IEC 62660

The international standard series for lithium-ion cells in electric vehicles: part 1 performance testing, part 2 reliability and abuse testing, part 3 safety requirements. It fixes test conditions so results from different labs can be compared.

Battery pack

The complete battery as installed: modules or cells, the BMS, contactors and fuses, busbars, cooling, sensors and an enclosure. Its energy is the sum of its cells’ energies; its mass and volume are a good deal more.

SAE J2464 and J2929

SAE’s abuse-test procedure for vehicle battery systems, J2464, and the safety performance criteria for lithium-ion packs, J2929. They are the North American industry practice behind the regulatory tests, and define the familiar mechanical, thermal and electrical abuse sequences.

UL 1642

The North American safety standard for lithium cells, tested by Underwriters Laboratories through a series of electrical, mechanical and environmental abuse tests. UL 2054 covers the batteries built from them.
