철도차량에 적용된 리튬폴리머 2차 전지 안정성에 관한 연구
양용준(Y. J. Yang),정수영(S. Y. Jung),서덕용(D. Y. Seo) 한국도시철도학회 2014 한국도시철도학회논문집 Vol.2 No.2
Need that must be complemented problems such as corrosion by electrolyte leakage of the secondary battery nickel-cadmium that is applied to a railway vehicle to data and fault checking are not available due to a lack of protection circuit. Secondary battery is a component to maintain continually stable performance and supply power to the railway vehicle on an ongoing basis. Lithium-ion with superior performance in energy capacity and stable operating voltage than nickel cadmium that was used to existing railway vehicles, by comparing the lithium polymer secondary battery, I have applied the lithium polymer battery for the first time in railway vehicle. The lithium polymer battery which was applied to the railway vehicle has drawbacks of low-temperature characteristics and price compared to the lithium-ion battery, but it shows that the safety and reliability especially in the risk of explosion are relatively higher than the lithium-ion battery. In spot of the unreasonable aspects price, It has excellent performance stability, safety and maintainability and also has a strength that exceeds the price in terms of efficient. In addition, the lithium polymer battery has the BMS to prevent overcharge and over-discharge and then manage the battery. In sopt of the unreasonable aspects price, It has excellent performance stability, stability, safety and maintainability and also has a strength that exceeds the price in terms of efficient. In addition, the lithium polymer battery has the BSM, PCM to prevent overcharge and over-discharge and then manage the battery. Protection operation circuit is constituted by a system that constantly monitors the voltage, current, and temperature. Throughout the study, such as temperature change of battery cell due to the temperature rise in a scorching summer of the lithium polymer battery, discharge performance and the operation of the safety protection circuit in operation which are applied to urban railway vehicles of Seoul Metro was confirmed reliability and safety.
