The present disclosure relates to a portable safety terminal based method for processing rail transit resources, and a system for the method. The method includes: in a degradation mode, performing interaction between a portable safety terminal and a wayside controller; providing a driver with safety display of an environment where a train is located, and obtaining a location of the train and information of a relationship between a front train and a rear train; and providing the driver with a means to apply for line resources, such that the driver can, according to the train environment, autonomously apply for the line resources, and release the resources for use by subsequent trains after driving the train to pass through a zone. Compared to the prior art, the present disclosure has the advantages of improving the safety of train driving and field maintenance operation, etc.

A management method for an electric vehicle charging station system. The charging station system includes: several charging stations, each equipped with several charging terminals and one local manager able to pilot the charging terminals; and a main manager able to drive the charging stations. The method includes: the local manager of each charging station getting information associated with vehicles connected to the charging terminals and determining an optimization proposal for electric energy transfer at the level of the charging station; the main manager allocating electric power each charging station on the basis of the optimization proposals; and the local manager of each charging station driving charging terminals based on the allocated power.

A method and to a device for ascertaining a state of health of a battery for a transportation device. The method includes: charging the battery until a predefined target voltage is reached in a first charging phase of the battery, ascertaining a first voltage value of the battery at a first predefined point in time after the predefined target voltage has been reached in a relaxation phase of the battery, ascertaining a second voltage value of the battery at a second predefined point in time, deviating from the first predefined point in time, in the relaxation phase of the battery, ascertaining a piece of information about the state of health of the battery based on a change of the second voltage value with respect to the first voltage value, and using the piece of information in the transportation device and/or in an external server.

A battery pack for efficiently supplying a power to a vehicle and including a battery assembly, a power supply terminal connectable to a connection terminal of the vehicle that is connected to a vehicle control unit and a vehicle motor, a power supply path located between the power supply terminal and the battery cell and supplying a power from the battery cell to the power supply terminal, a switching unit provided on the power supply path electrically turn on/off the power supply path, a mounting recognition unit recognizing whether the battery pack is mounted to the vehicle, and a processor controlling the switching unit so that a power is supplied from the battery cell to the vehicle control unit, when receiving a signal from the mounting recognition unit that the battery pack is recognized as being mounted to the vehicle.

A computer implemented method for managing charge availability of a charge unit (CU) to obtain charge for a battery of an electric vehicle (EV) is provided. The CU includes a computer for processing at least part of the method and for communicating with a server over a network. The method includes receiving, by the server, status information from the computer of the CU. The method includes sending to the computer of the CU instructions to make a reservation for the CU.
