96v BMS and Charging system - Need Help / Advice
This is for a Electric Boat - More info on this thread.

As all my past experience has been with House Solar, I have been gravitating to similar equipment, I am quickly learning though there is an entirely new world in the EV space better suited.
My knee jerk was Each 32s Battery would have its own 32s 200amp BMS. The 3 packs in parallel would then be hooked up to a 96v Inverter/Charger. This is current Plan.
Thanks

96v Solar Cabin Cruiser Project - Full...
Starting this thread to document the full Solar Boat Conversion Project. Always looking for good advice. The Concept 1) I will eventually be converting a nice 40 Cat or displacement Hull to Electric. Needed a project boat to experiment on first. 2) I found this 23 foot boat for $1800 +...

- There will be 85kWh of LifePo4 Batteries. 96 cells
- I was gravitating to 3 32s 96v Batteries that would be ran in parallel. Would allow 3x redundant. 2 packs could be taken off line if needed. (THIS CAN BE CHANGED)
- The EV will have a standard Split Phase 50amp 240vac Shore inlet as power source.
- NOTE: Depending on where parked. Shore power may only offer 30amp 120v or 15amp 120v service.
- Charger needs the ability to work with both.

- UART RS485 communication BT 3s-32s 10A-200A BMS used for li ion lifepo4 LTO battery cells
- 12v 24V 48V 96V dc to 220V 110V ac 1kw 2kw 3kw 4kw 5kw 6kw 7kw solar inverter with charger
- These are unproven likely not very robust parts made for Solar setups
- I feel like there are robust proven EV solutions for 96v
- Will not utilize the full 50amp 240vac Shore hookup - will max out at ~2500 ish Watts charging
- Sadly, I do not even know where to begin help me!!!
- Basic research suggest there are systems where the charger talks to each Battery BMS.
- would this work with 3 separate packs in parallel?
- How would the charger hook up to a 50amp 240v split phase breaker box vs EV Charging station inlet
- Would the charger be able to handle power if it was only 120v. (30amp shore power or 15amp shore power) how would it know to step down?
- See such great potential here and do not want to try to re-invent the wheel as this 96v setup must be basic in the EV world
Thanks
