Can ev charging stations be installed in underground manned parking spaces?

I. Can I install ev charging stations in my manned parking space?

As long as a long-term lease contract is signed, the property can be applied to the local air defence management department and the charging pile can be installed without affecting the function.

In addition, new energy vehicle charging stations can be installed in underground human defence parking spaces, and the protection effectiveness of the human defence project shall not be affected during installation and use. At the same time, the installation shall be carried out in accordance with the requirements and provisions of the Notice on Accelerating the Construction of Electric Vehicle Charging Infrastructure in Residential Areas and the Engineering Technology Standards for Decentralized Charging Facilities for Electric Vehicles, and fulfill the relevant installation procedures.

II. The general electrical requirements for human defence electromechanics

1、Lightning protection grounding

Work grounding: grounding of power distribution, grounding of protection duty room, grounding of power station generator.

Protection grounding: equipment room grounding, metal wire pipe, electrical metal wire pipe, metal bridge (cable channel box) grounding, metal electric door (electric fire shutter door) grounding, grounding of mechanical parking space.

Anti-static earthing: grounding of boxes, grounding of oil pipelines, grounding of oil unloading vehicles.

Shielding earthing: metal door frame of anti-door, ambulance works, structural steel mesh of command works, earthing of oil mesh filter, pre-buried pipe earthing of human defence wind, water and electricity, etc.

1). Work grounding and weak power grounding grounding resistance less than 1 ohm.

2). Each door frame angle iron with 25*4 hot dip galvanized flat steel and bottom plate upper layer of steel welding, this upper layer of steel and welded steel mesh should have at least one point of welding connection. As shown below.

3). The grounding of the human protection distribution box leads on line, 40 x 4 hot-dip galvanized flat steel directly to the distribution box.

4). Equipment room protection grounding, from the grounding network lead on - 40 × 4 hot galvanized flat steel to 0.3M from the ground at the pre-buried galvanized steel welding.

5). Diesel generator room for protective earthing, lead up from the earthing grid -40×4 hot-dip galvanized flat steel to 0.3M from the ground with pre-buried galvanized steel plate welding.

6). For grounding of metal pipes etc., lead up from the grounding grid -40×4 hot-dip galvanized flat steel to 0.3M from the ground and weld the galvanized steel plate.

7). For anti-static grounding of fuel facilities in power stations, the grounding grid is led on -40×4 hot-dip galvanized flat steel to 0.3M from the ground and pre-buried galvanized steel plate is welded.

2. Cable (open piping) through the enclosure structure practice.

1). Bridge can not be directly through, to be changed through the human security pre-buried pipe.

2). The cable to be used in both civilian and warfare or in wartime must meet a line of a tube.

3). Cables used only in peacetime and dismantled in wartime may not require one line and one pipe

4). In the event of war (before the outbreak of war), they shall be protected or sealed as required.

5). Cables running through fire protection zones in normal times shall be subject to fire protection measures as required.
