. On the power supply side, mode 2 charging requires the use of a live wire, neutral wire, and ground protection conductor, along with an in-cable control and protection device (IC-CPD) installed on the charging cable. This design ensures the safety and effectiveness of the charging process.

Mode 2 EV Charging includes a household plug, a charging gun, an online control and protection device (IC-CPD), and wires. The household plug typically has a specification of 220V/10A, which allows Mode 2 EV Charging to be conducted using ordinary household sockets. The charging gun ensures compatibility with electric vehicles.IC-CPD integrates power supply control, leakage protection, and charging status display functions, enhancing the safety and reliability of the charging process.

Mode 2 EV Charging Applicability and Power

Mode 2 EV Charging has a wide range of applicability. Wherever there is a household socket, this charging method can be used. It is suitable for environments with well-grounded sockets and can be conducted using ordinary household sockets. However, for safety reasons, it is not recommended to use old and worn-out sockets and to avoid using extension cords, as they may pose safety risks.

Mode 2 EV Charging typically has a charging power of 1.76kW ( 220V/10A) or 2.86kW( 220V/16A). The charging time varies depending on the battery capacity of the electric vehicle and the charging power. For example, it takes about 6.8 hours to fully charge a Roewe eRX5 PHEV using a 220V/10A charging line, whereas it takes 48.3 hours to fully charge a Tesla Model S BEV. This demonstrates the differences in charging time.

Mode 2 EV Charging Safety

When using Mode 2 EV Charging, safety is an important consideration. Due to the longer charging time, household sockets and charging lines may generate considerable heat. Therefore, households are usually equipped with temperature sensors to monitor the heating situation. If necessary, they will reduce the power or even stop charging to prevent safety accidents.

Additionally, Mode 2 EV Charging power has reached the maximum load capacity of household circuits and thus cannot be further increased. Although its power is lower compared to AC charging piles' 7.2kW and DC charging piles'  50kW, the convenience of  Mode 2 EV Charging makes it a standard charging device for new energy vehicles. Especially in hotels, rural areas, and other places without professional charging piles, Mode 2 EV Charging provides great convenience.

Mode 2 EV Charging, as a home charging solution, has become a standard charging device for new energy vehicles thanks to its wide applicability and relatively simple usage. Understanding the basic concepts, range of application, and safety measures of Mode 2 EV Charging helps car owners make more informed choices in daily use, ensuring efficient and safe charging processes.
