Ratio Electric-Ahead in E-mobility

Matching the EV Standards 19 IEC 61851 STANDARD The IEC 61851 standard describes 4 charge modes: I Mode 1: max. 16A AC 230/400V I Mode 2: max. 32A AC 230/400V I Mode 3: max. 63A AC 230/400V I Mode 4: max. 400A DC 1000V For charging at home or at work mode 2 and mode 3 are most common. Mode 2 uses a standard domestic or industrial outlet. The charge cable must include an In Cable Control and Protection Device(IC-CPD). Mode 3 uses a dedicated EV outlet. The car type defines the type of plug and maximum charging current. Check with the manufacturer of the car for this information. All modes, except mode 1, require communication between vehicle and charge station. Modes 1, 2 and 3 use a battery charger inside the vehicle. Mode 4 uses an external battery charger that converts the AC in to DC. All modern electric and plug-in hybrid vehicles require communication with the charge station. IEC 62196 standard The plug configurations for mode 2 and 3 charging are described in the IEC 62196 standard: Type 1: based on the US SAE1772 standard. All American and Japanese cars (or other that use their technology) are supplied with this inlet. Type 2 is the European standard. European car makers will equip their cars with this inlet. Also infrastructure suppliers (Charging stations) in Europe use this standard for their outlets. Type 3 is a standard used in France and Italy on the infrastructure side. It uses shutters on the contacts for extra safety protection. HIGH STANDARDS Standards for electric vehicles and charging stations are quite complex and still in development for some areas. The most important standards for EV charging are: I IEC 61851 Conductive Charging systems, general requirements I IEC 62196 Plugs, connectors, outlet sockets and vehicle inlets for conductive charging.
