Bus starts overcharged, and continues to overcharge #90

found while investigating #89, using the same scenario and data. See that ticket for the csv used.

Expected results:

  1. Bus is created with 220 kwh, and can only charge to 220kwh max.
  2. Bus only serves 1 trip at at time.

Observed Results: In this scenario Bus 767 appears to start with significantly higher power than 220kwh (assuming energy left is in units kwh) It also continues to overcharge, over 2000kwh at its peak. It also serves two trips with the same start/end arrival_time fields, one of which starts from a depot, another of which starts in the middle of a block. This suggests it serves two trips at at time.
