(54) Battery equipment of railway vehicle and railway vehicle


(57) When battery equipment is applied to a drive system of a railway vehicle, a high voltage needs to be produced and the safety during assembly needs to be secured, and therefore the battery equipment needs to be downsized so as to be mounted in a limited space of the railway vehicle. The present invention provides battery equipment for a railway vehicle including a plurality of battery modules 11, each of which stores a plurality of lithium-ion cells, a battery module storage section 1 that stores the plurality of battery modules, a control section 2 that detects conditions of the plurality of battery modules and controls charge and discharge thereof and a case 3 that allows the battery module storage section and the control section to be juxtaposed in a traveling direction of the vehicle.
