A power supply device includes a battery 1, positive and negative-side contactors 3A and 3B, and a controller 10. The battery 1 supplies power to a load 20. The positive-side contactor 3A is serially connected to the positive side of the battery 1. The negative-side contactor 3B is serially connected to the negative side of the battery 1. The controller 10 determines whether the load 20 connected to the output sides of the positive-side contactor 3A and the negative-side contactor 3B is in a connected or non-contact state. The controller 10 includes a voltage detecting circuit 12 that detects the capacitor voltage of a capacitor 21 connected to the output sides of the positive-side contactor 3A and the negative-side contactor 3B, and a determination circuit 13 that compares the detected voltage with a predetermined voltage and determines the connected state of the load 20.

The method of controlling rechargeable battery power is a method that includes limiting the amount of usable power during rechargeable battery charging and discharging, determining a rechargeable battery current-voltage characteristic function based on rechargeable battery charging and discharging current flow and voltage, finding a limiting discharging current Imax and/or a limiting charging current Imin from a prescribed minimum voltage Vmin to prevent over-discharging and/or a prescribed maximum voltage Vmax to prevent over-charging and their intersection with the current-voltage characteristic function, and controlling current such that discharging current greater than or equal to Imax and/or charging current less than or equal to Imin does not flow through the rechargeable batteries. In this fashion, the amount of usable power can be limited considering factors such as the memory effect, and the rechargeable battery can be used to its maximum capability within the range of safe operation.

Related to a blast furnace coke and a production method thereof. A coke having high reactivity and high strength in which coke strength, reactivity with CO2 and a pore size distribution are each at a desired level can be produced at a low cost by using a coal blend composed of a small number of brands comprising a large quantity of caking coal having medium rank and low fluidity. The blast furnace coke, being obtained by charging a coal blend comprising 60 wt % or more of semi-heavy caking coal having medium rank and low fluidity in which a content of inert component is 30 vol % or more in total or another coal blend comprising 60 wt % to 95 wt % of semi-heavy caking coal having medium rank and low fluidity in which mean reflectance (Ro) is 0.9 to 1.1 and maximum fluidity (MF) is less than 3.0 and the balance being a caking coal in which mean reflectance (Ro) exceeds 1.1 into a coke oven and coking the coal blend, which has a pore size distribution where a content ratio of pores having a diameter of less than 10 μm is from 12 vol % to 15 vol % and a content ratio of pores having a diameter of from 10 μm to 100 μm is from 10 vol % to 15 vol % and the production method thereof.
