This paper proposes a model for city-scale EV infrastructures. Recent advances both in EV battery technology and alternative battery ownership formulations have created favorable conditions for houses where EVs are used not only for commuting but also as one of the main power supplies. Power supplied by EVs is a natural complement for solar panels, where the former is the only choice at night when solar panels cannot function by definition. The proposed model is based on a system of practical considerations with the main objective to build simulations as close to reality as possible. The model is applicable to a wide range of simulations including EV infrastructures, distributed power microgrids, smart cities, etc.

    • . What it is about: Taxonomy • LEASE: leasing (not buying) a battery -- a battery ownership model • V2H: vehicle to home, powering your home from your EV • FAST: the recharge/refill is fast • SIMPLE: recharge/refill is simple and can be done on commodity hardware • HABIT: ho major change in people's habits is required -- same as gas station? V2H FAST SIMPLE FAST SIMPLE Charging LEASE Replacement Fast charging HABIT V2H M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ... EV Use in ...

    • . What it is about: Contributions 1. maps of real roads 2. a throughput model for battery replacement station 3. a user model for commute and V2H use 4. the concept of social utility M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ...

    • . The Scope: the Full Model • assumes that battery replacement is the default mode • scale: a city, specifically Tokyo in this study ◦ Note: real road graph (GIS/.shp) but working on Google Maps as well 14 14 myself "Google Maps 2 Road Graphs Project" https://github.com/maratishe/maps2graphs (2013) M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ...

    • . The Scope: One Household • ignore solar panel for now • battery stations can be near home or near work • model: live in suburbs, work in city M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ... EV Use in ... V2H and Battery Replacement.... -- http://tinyurl.com/kyutech131017 9/19 ... 9/19

    • . Social Utility . EVU... .. .... is the uitlity of owning an EV EVU = commutes in EV total commutes (1) • failed replacement = two lost commutes -- you leave the car and have to go back for it • weekdays only . V2HU... .. . .. is the utlity of using your EV to power your home V2HU = hours used at home all night hours (2) • during the day (when EV is away), you can use a solar panel or traditional power plant • useless if EV is home but has no charge M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ...

    • . Simulation Setup • EV: 150km on full charge, 24kW • station: 24 EVs per hour, capacity parameter to control throughput • city: find the center of the graph and set the city/suburbs border as a fraction of that • between 2k and 20k EVs in the city M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ...

    • . Results: Social Utility • EVU is much smoother and has better response to increasing number of stations • in V2HU, there is a small group of users who are not doing well -- abrupt tail M.Zhanikeev (Kyutech) -- maratishe@gmail.com -- ...
