Title:
TECHNIQUE FOR HEATING TRACTION ENERGY STORAGE UNIT
Document Type and Number:
Japanese Patent JP2020004715
Kind Code:
A
Abstract:
To provide a technique for minimizing exergy losses in temperature management circuits of a traction energy storage unit.SOLUTION: A traction energy storage unit 100 for the storage of electrical energy in a motor vehicle that is propelled or propellable by means of stored energy includes at least one pressure-resistant sealed heat pipe 106 configured for the passive transmission of heat, using heat of vaporization, from a heat-absorbing end 108 of the heat pipe to a heat-emitting end 110 of the heat pipe, the heat-emitting end being spaced from the heat-absorbing end. The heat-emitting end 110 constitutes part of a cell wall 104 or projects through the cell wall into the respective secondary cell 102. The energy storage unit 100 further includes at least one heat source 118, which is arranged outside the at least one secondary cell 102 and is in direct contact with the heat-absorbing end 108.SELECTED DRAWING: Figure 2
