25、RAFT BATTERIES Part 2: Design and construction requirements 1 Scope This part of IEC 60952 series defines the physical design, construction and material requirements for nickel-cadmium and lead-acid aircraft batteries containing vented or valve-regulated cells or monoblocs. The batteries are used fo

26、r both general purposes and specific aerospace applications. The specific topics addressed in this part serve to establish acceptable quality standards required to qualify a battery as airworthy as defined in Clause 3 of IEC 60952-1:2013. A preferred range of aircraft batteries is specified in Annex

27、 A, but this part of IEC 60952 series may be used for other battery sizes, arrangements and ratings. For particular applications, other design requirements may be stipulated. These will be in addition to the requirements of this part and will be covered by specific documents. It is recognised that a

28、dditional data may be required by other organisations (national standards bodies, AECMA, SAE, etc.). The present standard can be used as a framework to devise tests for generation of the required data. 2 Normative references The following documents, in whole or in part, are normatively referenced in

29、 this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60952-1:2013, Aircraft batteries Part 1: General test requirements and perform

30、ance levels 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60952-1:2013 apply. 4 General construction requirements 4.1 General Batteries complying with this standard shall be capable of meeting the requirements of IEC 60952-1 upon commissioning in a

31、ccordance with manufacturer instructions or as specified in the product specification. Batteries designed for utilisation in the aerospace environment shall be sufficiently robust and shall withstand the rigors of normal application, handling, manoeuvres and the full range of operating conditions pe

32、rmitted for the aircraft concerned. Proper integration of nickel-cadmium, and lead-acid batteries into aviation-related equipment requires cooperation between the battery supplier, aircraft designer, and the avionic equipment designer. Only through this cooperative exchange of the aircraft performan

33、ce requirements and the batterys capabilities and limitations can an effective pairing of aircraft, avionics equipment and battery be realised. BS EN 60952-2:201360952-2 IEC:2013 7 Overall, the stated requirements and guidelines contained in this document are generic in nature, and serve only as a b

34、aseline for the design and test for specific battery and equipment pairings. Below are general requirements pertinent to the safety, quality control, configuration control, qualification, storage, shipping, and disposal of nickel-cadmium, nickel metal-hydride, and lead-acid aircraft batteries. 4.2 S

35、afety Safety is the prime consideration in the use of nickel-cadmium, and lead acid batteries on aircrafts. The training of installers, end users and personnel involved in the assembly, handling, installation, maintenance and disposal of nickel-cadmium, nickel metal hydride, and lead-acid batteries

36、with respect to their special characteristics is a necessary safety element. Extreme care shall be taken in the handling, shipping, and storage of nickel-cadmium, nickel metal-hydride, and lead-acid aircraft batteries. Safety concerns include the possibility of fire, explosion, and corrosive nature

37、of the electrolyte and the venting of toxic or flammable gases. The battery shall be constructed so as to avoid the occurrence of short-circuiting of the battery and its components. Terminals of batteries should be covered with non-conductive protection to avoid possibility of shorting during handli

38、ng, shipping, and storage. The battery shall be constructed such that there will be no ignition source inside the battery sufficient to cause ignition of hydrogen/oxygen mixtures in the event of failure of the venting system. All auxiliary equipment such as thermal sensors, thermostats, heaters and

39、switching devices shall be so designed that they cannot be the source of an explosion. The current-carrying components of the battery shall be dimensioned and constructed so as to provide no ignition source under any external short circuit conditions. The battery shall be so constructed that any deb

40、ris due to any internal explosion failure shall be contained within the casing. The battery should be constructed of materials that, in the absence of externally supplied energy, will not support combustion. 4.3 Safety philosophy Aircraft designers must ensure that operational parameters and the env

41、ironment in which the battery is to be used are not more severe than that to which it has been designed and tested. Operation at discharge rates and temperatures exceeding design limits, improper maintenance, and improper storage may result in dangerous battery failure. Additionally, the improper ap

42、plication of batteries may compromise the safety of the aircraft by it not being capable of delivering adequate power during an emergency to support aircraft essential loads for the design duration. Nickel-cadmium, nickel metal-hydride, and lead-acid batteries and the aircraft equipment for which th

43、ey are the power source must be designed such that no single failure in either can cause a safety hazard to the passengers or crew of the aircraft. BS EN 60952-2:2013 8 60952-2 IEC:2013 4.4 Factors influencing safety The battery application and design should be such to avoid the occurrence of short-

44、circuiting of the battery and its components. The battery shall be constructed to minimise ignition sources inside the battery. The battery should be constructed of self-extinguishing materials. Installers and users of nickel-cadmium, nickel metal-hydride, and lead-acid batteries must be informed th

45、at cells and batteries other than those authorized/approved for a particular application shall not be substituted even though they may be of the same physical dimensions, capacity, and voltage. Safe use of nickel-cadmium, nickel metal-hydride, and lead-acid batteries involves more than battery selec

46、tion and testing. Other design and operation factors can have a similar impact on safe use. For example: a) Multiple batteries In general, the use of a single battery is preferred over the use of a number of batteries in series and/or parallel. However, in many aircraft applications due to either ha

47、ndling requirements (weight) or space restriction, separation into more than one battery case may be necessary. b) Mixing of cells or batteries Mixing of cells or batteries from different manufacturers is not an acceptable practice. Cells or batteries of different capacities in series connection wil

48、l result in the lower capacity battery(ies) being driven into deep discharge (forced discharge). Cells or batteries may have different capacities on account of their differences in design, manufacturing process, storage, use, age or history. Therefore, mixing cells or batteries with different part n

49、umbers, made by different manufacturers or from different sources, shall not be allowed. Refer to the OEM maintenance manuals for proper replacement of each manufacturers cells within a battery. c) Battery polarity Installing one or more batteries incorrectly, with the battery output terminals reversed, will result in the reversed battery being charged by other batteries in the circuit during discharge and discharged by the charging system during charge. d) Exposed terminals
