on board genset?
just throwing around silly tinkerer ideas.
anybody seen these? https://www.harborfreight.com/electr...arb-63025.html one guy brought one out to a ham radio event in December and the thing was fairly quiet and efficient. one some carts, it may even fit under the body. had me thinking.. i wonder if it could be coupled to a current limited switching power supply set to battery float voltage. gonna go for a long ride, pull the rope and use it as a range extender or crank it up when you get to your location and leave it purring while you have lunch. |

Probably would be borderline on having enough current to support the charger. 700 watts is a little low but if you are just topping off it might work.

Re: on board genset?
The amount of power you could replenish into the pack using a charger of any sort would not make enough difference to really notice a change in the overall range of the pack. You would have to stop for several hours for the pack to replenish enough to have a noticeable change, assuming you are using a 15 amp charger. In which case you would need something closer to 1500w supply power) Consider that a fully depleted pack (50% SOC) normally takes around 10 - 12 hours of charging to fully recharge. If you were to use a 5amp trickle charger the charge rate is so low you would not reach a full pack charge.... ever. Making any noticeable difference in how far the cart can go would take 6-7 hours of constant charging.
The better and more efficient thing to do would be to buy a gas cart IMO. |
