Abstract:
Electric vehicles should be connected to power system for charge and discharge of battery. Besides vehicle's
battery is charged for a power source, it is also reversibly possible to provide power source from battery to
power system. Researches on battery usage for regulation resources have been progressed and could cause
cost increase excessively because they distribute regulation capacity equally without considering the battery
wear cost of SOC, temperature, voltage and so on. This causes increase of grid maintenance cost and
aggravate economic efficiency. In this paper it is studied that the cost could be minimized according to the
battery condition and characteristic. The equation is developed in this paper to calculate the possible number
of charge and discharge cycle, according to SOC level and weighting factors representing the relation
between battery life and temperature as well as voltage. Thereafter, the correlation is inferred between the
battery condition and wear cost re
flecting the battery price, and the expense of compensation is decided
according to the condition on battery wear-out of vehicle.
