Hi all,
I’ve got an electric school bus I’m converting to a motorhome. I think I have a rough idea of the system that I want but I’d like some advice/opinions on if you think it’ll work and how to possibly make it better.
The bus has 105kW (400v) of Traction batteries and an onboard AC charger that takes up to 19.2kW @ 240v. I currently don’t want to mess with the high voltage system directly so my idea is to charge the bus via the onboard charger, directly from solar and a split phase inverter, after my 48v house batteries are full. Below is the proposed system:
2018 Lion Electric School Bus:
400vdc 105kW Traction Battery
12vdc Accessory Battery
J1772 L2 240vac Onboard Charger (max 80a)
Input:
48vdc 3.3kW Solar
240vac 50a Shore power (occasionally)
Solar storage:
48vdc 200ah (9.6kW) LiFePo4
Output:
120v (for appliances)
240v (to charge Traction Battery)
12vdc (for lights and to charge Accessory Battery)
The inverter I’m looking at is the MPP LVX6048. My plan is to output @ 240v split-phase to a breaker box and pull 120v for the appliances from there. Not sure where I’ll pull the 12vdc from right now but that’s a low priority.
I’m know I’m not going to get a quick charge for the traction batteries, it’ll still take days, but it’s all icing as far as I’m concerned!
What do you think? Possible?
