Abstract: The battery charging apparatus has an auxiliary battery 1, a first charging circuit 20 for charging the auxiliary battery 1 with a first charging current derived from an externally connected commercial power source AC, and a second charging circuit 30 for charging the load battery LB with a second charging current that is higher than the first charging current and is derived from power from the auxiliary battery 1, which is charged by the first charging circuit 20. The first charging circuit 20 is connected to allow power supply to the auxiliary battery 1 and the second charging circuit 30. This makes charging circuit switching unnecessary and eliminates the need for components such as high-power switching devices. The charging apparatus has the positive features that stability and reliability are improved, and the load battery can be charged with the auxiliary battery 1 in a shorter time than using commercial power.

Abstract: A nonaqueous electrolyte battery comprising a positive electrode, a negative electrode having lithium as an active material, a nonaqueous electrolyte comprising a solute and a solvent, and a separator. The solvent is a mixed solvent consisting essentially of 5 to 50% by volume of cyclic carbonate, 5 to 50% by volume of chain carbonate and 40 to 80% by volume of ether. The mixed solvent of a specific composition is less likely to cause undesirable surface layer formation on the negative electrode so that the electric resistance of the interface between the negative electrode and nonaqueous electrolyte is kept small. The nonaqueous electrolyte battery of the invention can therefore deliver a large amount of current and provide a high discharge capacity at low temperatures.
