Abstract:
The invention relates to a method for improving the performance of a traction battery during a start-driving phase of an electric vehicle. A start-driving point is established at which the start-driving phase begins. A temperature of the traction battery is sensed. The temperature is compared with a minimum operating temperature, and the traction battery is heated if the comparison indicates that the temperature of the traction battery is below the minimum operating temperature. For the heating process, the temperature increases such that a temperature of the traction battery at the start-driving point is at least equal to the minimum operating temperature.
Abstract:
Battery charging control methods, electrical vehicle charging methods, battery charging control apparatus, and electrical vehicles are described. In one arrangement, battery charging control methods include accessing price information for electrical energy supplied by an electrical power distribution system and controlling an adjustment of an amount of the electrical energy from the electrical power distribution system used to charge a rechargeable battery at different moments in time using the price information. Other arrangements are described.
Abstract:
The present invention relates to a distribution network comprising electric wires (5) for distribution of electric current, a plurality of tap-off facilities (6) with at least one socket means (9) for tapping off electric current to optional power-consuming units (1), and a central computer unit (10) communicating with the individual tap-off facilities. At least some tap-off facilities (6) in the network comprise a switch (13) and a regulating device (11) with a microprocessor (21), a user connecting a power-consuming unit (1) to one of said tap-off facilities being identifiable to the central computer unit (10) or to the regulating device (11) via a microprocessor in the power-consuming unit, and the regulating device, in case of accepted identification, keeping the switch (13) closed and permitting tap-off of electric current from the socket means (9), whereas, in case of non-accepted identification, the regulating device keeps the switch open and prevents tap-off of electric current from the socket means (9). The invention also relates to a device and a method for respectively permitting and preventing current supply from the network.
Abstract:
The invention relates to an installation (10) for returning energy to an item of equipment, comprising at least one photovoltaic cell (20A-20D; 22A-22B), at least one energy provision device (12) comprising means of electrical connection (14), at least one energy storage assembly (18A, 18B), linked on the one hand to at least one of the photovoltaic cells and on the other hand to at least one of the energy provision devices so as to provide it with the electrical energy, and an inverter (28, 30) interposed between at least one of the energy storage assemblies and at least one of the energy provision devices, so that the electricity transmitted to the provision device is in the form of alternating current. The invention also relates to a charging module comprising at least one energy storage assembly and at least one inverter.
Abstract:
The present invention concerns a method and a device for controlling the voltage of a catenary supplying electric power to rolling stocks. The first rolling stock: - detects a traction command or a regeneration command of a second rolling stock in the neighborhood of first rolling stock, - increases the electric power supplied by the first rolling stock to means for heating, ventilation and air conditioning when a regeneration command of the second rolling stock is detected, - decreases the electric power supplied by the first rolling stock to the means for heating, ventilation and air conditioning when a traction command of the second rolling stock is detected.
