Coulomb The business of Charging Coulomb’s Business

• Coulomb’s mission is to ensure people don’t hesitate to buy electric because of fueling concerns

• We realize our mission by providing a toolkit of everything a company needs to offer charging services to drivers

• We are a business model company – our toolkit gives station owners what they need to maximize revenue and minimize cost

• We do that by offering cloud services and charging station hardware products

2 The State of EVSE Networking

• What people are getting from it today o Real time station status – no use searching for stations that might be in use o Reservations – Not many station owners have enabled it o Billing – by KWH, time, or session o Authentication – keeping your neighbor from charging o Record-keeping – providing data to station owners, governments, and drivers o Reliability – providing station owners and drivers knowledge of broken stations o Utilization – tells station owners when they need more charging spaces o Driver notifications – when cars are charged up, when they’re interrupted, when you forgot to plug in

• What is just starting to be used o Demand Response o TOU Price signaling o Employee compensation measurement Charging Service Models

14 Myth Busting

Myth Reality Because most charging will be done at 1) 31% of Americans live in MDUs home, shared charging isn’t interesting 2) 20% of Charging will be public Plug-in Hybrids don’t need charging The smaller the battery the more stations people charge. PHEV drivers get gas anxiety Better battery technology will mean Better battery technology will mean cars will have enormous range cars will be affordable
