摘要： Disclosed is a cell balancing apparatus and method using a voltage variation pattern of a battery cell, which measures voltage of each cell, estimates OCV or SOC of each cell using a voltage variation pattern of each cell including a present voltage and a past voltage, and eliminates a deviation in OCV or SOC between the cells through comparison of the estimated OCV or SOC of each cell. In estimating the OCV of each cell, an output voltage error due to IR drop is corrected. Thus, SOC of each cell may be accurately estimated. And, an accurate estimation of SOC may render substantial elimination for a SOC deviation of each cell. Furthermore, SOC estimating using an output voltage leads to an active cell balancing even during charge and discharge of battery, thereby minimizing an SOC deviation of each cell.

摘要： An apparatus balances a charging voltage of each battery cell of a battery pack. The apparatus includes a discharge resistor installed on a conductive line connected to both ends of a battery cell in parallel; a balance signal relay unit for relaying a charging voltage of the battery cell according to a balance control signal; and a discharge switching unit for receiving the relayed charging voltage of the battery cell as a driving voltage and connecting the battery cell to the discharge resistor to discharge the battery cell if the driving voltage is over an effective voltage level. This apparatus prevents overcharging of a battery cell, caused by a failure of a control processor, while balancing a charging voltage of battery cells. Also, the control processor may be protected against an electric impact by electrical insulation from a discharge circuit. Accordingly, the safety of the battery pack is improved.

摘要： The present invention relates to a method for recovering methane gas by adding a gas mixture containing N2 and CO2 gases to natural gas hydrate and reacting them. The method for recovering methane gas from natural gas hydrate of the present invention comprises the step of replacing CH4 gas in natural gas hydrate with a gas mixture containing N2 and CO2 gases by adding the gas mixture to the natural gas hydrate. The method for recovering methane gas of the invention assures a recovery rate of CH4 gas much higher than prior art method without dissociating natural gas hydrate layer and utilization of flue gas as a gas mixture containing N2 and CO2 gases, which makes possible its practical application for the production of natural gas in terms of economy and environmental protection.
