I'm hoping to build a compact charger to store onboard my e-motorcycle conversion. My pack will be something like 12 kwh. Even with a pair of 1000 watt meanwells (or meanwell clones) it will take ~6 hours to charge.
I'm aware this is probably a stupid question, but: How difficult is it to just build a rectifier with current control for this purpose?
I'm looking more for suggestions on where I can learn how to solve the challenges here. For example, I'm not sure on how to chose appropriately sized capacitor and inductor for doing the output filtering, and I'm a little bit unclear on how I should handle the current sensing and PWM to do the current control. Probably this is way more complicated than I imagine but a friend is encouraging me to try to learn.
Other challenges: Figure out voltage switching so it will work with 110vac, 220vac, and those new fast charge DC charging stations. I guess I would start with something that's just made for 220v, as that's probably the most commonly available. And how good does my filtering have to be to avoid spikes/ripple tripping my BMS high-voltage cutoff or damaging my battery?
