Safety testing of lithium ion batteries for navy devices

Abstract

Lithium ion battery technology is being introduced into power supplies used by our Armed Forces for a variety of applications. In many cases, the same cells and design parameters that support commercial battery packs are being used in military battery packs. This approach is expected to result in a major decrease in the total life cycle cost of the equipment these batteries support.

Effects of solvents and salt on the thermal stability of lithiated graphite used in lithium ion battery

“…When these materials were heated up, they reach the onset temperature and begin to self-heating, even can progress into fire and explosion [2][3][4]. And therefore, the safety of lithium ion batteries has been considered by researchers and manufactures more and more, especially in the recent years [5][6][7][8][9][10][11][12].…”

Experimental Testing and Evaluation of Lithium-Ion Battery Cells for a Special-Purpose Electric Vacuum Sweeper Vehicle

“…Due to the nature of the tests, Tables 5 and 6 show cell discharging time and discharged Tables 7 and 8 contain data on the charging time and charged energy. Temperature measurement results are presented and evaluated because safety aspects [32] and preservation of state-of-health of a battery [33] highly depend on its heating characteristics. Energy Test results in Table 5 indicate that the highest discharging times and discharged energy are achieved for the battery cells with highest capacity (see Table 2).…”

AC Impedance-based Online State-of-charge Estimation for Li-ion Batteries

“…The power that drives electric cars and consumer electronics products mostly comes from secondary (rechargeable) batteries, most of which are Li-ion devices. (1)(2)(3) However, the accurate estimation of the state of charge (SOC) of batteries is crucial to the battery management system (BMS). (4) Currently, methods used for measuring battery SOC include Coulomb counting, open-circuit voltage, ampere-hour, internal resistance, and Kalman filtering.…”
