摘要:
The present invention relates to a method for controlling power transfer from a grid to a rechargeable energy storage system, RESS, and/or an auxiliary load of the vehicle, via at least one intermediate power transfer component. The method comprises: - providing predicted operational information of the vehicle, the predicted operational information comprising a connected time period in which the vehicle is connected to the grid, - providing component data comprising power transfer characteristic of the intermediate power transfer component, the component data including at least the critical temperature limit of the intermediate power transfer component, - transferring power from the grid to the RESS and/or from the grid to the auxiliary load of the vehicle according to a power transfer model, such that the temperature of the intermediate power transfer component is kept at least below the critical temperature limit.

An object of the present invention is to provide a battery temperature adjustment apparatus that suppresses performance deterioration and degradation of a battery and at the same time, suppresses reduction in cruisible distance of an electric vehicle. Control unit (40) controls an operation of vehicular air conditioner (10) such that the temperature of battery (5) falls in a predetermined temperature range, based on battery temperature (Tb). In this case, control unit (40) changes an operating condition or an operating state of vehicular air conditioner (10) according to whether or not an external power source to supply power to battery (5) is present.

A flexible energy management system is disclosed, which can be applied to trains having a wide variety of formations. The invention uses a special recycling vehicle incorporating regenerative braking and energy storage such as a battery, together with a power conversion system to supply electricity in the standard form for train services such as lighting and air conditioning. A control system arranges the supply of electricity for train services to coaches from either the recycling vehicle or the locomotive depending on the level of charge in the battery. This improves the overall energy efficiency of the train without requiring special electrical bus connections between vehicles. Further embodiments of the system include facilities for boost traction and shunting, with arrangements for the automatic control of power distribution when train formations are changed, as illustrated in Figure 5.
