Those of us living in the 'sticks' just have 'whole house' generators connected to our 250gal popane tanks for those pesky utility outages, and random tree falls, lightning strikes, snow loads, etc...Back on topic... I have a 750W inverter connected to my 12-volt battery that is continuously recharged from my 100KW main traction battery.
Plenty of power to recharge a lot of EBikes... or power my critical loads during a home power outage.

Yeah. It seems like it shouldn't take much to run a pair of chargers, even if I don't have a "main traction" battery, I have deep cycle style house and starter batteries that should be fine for a 2 to 5 amp draw for several hoursBack on topic...

Directly on topic. Do you know of a thread function to subordinate discussions? This 3C discussion structure has two joined, subordinate topics, i.e., eBike battery and car electrical system to support eBike charging.
Actually the comment about off topic was a joke. Very few threads on EBR stay on topic for more than half a dozen posts. Looking at your plans, I have the high top MB sprinter van converted to a camper by Winnebago before things like inverters and lithium batteries were a thing. Trying to figure out what mods I need to support two ebikes, and charging is an issue.Directly on topic. I am designing a 3C system for camper van around an eBike recharging system. Ultra-fast charging (3C) recharging time is essential to both bike and camper. Please note the J1772 connector has 10 hour recharge time at 1C. Both the eBike and camper are part of the same system. I am thinking from Tour Divide perspective in CO, at least. Both the eBike and camper need to be functional at high altitude. I want to ride over 100 miles per day. More maps.
After I think through the combined requirements, I will post the car electrical system part to another post, or start a new one. Right now, I need to keep both together, because I have not thought through the details. I have a general, but unspecified plan. I have been thinking about this for years. Being trapped due to Covid19 has forced a feasibility study. I might desperately need to escape to NM this fall or winter during flu season. March and April were bad enough in Denver.
I reached a conclusion about the Specialized Creo SL Evo Extender lacking 3C batterypack. The saving grace is the bike does require continuous power. That qualifies the Creo as a true hybrid vehicle.
Modular electrical system a la Egoe style (https://uncrate.com/nestbox-camper-module/ ).
- Camper designed around electrical system.
MB diesel Sprinter, 4WD (suspect too high for parking entrance)- Toyota Sienna AWD
- Electrical system dictates camper livability. Minimal requirements:
- Subfloor with radiant heater
- Outlets to power electric blanket and appliances
- Lighting in ceiling or walls
- Water heater
- Recharge eBike battery
- Specialized Creo SL Evo does not require continuous power.
- Small electric refrigerator
- A J1772 outlet to charge camper battery from EV stations
- 720 aH @ 12v = 60w. 72A ( J1775 80A max), 1C = 10H full charge time. 3C = 2 hours.
- How much sailing hardware is appropriate?
- Fast charging battery system:
- 540W of solar panels (3)
- 3500W Pure Sin Wave Inverter (2.5 hours of driving to recharge battery)
5kW diesel heater- eBike (2' x 6' space)
- Lighting
- Small induction stove
- Small Microwave
- Refrigerator same dimensions as stove
- Water heater for shower
- Sound system
- Internet Connection
- Heating, Cooling and Ventilation
- Tradeoff between roof exhaust fan and solar panels
- Carbon monoxide detector
I think 3C is essential. Taking advantage of EV car stations with J1772 outlet(s) allows scalability. You might consider multiple J1772 outlets.
Do you need a pure sine wave inverter or just any inverter? Probably doesn't matter unless it's a much bigger inverter, where the price jumps quickly for the better inverters.Back on topic...

I am just leaving notes to myself. I haven't investigated inverters, yet. I would appreciate your recommendations. I know very little about this subject. I am relying on theoretical knowledge. I have no practical experience. I prefer to err on the side of over, rather than, under specifying. I intend to turn the specifications over to someone to build the car electrical system for me.
There are some small problems with solar panels both roof mounted (if parked in shade to avoid heat) or suitcase style folders that can be set out in the sun (theft).Directly on topic.

I have little practical experience, but I have a couple dozen panels on my roof and two huge inverters in my garage. But they don't have to move, nor are they subject to theft. I am investigating inverters now, was originally going to use a marine dc to dc charger, but that won't work with the Specialized proprietary battery and charger.
I am assuming marine products are appropriate, but don't really know. The assumption is based on similar size constraints between boat and car. I have spent too much money at West Marine, though.
My philosophy is modular. I would like to put components in plastic milk cartons and zip tie together. I haven't done something like this before. I expect to make mistakes.
Marine products are fine (but spendy), the issue is with the specialized battery that won't charge from a 3rd party charger, hence the need to convert to 110 ac to run a charger that converts the electric back to 42 volts dc.
I am generally skeptical about any vendor tie-ins, especially electronics. I love my Specialized Diverge. The Creo is derived from Diverge geometry.
If you get tired of milk crates there are inverter/charger/power centers that are designed for camper conversions and mount to an inside wall or in a cabinet with proper cooling fans for air flow. And they are rugged enough to stand up to vibrations from highway speeds.
Thanks. I prefer to start with special purpose items, because I don't know what i am doing.
