Xiaomi’s CEO, Lei Jun, has shared a video showcasing extreme testing procedures for Xiaomi’s automotive battery, emphasizing that its safety evaluation encompasses an extensive array of up to 1,230 tests, adhering to stringent industry benchmarks. In the footage, a lithium iron phosphate battery, designed to endure the equivalent of 400,000 kilometers of usage, underwent a nail penetration test under challenging conditions: high temperature, full charge, and without water cooling. The outcomes were remarkable; the battery exhibited no leakage, ignition, explosion, or casing rupture, with voltage, temperature, insulation, and other vital indicators all registering within normal ranges. Additionally, two dual-cell nail penetration tests were performed, both of which successfully avoided thermal runaway, fire, or explosion; notably, the first test also activated a thermal runaway alarm signal as a precautionary measure.
