20 Dec 2002TL;DR: In this article, an electric traction vehicle is described which may be used to provide power to off-board electric power consuming systems or devices, such as electric power storage devices, which can be selectively discharged to allow the vehicle to be serviced.
Abstract: An electric traction vehicle is described herein which may be used to provide power to off-board electric power-consuming systems or devices. The electric traction vehicle may provide 250 kilowatts or more of three phase AC power to an off-board electric power consuming system. The electric traction vehicle may also include an electrical power storage device which can be selectively discharged to allow the vehicle to be serviced.

08 Nov 2002TL;DR: In this article, a portable device for electric power supply comprising of a power supply circuit (6, 16) and a battery (10) is described. But the battery is not connected to the power supply.
Abstract: The invention concerns a portable device for electric power supply comprising: connection means ( 8 ) for connecting an appliance ( 1 ) to be powered; and a power supply circuit ( 6; 16 ) supplying in output a supply voltage for the appliance when the circuit is selectively connected to a mains supply or to a low-voltage electric power source. It may also comprise a battery ( 10 ). In that case, the circuit ( 6, 16 ) can charge the power storage means when the circuit is connected to an appropriate electric power source, the connection means ensuring power supply to the appliance ( 1 ) from the power storage means ( 10 ).

TL;DR: An array of alternating anion and cation exchange membranes can be used to generate electric power from the free energy of mixing of river and sea waters, and a simple mathematical model is useful in exploring conditions for optimization.
Abstract: An array of alternating anion and cation exchange membranes can be used to generate electric power from the free energy of mixing of river and sea waters. A simple mathematical model, which predicts experimental results well, is useful in exploring conditions for optimization of the process. Major, but not impossible, improvements in technology would be required to bring the cost of power from the dialytic battery into line with foreseeable energy prices.
