Is anyone familiar with BEV vehicles running 100% recirculation at low ambient temperatures?
I understand that eHVAC have a big impact to BEV range when its cold and running 100% recirculation is less energy consumption compared to 100% fresh air, so it seems like there is a motivation to do...
i think this should be simple electrical question, but have been stuck reviewing electrical books and internet searches on this one...
let's say i have a bank of 10 batteries and am drawing 10A from those batteries. no matter how i configure the batteries i should be drawing 1A from each...
My understanding is that Automotive Power Electronics are typically designed with levels of power electronic components ie 650V, 1200V, 1700V, mosfets etc... and if you have 1200V components you typically need headroom and dont operate the device at 1200V, usually a couple hundred volts lower...
are there any general rules of thumb concerning inverter/motor efficiency across a voltage range?
for example if we are looking at a range of DC input from 400-1200V, and we assume inverter/motor can be optimized for any voltage input, is there any overall efficiency benefit of a higher voltage...
How would one be able to continuously use two 12V batteries in series (to create 24V) and also charge with 12V charger?
thinking about automotive application where i'll be using a 24V load and simultaneously charging with 12V. What components and wiring solutions can achieve this?
Thanks!
