3 Terms and definitions
The terms and definitions defined in GB/T 18487.1 AND the followings apply to this
AC charging spot
AC power supply unit
The special device which provides AC electric energy for the electric vehicle with
vehicle-mounted charger by using conductive mode.
Off-board charger
The special device which is fixedly mounted on the ground, converts the grid AC to DC,
and charges the power storage battery for electric vehicle by using conductive mode.
Charging equipment
The special equipment providing electric energy for the storage battery of electric vehicle,
including AC charging spot, off-board charger and so on.
EV charging station
The place where three or more EV chargers (with at least one off-board charger) are
available and can carry out condition monitoring of the chargers during charging the
electric vehicle.
EV charging system
5.3 The charging station within the urban area shall be close to the urban roads, but shall
not be in the vicinity of the intersection of urban arterial roads and heavy traffic roads.
5.4 A reasonably safe distance between the charging station and important or
personnel-intensive public buildings such as party and government office buildings,
primary and secondary schools, kindergartens, outpatient building and inpatient buildings
of hospitals, large libraries, cultural relics and historic sites, museums, large stadiums,
movie theaters and so on.
5.5 The charging station shall be kept away from the place with potential hazards, and
shall comply with relevant provisions of GB 50058 in the case of adjoining buildings with
explosion or fire hazards.
5.6 The charging station shall not be located in the places with dust or corrosive gases,
and shall not be located at the downwind side of the prevailing wind direction of source of
pollution when such sources cannot be avoided.
5.7 The charging station shall not be located in the place with severe vibration or high
5.8 The charging station shall not be located in low-lying places or places possibly
accumulating water.
5.9 The charging area shall be well ventilated.
5.10 For some areas where severe wet weather may occur, equipment and tools for
monitoring and treatment of air humidity shall be available.
6 Power-supply systems
