A battery system includes a plurality of battery cells and a temperature-control element that is thermally conductively connected to the battery cells via a temperature-control surface. The temperature-control element has a temperature-control channel in an interior of the temperature-control element. The temperature-control channel is routed on the forward flow side via an inlet and on the return flow side via an outlet from the temperature-control element. A bypass is connected to the temperature-control channel via a dividing node and a merging node with the dividing node being arranged closer to the inlet than the merging node. A motor vehicle includes the battery system.

Battery system with a temperature-control element containing a temperature-control channel and a bypass and motor vehicle containing the battery system

A battery module () having a number of electrically interconnected battery cells (), wherein the individual battery cells () are temperature-controlled by means of a temperature control fluid (). Between the battery cells (), there extends a duct system () through which the temperature control fluid () flows. The duct system () is separated completely from a degassing system () of the battery cells ().

Battery pack with air-type cooling

A lithium-ion battery cell includes a housing with an electrode arrangement and a temperature sensor that is arranged in the interior of the housing. The temperature sensor has an electro-thermal oscillator that converts a temperature into a frequency. A motor vehicle includes the lithium-ion battery cell.

Battery cell having a temperature sensor which is integrated in the battery cell housing

A battery includes at least one battery cell that has a housing with an electrode arrangement arranged therein. A first temperature sensor is arranged outside the battery cell housing, and a second temperature sensor is arranged inside the battery cell housing. The temperature dynamic of the second temperature sensor is higher than the temperature dynamic of the first temperature sensor. A motor vehicle includes the battery cell.

Battery comprising a battery cell with an external and an integrated temperature sensor, and a method for operating said battery

A method for controlling the temperature of at least one battery element, a battery, and a motor vehicle that has the battery includes specifying a temperature value, and determining the cool-down behavior of the at least one battery element beginning at a first temperature. A first point in time, at which the battery temperature will have reached or fallen below the temperature value, is determined by evaluating the cool-down behavior. Subsequently, a second point in time for a beginning of the charging or discharging of the at least one battery element is determined. If tmin&#x3c;t_end, heat is applied to the at least one battery element in such a manner that the battery temperature at the second point in time is higher than or equal to the temperature value. The method can be used to avoid damage to the battery element during charging and discharging of the battery element.

Method for controlling the temperature of at least one battery element, battery and motor vehicle with such a battery

A temperature control method and a battery system create an optimal temperature range for operating a battery. The battery cells of the battery lie in several separate modules that are integrated in a temperature control circuit. Heat is increased stepwise in a heating phase in which only one first module is heated by means of a temperature control medium, the medium being active in the temperature control circuit and being heated by means of a heating element. The heat that is generated during the operation of at least the first module is used to heat at least one further module.

Temperature control method and battery system

A devices for pumping fuel has at least one suction jet pump and a drive line, supplying the suction jet pump with fuel, that branches off from a pressure line leading to an internal combustion engine and that can be blocked off by means of a shutoff valve. By means of a shutoff valve, it is possible to switch off the suction jet pumps. The pressure of the pressure line acts on the shutoff valve in such a way that the shutoff valve closes at a pressure that is greater than or equal to a predetermined closing pressure.
