The terms and definitions defined in GB/T 18487.1 AND the followings apply to this document.
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. 3.3
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 temperature.
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
6.1 Layout requirements
Following factors shall be considered for layout of transformer room, power distribution room and power distribution box within the charging station.
a) Shall not hinder the development of charging station; and the possibility of expansion shall be considered.
b) Shall be located at the side to the incoming line of power supply within the charging station.
c) It is easy to enter and exit the power supply line.
d) It is easy to transport equipment.
6.2 Technical requirements
7.1.1 The layout of charging equipment shall be easy to park the electric vehicles to be charged, and carry out operation by charging personnel.
7.2.2 When several vehicles are charged simultaneously, each charge and vehicle shall not affect the charging of other chargers and vehicles.
7.2.3 When the charging equipment is installed outdoor, the rain and snow proof ceiling shall be installed.
7.2.4 When the charging equipment is installed indoor, ventilation facilities shall be installed to prevent overheating.
7.2.5 The charging equipment shall be installed with a certain height from the ground to meet the requirements for rain and accumulated water-proof.
7.2.6 The layout of charging equipment shall make the length of charging cable as short as possible in order to save material and energy consumption.
8 Monitoring-control system
8.1 Composition
The monitoring-control system of charging station consists of charging monitoring-control system, power supply monitoring-control system, and safety-protection monitoring-control system.
8.2 Charging monitoring-control system
8.2.1 Basic functions The charging monitoring-control system achieves monitoring, protection, control and management of charging equipment during operation and charging, and emergency treatment in case of an accident, as well as data storage, display and statistics.
