Problems solved by technology

[0003] At present, the backup power supply of EMUs mostly adopts the nickel-cadmium battery pack system. This system has no self-test and protection functions, and blind charging and blind discharging are implemented. With the same capacity, the weight is heavy, the capacity decays quickly, and the pollution is large after the battery is scrapped.

Abstract

The invention discloses a rail traffic backup power supply system which comprises an overall main control unit, a lithium battery pack, a load, a battery management module and a vehicle-mounted recharger, wherein the battery management module comprises a battery management main control unit, a sampling module, a balance module, a detection estimation module, an over-charge signal partition transmission module, an over-discharge signal partition transmission module, a first signal cascading terminal and a second cascading terminal; the sampling module is used for collecting sampling signals ofthe lithium battery pack; the battery management main control unit is used for receiving sampling signals from the sampling module and used for transmitting the sampling signals to the over-charge signal partition transmission module or the over-discharge signal partition transmission module; the first signal cascading terminal is used for receiving indication signals and used for transmitting theindication signals to the overall main control unit through the second signal cascading terminal. By adopting the rail traffic backup power supply system, lightening and no pollution of a storage battery pack are achieved, and meanwhile due to adoption of a battery management system of a specific structure, the reliability and security of the power supply system are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a backup power supply system for rail transit. Background technique [0002] With the rapid development of rail transit, rail transit has become one of the most convenient, economical and efficient means of transportation for people to travel; at the same time, higher and higher requirements have been put forward for the safe and reliable operation of rail transit. When the power supply to the rail transit is abnormal for some reason, it will seriously affect the rail transit. Therefore, we need to install a set of backup power system on the train to deal with emergencies. The backup power system needs to be highly reliable. sex. [0003] At present, the backup power supply of EMUs mostly adopts the nickel-cadmium battery system. This system has no self-test and protection functions, and blind charging and blind discharging are implemented. The same capacity is heavy, the c...
