Abstract
An electric locomotive includes a first control line and DC buses laid between couplers, a power storage device connected to the DC buses, and a DC/DC converter that executes charge and discharge control with respect to the power storage device. A non-powered vehicle includes DC buses connected to the DC buses via a coupler, a second control line, a power storage device connected to the DC buses via a circuit breaker, and a BMU that manages the power storage device. The DC/DC converter executes power accumulation control with respect to the power storage device and power accumulation control with respect to the power storage device. When having determined abnormality of the power storage device, the BMU controls the circuit breaker to be turned off, thereby cutting off electrical connection between the power storage device and the DC buses.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
