When towing a ford fusion hybrid, do the regenerative brakes charge the batteries when your aux braking system activates? Or does it have also have a conventional braking system with brake shoes and such.
No, and yes.
When towing a Ford hybrid, Ford instructs you to leave ignition switch in ACC position, which means the drivetrain and regenerative braking is off. Sooo, no, the high voltage batteries do not get charged when your aux. braking system activates.
The Fusion hybrid does have a conventional braking system as well (4 wheel disc, ABS). This is what is used when your supplemental braking system pushes on the pedal.
The way the braking system works on the Fusion hybrids, is that it has both regenerative braking as well as conventional braking. Regenerative braking is only turned on, used, when driving the vehicle (not towing). Depending on how hard you brake, regenerative braking is used first, with conventional braking kicking in only if you push harder on the brake pedal and need to stop quicker.
Every time you stop, once you come to a complete stop, it shows you a 'score' of how much of your braking was done with regenerative braking. If you can anticipate your stops and brake gently more often, you use more regenerative braking that provides charge to the batteries, meaning you can run in EV mode more and get better mileage. Gentle braking definitely helps your mileage with a hybrid. If you frequently wait 'til the last minute to start braking, you will not see as good mileage with a hybrid.
This also means that the conventional brake parts (pads, rotors, etc) on a Fusion hybrid last almost forever, because they are used much, much less than they would be on a conventional vehicle.
Anyway, hope this answers your question about how the brakes work on a Fusion hybrid. We've had ours for over a year now, and absolutely love everything about this vehicle. As already said, its soooo easy to tow, IMO the easiest and most simple auto tranny vehicle there is for flat towing. Mileage is absolutely amazing, and its just really cool having a vehicle that can run silent, without burning any fuel for a lot of the time. Kinda like having a large, fast, very comfortable golf cart in campgrounds, haha.
Only downside you may not like: Check the trunk in the back. Due to the batteries it has, there is not quite as much trunk space as some other vehicles. Not an issue for us, but may be for some. For us, it 'discourages' DW from shopping and buying as much stuff, since not as much room to put it, hahahaha. :B
