|
Electric Vehicle Charging Stations (Chapter XI-11.7) |
|
| Public Charging Stations | Private charging at residences offices shall be permitted. Distribution Companies (DISCOMs) may facilitate the same. |
| Public Charging Stations (PCS) shall be a de-licensed activity and any individual/entity is free to set up public charging stations provided that, such stations meet the technical, safety as well as performance standards and protocols laid down below as well as any further norms standards specifications laid down by Ministry of Power and Central Electricity Authority (CEA) from time to time. | |
| PROTECTION | All electric vehicle charging stations shall be provided with protection against the overload of input supply and output supply fittings. |
| The electric vehicle charging station shall be equipped with a protective device against the uncontrolled reverse power flow from vehicle. | |
| Suitable lightning protection system shall be provided for the electric vehicles charging stations as per Indian Standards Code IS/ IEC 62305. | |
| A cord extension set or second supply lead shall not be used in addition to the supply lead for the connection of the electric vehicle to the electric vehicle charging point and it shall be so constructed so that it cannot be used as a cord extension set. | |
| An adaptor shall not be used to connect a vehicle connector to a vehicle inlet. | |
| HEIGHT | All electric vehicle charging points shall be installed so that any socket-outlet of supply is at least 800 MM above the finished ground level. |
| AREA | The electric vehicle parking place shall be such that the connection on the vehicle when parked for charging shall be within 5 meters from the electric vehicle charging point. |
| Portable socket-outlets are not permitted to be used for electric vehicle charging. | |
| D.C Charging | A vehicle connector used for Direct Current (D.C.) charging shall be locked on a vehicle inlet if the voltage is higher than 60 V D.C. and the vehicle connector shall not be unlocked (if the locking mechanism is engaged) when hazardous voltage is detected through charging process including after the end of charging and in case of charging system malfunction, a means for safe disconnection shall be provided. |
| The Direct Current (D.C.) electric vehicle charging point shall disconnect supply of electricity to prevent overvoltage at the battery, if output voltage exceeds maximum voltage limit sent by the vehicle. | |
| The electric vehicle charging points shall not energize the charging cable when the vehicle connector is unlocked and the voltage at which the vehicle connector unlocks shall be lower than 60V. | |
| Earth protection system for charging stations. | All Residual current device for the protection of supplies for electric vehicle shall |
| (a) have a residual operating current of not greater than 30 Ma | |
| (b) interrupt all live conductors, including the neutral | |
| (c) have a performance at least equal to Type A and be in conformity with IS 732-2018. | |
| Each electric vehicle charging points shall be supplied individually by a dedicated final sub-circuit protected by an overcurrent protective device complying with IEC 60947-2, IEC 60947-6-2 or the IEC 60269 series and the overcurrent protective device shall be part of a switchboard. | |
| All electric vehicle charging stations shall be supplied from a sub-circuit protected by a voltage independent residual current device and also providing personal protection that is compatible with a charging supply for an electric vehicle. | |
| All electric vehicle charging stations shall be provided with an earth continuity monitoring system that disconnects the supply in the event that the earthing connection to the vehicle becomes ineffective. | |
| A protective earth conductor shall be provided to establish an equipotential connection between the earth terminal of the supply and the conductive parts of the vehicle which shall be of sufficient rating to satisfy the requirements of IEC 60364-5-54. | |
| Fire Fighting System in electric vehicle charging stations | Enclosure of charging stations shall be made of fire retardant material with self-extinguishing property and free from Halogen. |
| Fire detection, alarm and control system shall be provided as per relevant Indian Standards. | |
| Power supply cables used in charging station or charging points shall conform to IEC 62893-1 and its | |
| Testing of charging stations | All apparatus of charging stations shall have the insulation resistance value as stipulated in the relevant IEC 61851-1. |
| Inspection and periodic assessment of charging stations. | Every charging station shall be tested and inspected by the owner or the Electrical Inspector or Chartered Electrical Safety Engineer before energization of charging stations. |
| The owner of the charging station shall ensure that test and inspection of charging station is being carry out every year in the initial period | |
| MAINTENANCE RECORDS | The owner of the charging station shall keep records in regard to design, construction and labelling to be compatible with a supply of standard voltage at a nominal frequency of 50 Hertz of the charging station. |
| The owner of the charging station shall keep records of the relevant test certificate as indicated in these regulations and as per IEC 61851. | |
| The owner of the charging station shall keep records of the results of every inspection, testing and periodic assessment and details of any issues observed during the assessment and any actions required to be taken in relation to those issues. | |
