리튬이온 배터리 동특성 및 안전성 평가를 위한 배터리 시뮬레이터 시험설비 = Test Facility of Battery Simulator for Dynamic Characteristics and Safety Evaluation in Lithium-ion Battery

다국어 초록 (Multilingual Abstract)

Lithium-ion batteries are used in many fields due to their high energy density, fast charging conditions, and long cycle life. However, overcharging, over-discharging, physical damage, and use of lithium-ion batteries at high temperatures can reduce battery life and cause damage to people due to fire or explosion due to damage to the protection circuit. In order to reduce the risk of these batteries and improve battery performance, the characteristics of the charging and discharging process must be analyzed and understood. Therefore, in this paper, we analyze the charging and discharging characteristics of lithium-ion batteries using a battery charger and discharger and simulator to reduce the risk of loss of life due to overcharge and overdischarge, as well as casualties from fire and explosion due to damage to the protection circuit.
