Been driving the T8 for a week now and I was wondering, when does the recharge needle goes into the red charging zone? Does the red zone indicate higher recharging?

Congrats on your T8. Hope you are enjoying it!

The needle goes into the red area when the regenerative braking is not sufficient, and the mechanical brakes have been engaged. This happens when you press the brake harder, as regen braking is not as effective as mechanical braking, and is not enough to slow down the car.

The second question is a little harder to answer. If you assume that braking is always blended, then you could assume that once regen braking has reached it's maximum, it then applies mechanical braking. The question becomes whether the regen braking is still at that maximum level. If so, then yes, you've reached the maximum level of recharge.

The other way to look at it is, Am I recovering the maximum amount of energy from recharging? If you go into the red zone, then the answer is no. Some of the energy is lost to friction braking. To recover the most energy, keep it in the non-red zone. This means the mechanical brakes have not been engaged, and all braking is regen braking, and used to recharge.

Think of it another way. Until you get into the "red zone" you are capturing all of the available kinetic energy and recharging the batteries a little bit. Look at it another way, you are not burning brake pads until you into the red zone, and based on my now 20,000 miles of driving, that means you may never need to change the brakes in a T8 (Recharge).

If interested, any elm327 adapter will show electric motor power and regen in kW and amps, and the charging rate:

Thanks everyone for the feedback and interesting comments(y)

Like the idea of saving the brake pads .. I try as much now to let the T8 coast and maximize the regen braking. Also using 'B' gear when appropriate.

I have an elm327 adapter but haven't gone about using it yet ... still exploring and getting to know the T8. So much to learn

On my Nissan Leaf, my brake pads didn't got worn from normal usage (I almost never use it except at low speed when stopping as regen is not doing it).

They got worn by staying stuck in the callipers because of not moving enough. Even if I try to use it strongly at least one time per travel and despite putting grease on callipper rods every 2 years.
I will do it now every year at least.

Quebec salty winter roads rule.....

Maintenance is key

I use "B" mode 100% of the time. One item you might not realize. There is in the "climate" section of the system for an "additional heater" to be clicked on. When you do that the heat works great when you are in EV mode from the start without the ICE starting up. My experience has been that until the ICE engine starts and the traditional heating system kicks in, the vehicle does not warm up inside on cold days, unless this "additional heater" is clicked on. The downside of this heater is the EV range is shortened. Thus what I do is when I first put the vehicle into drive in hybrid mode, I depress the throttle enough to get the ICE engine to fire, then switch it back into pure mode as I pull away. The ICE engine is running to warm up, but I am generally not getting thrust from the ICE engine, just the EV motors if I am lighter on it. I get heat within 90 seconds or so, and then it lessens the battery degradation too. Just a user tip that might be helpful. I hope I am describing things in a way that makes sense. I'm at 57+ mpg on this tank and have gone more than 450 miles, still well over the 1/2 tank mark on the fuel gauge. Mostly local short driving FYI.
