electric vehicle

Hi all, I am appealing to the wisdom of crowds and our AAC community. According to one published report I found, EVs accounted for just under 5% of car sales in the US in early 2022. So, I am curious. When do you think EVs will surpass 50% of all US car sales? I would also love to hear your...

Hi guys, My company assembles electric motorcycles and mopeds. We are considering launching our own electric motorcycle line up and I noticed EV's are very silent despite the reduced noise levels this is impacting pedestrians on busy streets especially in India where majority of people don't...

Hello Everyone, I am currently working on a 2.5kW PSFB converter using UCC28950 ic from TI in TINA simulation (unfortunately couldn't get a similar model for LTspice). The simulation is working however I am not getting the desired results (i.e. Vout = 84V and Iout = 30A). I have a uploaded a...

I'm working on building an electric scooter and yesterday the speed controller had a MOSFET failure that I suspect was caused by inductive spiking. This was very surprising to me because I had a schottky diode in parallel with the motor to prevent this type of failure. I took the speed...

Hello everybody I'm going to simulate a Lithium ion battery whose no load voltage depends on its DoD (DoD=1-SoC). I used the book of Soylu in which he obtained a 10th order polynomials for no-load voltage of the battery...

My application is the EV powertrain. Most commercial electric vehicles tend to use film capacitors as high as 1000 uF or even more (link: https://info.ornl.gov/sites/publications/files/Pub26762.pdf). In this document, evaluation report of 2010 TOYOTA PRIUS is presented. The attached figure shows...

Hello all! I am currently conducting my thesis research. My aim is to determine the most efficient way to combine high power density batteries with high energy density batteries in an hybrid system for powering electric aircraft. The idea is by using two different types of batteries which are...
