“…In this mode, it is observed that the PHEV battery, subjected to high current discharges, experiences the most significant temperature rise, indicating severe thermal stress. However, to accurately assess the battery's temperature increase [16], factors such as charging time, discharging time, and rest intervals need to be considered for each system under this driving condition.…”

The concern for the environment and energy has led to a significant increase in research on electric vehicles (EVs) and hybrid electric vehicles (HEVs). The main challenges that need to be addressed to popularize these advanced vehicles are related to the battery. Since the early 1990s, we have been actively promoting research and development on batteries for environmentally friendly vehicle applications. Initially, the focus was on lithium-ion batteries as a potential solution to the critical battery issue mentioned earlier. Through extensive theoretical studies and numerous experimental demonstrations, we have successfully demonstrated that the potential of lithium-ion batteries exists and can be realized. This has opened up new possibilities and values that cannot be achieved with conventional batteries. This article aims to clarify the specific performance requirements of advanced batteries for EVs or HEVs, with a particular emphasis on the critical aspects of thermal design and construction for ensuring system stability. Furthermore, it highlights the significant improvements made in the power output of lithium-ion batteries for their application in HEVs.

“…Unfortunately, lead‐acid batteries have high weight/energy density ratios. Large numbers of cells lead to very heavy vehicles . Additional negative characteristics such as high degradation ratios limited the performance of early electric vehicles in terms of both range and speed.…”

SUMMARYAuto rickshaws are three-wheeled vehicles that are common in Asian cities. Because of the large number of rickshaws on the road and their older two-stroke engines, they have a significant negative impact on urban air quality. Recent changeovers to four-stroke engines as well as diesel, compressed natural gas, and liquefied petroleum gas engines have succeeded in reducing the quantity of pollution and greenhouse gas emissions. However, because of the large number of vehicles, the rickshaw "fleet" still represents a significant source of air pollution. There have been several studies that have examined the feasibility of converting an internal combustion engine (ICE) rickshaw to a photovoltaic or fuel cell (FC) hybrid electric configuration. These studies have typically used or modified a standard urban drive cycle. It is argued that such drive cycles do not accurately portray the demands on a rickshaw. Thus, the results may be misleading. In this study, a model of an ICE rickshaw was created and validated against experimental results. Two drive cycles that would closely emulate the true demands on a rickshaw operated in an urban environment were developed. A model of an FC hybrid rickshaw was created and tested. The effects of FC and battery capacities as well as the electric motor type on performance were studied. A comparison between ICE and FC hybrid rickshaw configurations was done using a realistic drive cycle. The ICE and the FC hybrid rickshaw models were created and assessed using the Powertrain System Analysis Toolkit software package.

“…Moreover, gas recombination reaction during charging acts to unbalance the state of charge among the cells. Slightly degraded cells have high internal resistance and therefore a high rise in voltage during charging, which excessively generates electrolysis and decreases of water in process [2]. There have been many techniques aimed to improve the life cycle of the EV batteries [3][4][5].…”

This paper describes the design and implementation of a novel system for control and management of the electric energy delivered to and consumed by Electric and Hybrid vehicles. Low power and high power algorithms were implemented on a reconfigurable System-on-Chip that was installed on an Electric Vehicle. This integrated circuit acquires the individual voltages and temperatures of the batteries when the vehicle is on the road and then will identify any battery(s) starting to show early signs of failure, will apply low power rejuvenation algorithm when the vehicle is off-road, and will apply high power rejuvenation algorithm when the vehicle is at a recharge station. This system will rejuvenate the whole battery pack without dismantling them nor unloading them from the EV, will extend the useful life of the batteries and make the Electric and hybrid Vehicles more user-friendlier. Index Terms -Battery Rejuvenation Algorithm, DC-to-DC Converters, Electric Vehicles (EV), FPGA, Hybrid Vehicles (HV), Sealed Lead Acid Batteries, System-on-Chip (SoC).
