The widespread adoption of electric vehicles (EVs) faces significant infrastructure challenges, particularly regarding charging accessibility. This thesis investigates peer-to-peer residential charger sharing (P2P-EVSE), an innovative system that connects households with underutilized electric vehicle supply equipment (EVSE) to EV drivers seeking convenient charging options. This research examined the feasibility and acceptance factors of P2P-EVSE platforms through a comprehensive survey of 367 California households with EVs. The study employed a mixed-methods approach, combining quantitative survey analysis with qualitative assessment of user preferences and concerns. The survey instrument included questions about charging habits, sharing preferences, economic motivations, personality traits, and demographic characteristics.Analysis of survey responses revealed that 28% of respondents showed interest in hosting their chargers, while 31% expressed willingness to rent through P2P-EVSE platforms. Statistical analysis identified economic incentives, outgoing personality traits, and support for alternative charging policies as the strongest predictors of participation intention. Hosts prioritized damage reimbursement guarantees and equipment control, while renters emphasized convenience and cost savings. Both groups cited liability concerns as the primary participation barrier, with environmental benefits being a secondary consideration. The findings demonstrated that EV owners in detached houses showed reduced interest in renting, while high-mileage drivers and those with daily charging needs exhibited increased willingness to participate. The research suggests that P2P-EVSE could particularly benefit multi-unit dwelling residents, addressing a known barrier to EV adoption. Higher adoption potential is predicted in regions like Southern California, where significant cost differences exist between home and public charging options.
