On June 25, 2021, UL official website released the latest amendment proposal to the UL2054 standard. The solicitation of opinions lasts until July 19, 2021. The followings are the 6 amendment items in this proposal:
1. Inclusion of the general requirements for the structure of wires and terminals: the insulation of wires should meet the requirements of UL 758;
2. Miscellaneous amendments to the standard: mainly misspelling correction, updates of cited standards;
3. An addition of test requirements for adhesiveness: wiping test with water and organic solvents;
4. Increase of the management methods of components and circuits with the same protection function in the electrical performance test: If two identical components or circuits work together to protect the battery, when considering a single fault, two components or circuits need to be faulted at the same time.
5. Marking the limited power supply test as optional: whether the limited power supply test in Chapter 13 of the standard is carried out will be determined according to the manufacturer’s requirements. The modification of the 9.11 clause – the external short circuit test: the original standard is to use 16AWG (1.3mm2) bare copper Wire; modification suggestion: the external resistance of short circuit should be 80±20mΩ bare copper wire.
