    Abstract: A vehicle configured to perform external charging for charging an in-vehicle power storage device using electric power supplied from a system power supply outside the vehicle, wherein the vehicle includes a control device and a storage device. The control device is configured to set a command value of a charging current supplied from the system power supply to the power storage device through the charging device during the external charging, and to control the charging current by transmitting the command value to the charging device. The storage device is configured to store a program executed by the control device. The control device calculates an integrated value of the command value when the command value is larger than a threshold value. The control device is configured to execute a reduction process of reducing the command value when the integrated value is large than when the integrated value is small.

    Abstract: A method for generating smoke in a cell pack by which a very small amount of smoke can be generated from a specific single unit cell among unit cells constituting the cell pack. The method causes smoke generation in a cell pack in which unit cells are connected and which includes a positive electrode output terminal for electrically connecting the positive electrode terminal of the unit cell and an external device, and a negative electrode output terminal for electrically connecting the negative electrode terminal of the unit cell and an external device. By attaching a heating means to the negative electrode output terminal, the electrode body of a specific single unit cell is heated through the negative electrode output terminal to which the heating means is attached. As a result, it is possible to cause the generation of a small amount of smoke from the specific single unit cell.

    Abstract: A cell that is a non-aqueous electrolyte secondary battery includes an electrode body in which a sheet-shaped positive electrode and a sheet-shaped negative electrode are stacked via a separator, and a battery case that accommodates the electrode body and an electrolytic solution. The electrode body includes a predetermined number of outer layers including an outermost layer made up of the separator and the negative electrode disposed on an outermost side of the electrode body, and an inner layer disposed on an inner side than the outer layer. The outer layer includes a negative electrode mixture layer configured to suppress heat generation of the electrode body caused by a short circuit of the electrode body as a heat generation suppressing member. The inner layer does not include the heat generation suppressing member.
