Abstract: A gasifier energy production device including: a gasifier device including a fuel inlet, an air inlet, and a fuel gas outlet; a heat engine including an air inlet, a fuel gas inlet, and an exhaust gases outlet; a battery; an electrical current generator, the heat engine is coupled to at least the electrical current generator and the electrical generator is coupled to the battery; and a controller such that all fuel gas produced by the gasifier device once the gasifier device produces sufficient gas to make the heat engine operate and until the heat engine has stopped is injected into the engine such that energy required at an output from the energy production device is independent of the production of fuel gas.

Abstract: A battery is provided. The battery includes a plurality of electrochemical cells connected in series with each other and adapted for each generating an electric current from an oxidation-reduction reaction between an oxidizing fluid and a reducing fluid. The battery also includes, for each electrochemical cell, a control device for controlling the voltage across the terminals of the cell. The battery also includes a voltage regulator device electrically connected to the cell so that the control device measures the voltage across the terminals of the cell, increased by an offset voltage across the terminals of the regulator device.
