EV Safety Standards

As EVs continue to grow in popularity around the world, it is essential that charging systems operate safely and reliably. When charging an electric vehicle, there is a large amount of current at high voltage (230V) carried in the charging cable from the power source to the EV. This AC is converted to a DC voltage to charge the EV batteries, and the DC voltage can be as high as 600V. Such high AC and DC voltages can give rise to insulation breakdown over time due to wear and tear and aging, etc. Insulation breakdown presents a risk of electric shock or electric faults, undermining safety.

It is of paramount importance to the EV industry that EVs are safe when it comes to charging. International standards bodies have considered the risks associated with EV charging and have introduced specific requirements to deal with these risks. These requirements cover Mode 2 and Mode 3 EV charging cables and equipment, and also installation rules in relation to EV charging.

IEC Safety Standards

IEC (The International Electrical Commission) is the world body dealing with international standards, and IEC has introduced specific requirements in relation to EV charging. The main International Standards produced to date are:

IEC60364-7-712-2017 Dealing with Installation Rules for EV Charging

Mode 2
Mode 2

IEC 62752 In-cable control and protection device for mode 2 charging of electric road vehicles (IC-CPD).

Mode 3
Mode 3

IEC 62955 Residual Direct Current Monitoring Device to be used for Mode 3 charging of Electric Vehicle.

IEC Requirements

Technical experts from Western Automation Emobility participated in the drafting of IEC62752 and IEC62955 and have detailed knowledge of these standards. As a result, all EV solutions designed and supplied by WA are guaranteed to comply with all of the requirements of IEC. Furthermore, WA has filed patents in relation to EV charging solutions, and can protect customers against possible infringement of third party patents.

In time, the above IEC standards will be adopted either completely or with some modifications by other standard bodies such as Cenelec and UL, and by national committees such as UL, BS and VDE, etc.
