Problems solved by technology

[0004] In practical applications, the temperature control and management of modules or battery packs composed of cells connected in series and parallel are generally carried out. At present, air cooling is generally used. Due to the low thermal conductivity of air, this method is inefficient and consumes a lot of energy.

Abstract

The invention provides a battery pack and an assembling method thereof. The battery pack comprises a battery pack shell and a plurality of battery cores arranged in the battery pack shell in an arraymanner, and further comprises a temperature control assembly and a battery system control assembly, wherein the temperature control assembly comprises a plurality of inner cooling fins, a semiconductor refrigeration sheet and outer cooling fins which are arranged in sequence, the two sides of the semiconductor refrigeration sheet abut against the inner cooling fins and the outer cooling fins respectively, the temperature control assembly further comprises a power supply assembly, the power supply assembly is communicated with the semiconductor refrigeration sheet to supply power to the semiconductor refrigeration sheet, the power supply assembly is communicated with the battery system control assembly, the battery pack further comprises a fan assembly, and the fan assembly is arranged on one side of the battery pack shell. The temperature in the battery core is regulated and controlled through the Peltier effect, so that the temperature control efficiency is high, heating and refrigerating can be switched at any time, and the battery pack has the advantages of short temperature control period, low energy consumption, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of battery pack temperature control management, in particular to a battery pack and an assembly method thereof. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] As a new type of clean energy, lithium batteries are widely used in energy storage power stations, pure electric vehicles, and communication backup power supplies; because lithium batteries have high requirements for the working environment temperature, too high or too low working environment temperature will affect the battery cell. The internal resistance, heat consumption rate, discharge capacity, cycle life, and state consistency all have a high impact. In addition, the geographical distribution of products in actual use is quite different, an...
