I hope someone can/will answer this. I don't know where else to go.
Picture a converted pickup (e.g. Ford Ranger). With on-board battery pack it would have 20-30 mile range before it needs a re-charge.
Would a gas powered generator mounted in the bed and wired into the system be able to provide enough power to keep the vehicle running and re-charge the battery pack while driving. Run the generator until the bp is recharged and then turn it off, until the next re-charge?
Has anyone tried this, or know of anyone who has? Did it/would it work?
Thank you for the answer. Wow, I hoped I would eventually get an answer, but I certainly didn't expect one so quickly!
Several years ago I saw an article in Mother Earth News about a gas-hydraulic drive vehicle that got near 70mpg. Short version: a 16 hp gas engine, running at its "sweet spot" (most efficient rpm) powered a hydraulic pump which fed into an accumulator. When the accumulator was fully charged, the gas engine shut off.
The hydraulic pressure in the accumulator was used to power a hydraulic motor attached to the auto's differential to drive the vehicle.
When fully charged, the accumulator had more than enough stored power to start the vehicle (a VW bug) from a stop and accelerate to cruising speed. Once at cruise speed, when pressure in the accumulator dropped to a preset level, the gas engine/pump assy. would kick in. At cruise, the engine/pump provided enough power to power the vehicle AND recharge the accumulator.
The accumulator gets fully charged - engine/pump shuts down - hyd. motor runs off of accumulator pressure - pressure in accumulator drops to the preset level - engine pump starts up to recharge accumulator - repeat as necessary - ...
I started to do one of these conversions and got as far as pricing parts and found out that hydraulic components are stinkin' awful EXPENSIVE!
So, I wondered if the same concept would transfer to EVs for a little less cost (I actually hoped for a LOT less cost), but it seems not. My reason for thinking about this in the first place was to be able to take an extended road trip. The idea of stopping to recharge the batteries with a small generator is something I'll be pondering.
Again, thank you for the info.
