A temperature management system for an energy storage system, a motor vehicle including such a temperature management system, a use of a hygroscopic material in such a temperature management system and a manufacturing method of such a temperature management system. The temperature management system includes at least one energy storage module, a carrier element and a cooling element. The cooling element includes a first surface directed to an environment of the energy storage module and a second surface opposite to the first surface. The carrier element is arranged between the second surface of the cooling element and the energy storage module and configured to transfer heat from the energy storage module in direction to the environment. The cooling element includes at least one humidity absorbent material to increase a heat capacity of the cooling element.

Temperature management system

A battery module () including a plurality of heat pipes () configured to be thermally connected to a heat reservoir (), the heat pipes being individually sealed and integrated in an external surface (B) of the battery module. The heat pipes are configured to be arranged in physical contact with a heat conducting element (A) for transferring heat to and/or from the battery module.

Battery module

The disclosure relates to a temperature management system for an energy system of a motor vehicle. The temperature management system includes an energy storage system, a conductivity element, and an ambient interface. The ambient interface includes a first surface directed to an environment of the energy system and a second surface opposite to the first surface. The conductivity element is arranged between the second surface of the ambient interface and the energy storage system. The conductivity element is switchable between an isolating mode with a first lower thermal conductivity and a conductive mode with a second higher thermal conductivity. The conductivity element includes a voltage sensitive material. The voltage sensitive material is switchable between the first and the second thermal conductivity depending on an applied voltage. The voltage sensitive material includes a piezoelectric material.

Temperature management system for an energy system of a motor vehicle

A method for controlling cooling of a traction battery in an electric vehicle where the method comprises determining a battery temperature profile for a segment of a planned route based on route information describing a route from a starting point to a destination and based on a current battery status and determining a battery cooling profile for the segment of the route based on the battery temperature profile. By means of the route information and the state of the battery, the battery cooling profile can be determined in order to minimize the power required for cooling the battery. Since the route information can provide information relating to a range of parameters which influence the power consumption along the route, the cooling needs of the battery can also be estimated for the route as a whole.
