リチウムイオン蓄電池の充放電エネルギー効率劣化の差電圧指標によるモデル化

抄録

A large amount of variable renewable energies has been introduced, simultaneously, the energy storage, for example, lithium-ion batteries became necessary because of the fluctuation and surplus of them. For efficient use of them, we studied the method of charge-discharge energy estimation. It was constructed as a method applicable to any current and state of charge sections. According to the analytical studies of estimation error characteristics, it was suggested that this method was suitable to the stable lithium-ion batteries aimed to absorb the photovoltaic energy surplus.
