This SAE Standard defines a minimum set of acceptable safety criteria for a lithium-based rechargeable battery system to be considered for use in a vehicle propulsion application as an energy storage system connected to a high voltage power train. While the objective is a safe battery system when installed into a vehicle application, this Standard is primarily focused, wherever possible, on conditions which can be evaluated utilizing the battery system alone. As this is a minimum set of criteria, it is recognized that battery system and vehicle manufacturers may have additional requirements for cells, modules, packs and systems in order to assure a safe battery system for a given application. A battery system is a completely functional energy storage system consisting of the pack(s) and necessary ancillary subsystems for physical support and enclosure, thermal management, and electronic control.

This SAE Energy Storage System (ESS) Identification provides recommendations to identify energy storage systems with a maximum voltage exceeding 6V but not more than 60V. The ESS identification should be applied, to improve the safety and efficiency of dismantling, sorting and recycling operations. The identification system is intended to support the proper and efficient recycling of rechargeable battery systems used in transportation applications (including SLI batteries). Other battery systems such as non-rechargeable batteries, batteries contained in electronics, and telecom/utility batteries are not considered in the development of this specification. This does not preclude these systems from adapting the format proposed if they so choose. This document provides guidance on legacy energy storage systems as well as defining the future optimal system to eliminate cross-contamination of recycling streams.

This SAE Technical Report Jxxxx provides a draft of a proposed new standard. The proposed Standard establishes requirements to which a vehicle manufacturer can certify conformance by conducting analyses, inspections, and tests to ensure that a specific model of a utility-interactive inverter system, which is integrated into the plug-in electric vehicle (PEV), can be safely connected in parallel with an electric power system (EPS) by way of the electric vehicle supply equipment (EVSE). The requirements herein are limited to those which are necessary to secure approval for the PEV to interconnect and discharge by the authority having jurisdiction for interconnection for such PEV inverters. This standard does not require that a PEV shall provide an onboard inverter system.

For years, the most sophisticated UASs have employed “autonomous” algorithms that allow them to operate for hours without human intervention or control. This autonomy can be perceived as true intelligence but also as dangerous—raising concerns about accidents and moral and legal accountability.

The emergence of tougher environmental legislations and ever increasing demand for increased ride comfort, fuel efficiency, and low emissions have triggered exploration and advances towards more efficient vehicle gearbox technologies. The growing complexity and spatial distribution of such a mechatronic gearbox demands precise timing and coordination of the embedded electronics, integrated sensors and actuators as well as excellent overall reliability. The increased gearbox distributed systems have seen an increased dependence on sensors for feedback control, predominantly relying on hardware redundancy for faults diagnosis. However, the conventional hardware redundancy has disadvantages due to increased costs, weight, volume, power requirements and failure rates. This paper presents a virtual position sensor-based Fault Detection, Isolation and Accommodation (FDIA), which generates an analytical redundancy for comparison against the actual sensor output. The proposed FDIA scheme has been validated experimentally using an electro-hydraulic test rig and the gearshift simulation model, including the non-linear hydraulic actuator dynamics.

Electro-hydraulic actuated systems are widely used in industrial applications due to high torque density, higher speeds and wide bandwidth operation. However, the complexities and the parametric uncertainties of the hydraulic actuated systems pose challenges in establishing analytical mathematical models. Unlike electro-mechanical and pneumatic systems, the nonlinear dynamics due to dead band, hysteresis, nonlinear pressure flow relations, leakages and friction affects the pressure sensitivity and flow gain by altering the system's transient response, which can introduce asymmetric oscillatory behavior and a lag in the system response. The parametric uncertainties make it imperative to have condition monitoring with in-built diagnostics capability. Timely faults detection and isolation can help mitigate catastrophic failures. This paper presents a signal-based fault diagnostic scheme for a gearbox hydraulic actuator leakage detection using the wavelet transform. The novelty of the work is the development of a high fidelity leakage fault detection as low as 0.128 lit/min.
