urban rail vehicle lead acid Storage Battery with over voltage protection circuit
2011Co-Authors: Dongguang Liu, Jianping LiuAbstract:The utility model discloses an urban rail vehicle lead-acid Storage Battery with an over-voltage protection circuit. The urban rail vehicle lead-acid Storage Battery comprises a lead-acid Storage Battery and a temperature sensor which is positioned in a lead-acid Storage Battery box, wherein the positive end of the lead-acid Storage Battery is connected with a contactor and a charging resistor which are connected with each other in parallel; the lead-acid Storage Battery is also connected with a voltage comparison amplifier in parallel; the output end of the voltage comparison amplifier is connected with a controller; and a signal output end of the controller is connected with a control coil of the contactor. The urban rail vehicle lead-acid Storage Battery with the over-voltage protection circuit of the utility model solves the problems that the Storage Battery is over-charged, the service performance of the Storage Battery is reduced, the service life of the Storage Battery is shortened, and even the Storage Battery is subjected to thermal runway and is burnt down and the like because the floating charge voltage range acceptable to the lead-acid Storage Battery is narrow due to over-high voltage of a charger in an urban rail vehicle, so that the normal operation of the vehicle is guaranteed and the cost is reduced.
