Title: RAIL VEHICLE SYSTEM
Abstract:
An electronic locomotive (50) is provided with a first control line (3f) that is laid between couplers (2c and 2d), DC buses (3c and 3d), a power storage device (61) that is connected to the DC buses (3c and 3d), and a DC/DC converter (60) that performs a charge and discharge control with respect to the power storage device (61). A non-powered vehicle (1) is provided with DC buses (3a and 3b) that are connected to the DC buses (3c and 3d) via a coupler (2a), a second control line (3e), a power storage device (12) that is connected to the DC buses (3a and 3b) via a breaker (5), and a BMU (8) that manages the power storage device (12). The DC/DC converter (60) performs a power storage control with respect to the power storage device (61) and a power storage control with respect to the power storage device (12). In a case where an abnormality is determined in the power storage device (12), the BMU (8) controls the breaker (5) to be turned off and disconnect electrical connection between the power storage device (12) and the DC buses (3a and 3b).
