CHARGE MANAGEMENT METHOD FOR AN ACCUMULATOR AND DEVICE THEREOF

摘要

In order that the charge current of an accumulator can be adjusted reasonably according to the temperature, the charge for the accumulator can be realized fast, safely and reliably, and the use-life can be prolonged effectively, the present invention provides a charge management method for the accumulator and a device thereof. The method includes the following steps: monitoring the discharge capacity of the accumulator, and determining the discharge depth of the accumulator according to the discharge capacity and the total capacity of the accumulator (S102); comparing the discharge depth of the accumulator with the pre-set cell equalization-charge threshold (S104); and when the discharge depth of the accumulator is more than or equal to the pre-set cell equalization-charge threshold capacity, a temperature-control charge mode, in which the charge current is adjusted according to the cell temperature, is enabled (S106).
