The Economics of Non-Residential Level 2 EVSE Charging Infrastructure

The paradigm for residential EV charging via a Level 2 EVSE is well established, and is a low-cost, highly convenient way for the EV driver to recharge for those with a dedicated parking space (e.g., garage). Residential charging has other potential benefits relative to electric utility demand response and emergency home power. For residences without such EVSE ready availability (e.g., multi-unit dwellings, street parking), other charge options may be necessary. Non-residential Level 2 charging is a still-evolving business case. The non-residential EV charging model is complicated by a number of issues, including: the need for credit card systems at many venues, the question of roaming, communications and control with utilities, data reporting, the need to accommodate subscription networks, and site host requirements. This paper discusses the economic considerations and potential trade-offs for both the EV driver and the charge station site host for the following non-residential Level 2 charging venues: Workplace (offices, manufacturing, fleets) Parking structures/lots Publicly-accessible venues (courts, train stations, malls, museums, restaurants, grocery stores, etc.
