METHOD AND APPARATUS FOR TESTING CHARGING AND DISCHARGING OF LITHIUM BATTERY

摘要

The invention relates to the technical field of 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, enabling at least one battery pack to be charged and discharged to acquire electric energy from a power grid, and performing a battery pack charging action; and enabling at least one battery pack to be charged and discharged to transmit electric energy to the power grid, and performing a battery pack discharging action. The invention avoids the demand for a large amount 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.
