Scope

This document specifies the energy efficiency grades, minimum allowable values of energy
efficiency, and test methods for electric vehicle power supply equipment.
This document applies to non-vehicle-mounted conductive power supply equipment with a
rated voltage not exceeding 1,000 V (AC) on the power supply grid side and a rated voltage not
exceeding 1,000 V (AC) or 1,500 V (DC) on the electric vehicle side, and which uses current
control and/or voltage control. This includes DC power supply equipment (mode 4, case C
connection) and AC power supply equipment (mode 3, case B connection or case C connection).
This document does not apply to.
---Power supply equipment that only provides DC power on the power supply grid side;
---In-cable control and protection device (IC-CPD) for Mode 2 charging;
---AC/DC integrated power supply equipment;
---Integrated charging and storage equipment that does not have the function of charging
after disabling energy storage;
---Power supply equipment with automatic charging and top or bottom contact-type
charging.
NOTE. definitions of mode 2, mode 3, mode 4, case B connection and case C connection can be
found in GB/T 18487.1.
