Problems solved by technology

[0003] On the one hand, due to the long running mileage of the rail vehicle and the fast running speed of the train in the rail vehicle, for the battery pack installed at the bottom of the vehicle, the operating environment and temperature are relatively harsh, which will lead to rapid deterioration of the battery performance. Deterioration, which in turn may lead to failure of the entire battery pack, and in extreme cases may even lead to safety issues such as burning

Abstract

The invention discloses a battery monitoring system for a rail vehicle, which includes a battery data acquisition device, a data display device, a data transmission device, and a data control center, wherein the battery data acquisition device is used for collecting battery parameter information of a battery group in real time, and transmitting the battery parameter information to the data display device; the data display device is used for displaying the battery parameter information; the data transmission device is used for obtaining the battery parameter information from the battery data acquisition device or the data display device, and transmitting the battery parameter information to the data control center through a network; and the data control center performs statistic analysis on the battery parameter information and obtains a battery parameter-battery declining change rule of the battery group and the work state and service life of the battery group in the rail vehicle. The monitoring system helps to improve the rail vehicle operational safety.

Description

technical field [0001] The invention relates to the field of rail vehicles, in particular to a battery monitoring system for rail vehicles. Background technique [0002] At present, it is generally necessary to install a battery pack with sufficient capacity in a rail vehicle as a DC110V auxiliary power supply for its bow lift and emergency use. Among them, in the case of vehicle emergency, the emergency ventilation is required to be longer than 90 minutes, and the rest of the emergency electricity is required to be maintained for at least 2 hours, including emergency lighting, emergency display, emergency door opening, maintenance power, communication and its control, etc. [0003] On the one hand, due to the long running mileage of the rail vehicle and the fast running speed of the train in the rail vehicle, for the battery pack installed at the bottom of the vehicle, the operating environment and temperature are relatively harsh, which will lead to rapid deterioration of ...
