Comes with the Car. 8-12 hrs Level 2 – most popular. Faster charge. Home Workplace. 4-8 hrs DC quick – fastest charge available. Less than 30 min. CHAdeMO = Nissan Leaf and Mitsubishi vehicles CCS Combo = Combined Charging System (use single port for Level 1, 2 and DCFC) = Chevy Spark and BMW i3 BEV Full Charge ~12-16hrs 2-5 miles per hour BEV Full Charge 4-6hrs 10-20 miles per hour BEV Full Charge ~30mins 50-70 miles per 20 mins

Networked vs. Non-Networked? Who will be able to charge at your stations? How do you want them to access it? Planning to “charge” for charge? Need to track energy usage or reporting capabilities? Who will you maintain your station(s)? How? Networked Network subscription plan Automated payment processing, usage tracking, reporting etc. Ideal for Public charging. Divers can locate stations and access using credit card or network-card. Easier to manage pricing and station health Non-Networked Low cost; no annual fee RFID for access control Ideal for Private charging; for defined user-base. Simple for drivers, and station owners.. Does your customer want a basic or connected station? Use this slide to help them decide what best fits their needs.

DCFC Landscape 2015-Q1

Installation Considerations: Wall vs. Pedestal Closest to electrical service panel vs. Main Entrance Select panel that can accommodate additional stations, and consider pre-wiring Save on footprint with dual- connector models; consider installing at the “cross” btwn 4 spots Consider solar car-ports for off- grid tied solutions Wallmount delivered significant savings at our Carrollton, TX office  $6k vs. $1k for installation of one-dual level 2 EVSE including bollards Closest to electrical service panel vs. Main Entrance Select panel that can accommodate additional stations in the future; consider pre-wiring while work is already being done Save on footprint with dual-connector models; consider installing for 4 spots at the “cross” Consider solar car-ports for off-grid tied solutions

Installation Tips: Before wiring: check reception; consider signal repeater/booster if needed Don’t forget “activation & commissioning”; some networked stations will not charge until this step is performed. Signage with metal signs and/or asphalt paint on parking spots; and bollards. EVSE hardware/wiring installation is straight forward for any electrical contractor; best to engage a contractor already be familiar with your infrastructure (saves you more time and money); simply give them a copy of the installation guide.. Point them to where you’d want to install… and ask them to provide quotes /recommendations Don’t forget about “Activation & Commissioning” (which is connecting and activation station on the network, your “part II” of install following electrical); best to inquire about this service from EVSE provider. For Example, Schneider offers this in our Prime Service Package as a bundled deal with a 3yr pre-paid network subscription plan. Signage with metal signs and/or asphalt paint on parking spots serve dual functions – 1) helps EV drivers easily locate charging, 2) helps EV drivers from getting “ICEd” by clearly marketing EV-Charging-Only dedicated spots.

Do I “charge” for charge? Public: 63% Free, 37% Paid Private: 76% Free, 24% Paid More public access vs. Private
