If you are driving a Volt, you might know there’s only a small overflow buffer above the "full charge" battery SOC level. If you live at the top of a hill and start the day with a full charge, the downhill regen at the start of your daily drive quickly fills that buffer, and braking must be accomplished by other means because the battery is at its maximum allowed SOC level. (And, once you can’t put any more regen into the battery, reports indicate that distances are recorded as Gas miles/km. I suspect this is because conditions no longer meet the criteria for Electric Mode driving.) Not sure if Gen 2 has modified the propulsion configuration to avoid this problem.
You have options:
Use delayed charging to set the "full charge" time target to a time after you normally depart, so the car is not yet fully charged at your normal departure time.
Unplug the car in the morning, then use remote start to precondition the car, setting the climate controls for extra heat (or extra cold air conditioning?), producing power consumption prior to departure, leaving more upper buffer room for regen as you head downhill.
Perhaps if you start blasting out the heat (or air conditioning) as you start your drive in the morning, the power draw for the cabin heating/air conditioning will consume enough of the downhill regen to prevent the overflow buffer from being fully filled by regen. If this creates an uncomfortable environment in the cabin (too hot, too cold), you can always open the windows...
