Special Issue Information

Dear Colleagues,

Climate change and the need for sustainable use of the earth's resources, as well as the on-going worldwide trend towards individual mobility, lead to the necessity to provide vehicles which can be powered with regenerative energies. Today, a wide-spread consensus can be observed that electric and hybrid vehicles will be one of the cornerstones of a successful transformation towards sustainable mobility.

In recent years, several electric and hybrid vehicles were developed and successfully launched in the international car market. However, several issues such as the limited range, the high vehicle weight, the charging time, and safety issues, require further development and advancements. This Special Issue intends to offer a forum for ongoing developments, fundamental improvements and break-trough ideas. The topics of interest include, but are not limited to:

  • Improved electric and hybrid drivetrains;
  • Improved batteries for electric and hybrid vehicles;
  • Improved battery charging strategies and technology;
  • Improved vehicle concepts for electric and hybrid vehicles;
  • Improved suspension systems for electric and hybrid vehicles;
  • Improved car interiors for electric and hybrid vehicles;
  • Improved methods for the product development of electric and hybrid vehicles;
  • Improved coordination of electric and hybrid vehicles;
  • Improved production methods for electric and hybrid vehicles;
  • Improved safety of electric and hybrid vehicles.

The increasingly stringent CO2 emissions standards require innovative solutions in the vehicle development process. One possibility to reduce CO2 emissions is the electrification of powertrains. The resulting increased complexity, as well as the increased competition and time pressure make the use of simulation software and test benches indispensable in the early development phases. This publication therefore presents a methodology for test bench coupling to enable early testing of electrified powertrains. For this purpose, an internal combustion engine test bench and an electric motor test bench are virtually interconnected. By applying and extending the Distributed Co-Simulation Protocol Standard for the presented hybrid electric powertrain use case, real-time-capable communication between the two test benches is achieved. Insights into the test bench setups, and the communication between the test benches and the protocol extension, especially with regard to temperature measurements, enable the extension to be applied to other powertrain or test bench configurations. The shown results from coupled test bench operations emphasize the applicability. The discussed experiences from the test bench coupling experiments complete the insights. Full article

Current batteries of battery electric vehicles (BEVs) require a battery management system (BMS) in order to enable a safe and long-lasting operation. The main functions of the battery management systems are a continuous monitoring of the voltage of each cell, a continuous monitoring of the battery temperature, the control of the charge current and the discharge current as well as the prevention of both a deep discharge and an overcharging. For the realization of these functions, different architectures are possible, ranging from an individual intelligent system at each cell up to a realization of the whole BMS within one central computing unit for the whole vehicle. This paper investigates and structures different architectural possibilities, discusses analysis possibilities and presents approaches for the synthesis of sensible architectures such as BMS. A concept synthesis for the start-up and shut-down of the high-voltage system is presented by comparing three different integrated pre- and discharging circuits and using a Hardware-in-the-Loop (HiL) program as an example. Finally, a topology consisting of three switches and two resistors (3S2R2) turns out to be the best one, due to the number of components, safety and price. Full article
