Can it be overcharged?

I am asking for someone smarter than myself, I was driving across West Virginia in my new Maverick and the grades through the Red River area are steep and long, I was wondering this? dropping into the gorge there was a period of close to 8-10 miles where the Maverick was sitting at max regen holding speed and only at the very bottom did it feel like the regen backed off a bit and i had to touch the brakes. In that situation will it stop regen if battery is full? Does it burn off the excess juice like a train engine turning it into heat? I just drove and figured it would do its thing and it did but it was a curious thought as that is a pretty extreme case of downhills. Love that regen braking it is amazing.

seems you answered your own question, regen stopped and you had to use brakes. glad you're happy with it.

There is a battery management system that controls the charging of the battery. This will not allow the regen system to overcharge the system.

When HVB gets to about 72% charge Regen braking ceases and ice will come in without fuel or ignition and will run as an air compressor. With cruise control on it will also balance engine braking and hydraulic braking to maintain set speed. It does work really well. If you manually brake that will turn cruise off. If you want to slow down just lower set speed on cruise button.

Awesome, I never felt something work so integrated and seamless, especially in the mountains

I agree.

You'll also really appreciate how long your brake pads will last. Very possibly over 100k+ miles.

The "regen" needle in the green can be deceptive.

I've witnessed the needle stays deeply in the green zone when battery is at 72% maximum and "engine brake" is going on.

In engine brake the traction motor is generating just like regen, but that wattage is going to the generator/starter motor that is spinning the engine without fuel.

The green needle may literarily be an ammeter; and since you are generating power in either case, the needle is in the green in either case.

Similar to dynamic brakes on a locomotive, but there is no bank of resistors turning power into heat.

Similar question:
Say you're going down an incline that's long, but not a really steep grade. If you aren't going as fast as you'd like, due to regen slowing the truck; if you hit the go pedal to speed up, the EV coach often still shows you are charging.
When pushing the go pedal in this situation, does it just reduce the amount of regen to reduce rolling resistance?

Yes.
The regen is completely variable based on your pedal inputs, from either pedal.

Thanks. Good to know that downhill regen can be controlled with the Go Pedal. I figured that's how it worked, but wasn't sure.
