The Simulation of Vehicle-to-Home Systems – Using Electric Vehicle Battery Storage to Smooth Domestic Electricity Demand

We present a study into the feasibility of vehicle-to-home technology. A model of a single
house and single electric vehicle operating vehicle-to-home was developed in MatLab Simulink ®.

The model takes an input household appliance demand profile and vehicle use data and controls the
power flow between the electric grid, the appliances and the vehicle. Running the appliances off the
vehicle battery in an attempt to reduce the household peak power demand is the aim in vehicle-tohome.

Three commutes of distance 2 miles, 30 miles and 80 miles were simulated to investigate the
effect of vehicle use on vehicle-to-home. The two shorter distances allowed vehicle-to-home to work
with no problems.

The 80 miles journey was at the limit of the electric vehicle range and therefore
caused a small problem when operating vehicle-to-home. All three cases reduced the peak power
demand and increased the load factor. These modifications to the household demand profile would
potentially be environmentally and financially beneficial to the electrical generation sector.

Electric Vehicle Batteries Could Reduce Household Peak Power Demand

Tech On, an industry newsletter, today said that Mitsubishi’s PX-MiEV plug-in hybrid vehicle — on display at the Tokyo Motor Show — is designed for V2H applications in a smart-grid environment.
