GB/T 29316-2012Power quality requirements for electric vehicle charging/battery swap infrastructure (English PDF)

Foreword

This Standard is drafted according to the rules stated in GB/T 1.1-2009.

1 Scope

This Standard specifies the relevant standards and testing requirements of power quality for charging facilities of electric vehicles.

This Standard applies to the charging facilities of electric vehicles, including AC charging piles and charging stations.

3 Terms and Definitions

The terms and definitions defined in GB/T 12325, GB/T 14549, GB/T 15543, GB/T 19862,

GB/T 29317 and GB/T 29772 apply to this document.

4 Supply Voltage Deviations

4.1 The supply voltage deviations for charging facilities of electric vehicles shall meet the requirements in Table 1.

5 Voltage Unbalance

5.1 When charging facilities of electric vehicles access to public grid and the power grid is under normal operation, the unbalance of negative sequence voltage at the point of common coupling shall not exceed 2%, and shall not exceed 4% in short time.

6 Harmonic Limits

6.1 The harmonic voltage limits (phase voltage) when charging facilities of electric vehicles access to common coupling point in public grid are required to meet the provisions of GB/T 14549.

6.2 The allowable value for harmonic current when charging facilities of electric vehicles access to common coupling point in public grid shall meet the provisions of GB/T 14549.

6.4 In rated power output of on-board battery charger accessed with AC charging pile, total harmonic distortion of current on AC input side shall be equal or less than 8% with power factor equal or greater than 0.95.

7 Power Quality Detection

7.1 The power quality detection point of charging facilities should be selected from inlet wire of power supply; monitoring equipment should select Class A equipment that accords with the provisions of GB/T 14549. […]
