Checklist for pre-planning a charging infrastructure	
Summary of influencing factors and project particularities 	
Project profile			
	New construction		Integration in an existing installation	
Project location:			
Date of implementation:			
User of the charging infrastructure: e.g. employees, hotel guests, park-and-ride users, shopping customers, long-term parkers, charge-and-drive users, etc.:			
Assets such as open parking garages, underground garages, electric service stations, parking areas, etc.:			
Number of floors with charging points:			
Number of charging points per floor:
(multiple entries possible)			
Dimensions of the parking level with charging points L x W: (multiple entries possible)			m	
Average floor height:			m	
Expandability (e.g. number of future charging points):			
Billing methods of charging energy provision: 
cost lump sum, exact billing of kWh, or free of charge: (multiple entries possible)			
	
Use of load management system	

			
Other specifications:			

			
Product selection 			
Selection and planned number of necessary charging points, the prospective available charging time (for an overview of typical charging times for different applications, see table 1) and if known, the information on the battery capacities:	

AC - charging
Wallbox	
DC – charging
fast charging station	
DC – charging
for fleets	

Quantity of charging points	

	

Charging time 

	

If known, the battery capacity in kWh

	

	
Table 1: Typical charging times for different applications
Locations for charging infrastructure	
Company parking lots on their own property for employees	
Car stops, 
highway rest area, business park	
Parking garages, customer parking of shopping centers	
Bus depot	

Prospective available charging time	
6 - 8 h	
20 min - 3 h	
2 - 4 h	
6 - 8 h	

Demand characteristic 			
In many cases, it is only possible to charge an amount of energy which corresponds, on average, to a shorter driving distance than that of a full charge. Please make a selection for the requested charging amounts (= driving distances) – e.g. 60% for distances ≤ 40km and 40% for distances ≤ 80km	
	≤ 40 km:			
	≤ 80 km:			
	≤ 120 km:			
	≤ 160 km:			
	Electric vehicles should be charged to a maximum as far as possible			
	Other specifications:			
				
Network connection			
			
	Medium-voltage connection		Low-voltage connection	
Power demand announced:			kW	
	Expansion of grid connection required			
Available power for the charging infrastructure, 
if given:			kW	
Other specifications:			
			
Requirements on power supply 	
Infeed availability:	

	
No redundancy	
	
Partial redundancy	
	
Full redundancy	

Use of self-generation planned, e.g. PV	

	
Use of battery storage planned, e.g. for avoidance of peak loads
