End of train (EOT) system having temperature control for optimized battery charging

摘要

An end of train (EOT) system (10) includes monitoring equipment (20) with a sensor (22) to monitor a pressure of air in a brake mechanism (14) in a railcar, and a power supply (40) having battery cells (38) and a temperature control system (44) for the battery cells (38). The temperature control system (44) includes a heat sink (46) in heat transference contact with the battery cells (38), and an electronically controlled heater (48) for the battery cells (38). The temperature control system (44) includes a temperature sensor (50), and a control device (34) coupled with the temperature sensor (50) and the electronically controlled heater (48) to vary an output of the heater based on an output of the temperature sensor (50).
