Abstract:
A battery case within which a battery is housed includes a first layer that is made of metal, a second layer that is made of heat insulating material, and a third layer that is made of phase-change heat storage material. The second layer is closer to the battery than the first layer is. The third layer is closer to the battery than the second layer is.

An electrochemical cell is provided. The electrochemical cell includes, but is not limited to, a can, a cell element within the can, electrolyte within the can, and a first suppressant container including suppressant and disposed within a void defined within the can. The suppressant is separated from the electrolyte by the first suppressant container.
Abstract:
Es wird ein Batteriemodul einen Batteriezellenstapel (10) aus mindestens zwei Batteriezellen (11) aufweisend beschrieben, bei dem jede Batteriezelle (11) von zumindest einer PCM-haltigen Zelle (12) kontaktiert wird, die in den Batteriezellenstapel (10) eingefügt ist. Dadurch ist die thermische Weglänge zwischen jedem PCM-Molekül und der Batterie sehr gering, wodurch eine verbesserte passive Klimatisierung der Batteriezellen erreicht wird. Ferner wird eine Ausgestaltung des Batteriemoduls als Lithium-Ionen-Akkumulator und ein Kraftfahrzeug vorgeschlagen.
Abstract:
A method is described for monitoring a charging process of a battery (20), in which cell voltages of a plurality of battery cells (21) are measured (S11) at regular time intervals, and loading of the battery (20) by a process of switching on an additional electrical load is prevented (S16) if the measured cell voltage of one battery cell (21) exceeds (S14) a predetermined cell voltage threshold value. A motor vehicle is also proposed, which is designed to carry out the method according to the invention during a battery charging process. In addition, a battery system is described, in which a controller (25) is designed to determine an estimated value as a function of measured battery parameters during a charging process of the battery (20), which estimated value corresponds to the maximum temperature in the battery (20) if the charging process is continued without interruption.
Abstract:
A vehicle battery temperature control system includes a battery (14), a housing (16), a heat exchanger (18) and a sensor (32). The battery (14) has a heat sink (20). The housing (16) has a chamber (24) that contains the battery (14) and saturated liquid coolant (26) that substantially immerses the heat sink (20) to receive the thermal energy to cause a phase change of the coolant (26) from a liquid to a vapor. The heat exchanger (18) removes thermal energy from the vapor to change the vapor to liquid, and returns the liquid to the chamber (24). Either a valve (38, 40) selectively conveying coolant (26) between the chamber (24) to an air-conditioning system or a heating device (52) is controlled based on a characteristic of the coolant (26) detected by the sensor (32) to remove or provide thermal energy to or from the coolant (26) based on a relationship between the characteristic of the coolant (26) and a threshold.
Abstract:
A cooling system is used to cool heat-producing devices, such as ultra-capacitor cells. The cooling system includes tubing through which a cooling fluid is circulated. Cold plates are mechanically coupled to the tubing, and a spring plate is used to press the cold plates against the objects to be cooled. The spring plate is able to flex, to allow the cold plates to be positioned to engage objects of different heights. The tubing is serpentine tubing that also allows flexure, for positioning of the cold plates. The objects to be cooled may be bus bars coupling together cylindrical energy-producing devices. The cold plates may be made of a thermally-conductive material that is electrically insulated from the bus bars. The system may be a two-phase flow system in which some of the cooling fluid is vaporized as it receives heat from the cold plates.
