An omni directional, vertical discharge wind turbine, consisting of a shroud that captures wind from any direction and directs it to flow vertically through a throat section where an aerofoil multi-bladed rotor is mounted. The rotor shaft is connected to an electrical power generator. The intake of the shroud incorporates multiple horizontally curved blades of toroidal form varying up to nearly twice the size of the rotor diameter, stacked, staggered and secured in place by multiple aerodynamic vertical walls in the radial direction, to form a central collection chamber for wind. The blade curving angles and the stacking arrangement are such that while accelerating and focusing the wind, across the full swept area of the rotor blades, the loss of air from the central collection chamber is significantly reduced by air flow forming a fluid dynamic gate across inactive faces. Utilizing a wedge and collar near the open top discharge the free wind stream flowing across the open top assists in increasing the flow of air through the rotor. With the increased extraction and wider operational envelop, the energy produced per annum of this omni-directional shrouded vertical wind turbine is anticipated to be much higher than that of a standard free wind turbine of same rotor diameter.

A method for detecting a state of charge (SOC) of a battery is disclosed. The method includes inputting a pulse to the battery for receiving a response curve of the battery associated with the pulse inputted to the battery, determining a set of parameters for preparing a simulated curve, comparing a difference between the response curve and the simulated curve, determining whether the difference between the simulated curve and the response curve is less than a predetermined threshold before further utilizing the parameters to determine the SOC from a corresponding relationship.

Line interconnecting means interconnecting two lines adjacent to each other laterally thereof comprises a lateral projection 64b formed on a two-way connecting block coupling 64 of the first of the lines, a recessed portion 54c formed in a two-way connecting block coupling 64 of the second of the lines for the lateral projection 64b to fit in, a coupling branch channel 82 formed in the block coupling 64 provided with the lateral projection, a first valve body branch channel 90A formed in the body 54a of a shut-off valve 54 of the first line for always causing a main channel 89 in the valve body to communicate with the coupling body upper surface opening 82a of the coupling branch channel 82, and a second valve body branch channel 90B formed in the body 54a of a shut-off valve 54 of the second line for always causing a main channel 89 in the valve body to communicate with a lateral projection upper surface opening of the coupling branch channel 82.
