Questions related to Light Electric Vehicles
Up to date, what is the rated/maximum power of different electric vehicles on the market (if possible, can list some examples)? And how is the development trend in the future?
I want to optimize the usable SOC range of hybrid vehicle in order to improve fuel economy. So. how to choose maximum and minimum SOC values for running an optimization algorithm?
What parameters should be metered?
What are the other considerations?
Remote monitoring?
Relevant sensors?
Relevant mathematical tools?
What should be the multidimensional nature of EV charging station in urban and rural areas?
Hello all,
By modifying the PWM of the CP signal, I can change the charging current of Electric vehicles in AC charging.
But how the current is controlled/reduced accordingly? Which side does this current control?
Does charging station (EVSE) supply the corresponding charge current? or EV controller in the vehicle side reduces the incoming current?
Any literature/references/docs/links will be useful. I tried searching, but couldn't find how the current is controlled/reduced

Which types of electromobility or alternative solutions for the environmentally-friendly supply of motor vehicles are being developed in your countries?
Are they based mainly on purely electrical or hybrid engines that connect electric power with petrol or other, or power based on the combustion of hydrogen with oxygen?
Please reply
I invite you to the discussion
Thank you very much

Does anyone know the heat release from 48 V, 10 kWh Lithium battery module? This is to know what happens during Abuse testing
The energy density of most redox flow batteries is too low for transport solutions but there is a Swiss company: NanoFlowcell that claims their QUANTiNO vehicle accomplished the impossible.
“The low-voltage system in the QUANTiNO works with the nanoFlowcell® drive to form an exceptionally efficient symbiosis that promises a significantly greater potential range compared with the HV systems commonly used in electric vehicles. Furthermore, it eliminates the danger of electric shocks that can be caused by a high-voltage system in the event of an accident or when undertaking repair work to HV components.”
Only data provided by the company are the test run results. Calculations based on this data gives following results:
Energy demand: 13 kWh per 100 km
Energy density: 600 Wh per liter or kilogram
Average test run speed = around 23 kph
A full tank range at this average speed: 1,400 kilometers.
Nowadays, conventional flow batteries based on vanadium sulfate theoretically achieve energy densities of up to 19 to 38 Wh/L with respect to pure electrolyte solutions. Bromine-based systems would achieve 70 Wh/kg.
It sounds like redox flow cells are not an attractive option, as not one of these cells reaches the levels of lithium-ion ones. Maybe I’m missing something? Did anyone had contact with this compay and can can confirm their results?
Maybe somene who works with redox batteries could share his opinion?

Electric cars and hydrogen cars both run on apparently clean fuels. However, the source of electricity or hydrogen production may be based over partially clean processes. It is a question of the future, which of them will prevail.
I am developing a model which predicts the average energy consumption of electric vehicles in various climatic conditions. I found the average requirement is 400 W/s at 25 degrees and the power requirements increases as the temperature goes down. But what is the proportionality between these parameters?
Hello,
Currently one can estimate the ageing cycles (charge+discharge) of EV. Does anyone know how much is the cycle is vehicle2grid facility is introduced ? This number can be for any EV as example.
Any links/references will be useful.
Thanks,

Why automotive industry is feeling new powertrain architecture for Electric Vehicles? What are the benefits?
mems, accelerometer , gyroscope, mems sensors in electric vehicles.
Hi,
Anyone knows where I can get sample EV's drive cycle data like mentioned in the picture ? I will need time,current,voltage values.
I want to select a motor for electric vehicle.
Im performing a videographic survey in an expressway to estimate the emission of line source. But to determine emission load of a vehicle, I need a data on vintage of that vehicle. Any possible way to estimate vintage of vehicle from the videographic survey?
Vintage of vehicle: year of manufacturing.
Dear colleagues,
As a part of the Electric Vehicle Battery Swapping Station - EV BASS (http://evbass.fer.hr/en/evbass) , we have prepared a short online questionnaire on EVs. I kindly ask you to take five minutes of your time and contribute to this project, which will help us better understand the needs and habits of the prospective EV owners. The questionnaire is available at https://www.surveymonkey.com/r/ev_bass Thank you for your time.
I want to analyse market share of electric vehicle in present and future situations. For my base work.
I want to know a real time practical example of vehicle to grid and grid to vehicle. Is there any country that has taken any initiative in this area of research?
Are Series or Parallel configurations given in advisor useful to build our own model of any configuration?
Does these types of models exists, or has anyone ever modelled such a configuration? If yes, is it available ?
If not, would you have an idea of what is the best way to model it? Starting from series?, parallel? or any other configuration?
I am looking for free software to simulate the PMDC motor for my electric vehicle.
