Abstract
(EN)
The present invention relates to the technical field of the charging and discharging of batteries, and in particular to a method and apparatus for testing the charging and discharging of a lithium battery. The method comprises: within the same time period, making at least one battery pack to be charged and discharged acquire electric energy from a power grid, and executing a battery pack charging action; and making the at least one battery pack to be charged and discharged transmit the electric energy to the power grid, and executing a battery pack discharging action. The present invention avoids the demand for large amounts of electric energy and the demand for a large power distribution capacity of a power grid when a charging test is independently performed on a lithium battery, and a power transmission and distribution device required to satisfy a power distribution capacity can be omitted; the demand for a large-load device when a lithium battery is independently discharged is avoided; and the charging cost can be reduced dramatically, thus having great economic benefits.

La présente invention concerne le domaine technique de la charge et de la décharge de piles et, plus particulièrement, un procédé et un appareil d'essai de charge et de décharge d'une pile au lithium. Le procédé consiste : pendant la même période, à amener au moins un bloc-piles devant être chargé et déchargé à acquérir de l'énergie électrique auprès d'un réseau électrique, et à exécuter une action de charge de bloc-piles ; à amener ledit bloc-piles devant être chargé et déchargé à transmettre l'énergie électrique vers le réseau électrique, et à exécuter une action de décharge de bloc-piles. La présente invention permet d'éviter la demande de grandes quantités d'énergie électrique et la demande d'une grande capacité de distribution d'énergie d'un réseau électrique lorsqu'un essai de charge est effectué indépendamment sur une pile au lithium, et un dispositif de transmission et de distribution d'énergie requis pour satisfaire une capacité de distribution d'énergie n'est pas nécessaire, la demande d'un dispositif de charge importante quand une pile au lithium est déchargée indépendamment est évitée, et le coût de charge peut être réduit de façon spectaculaire, ce qui présente des avantages économiques importants.
