Detailed explanation of LR03 alkaline battery thermal management system design
As the main energy storage device for loading battery packs on electric vehicles, the battery pack is a key component of hybrid/electric vehicles, and its performance directly affects the performance of hybrid/electric vehicles. At present, batteries generally have shortcomings such as low specific energy and specific power, short cycle life, and performance greatly affected by temperature. Due to the limited space in the vehicle, the accumulation of heat generated during battery operation will cause uneven temperatures everywhere and affect the consistency of the battery cells. This will reduce the battery charge and discharge cycle efficiency, affect the battery's power and energy performance, and in severe cases will lead to thermal runaway, affecting system safety and reliability. In order to maximize the performance and life of the battery pack, the battery needs to be thermally managed to control the battery pack temperature within a reasonable range.
The main functions of battery thermal management include: accurate measurement and monitoring of battery temperature; effective heat dissipation when the battery pack temperature is too high; rapid heating under low temperature conditions; ensuring the uniform distribution of the battery pack temperature field; and the coordination between the battery cooling system and other heat dissipation units. match.
There are two ways to cool the battery pack: air cooling and liquid cooling. Research shows that the air cooling method is easy to implement, but the temperature gradient of the battery pack changes greatly, which is not conducive to the stable operation of the battery. Liquid cooling, which uses coolant to exchange heat with the refrigerant of the air conditioning system, has gradually become mainstream. Scientific management of battery thermal issues in new energy vehicles requires consideration of the interaction of multiple systems. The influence relationship between various systems is shown in Figure 1. There are varying degrees of coupling between battery pack cooling and automobile air conditioning systems, motor cooling systems, engine cooling systems and other systems. In this way, when making battery system temperature control strategies and thermal management, it is necessary to analyze the impact on other systems at the same time.
solution
In order to solve the complex coupling relationship between fluid systems in battery thermal management, the evaporation cycle library, liquid cooling library, battery library, etc. of Dymola software can be used to build a one-dimensional simulation model. To simulate the entire model system and analyze the coupling relationship between different systems to achieve optimal control of complex systems.
