This Recommended Practice proposes test practices to evaluate the Water Leak Tightness of Propulsion Battery Packs that emulates the equivalent results of IEC 60529 to an IPX7 level applying the Selected Equivalent Channel (EC) per SAE J3277 and provide guidelines for proper tooling design, validation, and leak test procedure. This practice is in consideration of the design limitation of some battery packs while utilizing applicable common air or tracer gas leak tightness technologies.
This document describes the megawatt-level DC charging system requirements for couplers/inlets, cables, cooling, communication and interoperability. The intended application is for commercial vehicles with larger battery packs requiring higher charging rates for moderate dwell time. A simplified analog safety signaling approach is used for connection-detection to guarantee de-energized state for unmated couplers with superimposed high speed data for EVSE-EV charging control and other value added services.
SAE J#### establishes the protocol and process limits for hydrogen fueling of light duty vehicles when the fuel delivery temperature is not pre-cooled, so called “ambient fueling” designated by Table 1 of SAE J2601-2014. These process limits (including the fuel delivery temperature, the maximum fuel flow rate, the rate of pressure increase and the ending pressure) are affected by factors such as ambient temperature, fuel delivery temperature and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J#### establishes standard fueling protocols based on a series of design cases representing fueling system engineering categories. These categories are intended to provide performance targets which allow decreasing fueling times relative to the most simple design case. Similar to the table and formula based approaches of SAE J2601-2014, this approach establishes a minimum performance criteria leaving open options for innovation to decrease fueling times.
Develop and document an aerodynamic constant speed procedure for heavy vehicles that can accurately calculate the aerodynamic performance through the typical expected yaw angles during operation at highway speeds.
This SAE RP provides a set of test methods and practices for the characterization of the properties of lithium battery anode active materials. Lithium battery anode active materials can be grouped in one of the following categories: lithium intercalation materials (including graphite, Li4Ti5O12); lithium alloying materials (including Sn, Si compounds/composites); lithium deposition materials (lithium metal). For the purposes of this document, material properties will be examined for particulate anode active materials (graphite, Li4TiO5, Sn compounds, Si compounds) and for metallic films (lithium metal). It is not within the scope of this document to establish criteria for the test results, as this is usually established between the vendor and customer It is not within the scope of this document to examine the electrochemical properties of anode materials since these are influenced by electrode design.
The scope of this document is to provide a guidance of the common contamination types and their concentrations in order to size FTIS components and characterize its performance on generic commercial aircraft.
The purpose of this AIR is to provide a comprehensive description document that displays various examples of low pressure seals and wipers utilized within mechanical and electromechanical actuators. The document is intended as an overview for those specifying or designing actuators in order to compare existing solutions as reference for implementation.
This document defines the technical guidelines for the safe integration, operation and maintenance, and for certification of Liquid Hydrogen Storage Systems (LHSS) in aircraft. This document also defines guidelines for safe refuelling operation of hydrogen for aircraft. This document does not address airport infrastructure, nor how the refuelling means is specified, except the provisions required for the safety of the aircraft refuelling operation.
