Lithium-ion batteries for reserved power supply of railway automatics and communication devices
Journal Title: Електромагнітна сумісність та безпека на залізничному транспорті - Year 2017, Vol 1, Issue 14
Abstract
The purpose of the research work is to solve the problem of improving the electrical energy quality parameters and facilitating work of service staff by upgrading the reserved power supply system of railway automatics and communication devices. This can be achieved by the analysis of the possibility of using new generation lithium-ion batteries at the electrical interlocking posts, crossings and in communication devices. Comparative characteristics were done for modern lithium-ion batteries of small and large capacity. The possibility of using modern types of lithium-ion batteries is estimated as reserve sources for power supply of automatics devices. The operation modes of lithium-ion batteries are considered. Applying of lithium-ion batteries of a new generation with a capacity of 100…360 A•h in railway automatics devices will reduce the size and weight in 5…10 times, free up the premises, and also eliminate harmful working conditions that arise at the caring for lead and alkaline bat-teries. At the same time, the service life of the batteries increases from 7…10 to 20…25 years. The economy of money will be improved. It based on the cost of periodic replacement and utili-zation of lead and alkaline batteries. So, the economy of money resources at operation of lithium-ion batteries for 20 years will make not less than 350 %. The possibility of using flexible lithium-ion batteries as sources of power supply is considered for portable radios. A typical scheme was proposed for charging such batteries based on the SC80x microcontrollers.
