Recently, many countries are researching and developing the various Electric Vehicle(EV) for reserving their natural environments and so on. But the charging time that is longer than the time of filling up the traditional engine vehicle will be the obstacles of spreading them. So, the other type EV is developed. It is the Battery Changeable EV. But there is not testing method for it. Especially, the defining of the durability evaluation for the couplers between battery and charger is very important because the couplers are changed very frequently. So, they may cause many faults and problems. Therefore, this study shows the definition of the durability procedure and the test is conducted with the equipment.

Combined generation system of photovoltaic and wind power is required backup system that such as a storage battery to supply energy, when not enough photovoltaic and wind power source for power supply equally and continually, because the energy source is changeable and stable through change of weather as irradiation, temperature, wind speed, wind speed, wind direction, seasons, etc..

Combined generation system of Photovoltaic and wind generation have shortcoming that is different output power according to change of weather. So, the combined generation system is required backup system that such as a storage battery to supply energy, when not enough photovoltaic and wind power source for power supply equally and continually because the energy source is changeable and stable through change of weather as irradiation. temperature, wind speed. wind direction. seasons, etc.
