Scope: This document specifies the experimental conditions, technical requirements, and testing methods for 12-V on-board low-voltage lithium-ion power systems. This document is applicable to 12-V low-voltage power systems that can be installed in fuel-powered vehicles, energy-saving vehicles, and plug-in hybrid vehicles, as well as to 12-V main and backup power systems in pure electric vehicles and fuel cell vehicles. Main technical content: The main technical content includes the following: 1) Definitions, symbols, general test conditions, and general test cycles; 2) Electrical performance (maximum pulse discharge current, cycle life, capacity loss during storage, no-load capacity loss, operating voltage range, operating temperature range, storage temperature); 3) Safety performance (vibration, mechanical impact, simulated collision, extrusion, temperature cycling, water immersion, external fire, heat diffusion, temperature shock, salt spray, high altitude, over-temperature protection, over-current protection, over-charge protection, over-discharge protection, short-circuit); 4) Electromagnetic compatibility performance (radiated emission, power line conducted emission, control/signal line conducted emission, high-current injection immunity, transient conducted interference along control/signal lines, electrostatic discharge, portable transmitter immunity); 5) Mechanical, electrical, and communication interface performance requirements.
