Abstract

The invention discloses a low-energy-consumption thermoelectric power generation battery heat dissipation and preservation system and an application, and the system comprises a cooling pipe where a cooling medium flows, wherein the cooling pipe wraps the outer side of a battery monomer of a power battery pack; a heating device which is arranged between the battery cells of the power battery pack;phase change heat storage devices which are arranged at the two sides of the battery cells of the power battery pack; a thermoelectric power generation device which comprises a cold-end thermoelectricpower generation sheet and a hot-end thermoelectric power generation sheet which are connected in series, wherein the hot-end thermoelectric power generation sheet is arranged at the upper end of thepower battery pack, the cold-end thermoelectric power generation sheet is arranged on the outer side of the cooling pipe, so the power is generated through the temperature difference between the cold-end thermoelectric power generation sheet and the hot-end thermoelectric power generation sheet.

Description

technical field [0001] The present disclosure relates to the technical field of power battery thermal management, in particular to a heat dissipation and heat preservation system for a power battery that uses temperature difference to generate electricity with low energy consumption, which can be applied to various vehicle bodies, especially new energy vehicles. Background technique [0002] Power batteries are an important part of new energy vehicles. The operating temperature of the battery is the main parameter affecting its operating performance and life. According to experimental research, when the ambient temperature of the battery pack is too low or too high, the service life of the battery is affected. In addition, when the battery works under low temperature conditions, the chargeable capacity and dischargeable capacity of the battery decrease, which directly affects the cruising range of the power battery, and the discharge voltage of the battery decreases under l...
