Abstract: Powertrain electrification is one of the promising ways to reduce greenhouse emissions from fossil fuel. For a passenger car, the onboard energy storage for a purely electric drive is limited due to the capacity of batteries. The global energy efficiency and the battery lifespan preservation need more investigations over a long trip (i.e. the trip length exceeds the available vehicle autonomy). Furthermore, the overall trip duration is extended with the battery charging time and obviously, letting the battery to be depleted heavily before stopping for charging can help to reduce this trip duration. However, the battery lifespan is negatively affected by these high depth-of-discharges. On the other hand, stopping often in order to charge the battery and prevent a high depth-of-discharge will potentially increase the overall trip duration. Therefore, a trade-off must be found between preserving the battery lifespan and keeping reasonable the trip duration. In this technical tutorial, a review of some of the well-known vehicle parameter identification methods will be presented prior to the formulation of the convex optimization problem that can produce a feasible charging schedule for an electric vehicle.

Abstract: Currently, hybrid electric vehicles (HEVs) and plug-in HEVs (PHEVs) with advantages of low emission and low fuel consumption, have attracted wide attention of government and corporation. The complex powertrain structure of HEVs/PHEVs exhibits more degrees to achieve the power split thereby improving fuel economy. It is imperative to conduct research into the energy management strategies with the target of optimizing the fuel economy and lowering the emission. The tutorial aims to provide the developed viewpoints of energy management in terms of HEVs/PHEVs, for the sake of introducing the current study progress and the future directions. The overall contexts mainly include: 1) an overview as well as the key difficulties for the energy management; 2) the state-of-the-art energy management strategies; and 3) the future exploratory directions.

Abstract: Electrical drives are increasingly used in automotive industry. Rigorous performance evaluation has to be made during equipment development and before implementation on actual systems. In particular, interactions of the drive with the motion part have to be studied thoroughly. Computer simulation of the entire system is an established means to investigate interactions between subsystems to set the technical requirements. Within the past decade, Hardware-In-the-Loop (HIL) simulations became an advanced means for investigative experimentation, model validation and testing before implementation of drives in actual processes. In addition to pure computer simulation, HIL simulation replaces some simulation models of a system by one or several actual components. The rest of the system and processes are simulated in real-time, which typically requires a parallel computing environment with adequate input-output capability for signals of adequate bandwidth. Most recently, incorporating power hardware (i.e. the drive) into an HIL simulation has been introduced by means of high power and high bandwidth power electronic amplification equipment. Due to the flexibility of HIL simulations to test a wide range of operating conditions and scenarios this method will contribute to improving the availability and reliability of drives (machines, power electronics, and/or control) and a better understanding of system interactions before their insertion on the system. HIL simulation has been intensively used for controller assessment for a long time. The aerospace industry has used this technique since flight control systems is a safety-critical aspect. This methodology yields exhaustive testing of a control system to prevent costly and damageable failures. Moreover, HIL simulations reduce development time and can enable more tests than on the actual system. From 90’s, many groups in automotive industry have employed HIL simulation for testing embedded Electronic Control Units (ECU). Indeed, this methodology avoids intense and complex integration tests on the actual vehicle. Thus, the time development can be reduced and a high quality assurance can be obtained. HIL simulation is becoming a standard for ECU development in the automotive industry. HIL simulation is nowadays more and more used to develop new components and actuators in many fields. Vehicle component evaluation, assessment of drive controls, railway traction systems for trains and subways, power propulsion systems for electric vehicles (EVs) and hybrid electric vehicle (HEVs).

Abstract: Lithium-ion cells are the standard choice for e-mobility and consumer electronics, and costs continue to decrease rapidly. However, a reliable battery management system (BMS) is required to mitigate safety risks such as overheating or overcharging, as well as to track state of charge and other metrics. Battery models play an essential role in the design of battery packs and management systems, but a confusingly wide range of approaches is possible. This tutorial will equip attendees with a clear path through the possibilities. The first part (battery modelling) will cover how a lithium-ion cell works, how to model open circuit voltage, electrochemical models, equivalent circuit models, pack modelling, degradation and temperature effects. The second part of the tutorial (battery management) includes an overview of BMS functions, sensing requirements, diagnostics and prognostics approaches, balancing systems, and hardware in the loop simulators.
