Nowadays, new energy vehicles can be seen all over the world. New energy taxis, buses, cars, etc. shuttle on the road. The core component of electric vehicle power is lithium-ion battery, and people are paying more and more attention to its performance and safety characteristics, and relevant ICE standards are also formulated and released. IEC62660 is a series of IEC standards for lithium batteries (including batteries) for electric road vehicles. Its contents include performance testing, reliability testing, safety requirements, etc.
1. Test introduction
IEC 62660-1 Performance evaluation:
size, weight, electrical performance (capacity, SOC adjustment, power, energy, storage, cycle life, energy conversion efficiency);
IEC 62660-2 reliability and abuse evaluation:
electrical performance capacity, SOC adjustment), mechanical test (vibration, mechanical hit, extrusion), temperature test (high temperature tolerance, temperature cycle), electrical test (external each circuit, Overcharge, forced discharge)
IEC 62660-3 safety requirements:
electrical performance (capacity, SOC adjustment), mechanical test (vibration, mechanical shock, extrusion), temperature test (high temperature tolerance, temperature loop), electrical test (external short circuit, overcharge, forced discharge, internal short circuit).
2. Series Standard Introduction
3. Test object
: Secondary lithium batteries (for electric road vehicles): The electric road vehicle range includes pure electric vehicles (BEV) and hybrid electric vehicles (HEV).
