Abstract

The invention provides a power battery pack with a heat superconducting heat exchanger and a power battery pack system. The power battery pack comprises a heat superconducting heat exchanger and a plurality of battery cells, wherein the heat superconducting heat exchanger comprises a heat radiator, a heater and a plurality of heat superconducting plates arranged at intervals in parallel; the heater is positioned on one side of the heat radiator; the heat superconducting plates are positioned between the heat radiator and the heater, a heat superconducting pipeline is formed inside each heat superconducting plate, each heat superconducting pipeline is a closed pipeline, and each heat superconducting pipeline is filled with a heat transfer medium; the battery cells are positioned between theheat radiator and the heater, and each battery cell is in contact with the corresponding heat superconducting plate. According to the power battery pack, the battery cells can be quickly heated whenthe temperatures of the battery cells are relatively low, so that the heating starting time of the battery cells in cold conditions is improved; and simultaneously, quick heat radiation and cooling can also be carried out on the battery cells when the temperatures of the battery cells are relatively high.

Description

technical field [0001] The invention belongs to the technical field of semiconductor manufacturing, and in particular relates to a power battery pack with a thermal superconducting heat exchanger and a power battery pack system. Background technique [0002] With the development of the times, there has been a wave of new energy vehicles (electric vehicles) around the world, and it has also accelerated the pace of electric vehicles replacing traditional fuel vehicles. The core component is the power battery. The core part of the new energy electric vehicle is composed of one or more power battery packs, and the power battery pack is densely arranged with multiple battery cells. When the electric vehicle continues to run under heavy load conditions, the power battery will continue to In the high rate discharge state. At this time, a large amount of heat is rapidly generated in the battery pack, and the central area inevitably accumulates more heat, while the edge area is les...
