This course is offered in China only. More and more stringent emission and fuel consumption regulations are pushing the automotive industry towards electrified powertrain and electrified vehicles. This is particularly evident in China, where there is an increased demand for electric (EV) and hybrid electric vehicles (HEV). Infrastructure is being built across the country for convenient charging. It must now be determined how to meet the technical targets for EV/HEV regulations under economic constraints and how to best develop the major ePowertrain components (battery and motor).

Electric and hybrid vehicles are becoming more visible on today's roadways and the automotive companies are working hard to make these vehicles as transparent as possible to enhance consumer acceptance. The battery system forms a key part of any of these vehicles and is probably the least understood. With practically no moving parts the battery systems show no visible or audible warning of any latent dangers. This seminar will introduce participants to the risks encountered in handling high voltage battery systems and their component parts.

Driven by the need for lower emissions, better fuel economy and higher efficiency, hybrid vehicles are appearing in many different configurations on today's roadways. While the powertrain components such as the drive motor, motor controller and cooling system are somewhat familiar to the automotive industry, the battery systems are a relatively unfamiliar aspect. This seminar will introduce participants to the concepts of hybrid vehicles, their missions and the role of batteries in fulfilling those requirements.

Abstract A coupled magnetic-thermal model is established to study the reason for the damage of the starter motor, which belongs to the idling start-stop system of a city bus. A finite element model of the real starter motor is built, and the internal magnetic flux density nephogram and magnetic line distribution chart of the motor are attained by simulation. Then a model in module Transient Thermal of ANSYS is established to calculate the stator and rotor loss, the winding loss and the mechanical loss. Three kinds of losses are coupled to the thermal field as heat sources in two different conditions. The thermal field and the components’ temperature distribution in the starting process are obtained, which are finally compared with the already-burned motor of the city bus in reality to predict the damage. The analysis method proposed is verified to be accurate and reliable through comparing the actual structure with the simulation results.

Spray and combustion characteristics of diesel fuel were investigated in order to get a better understanding of the evaporation and combustion behavior under simulated cold-start conditions of a diesel engine. The experiment was conducted in a constant volume combustion chamber and the target ambient conditions were selected as the engine cranking. Mie scattering and shadowgraph techniques were conducted to visualize the liquid and vapor phase of the fuel under non-combustion condition (O2 concentration=0%). In-chamber pressure and direct flame visualization were acquired for spray combustion condition (O2 concentration=21%). The fuel was injected with an injection pressure of 30MPa, which is a typical value during cranking period. The liquid penetration of the fuel was increased at 573K of ambient temperature compared to that at 663K due to the poor evaporation characteristic and the increased fuel viscosity from the lower fuel temperature.

Due to the need to properly quantify vehicle emissions in real world operation, Real Driving Emissions (RDE) test procedures will be used for measuring gaseous emissions on new EURO 6 the RDE 1 & 2: Commission Regulation (EU) 2016/427 of 10 March 2016 amending Regulation (EC) No 692/2008 as regards emissions from light passenger and commercial vehicles. Updated regulations have been enhanced to define RDE tests boundaries and data analysis procedures, in order to provide an accurate way to obtain representative results. The boundary conditions defined for vehicle testing include external atmospheric temperature, which can range from 0ºC to around 30ºC, for moderate conditions and -7oC up to 35oC for extended conditions in RDE tests. As a result of this range of possible test ambient temperature, pollutant emissions and energy consumption can vary considerably.

ISO 26262: Road Vehicle - Functional Safety is now becoming a condition of compliance for doing business in the automotive sector. The Scope states: “ISO 26262 is intended to be applied to safety-related systems that include one or more electrical and/or electronic (E/E) systems and that are installed in series production passenger cars with a maximum gross vehicle mass up to 3,500 kg…" This course provides background for reading and applying the standard and explains its scope, the major differences from the general safety standard IEC 61508, and how the scope changes with the introduction of new systems.
