“…In reality, the efficiency fluctuates depending on the gear engaged, the speed and the torque. The clutch is neglected because it has a few impacts on the consumption [ [5]. The transmission torque T tr and rotation speed Ω ice are obtained by the following equations:…”

“…Some concepts today are also based on parallel configuration caused by a quick design and simplified integration into the vehicle [3]. For the retrofitting hybrid system, there exist many places to integrate the electric drive inside the vehicle [5]. The complexity of integration depends directly on the segment of the vehicle and the changes in the transmission.…”

The transformations of conventional Internal Combustion Engine (ICE)-powered vehicles into electrified vehicles are of growing interest. The retrofit hybridization of a Peugeot 308 SW passenger car is studied. For this purpose, a complete hybridization system is added to the rear axle of the vehicle. As a result, the control of the initial ICE-powered vehicle has to be updated. The aim of this paper is to deduce the potential fuel saving thanks to this hybridization. The simulation results show an energy saving of at least 9% and potential consumption reduction on a Worldwide harmonized Light-duty Vehicles Test Cycle (WLTC).

“…The most common concept is the micro-hybrid, also known as start-stop, which automatically shuts off the engine in a situation of many stops (urban traffic), focusing on fuel economy [4]. Two other concepts that do not require electrical supply through an external source are the mild hybrid, with small battery packs and voltage that does not exceed 60V, and the full hybrid, with larger battery packs, electrical autonomy and voltages at the level of 250 ~ 300V [5]. These last two concepts charge their batteries only through braking energy recovery, among other recovery systems that work whenever the vehicle is in motion.…”

“…Although its benefit in terms of economy and emission reduction is considerable, the electric range, even for full hybrids, is small [6]. So looking for solutions that add the reduction of carbon emissions provided by an electric vehicle and greater autonomy, which allows short trips, the plug-in hybrid or even a battery electric vehicle (BEV) are the options available [5] [7]. But in addition to reducing fuel consumption and emissions, the transition to vehicles with a higher level of electrification also leads to smarter mobility, closely associated with artificial intelligence technologies, where traffic safety also becomes one of the most important factors [8].…”

Electrification of the vehicular fleet is a worldwide tendency, considering both hybrid and fully electric solutions. However, many regional barriers hinder the dissemination of these technologies and the feasibility of their application, such as the production of electricity by non-renewable sources and the component costs. In this sense, hybrid platforms equipped with high efficiency internal combustion engines stand out as promising alternatives, even more when biofuels such as ethanol are used. As the hybridization concept is quite broad, different electric motor positioning and coupling architectures can enable operation exclusively by electric mode during parking conditions, cruising speeds, urban routes, among others. The aim of this paper is to evaluate different P0 and P2 hybridization architectures for a passenger car through computer simulation in GT-ISE software, considering experimental data of fuel consumption and engine-out emissions from an ethanol fueled Ford Ecoboost 1.0 l engine. The results show benefits of both architectures when compared to the baseline vehicle under urban driving cycles, pointing to advantages of lighter hybridization strategies which could be adapted to vehicles in production and offered as commercial packages by automakers.

This experimental study investigates the thermal behavior of a 48V lithium-ion battery (LIB) pack comprising three identical modules, each containing 12 prismatic LIB cells, during five charge-discharge cycles. A homogeneous liquid cooling system is applied at the bottom of the modules to control the pack temperature when it reaches 40°C (active cooling phase). The initial two cycles represent passive cooling, where the cooling liquid remains stationary. Temperature distribution is measured and analyzed using 27 thermocouples, providing insights into temperature changes in the cells, modules, pack, and cooling system inlet/outlet. Results show that in passive cooling cycles, minimum temperature occurs at pack surfaces due to better convective heat transfer, while maximum temperature is observed in the central LIB cells. The active cooling phase alters the temperature distribution within the pack. One module is found to be more sensitive to high currents, generating more heat and releasing it faster. Additionally, the positive tab temperature is higher than the negative tab temperature within a single cell. The liquid cooling system decreases the temperature rise from 5.8°C to 3.5°C in the discharge cycles with a constant current of -237A. This study emphasizes the significance of evaluating the thermal behavior of individual modules and highlights the complexity of the LIB pack system, as well as the impact of an indirect liquid cooling system on enhancing its thermal performance.
