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.
