4.5.4 Compliance for 4.5.1 – 4.5.3 can be achieved through analysis of the lipo battery protection circuit or, if unable to determine through analysis, then through monitoring values during the test of Section 13A.

Performance

Performance of UL2054 Certification

5.1 LiPo batteries are to be tested as described in Sections 9 through 24. Section 12, Forced-Discharge Test, is applicable only to lipo cells intended to be used in multi-cell series applications, such as lipo battery packs. The Battery Enclosure Tests, Sections 18 — 21 (including the 250 N Steady Force, Mold Stress Relief, and Drop Impact Tests) are intended only for batteries that have a plastic outer enclosure.

5.2 With the exclusion of the Projectile Test of Section 22, lipo cells and batteries shall not explode or catch fire as a result of the tests in this standard. For the Shock Test, Section 16, Vibration Test, Section 17, 250 N Steady Force Test, Section 19, Mold Stress Relief Test, Section 20, Drop Impact Test, Section 21, and the Temperature Cycling Test, Section 24 the samples shall also not vent or leak. For these tests, unacceptable leakage is deemed to have occurred when the resulting mass loss exceeds the values shown in Table 5.1, Venting, and Leakage Mass Loss Criteria.

5.3 Deleted August 12, 2008

5.4 Certain end product devices require that the power output of a lipo battery be limited. The Limited Power Source Test described in Section 13 is to be used to determine whether a lipo cell or battery is suitable in such applications where fire hazards may otherwise exist.

Samples of UL2054 Certification

6.1 Unless otherwise indicated, new lipo cells or batteries in the fully charged state are to be used for the tests described in Sections 9 – 24. The test schedule and the number of samples to be used in each analysis are shown in Tables 6.1 and 6.2, for cell testing and battery pack testing, respectively.

6.2 When a lipo battery pack is tested in accordance with Table 6.2, the lipo cells comprising that battery pack shall also be tested in accordance with Table 6.1 if they have not already been.

6.3 All lipo batteries shall be wholly charged in accordance with the battery manufacturer’s specifications prior to testing except for the samples to be subjected to the Abnormal Charging and Abusive Overcharge Tests, which shall be discharged to the manufacturer specified endpoint voltage using the manufacturer specified current prior to testing.

Important Test Considerations of UL2054 Certification

7.1 As some lipo batteries explode in the tests described in Sections 9 — 24, it is crucial that personnel be protected from the flying fragments, explosive force, sudden release of heat, chemical bums, and noise results from such explosions. The test field is to be well ventilated to protect the organization from possible harmful fumes or gases.

7.2 The temperatures on the surface of the lipo battery casings shall be monitored during the tests described in Sections 9, 10, 11, 14, and 15. All personnel involved in the testing of batteries are to be instructed never to approach a lipo battery until the surface temperature returns to ambient temperature.

7.3 The tests described in Section 22, Projectile Test, shall be conducted in a separate room or room equipped with an adequate safety barrier separating the test area from the observer.

Temperature Measurements of UL2054 Certification

8.1 Temperatures are to be contained by thermocouples consisting of wires not larger than 24 AWG (0.21 mm2) and not smaller than 30 AWG (0.05 mm2) and a potentiometer-type instrument.

8.2 The temperature measurements on the lipo batteries are to be made with the measuring junction of the thermocouple held tightly against the outer casing of the battery.

Short-Circuit Test

9.1 Lipo cells shall comply with 9.1 — 9.6.

(Underwriter Laboratories Inc. approved battery cell used in the EUT according to UL1642)

9.2 Each fully charged test lipo cell, in turn, is to be short-circuited by connecting the positive and negative terminals of the battery with a circuit load having a resistance load of 80 ± 20 mohm. The temperature of the lipo battery case is to be recorded during the test. The lipo battery is to discharge until a fire or explosion is obtained, or until it has reached an unloaded state of fewer than 0.2 volts and the case temperature has returned to ±10°C (±18°F) of ambient temperature.

9.3 Tests are to be transferred at 20 ± 5°C (68 ± 9°F), and at 55 ± 2°C (131 ± 4°F). The lipo cells are to reach equilibrium at 20 ± 5°C (68 ± 9°F) or 55 ± 2°C (131 ± 4°F) as applicable, before the terminals are connected.

9.4 A lipo cell is to be tested individually unless the battery manufacturer indicates that it is intended for use in series or parallel. For series or parallel use, additional tests on five sets of lipo batteries are to be conducted using the maximum number of lipo cells to be covered for each configuration as specified by the battery manufacturer.

9.5 A lipo cell is to be tested without the assistance of protective devices unless such protective mechanisms are integral to the lipo cell construction.

