Stage 4 Method of Compliance Issue Paper (IP) SE-2, dated 5/23/2023 identifies the following requirements.

Safety Objectives:

SO 1: Be designed to maintain safe cell temperatures and pressures under all foreseeable operating conditions to prevent fire and explosion.

SO 2: Be designed to prevent the occurrence of self-sustaining, uncontrollable increases in temperature or pressure, and automatically control the charge rate of each cell to protect against adverse operating conditions, such as cell imbalance, back charging, overcharging, and overheating.

SO 3: Not emit explosive or toxic gases, either in normal operation or as a result of its failure that may accumulate in hazardous quantities within the airplane.

SO 4: Meet the requirements of §23.2325(g).

SO 5: Not damage surrounding structure or adjacent systems, equipment, components, or electrical wiring from corrosive or any other fluids or gases that may escape in such a way as to cause a major or more-severe failure condition.

SO 6: Have provisions to prevent any hazardous effect on airplane structure or systems caused by the maximum amount of heat it can generate due to any failure of it or its individual cells.

SO 7: Have a failure sensing and warning system to alert the flight crew if its failure affects safe operation of the airplane.

SO 8: Have a monitoring and warning feature that alerts the flight crew when its charge state falls below acceptable levels if its function is required for safe operation of the airplane.

SO 9: Have a means to disconnect from its charging source in the event of an over-temperature condition, cell failure or battery failure.

Additional IP Compliance Requirements:

The Instructions for Continued Airworthiness (ICA) required by Appendix A to 14 CFR part 23 must include the following;

1. Maintenance requirements to replace each rechargeable lithium battery within an interval that will ensure there is sufficient charge to power equipment.

2. A requirement to only replace rechargeable lithium batteries with batteries from the same manufacturer with the same part number or to obtain a new FAA approval for installing a different battery. Refer to the battery Original Equipment Manufacturer maintenance manual.

3. Procedures to ensure that each rechargeable lithium battery has not:

- Experienced degraded charge retention ability or other damage during storage.

- Been damaged from environmental or physical impacts such as mechanical shock, vibration, heat and possible abuses encountered during storage, transportation prior to their installation or maintenance activities on or around them.

4. Precautions to prevent mishandling of replacement rechargeable lithium batteries prior to their installation which could result in short-circuit or other unintentional damage.

For Lithium Battery installed in a Designated Fire Zone (DFZ) Installation in a DFZ should be avoided but may be acceptable if the battery location does not create an additional hazard. The battery external fire threat when located in a DFZ is a 2000⁰ F flame for 15 minutes per AC 20-135. The heat generated by this flame may cause multiple cells to enter thermal runaway along with damage to the battery containment system resulting in uncontrolled fire or explosion.

Compliance to §23.2440(c)(1) includes the following:

1. Exposing the battery installation to a 20000 F flame for 15 minutes will not result in a hazard to the airplane, and

2. Minimize the risk of fire in the DFZ by venting and directing any potential flammable material from the battery out of the fire zone in the event of a battery thermal runaway.

3. Th e vent system (if applicable) must function in the event of a fire in the DFZ unless it is shown that the failure of the vent does not create a hazard.

Uncontained Engine or APU Rotor Failures: Sections 23.2410 and 23.2510 at Amendment 23-64:

Battery Thermal Runaway Containment Test (RTCA/DO-311A, Section 2.4.5.5) Section 2.4.5.5 describes the test methods for battery thermal runaway containment, which intends to force the entire battery into a thermal runaway state. This may not be feasible for very large high capacity systems (e.g., systems used for propulsion applications). To address the feasibility of very large high capacity battery system testing, this section of the issue paper defines a module or sub-pack as a battery system divided into smaller configurations to help in testing and validating the safety implication of the battery system. The battery and battery system can be designed into several smaller modules or sub-packs. Each module has an assembly of cells electrically connected and enclosed in a single enclosure. Each sub-pack has an assembly of electrically connected modules that is enclosed by a single enclosure. The venting design of the sub-pack, module, and cells need to be considered in the mitigation strategy.

In order to successfully comply with the requirement of the RTCA DO-311A, section 2.4.5.5 test, it is acceptable to use a modularized/sub-pack battery system design.

Coordinate as soon as possible with the FAA on the proposed design methodology.

For Lithium Battery installed in Acrobatic and Utility Category Aircraft Installation in acrobatic and utility category aircraft pose unique environmental conditions related to loading and orientation. These conditions cannot create additional hazards.

Thermal Runaway effects can be affected by the orientation of the battery. Acrobatic maneuvers involving high G loads may also impact battery performance. Both of these potential issues need to be addressed by the applicant and/or battery OEM via the operating and/or installation instructions.

All orientations not tested and validated by the OEM and documented in the installation manual need to be evaluated for any additional hazards to the aircraft and occupants.
