I'm sure this is "by design", but does anyone know why. I've only had this happen twice since I picked the van up. I'll have plenty of electric range left, and have to brake hard, and the engine kicks on. Both were like 15 mph to zero emergency stops. Thoughts?
This is kinda it. The vehicle is set up for comfortable driving, so if you are driving to the limit via pedal down or hard braking, the vehicle assumes in the next instance you're going to need extra power for whatever reason. So the gas motor comes on as a precaution "incase" you need the extra power or more direct control of the vehicle. Hard braking usually means you or somebody ****** up on the road and you need to get yourself out of a tight situation, its best to have maximum power in case you need it.I had engine kick on during a period of heavy regeneration going downhill - I figured it was perhaps in regards to head dissipation due to the very large load the battery can be under during regen (I've seen -84kw in some instances)
