The invention relates to a railway vehicle battery capacity management system which is used for distributed management on a storage battery pack. The storage battery pack comprises single batteries; the management system comprises a battery sampling box, a voltage sensor, a current hall sensor and a temperature sensor which are connected with the battery pack as well as a battery management systemcontroller connected with the battery sampling box, wherein the voltage sensor, the current hall sensor and the temperature sensor are connected with the battery management system controller; the battery management system controller is used for supplying power to the sampling box and the current hall sensor and receiving data of the battery sampling box, the voltage sensor, the current hall sensor and the temperature sensor; the system also comprises a ground server connected with the battery management system controller and used for acquiring surplus capacity of the storage battery pack. Thesurplus capacity of the batteries can be estimated and is ensured to be maintained in the normal work range.
Description
Technical field [0001] The invention relates to the field of rail vehicle power management, in particular to a rail vehicle battery capacity management system and a rail vehicle battery capacity management method. Background technique [0002] The on-board battery and its management system occupy a very important position in vehicle management. Effective use and management of the energy of the vehicle battery and extending the service life of the vehicle battery are an important part of the research on the vehicle battery capacity management system. There are individual differences between the single batteries, and the uncertainty of the vehicle's operating state during use, resulting in inconsistent performance of the single batteries. Summary of the invention [0003] In view of this, an embodiment of the present invention provides a rail vehicle battery capacity management system for distributed management of battery packs. The battery packs include single cells, and the singl...
