List of assumptions and implementation details

• total cost is the sum of grid cost and battery degradation cost for each interval
• battery degradation formula has been re-adapted to reflect that the cumulative sum has to be 1 over time:
  • degradation = (abs(energy_flow_kwh) / capacity_in_kwh ) / (rated_cycles / 2)
• for costs, Decimal is used as data type instead of float for better rounding & arithmetics
• energy interval is assumed always the same in the energy flow table
• energy tariff are the same when either using or selling grid's energy
• energy tariff are given as Weekday / Weekend and through time intervals (refer to energy_tariff.json)
• energy tariff are applied taking using only the start of the time interval

python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt
pip install -e .

• complete all the steps in setup
• run (with default parameters)

  python cost_calculator.py

• to print a list of possible parameters use:
