Considerations for Power Sharing

Wall Connector power sharing is achieved wirelessly.

For optimal performance, Wall Connectors within a power sharing network should be installed within 
view of each other whenever possible.

NOTE:

 Line of sight is recommended but not required. Wireless communication is capable of reaching 

around concrete corners but network range may degrade as a result.
Avoid placing Wall Connectors on opposite sides of concrete, masonry, metal studs, and other physical 
obstructions that would impede Wi-Fi signal strength.

NOTE:

 If a mobile device is able to connect to local Wi-Fi, it is a good indication that the Wall Connector 

will also be able to connect.

Calculating Power Sharing Requirements for Existing Systems

To calculate power supply requirements per number of Wall Connectors for existing electrical systems, 
use the following equation:

Available continuous 

amperage:

Number of Wall Connectors: Max amperage output per Wall Connector 

when 100% utilized:

_____________________ ÷ ________________________ = ________________________

NOTE:

 Maximum number of Wall Connectors for power sharing is 16.

NOTE:

 When calculating maximum amperage per Wall Connector, 100% utilization must be greater than 

6 amps for power sharing operation. If maximum amperage is greater than 48 amps, power sharing is not 
necessary.

For large scale sites, consider expected parking time in relation to a 100% utilization rate.

Expected Park Time (hours)

Examples

Recommended Amperage per wall 

Connector at 100% Utilization

6+ (long term)

Long term parking, overnight 

parking

12+ amps

3-5 (medium term)

Workplace, hospitality

24+ amps

1-2 (short term)

Shopping and dining

32+ amps

NOTE:

 100% utilization represents the worst case scenario for charging speeds, where the least amount 

of power would be available for each individual vehicle. In most situations, not all Wall Connectors would 
be actively charging a vehicle, which enables faster charging for the remaining vehicles.
