“…EVs operate very quietly, particularly at low speeds, and therefore are a potential hazard to other road users [58], especially pedestrians, cyclists, and horse riders, with studies highlighting that the risk of incidents with pedestrians increases by up to 80%, due to EVs or hybrid vehicles [59]. Therefore, products have been developed known as 'Acoustic Vehicle Alerting Systems' to alert road users of a nearby vehicle, by producing a sound whilst the vehicle is travelling between 0 and 20 mph [59].…”

“…However, for an electric retrofit, the vehicle has not initially been designed to carry an electric drivetrain, and, therefore, if not considered, it may affect the loads on the chassis, which could cause structural damage at a later date, as well as adversely affect dynamic handling and braking. Additionally, due to the size and mass of the batteries, they can pose a mechanical hazard, so, therefore, it is necessary for them to be fixed in position using appropriate mounts or clamps, preventing potential instability of the vehicle [58].…”

“…Safety during maintenance is another aspect to be considered, with suitable protection provided to the user, who may undertake basic maintenance work, whilst vehicle technicians and repair personnel must be adequately trained to ensure complete safety when adjusting and replacing parts [58]. It is necessary to include, within regular maintenance, testing of the insulation resistance of HV parts and testing the leakage current controller function, as well as checking battery condition [58].…”

Electric vehicles have zero tailpipe emissions and can reduce greenhouse gas emissions by up to 90% compared to internal combustion engine (ICE) vehicles. Electric retrofits involve converting an ICE vehicle to an electric drivetrain, aiding the transition to zero emission vehicles by adapting current vehicles and, thus, reducing the transport sector emissions. Other benefits include charge exemptions in major cities, reduced driving costs, and lower maintenance. The UK has a considerable retrofit market, with a large price range of services offered. There is a varying level of practice undertaken and current regulations may not adequately cover these retrofits. Industrial engagement has highlighted the varying levels and common themes of practice, such as restoration work, computer-aided design, and finite element analysis. Converting the registered fuel type of a vehicle to electricity, post-retrofit, appears to be a limited process, with few steps. Therefore, a regulatory framework, such as an accreditation scheme, could be introduced to ensure high levels of safety and good practice. Future work suggestions include further meetings with the DVLA and DVSA, and meeting the Motor Insurers’ Bureau.

“…Current research in this area becomes even more relevant in the context of the development of autonomous transport and the achievement of fully autonomous motor vehicles [5,6]. The article [7] outlines the key issues involved in the development of hybrid and electric vehicles, issues unknown to conventional vehicles with internal combustion engines. The growing number of electric and autonomous cars [8], which operate quietly and with minimal vibrations, requires a reevaluation of safety factors.…”

The process involved in preparing driving simulator tests is a labor intensive one, and the nature of this complexity depends on the sophistication of the tests to be carried out, as well as the number of participants. Which has an impact on the duration of the research itself. The very solution of using driving simulators is a research tool that has been in use for many years and with great success. They are used in a very wide range of areas of human functioning. They replicate in a very realistic way the conditions that can occur in the external environment, offer the possibility of repetition of particular conditions and insight into certain behaviors that could be very difficult to initiate in real life. This article also describes the dis- ease of using simulators to conduct research activities, along with the workflow from assumptions to finalizing the research. An algorithm is also presented for the study of individual participants, with examples for separate research scenarios concerning driver behavior in the vicinity of pedestrian crossings.

“…The users of BEVs are offered many different benefits, such as the possibility of free entry into city centres, free city parking, or the possibility of using bus lanes. However, apart from many such benefits, the users of electrical vehicles are also aware of their disadvantages [36]. One of these is undoubtedly their limited range on a single battery charge and the resulting need of route planning [4].…”

Electrical vehicles have the ability to partially recover some kinetic energy during braking. Kinetic energy is transformed into electric energy, which is fed to the battery by the control system and stored there for further use. The aim of this paper was to analyse the levels of energy recovered by an electric vehicle during braking at various speeds and with different braking intensities. The first phase of testing consisted of vehicle braking tests in real-life conditions. The registered speed profiles were then used as input data for the simulation software. The authors have also analysed the effect of the state of charge of the battery and of the vehicle’s load on the amount of energy recovered during braking. The performed simulation tests demonstrated that the level of recovered energy is significantly affected by the initial braking speed and by the force of pressure applied to the brake pedal. The amount of recovered energy is less affected by the state of charge (SOC) of the battery and by the vehicle’s load. Energy regeneration during braking is currently an important research topic. The efficiency of an electric vehicle depends on the range, which can be extended thanks to the additional energy recovered during braking maneuvers. The presented preliminary simulation results are intended to assess the level of energy recovery in electric vehicles. The authors are aware that a full, comprehensive analysis requires additional research using electric vehicles that will verify the results presented in the paper.
