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 device for the temperature control of battery cells in a battery, particularly a battery configured as an energy source for the drive of hybrid, plug-in hybrid, or electric vehicles includes a contact surface for thermally contacting the battery cells with the device. The contact surface is configured such that the battery cells to be temperature-controlled are arranged on the contact surface. The device has elements below the contact surface that are elastically restoring such that, when a compressive load acting orthogonally to the contact surface is applied, the contact surface is lowered in the region of the applied compressive load. A restoring force acts against the compressive load.

Elastic device for the temperature control of battery cells

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 battery system includes a plurality of battery cells connected to one another and includes an apparatus configured to control the temperature of the plurality of battery cells. The apparatus includes at least one hollow body through which a coolant flows and includes at least one heat conducting element having at least one first contact region and at least one second contact region. The at least one first contact region has a planar configuration and is in thermal contact with a side face of at least one battery cell of the plurality of battery cells. The at least one second contact region is arranged on the at least one hollow body such that the at least one second contact region is in thermal contact with the at least one hollow body.

Battery system having battery cells and an apparatus for controlling the temperature of the battery cells

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.
