Abstract
(EN)
By determining the charge/discharge current value on the basis of the amount of time for charging and discharging and the battery state of the storage battery, directing the initiation of charging and discharging of the storage battery by using the PV power generated in a photovoltaic power generation (PV) system, the load power consumed by a load, and the storage battery output calculated by multiplying the storage battery voltage and the charge/discharge current value, and charging and discharging the storage battery at a calculated constant current, it is possible to obtain a storage battery charge/discharge control device and a storage battery charge/discharge control method which are capable of suppressing sudden increases and instant changes in the charge/discharge current value of the storage battery, even in cases in which PV power fluctuations and load power fluctuations occur suddenly, and which achieve degradation prevention and a longer operating life for the storage battery.

Selon la présente invention, par détermination de la valeur de courant de charge/décharge sur la base du laps de temps de charge et de décharge et de l'état de batterie de la batterie rechargeable, par commande du déclenchement de la charge et de la décharge de la batterie rechargeable à l'aide de l'énergie photovoltaïque (PV) produite dans un système de production d'énergie photovoltaïque (PV), de l'énergie de charge consommée par une charge et de la sortie de batterie rechargeable calculée par multiplication de la tension de la batterie rechargeable et de la valeur du courant de charge/décharge, et par charge et décharge de la batterie rechargeable, il est possible d'obtenir un dispositif de commande de charge/décharge de batterie rechargeable et un procédé de commande de charge/décharge de batterie rechargeable qui peuvent supprimer des augmentations soudaines et des changements instantanés de la valeur du courant de charge/décharge de la batterie rechargeable même dans des cas où des fluctuations de l'énergie photovoltaïque (PV) et des fluctuations de l'énergie de charge se produisent soudainement et qui arrivent à empêcher la dégradation et à atteindre une durée de vie plus longue de la batterie rechargeable.

 充放電を行う時間、および蓄電池の蓄電池状態に基づいて充放電電流値を決定し、太陽光発電(PV)システムにおいて発生したPV電力、負荷が消費する負荷電力および蓄電池電圧と充放電電流値を乗ずることで算出した蓄電池出力を用いて蓄電池の充放電開始の指示を行い、算出された一定電流で蓄電池を充放電することで、PV電力の変動および負荷電力の変動が急激に発生した場合であっても、蓄電池の充放電電流値の急激な増加および瞬時の変化を抑制することができるとともに、蓄電池の劣化防止および長寿命化を実現する蓄電池の充放電制御装置および蓄電池の充放電制御方法を得ることができる。
