40、1798.5.5 MassThe maximum mass of the modular unit is found in Table 2 and excludes peripheral systems interfacecomponents, i.e., thermistors, cables, terminal protectors, etc. Ergonomic considerations must be made by thepack manufacturers to ensure due care is used when handling individual modules d
41、uring installation andservicing of packs.6. Systems InterfacesSystems interfaces shall include all peripheral device(s), component(s) or sub-system(s) which interact with the battery module unit(s).6.1 Mechanical Interfaces6.1.1 RETENTION OF MODULE IN BATTERY PACK SYSTEMIt is recognized that there a
42、re a multitude of methods bywhich to restrain both single modules and multiple modules connected together in a system. Althoughelectrical cables and connections may seem to provide some form of retention and restraint of modules inrelation with one another, this is not considered to be a part of an
43、acceptable retention system that providesrestraint in normal and some safety critical situations. Any method used shall consider the following areasand features of the module(s). Use SAE J1766 for retention performance standards.6.1.2 RETENTION LOCATION AND FEATURESThe retention system used shall pr
44、ovide for retention in the threemutually 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 modules and the system canmeet SAE J1766 performance standards.Any retention s
45、ystem should maintain electrical isolation during a crash as referenced in J1766. Theretention system should prevent current leakage and should be protected against electrolyte corrosion. If anair draft system is used for thermal management or hydrogen gas emissions, the retention system should noth
46、inder air flow around the module(s) needed for proper thermal management or venting of the entire batterysystem. The retention system should not interfere with the vent system or high-voltage wiring.6.1.3 TOP/INTERMEDIATE RETENTIONIf applicable, all remaining area on the top surface may be contacted
47、 forrestraint and should be available to the restraint system. If there is a heat seal area of the intermediate coverto top cover, it should not be used to provide edges by which to clamp or connect a restraining system.However, the top surface of the module may be used as a contact surface for the
48、restraint system and shouldprovide as much surface area as possible for maximum usage in retention.6.1.4 BOTTOM RETENTIONThe bottom surface of the module shall provide a level plane for placement in theretention and restraining system. Other retention features are optional.COPYRIGHT Society of Autom

The clamping area and force applied shall not damagethe battery module, particularly in consideration of material creep.6.1.6 INSTALLATION/REMOVALThe retention system should be designed for easy removal and installation ofbattery modules for service.6.1.7 P
