Abstract

The present invention relates to a heat management assembly for a battery module, a battery module including the heat management assembly, and a vehicle including the battery module. The thermal management assembly includes: a heat conduction element, which is suitable for being arranged inside the battery module and directly contacts with the cells of the battery module; on the housing, and lean against the heat-conducting member; the heat dissipation fins, the heat dissipation fins are fixed on the fixed base plate by means of at least one fixing component; and the Peltier device, the Peltier device is arranged on the fixed base plate Between the cooling fins for cooling / heating the cell. This thermal management component integrates the cooling, heating and constant temperature functions required by the battery module, without the risk of coolant leakage, can reduce the weight of the battery module, and solve the problem of large temperature difference between the upper and lower sides when the battery is cooled / heated. Thus, the temperature of the battery module is controlled within an optimal range.

Description

technical field [0001] The present invention relates to the technical field of thermal management of battery modules, and more particularly, the present invention relates to a thermal management component for battery modules. The invention also relates to a battery module comprising such a thermal management assembly, and to a vehicle, in particular an electric vehicle or a hybrid vehicle, comprising such a battery module. Background technique [0002] In order to improve the safety of the thermal management system of the battery module (especially the power battery module of the electric vehicle or hybrid vehicle), and ensure the heat dissipation efficiency and the accuracy of temperature regulation, it is known that the Peltier device can be used to achieve Thermal management of battery modules. [0003] Document CN106549197A discloses a temperature control method of a battery module implemented by means of a Peltier device. This method keeps the temperature difference in...
