    Abstract: To provide a light-emitting element with high emission efficiency or long lifetime, in which the use amount of a phosphorescent compound is small. To provide a light-emitting element including a light-emitting layer between a pair of electrodes, wherein the light-emitting layer includes a phosphorescent compound, a first organic compound, and a second organic compound, and the combination of the first organic compound and the second organic compound forms an exciplex. The light-emitting element transfers energy by utilizing the overlap between the emission spectrum of the exciplex and the absorption spectrum of the phosphorescent compound and thus has high energy transfer efficiency, even when the concentration of the phosphorescent compound is low.

    Abstract: A control system for a secondary battery which is less affected by the ambient temperature by performing temperature control of the secondary battery is provided. A control system for a secondary battery which is less affected by the ambient temperature and in which a plurality of kinds of secondary batteries are used for temperature control is achieved and mounted on a vehicle. Specifically, when the ambient temperature is low, some of second secondary batteries are heated by self-heating of a first secondary battery. After the second secondary batteries are sufficiently heated, the rest of the second secondary batteries are heated in stages by self-heating of the some of the second secondary batteries whose temperature has been increased. Whether the some or all of the second secondary batteries are sufficiently heated can be confirmed if the temperatures of a plurality of temperature sensors provided in the second secondary batteries are within the operating temperature range of the second secondary batteries. For example, with the use of a temperature sensing terminal (T terminal) for a temperature sensor, a switch is closed when the internal temperature of the secondary batteries is out of the operating temperature range.
