Problems solved by technology

However, the various components forming the individual channels show performance differences even at the production stage
In addition, the degree of deterioration of various components may change over time
If the level of charge and discharge performance is different for each channel, the characteristics of the produced battery differ for each channel

Abstract

The present invention provides a system for charging-discharging device of a secondary battery, which comprises the following components: a charging / discharging device, a calibrating unit and a metering unit, thereby easily executing calibration operation of the charging / discharging device without individual battery tray. In one embodiment, the system comprises the following components: the calibrating unit which is used for calibrating charging / discharging function of the charging / discharging device, the metering unit which is used for measuring charging / discharging function of the charging / discharging device, and a metering / calibrating selection relay unit which is provided between the calibrating unit and the metering unit and switches calibration operation of the calibrating unit or metering operation of the metering unit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2011-0011865 filed on February 10, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] Aspects of the present invention relate to a system of a charging and discharging device for a secondary battery. Background technique [0004] With the development of electric / electronic technology, compact and lightweight portable electronic devices having various functions are rapidly being used. Batteries are generally used as power sources for driving portable electronic devices, and rechargeable secondary batteries are mainly used. [0005] Since typical secondary batteries, such as nickel-cadmium (Ni-Cd) batteries, lead storage batteries, etc., are put into use after they are manufactured, charging and discharging devices are only required for evaluating the performance of the batteries. However, cells of lit...