9.7 LiPo battery packs shall comply with 9.8 —9.12.

 Exception: LiPo battery packs consisting of a single cell, in which the cell has already been subjected to the tests in 9.1 – 9.6 need not be submitted to the standards in 9.8 – 9.12

9.8 Each fully charged test lipo battery pack, in turn, is to be short-circuited by connecting the positive and negative terminals of the battery with a circuit load having a resistance load of 80 ± 20 m ohm. The temperature of the lipo battery case is to be recorded during the test. The lipo battery is to discharge until a fire or explosion is obtained, or until it is completely released and the cell case temperature has returned to ±10°C (±18°F) of ambient temperature.

9.9 Tests are to be transferred at 20 ± 5°C (68 ± 9°F) and at 55 ± 5°C (131 ± 4°F). The lipo batteries are to reach steadiness at 20 ± 5°C (68 ± 9°F) or 55 ± 5°C (131 ± 4°F), as applicable, before the terminals are joined.

9.10 LPo battery pack constructions are to be subjected to a single fault across any protective device in the load circuit of the battery under test. When protective materials actuate during the trial, the examination shall be repeated with the lithium-ion battery pack connected to the maximum load that does not cause the protective devices to open.

Exception: A positive temperature coefficient device which complies with the tests specified in Standard for Thermistor-Type Devices, UL 1434, the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1A, or other protective devices determined to be reliable, may remain in the circuit without being faulted. See Appendix A for additional component standards.

9.11 One of the above five test sample lipo battery packs, tested at 20 ±5°C (68 ±9°F) shall be evaluated with the following additional conditions in place. The terminals are to be subjected to a short circuit condition with a minimum length of 16 AWG (1.3 mm2) bare copper wire. The test is to be conducted on a tissue paper covered softwood surface, and the sample battery pack and exposed leader is to be covered with a single layer of cheesecloth.

9.12 For all samples tested, the lipo batteries shall not explode or catch fire, and the tests shall not result in chemical leaks caused by cracking, rupturing, or bursting of the cell casing.

For battery pack samples tested in accordance with 9.11, the cheesecloth and tissue paper shall not catch fire.

Abnormal Charging Test of UL2054 Certification

10.1 Primary lipo batteries (for example, lipo cells, single lipo batteries, or lipo battery packs) shall comply with 10.2 –10.5 (Secondary lipo battery pack).

10.2 LiPo batteries discharged to the battery manufacturer’s estimated capacity are to be used for this test. The lipo batteries are to be tested in an ambient temperature of 20 ± 5°C (68 ± 9°F).

10.3 Each wholly discharged test sample battery is to be subjected to a charging current of three times the current lc, designated by the battery manufacturer, by connecting it in opposition to a dc-power supply. The test time is to be calculated using the formula: in which it is the charging time in an hour. C is the capacity of the lipo cell /lipo battery in ampere-hours, and lc is the maximum charging current, in amperes, particularized by the battery manufacturer. The minimum charging time is to be 7 hours.

 Exception: At the battery manufacturer’s preference, test currents more significant than the specified three times rated Ic can be applied to expedite the test timeframe, with the minimum charging times as seven hours.

10.4 When a protective device that has been examined for the purpose, actuates during the test, the test shall be repeated with the battery supply connected to the maximum load that does not cause the protective device to open. Protective equipment that has not been investigated for the purpose shall be short-circuited.

10.5 The lipo batteries shall not explode or catch fire. For lipo battery pack samples, tests shall not result in chemical leaks caused by cracking, rupturing, or bursting of the series casing.

10.6 Secondary lipo cells shall comply with 10.7 – 10.9 (Underwriter Laboratories Inc. approved battery cell used in the EUT according to UL1642)

10.7 The lipo cells are to be tested in an ambient temperature of 20 ± 5°C (68 ± 9°F). Each lithium-ion battery shall be discharged at a constant current of 0.2 C/1 hours, to a manufacturer specified discharge endpoint voltage.

10.8 The lipo cells are to be charged with a constant maximum specified charger output voltage and a current limit of three times the maximum current Ic, particularized by the battery manufacturer. Charging duration is the time required to reach the manufacturer’s specified end-of-charge condition plus seven further hours.

10.9 A lipo cell is to be tested without the assistance of protective devices unless such protective mechanisms are either integral to the cell constructions or have been investigated for the purpose. A piece of re-settable protective equipment that actuates during the test shall be allowed to reset, and the examination shall be resumed, cycling as often as necessary to complete the test. When a protective device operates during the test (whether re-settable or not), the test is repeated with the same charging time, but with the lipo cell connected to the maximum load that does not cause the protective devices to operate. A piece of protective equipment that is not integral to the cell, and that has not been investigated for the purpose is to be short-circuited.

