Abstract:

A temperature control system for an electrical storage battery () includes the battery and a vessel () adapted to contain a liquid (L). The vessel is in thermal communication with the battery. An ohmic heater includes electrodes () disposed within the vessel in contact with the liquid (L), and a controller () operative to apply different electrical potentials to different ones of the electrodes () so that an electrical current flows between the electrodes so as to heat the liquid and thus heat the battery. A temperature sensor () measures temperature of the battery, and the controller is responsive to the measured temperature of the battery to control the electric current and thereby control the heating.

International Classification:

H05B 3/00
H05B 3/03
F24H 1/20

Abstract:

An ohmic heater has a structure () defining a flow path extending in a downstream direction (D), a first pair of electrodes () and a second pair of electrodes (). The electrodes of each pair are adjacent one another in the downstream direction but spaced from one another in a direction perpendicular to the downstream direction; the pairs of electrodes are spaced apart from one another in the downstream direction. An electrical circuit () is operative to apply a voltage (i) between the electrodes () of the first pair; or (ii) between the electrodes () of the second pair; or (iii) between at least one electrode () of the first pair and at least one electrode () of the second pair, and may vary the applied voltage. The heater can meet varying conditions such as changes in conductivity of the liquid flowing through the heater.

International Classification:

A47G 19/12

Abstract:

A portable carafe has a reservoir () for holding a liquid, a hot liquid outlet () and a hot liquid flow path () connecting the reservoir to the hot liquid outlet. A heater () is arranged in the hot liquid flow path so that the heater can heat liquid passing from the reservoir () to the hot liquid outlet (). The heater () may be inactive when no liquid is passing through the hot liquid flow path, and may be active only when hot liquid is to be dispensed. The carafe may include a battery () for powering the heater. The carafe may include a cold liquid outlet () and a cold liquid flow path (), and may be arranged so that tilting the carafe in one direction causes hot liquid to be dispensed, whereas tilting the carafe in another direction causes cold liquid to be dispensed.
