[0002] In recent years, the development of new energy has attracted attention, especially the rapid development of lithium-ion batteries, which has become the focus of attention in the new energy industry. However, lithium-ion batteries emit more heat when used for a long time. Therefore, for lithium-ion batteries Heat dissipation is particularly important, so it is necessary to carry out research on heat dissipation measurement and control of lithium-ion batteries. Through measurement experiments and margin cleaning analysis, the heat dissipation index can be determined to provide data support for the efficient cooling scheme design of lithium batteries. Simulation technology is an important analysis method for analyzing the thermal conditions of battery cells and lithium-ion battery pack systems during their working process. It is often used for the optimal design and evaluation of battery cells and lithium-ion battery pack systems. The function of the simulation equipment on the Internet is relatively simple, and the heat dissipation analysis of lithium electronic batteries is not in place, and the effect is poor. Therefore, we propose a heat dissipation analysis simulation equipment based on the Internet of Things for lithium battery protection.
