1. Introduction Lithium-ion batteries (LIBs) are highly preferred in the new energy vehicles industry due to their numerous advantages such as high energy density, extended service life, high output power, and excellent environmental adaptability [ 1, 2, 3 ].
Safety testing of lithium batteries is important for understanding and analyzing the failure behavior and mechanism of electric vehicles (EVs). It is also a direct reflection of the safety problems of the batteries. Safety testing of LIBs is crucial for addressing the key factors restricting the rapid development of EVs.
Moreover, we evaluate safety test approaches for an entire range of automotive hardware sets from cell to pack. We also discuss challenges in building this framework and directions for its future development. Battery safety is a key focus in the design of electrified vehicles.
Laboratory crash tests show both vulnerabilities and ways to improve the safety of lithium-ion batteries used in electric and hybrid vehicles. Lithium-ion batteries are lightweight, fully rechargeable, and can pack a lot of energy into a small volume — making them attractive as power sources for hybrid and electric vehicles.
Testing the mechanical abuse of lithium-ion batteries involves various methods to ensure their safety under external mechanical force. Common tests include crush/crash tests such as extrusion, nail penetration, and vibration tests. (2.1. Crush/Crash Test)
Furthermore, one or more safety features (such as safety vents, shutdown separators and current interruption devices) can be included in cells to protect against off-normal conditions 7, 8. These technologies work together and can notably decrease the severity of failures of lithium-ion batteries 8.
