PHYSICAL REQUIREMENTS 5.1 Mechanical Retention A retention system to attach components and the battery system to the vehicle shoul

31、d provide for retention in the three mutually perpendicular axes. The restraint need not contact the entire surface in the axis being restrained, i.e., small areas of contact are satisfactory as long as no damage is done to the components. 5.1.1 Physical/Mechanical Performance Requirements a. Any re

32、straining system used shall not inhibit the normal electrical operation or ventilation of the module(s) through either physical or electrical obstructions. If an air draft system is used for thermal management or hydrogen gas emissions, the retention system should not hinder airflow around the modul

33、e(s) needed for proper thermal management or venting of the entire battery system. b. The restraints should retain the orientation and position of the modules during vehicle operations. Crash performance as described in SAE J1766, is recommended to ensure that the retention system remains intact. It

34、 should also not directly damage modules, which could result in electrolyte leakage.c. Any retention system should maintain electrical isolation during a crash as referenced in SAE J1766. The retention system should prevent current leakage and should be protected against electrolyte corrosion. The r

35、etention system should not allow damage to sensor wiring, vent tubes, thermal management components, or primary traction wiring leads under all but extreme conditions. SAE J2289 Revised JUL2008 - 5 -5.1.2 Retention of Components in a Battery Pack System It is recognized that there are a multitude of

36、 methods by which to restrain both single modules and multiple modules connected together in a system. Although electrical cables and connections may seem to provide some form of retention and restraint of modules in relation with one another, this is not considered to be a part of an acceptable ret

37、ention system that provides restraint in normal and some safety critical situations. Fasteners, used to mount components to the structure should consider the strength over time and corrosion due to the emission (leakage or spillage) of electrolyte, or other contaminants that may enter the battery sy

38、stem. Use of high stress clamping retention should be evaluated in the light of not exceeding the force required to damage thermal welds of plastic structures or stress the electrical isolation of metal cans or to cause deformation of the module/cell surface. 5.1.3 Retention of Battery Pack to Vehic

39、le Sufficient structural strength is required to withstand severe contact loads from FMVSS Crash conditions and rollover without ejecting modules or while providing clearance to the vehicle body. Retention should be sufficient to prevent damage to the batteries by repetitive motion contact. In addit

40、ion it is necessary to provide retention to protect the battery and the vehicle from damage or affect overall pack reliability. 5.2 Installation/Removal for Service Battery pack design should consider installation and removal by service personnel. One consideration is structural support of the batte

41、ry tray during installation and removal after it has been disconnected from the vehicle. During this time, some additional structure (pallet or other) may be needed to support the battery pack to preclude damage and enable movement by fork lift trucks or cranes to move a battery pack from the servic

42、e bay to a transport truck in instances of swapping or offsite servicing of a battery pack. Clearances on the vehicle that are adequate to enable easy installation or removal of a battery pack should be verified during vehicle design to simplify service operations. SAE J1555 and SAE J2184 may need t

43、o be evaluated to prevent interferences with the battery systems. The vehicle manufacturer should offer detailed service information and training to service personnel. It should include safety procedures due to high voltage potentials in battery systems. 5.3 Clearance 5.3.1 Ground Clearance Ensuring

44、 adequate ground clearance may be required to protect the structural integrity and durability of some battery systems mounted under the vehicles structure. This is to verify that departure angles for a vehicles beginning or ending grade climbs or passing over bumps or other obstacles is not compromi

45、sed. The amount of ground clearance is left to the discretion of the vehicle manufacturer based on vehicle mission and image.5.3.2 Body Clearance Body clearance spacing may be required to provide adequate protection of the battery system components movement to preclude contact of the battery pack or

46、 components to the vehicle. These limits are specified as part of the manufacturers design for manufacture/assembly/service guidelines to assist in developing a robust design. Battery packs should be located to reduce probability of damage. Locating battery packs in susceptible locations should cons

47、ider use of additional crash structure to protect the battery. SAE J2289 Revised JUL2008 - 6 -5.3.3 NVH Compatibility (noise vibration harshness) Battery packs should have sufficient retention to provide structural rigidity and separation from the body. Retention should also be sufficient to prevent

48、 vibrations/low frequency noises that may reduce structural reliability or be objectionable to passengers. Some designs may also include isolation mounts to reduce NVH. 5.4 Durability Requirements 5.4.1 Mechanical Shock Battery systems and components should withstand automotive shock effects. This i

49、ncludes shock induced by shipping and handling, component installation, in-use operation, and crash. Battery modules may have additional shock limitations as described by the battery manufacturer. Section 4.8 of SAE J1211 may be an acceptable standard. Also reference SAE J1555. Battery packs may be exposed to the underside of the vehicle, which could result in ground contact or other impacts such as road debris. 5.4.2 Vibration The bat