10.10 Secondary lipo battery packs shall comply with 10.11 — 10.13.

10.11 The lipo batteries are to be tested in an ambient temperature of 20±5°C (68±9°F). A thermocouple is to be attached to the lipo cells of each test sample battery. Each lithium-ion battery shall be discharged at a constant current of 0.2C/1 hour, to a manufacturer specified discharge endpoint voltage.

10.12 Each of the test sample batteries are to be subjected to the following overcharge states, in sequential order. a) The lipo battery is to be initially charged using a constant current charging mode with a current limit of three times the highest current Ic, particularized by the battery manufacturer until the maximum specified charger output voltage is reached. At that point, the lipo battery is to be charged with a constant maximum specified charger output voltage and a current limit of three times the maximum current Ic. Charging duration is the time required to reach the manufacturer’s specified end-of-charge condition plus seven additional hours. The temperature on the lipo cell casing shall be monitored. A re-settable protective device such as a PTC that actuates during the test shall be allowed to reset, and the examination shall be resumed, cycling as often as necessary, but no less than ten times, to complete the test. Automatic reset devices are allowed to cycle during the trial. When an overcurrent protective device operates during the trial, the test is repeated with the same charging time, but with the battery connected to the maximum load that does not cause the protective devices to operate. b) The charge condition in accordance with (a) shall be conducted with each single component fault that is likely to occur in the charging circuit and which would result in overcharging of the battery. Exception No. 1: A protective device determined to be reliable may remain in the loop without being faulted. See 2.4 and Appendix A. Exception No. 2: For batteries without protective devices, the overcharge condition(s) in (b) does not apply.

10.13 The lipo batteries shall not explode or catch fire. For lipo battery pack samples, tests shall not result in chemical leaks caused by cracking, rupturing, or bursting of the internal cell casing.

Abusive Overcharge Test of UL2054 

(Underwriter Laboratories Inc. approved lipo battery cell used in the EUT according to UL1642)

The test is to continue until the lipo cell or battery explodes, vents, or a single operation protective device operates, and the temperature of the internal cell casing reaches steady-state requirements or returns to ambient. If a PTC or other re-settable protection device works during the test, it is to be reset a minimum of 10 times during the trial. An automatic reset device is allowed to cycle during the trial.

11.3 During the tests, lipo batteries supplied with protective devices shall be subjected to a single part fault using any individual fault condition, which is likely to occur in the charging circuit and which would result in overcharging of the lipo battery.

Exception: Protective devices determined to be reliable, may remain in the circuit without being faulted. See Appendix A.

11.4 The samples shall not explode or catch fire.

11.5 At least one of the five lipo batteries shall be subjected to the test outlined in 11.2 and 11.3 with a constant current charge five times the C5 rate (for example: at the C rate) with a supply voltage sufficient to maintain that rate throughout the duration of the test

Forced-Discharge Test of UL2054 Certification

12.1 This test is intended for lipo cells that are to be used in multi-cell applications, such as lipo battery packs. The LiPo batteries are to be tested in an ambient temperature of 20 ±5°C (68 ±9°F).

12.2 For multi-cell series configurations without parallel strings, a wholly discharged cell is to be force-discharged by connecting it in series with fully charged LiPo batteries of the same kind. The quantity of entirely charged cells to be connected in series with the discharged cell is to equal the total number of cells in the pack less one.

12.3 For multi-cell series arrangements with parallel strings, a wholly discharged identical line is to be force-discharged by connecting it in series with entirely charged cells of the same kind.

12.4 Each of the five battery packs shall be prepared as described in 12.2 or 12.3, as applicable.

12.5 Once the completely discharged LiPo cells (or string of cells) are connected in series with the specified number of fully charged cells, and the resultant battery pack is to be short-circuited.

12.6 The positive and negative terminals of the sample are to be connected with copper wire with a resistance load of 80 ± 20 m ohms. The battery is to discharge until a fire or explosion is obtained, or until it has reached a completely discharged state and the cell case temperature has returned to ±10°C (±18°F) of ambient temperature.

12.7 During the tests, LiPo batteries supplied with protective devices shall be subjected to a single component fault using any single fault condition, which is likely to occur in the discharge circuit and which would result in excessive discharge of the battery.

 Exception: A positive temperature coefficient device which complies with the applicable tests specified in the Standard for Thermistor-Type Devices, UL 1434 and the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1A, or other protective devices determined to be reliable, may remain in the circuit without being faulted.
