    摘要： A control apparatus for a vehicle cooling apparatus that includes: a PCU cooling unit for cooling a power control unit controlling an electric motor; a T/A cooling unit for cooling a drive-force transmitting apparatus including the electric motor; and a heat exchanger for transferring heat between the PCU cooling unit and the T/A cooling unit. The T/A cooling unit includes a first pump for circulating a refrigerant of the T/A cooling unit, while the PCU cooling unit includes a second pump for circulating a refrigerant of the PCU cooling unit. The control apparatus includes a controlling portion configured to cause the first pump to be driven when a temperature of the power control unit is higher than a threshold temperature value and a temperature of the refrigerant of the PCU cooling unit is higher than a temperature of the refrigerant of the T/A cooling unit.

    摘要： A nonaqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a separator. The positive electrode includes a positive electrode current collector, a first positive electrode mixture layer that is provided on the positive electrode current collector, and a second positive electrode mixture layer that is provided on the first positive electrode mixture layer. The first positive electrode mixture layer includes a first positive electrode active material and a first conductive material. The second positive electrode mixture layer includes a second positive electrode active material and a second conductive material. The first positive electrode active material includes a lithium composite oxide having a layered crystal structure. The second positive electrode active material includes a lithium composite phosphate having an olivine-type crystal structure. The second conductive material includes a conductive material having a higher crushing strength than the lithium composite phosphate having an olivine-type crystal structure.

    摘要： A secondary battery includes a wound electrode assembly in which a positive electrode sheet, a negative electrode sheet and a separator are stacked and wound. The positive electrode sheet is provided with a long positive electrode current collector and a positive electrode active material layer. The positive electrode active material layer is disposed on the positive electrode current collector. The negative electrode sheet is provided with a long negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer is disposed on the negative electrode current collector. The separator is interposed between the positive electrode sheet and the negative electrode sheet. The negative electrode current collector has a first active material layer-free region at one edge of the negative electrode current collector in a winding direction of an axis of the wound electrode assembly. The first active material layer-free region is a region where the negative electrode active material layer is not formed. The positive electrode current collector has a second active material layer-free region at one edge of the positive electrode current collector in a winding direction of an axis of the wound electrode assembly. The second active material layer-free region is a region where the positive electrode active material layer is not formed. The negative electrode current collector and the positive electrode current collector are disposed, with the first active material layer-free region and the second active material layer-free region being projected toward opposite sides in the winding direction of the axis of the wound electrode assembly. A width of the negative electrode active material layer is wider than a width of the positive electrode active material layer and a bacterial cellulose is disposed in at least a surface layer of the negative electrode active material layer that faces the second active material layer-free region.
