# This simulates a 70 % charge limit with the scheduled charge time set to currentTime + 2 minutes. The initial fake
# status is "75 % and charging InProgress". First, ChargeControl should stop the charge.
#
# The fake status then changes to "75 % and charging Stopped, but still plugged". Since the scheduled charge time is
# only 2 minutes away, ChargeControl postpones the charge to the next day. It does so by setting the scheduled charge
# time to (currentHour - 1):00. For instance, when it's 14:21, it will change the scheduled charge time to 13:00,
# which has to be on the next day.
#
# For reference, here is a correct sample output:
