GB 46519-2025 Minimum allowable values of energy efficiency and energy efficiency grades for electric vehicle power supply equipment

Scope

This document specifies the energy efficiency grade, energy efficiency limits, and test methods for electric vehicle power supply equipment.
This document applies to non-vehicle conductive power supply equipment with a rated voltage of no more than 1,000 V (AC) on the power supply side and a rated voltage of no more than 1,000 V (AC) or 1,500 V (DC) on the electric vehicle side, which is controlled by current or voltage. This includes DC power supply equipment (Mode 4, connection method C) and AC power supply equipment (Mode 3, connection method B or C).
This document does not apply to:
—— Power supply equipment that only provides DC power on the power supply side;
—— On-cable control and protection devices (IC-CPD) for Mode 2 charging;
—— Integrated AC/DC power supply equipment;
—— Integrated charging and storage equipment that does not have charging functionality after disabling the energy storage function;
—— Power supply equipment with automatic charging and top or bottom contact charging.
Note: The definitions of Mode 2, Mode 3, Mode 4, and connection methods B and C can be found in GB/T 18487.1.
