IEC 61851 Electric Vehicle Conductive Charging System

    IEC 61851 Introduction

    IEC 61851 lays the groundwork for conductive charging systems in electric vehicles and provides guidelines on safety, communication, and performance. It has charging personalities, connection interfaces, and control features that allow effective energy transfer between electric vehicles and charging stations. The standard helps in the interoperability of the different kinds of vehicles and electric charging systems. IEC 61851 has been used by engineers and testing laboratories to ensure that the system under test is not compromised by actual operating conditions. It also guarantees electrical hazards, overcurrent, and environmental stress protection. IEC 61851 is an important standard in the construction of standardized and reliable electric mobility charging networks.

    IEC 61851 Aggregate Testing Technique, Process, and Data Collection

    Testing begins with the setup and connection of the system to a controlled power source. Charging cycles are executed, and electrical, thermal, and communication data are logged by engineers. Voltage, current, and temperature data are logged and examined by the data logging system.

    IEC 61851 Results and Interpretation 

    Measures of performance are compared against a set of standard values to determine system performance. Safe and efficient charging is supported by consistent results. Any variation is a sign of errors in design or structure that need to be fixed.
