Regen *stops* when friction brakes are engaged
"I was investigating a way to have the SOC meter tell you more directly when the friction brakes were employed. I think I found three signals indicated in the service manual. Target braking force, Regen Braking Force, and Brake Pressure. Here is a graph of a simple test where I pressed the brake pedal three times at the beginning while I was at a standstill, accellerated, then slowly increase brake pressure until I stopped. I repeated again but increased braking more slowly.
What is interesting is when you start to engage friction braking, regen is turned off. They do not simply add friction on top of regen. I guess they couldn't get the feel smooth enough. So it tells us it is VERY important to avoid friction braking because you waste *everything* once you go there - not just an incremental amount above the regen capability."
