“…The VRLA battery has a low energy density of 38.7 Wh/kg, whereas the LFP battery has a higher energy density of 117 Wh/kg, making it lighter and safer for users. hydrocarbon (HC), nitrogen oxides (NOx), carbon monoxide (CO), and particulates (PM), which are predicted to increase significantly [1]. Several countries in the world, including the UK, China, France, Germany, Ireland, and Norway, have plans to ban the use of fossil fuel vehicles (gasoline and diesel) by 2040 [2].…”

The depletion of fossil fuel sources and the increasing environmental pollution caused by the burning of motor vehicle fuels are major problems worldwide that need to be solved. One of the promising solutions to overcome energy security and environmental pollution is the use of electric vehicles. E-bikes are one of the most popular electric vehicles because of their many benefits. A valve-regulated lead acid battery (VRLA) is now the most common energy source for electric vehicles. It is heavy and unsafe for the user due to its poor energy density. Lithium ion batteries may be a feasible solution. One type of Li-ion battery that is environmentally friendly is lithium ferro phosphate (LFP). The potential that exists encourages researchers to conduct research and compare the performance of VRLA batteries with LFP batteries. The data retrieval method is carried out using the Arduino data logger application and is equipped with a microcontroller to read current and voltage. The test results prove that the LFP battery has good voltage stability. The distance that can be traveled is quite long, which is up to 50.16 km, because it is supported by a large capacity. On the other hand, VRLA can only travel 37.83 kilometers. Furthermore, the energy density of LFP batteries is great. The VRLA battery has a low energy density of 38.7 Wh/kg, whereas the LFP battery has a higher energy density of 117 Wh/kg, making it lighter and safer for users.

“…The world is dealing environmental pollution issues caused by exhaust emissions,including hydrocarbons, nitrogen oxides, carbon monoxide, and particulate matter from vehicles using traditional fuels, such as gasoline and diesel, and these were expected to significantly increase by 2020 (Pielecha, Merkisz, Jasiński, & Gis, 2015). In recent decades, the emphasis of urban transport policies has been placed on developing sustainable transportation strategies in a way that protects the interests of future generations.…”

In addition to the environmental problems that have plagued human life in recent decades, the outbreak of the coronavirus epidemic has endangered people's health and adversely affected their lives in other ways. Therefore, the present study aimed to investigate the advantage of using shared bicycles (SB) during the outbreak of epidemics. For this purpose, 310 male subscribers of an SB system were examined. The research tool was a questionnaire taken from studies. The results showed that the environmental and health advantages were favourable, but the place advantage indicated a relatively unfavourable situation. The results of the structural equation model also showed that the advantages of using an SB based on the highest impact are the motivational advantage, health advantage, environmental advantage, social advantage, financial advantage and place advantage. These results can provide useful solutions for governments to reduce environmental risks and maintain health and physical activity during epidemics.

“…Studies in road traffic conditions draw attention to significant emissions of particulate matter, mainly in nanoparticle range from combustion engines also those powered by alternative fuels (e.g. natural gas) [17]. The article also emphasizes considerable mileage of the vehicle using alternative fuels, which in turn causes an 8 times increase in emitted particle number for vehicle with a mileage of 500,000 km compared to the vehicles with mileage of 75,000 km.…”

The article compares driving test data using the latest legislative proposals applicable to passenger cars with different drives. For this purpose, cars of one type were selected, meeting the same exhaust toxicity standard (Euro 6c) and differing in used internal combustion engines (with spark-ignition, compression-ignition and hybrid drive). Several measurements were performed on the same test route in accordance with the RDE test guidelines, which requires a several of criteria to be met. These criteria include the length of the measuring sections, their overall timeshare and the dynamic characteristics of the drive. A portable emissions measurement system (PEMS) was used to record the engine and vehicle operating parameters and to measure the exhaust emissions during tests. This allowed for the monitoring of parameters such as: load value, engine speed and vehicle velocity. Then the obtained results were analyzed for their compatibility with the RDE procedure requirements. By determining the road emission of individual harmful compounds for all vehicles and the dynamic parameters of drive (relative positive acceleration and product of speed and positive acceleration) in various phases of the road test it was possible to compare them. On this basis, the impact of dynamic conditions of road tests on the obtained results of the road exhaust emission of harmful compounds for passenger cars with various drives was defined.
