However, the optimal\u0000 result from deep reinforcement learning is based on multiple sufficient training\u0000 processes, which are time-consuming and hard to be applied in real-time vehicle\u0000 energy management. This study aims to use expert knowledge to warm start the\u0000 deep reinforcement learning for the energy management of a hybrid electric\u0000 vehicle, thus reducing the learning time. In this study, expert domain knowledge\u0000 is directly encoded to a set of rules, which can be represented by a decision\u0000 tree. The agent can quickly start learning effective policies after\u0000 initialization by directly transferring the logical rules from the decision tree\u0000 into neural network weights and biases. The results show that the expert\u0000 knowledge-based warm start agent has a higher initial learning reward in the\u0000 training process than the cold start. With more expert knowledge, the warm start\u0000 shows improved performance in the initial learning stage compared to the warm\u0000 start method with less expert knowledge. The results indicate that the proposed\u0000 warm start method requires 76.7% less time to achieve convergence than the cold\u0000 start. The proposed warm start method is also compared with the conventional\u0000 rule-based method and equivalent consumption minimization strategy. The proposed\u0000 warm start method reduces energy consumption by 8.62% and 3.62% compared with\u0000 the two baseline methods, respectively.

The electric drivetrain\u0000 in xEV (more than one propulsion energy converter) applications substitutes or\u0000 supports the internal combustion engine (ICE) operation with electric machine\u0000 (EM) power. Malfunctions in the electric drivetrain will lead to an increase in\u0000 ICE power demand. Hence, the electric drive system is classified as a\u0000 comprehensive component in the OBD legislation. The regulation defines\u0000 monitoring of the EM performance. The malfunctions that could prevent the EM(s)\u0000 from properly operating emission control strategies, including any ICE control\u0000 activation or electric drivetrain performance degradation, should be monitored\u0000 by the OBD system. This work demonstrates an approach to systematically\u0000 transform generic OBD legislation requirements into granular component\u0000 malfunctions based on a simulation approach in the early development phase for\u0000 an electric drivetrain. In the first step, the generic legislation requirements\u0000 of properly functioning emission control strategies and performance degradation\u0000 are transformed into electric drivetrain system element functional attributes.\u0000 The malfunctions from different sources were collected as a potential\u0000 malfunctions list including malfunction characterization.

In this article, a new energy\u0000 management strategy (EMS) is developed that improves fuel efficiency (FE) and\u0000 suppresses the degradation of the battery. A hybridized two-layer algorithm that\u0000 combines multi-objective nonlinear model predictive control (NMPC) with a\u0000 rule-based (RB) algorithm is proposed as a new EMS that is called RB-NMPC. The\u0000 RB-NMPC is designed to optimize the torque split between the engine and electric\u0000 motors while maintaining the maximum and minimum constraints of each component.\u0000 The proposed EMS is incorporated into control-oriented vehicle models, and their\u0000 performances are analyzed for different driving cycles by comparing with RB,\u0000 dynamic programming (DP), and NMPC. In addition, the RB-NMPC algorithm is\u0000 applied for two different powertrain configurations of HEV, P0P2 and P1P2\u0000 configurations for both an Urban Dynamometer Driving Schedule (UDDS) and a\u0000 Highway Fuel Economy Test (HWFET). For P0P2, the results show that RB-NMPC\u0000 outperforms other methods for UDDS with an FE that is 4.7% higher than that of\u0000 RB and is the closest to that of DP, which is an optimal standard that is\u0000 limited for real-time application due to its complexity among others. The\u0000 capacity loss of the battery using RB-NMPC is 19.1% less than that using DP when\u0000 applied to the UDDS. The FE of P1P2 is higher than that of P0P2, but the similar\u0000 capacity fade is comparable. RB-NMPC shows the lowest capacity loss for both\u0000 P0P2 and P1P2 configurations. Parallel comparisons are performed for the HWFET.\u0000 For the HWFET, the FEs of P0P2 and P1P2 are similar. However, the capacity fades\u0000 by RB-NMPC are 16.3% and 67.0% reduced compared to that by DP for P0P2 and P1P2,\u0000 respectively. Finally, to verify the effectiveness of the RB-NMPC in reducing\u0000 battery aging, the currents from DP and RB-NMPC EMSs are applied to pouch-type\u0000 lithium-ion batteries and tested for multiple UDDSs using a battery test\u0000 station. The results demonstrate that the RB-NMPC can effectively reduce battery\u0000 aging.","PeriodicalId":36261,"journal":{"name":"SAE International Journal of Electrified Vehicles","volume":"94 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85709503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the causes of the onset and subsequent propagation of the\u0000 thermal runaway phenomenon is an area of active research. It is well known that\u0000 the thermal runaway phenomenon is triggered when the heat generation rate by\u0000 chemical reactions within a cell exceeds the heat dissipation rate. Thermal\u0000 runaway is usually initiated in one or a group of cells due to thermal,\u0000 mechanical, and electrical abuse such as elevated temperature, crushing, nail\u0000 penetration, or overcharging. The rate of propagation of thermal runaway to\u0000 other cells in the battery pack depends on the pack design and thermal\u0000 management system. Estimating the thermal runaway propagation rate is crucial\u0000 for engineering safe battery packs and for developing safety testing protocols.\u0000 Since experimentally evaluating different pack designs and thermal management\u0000 strategies is both expensive and time consuming, physics-based models play a\u0000 vital role in the engineering of safe battery packs.

Hybrid drives, though not widely applied in two-wheelers, can reduce\u0000 fuel consumption and CO2 emissions. In this work three hybrid\u0000 topologies, viz., P2 (electric motor placed between engine and transmission), P3\u0000 (electric motor placed between transmission and final drive), and power-split\u0000 concepts (with planetary gear-train) have been modeled in Simulink, and their\u0000 fuel consumption and emissions under the World Motorcycle Test Cycle (WMTC) have\u0000 been evaluated.

A\u0000 map-based fuel consumption model and a Neural Network (NN)-based transient\u0000 emission model were used for the engine. The NN-based transient emission model\u0000 avoids the need to model the air path and fuel path in transient conditions,\u0000 which is time consuming.

A significant portion of the wheel energy input can be\u0000 recovered through efficient regenerative braking in the WMTC.

Validating\u0000 plausible options before building the powertrain prototype has the potential of\u0000 accelerating the vehicle development even more, doing so without shipping\u0000 components around the world. This work concerns the design of a system to\u0000 virtually couple—that is, avoiding physical contact—geographically distant test\u0000 rigs in order to evaluate the components of a powertrain.
