Summary Li‐ion cells are used for energy storage and conversion in electric vehicles and a variety of consumer devices such as hoverboards. Performance and safety of such devices are severely affected by overheating of Li‐ion cells in aggressive operating conditions. Multiple recent fires and accidents in hoverboards are known to have originated in the battery pack of the hoverboard. While thermal analysis and measurements have been carried out extensively on large battery packs for electric vehicles, there is relatively lesser research on smaller devices such as hoverboards, where the extremely limited thermal management design space and the critical importance of user safety result in severe thermal management challenges. This paper presents experimental measurements and numerical analysis of a novel approach for thermal management of the battery pack of a hoverboard. Measurements indicate that temperature rise in cells in the pack can be as large as 30°C at 4C discharge rate, which, although unlikely to be a standard discharge rate, may result from a malfunction or accident. A novel thermal management approach is investigated, wherein careful utilization of air flow generated by hoverboard motion is shown to result in significant temperature reduction. Measurements also indicate the key role of the metal housing around the battery pack in thermal management. Measurements are found to be in good agreement with finite element simulations, which indicate that the battery pack can be cooled as effectively in presence of a perforated metal casing as without the casing at all. Experimental data and simulation model presented here offer critical insights into the design of hoverboard thermal management and may result in safer, high performance hoverboard battery packs.

SUMMARYBased on a 1D electrochemical model, a series of galvanostatic charge processes of lithium ion batteries with different initial electrolyte salt concentrations are simulated and investigated. In light of the simulation results, it is found that many electrochemical characters, including charge curve, end-of-charge salt concentration, anode potential, and reaction depth distribution, can all be affected by initial electrolyte salt concentration. Meanwhile, the lithium plating phenomenon commonly occurring during charge is studied with batteries of different salt concentrations during overcharge. A corresponding solution, changing the thickness ratio of anode to cathode, is proposed, which can also be used to extend the charging capacity. Overall, this study gives better understanding of the relevance between electrochemical behaviors of charging battery and initial electrolyte salt concentration, thus emphasizes the important role of electrolyte salt concentration in the performance and health of lithium ion battery.

“…5 in dealing with the overheating issues that accompany Li-ion batteries. Generally, BTM systems can be divided into 4 branches based on their cooling mediums, which include air cooling, [6][7][8] liquid cooling, [9][10][11] heat pipe cooling, [12][13][14] and phase change material (PCM) cooling. [15][16][17][18] As a branch of the passive BTM system, the PCM-based cooling system uses its latent and sensible heat to absorb the excessive heat generated from batteries, which make it not only applicable to the near earth surface applications but also suitable for the in-space applications where the air cooling is inaccessible.…”

Summary Battery thermal management (BTM) system is an indispensable component for large‐sized lithium‐ion battery packs used in aerospace and automotive applications. Besides providing a proper temperature range for batteries to operate, thus improving their efficiency, lifespan, and safety, the BTM system also needs to be well designed with considering the cost, weight, and practicability. In this paper, an internal passive BTM system is proposed for the cylindrical Li‐ion batteries. The design embeds a phase change material (PCM) filled mandrel inside the battery to achieve the cooling effect. A thermal test cell is first fabricated and tested in a wind tunnel under different cooling scenarios, and it is also used to verify a numerical thermal model. The proposed BTM system is further examined through the model and found to be able to create a preferable environment for batteries to operate. Specifically, the core BTM system consumes less PCM and achieves lower temperature rises and more uniform temperature distributions than an external BTM system. The proposed design can also exert its full latent heat to manage the heat generated from the battery without having a thermally conductive matrix, which is usually composite with PCM in external BTM systems. In addition, experiments show that the battery equipped with the proposed BTM system is ready for intensive cycling tests.
