CHAMPPy - Mobility and Charging Profiles in Python

CHAMPPy

CHAMPPy (Charging and Mobility Profiles in Python) is a Python library to generate synthetic mobility and charging profiles for different types of electric vehicles (EVs) including vans 🚐, trucks 🚚, busses 🚌 and passanger cars 🚗.

Road transport decarbonization requires realistic charging demand models across all vehicle classes. However, most existing studies and publicly available tools focus on private passenger cars. Commercial electric vehicles such as vans and trucks are often underrepresented despite their major relevance for emissions and grid impacts. CHAMPPy is an open Python package that addresses this gap by generating synthetic driving and charging profiles for different EV types, including commercial fleets. The model combines a Markov chain to represent vehicle locations over time with beta-distributed journey speeds, from which trip distances are derived, and uses dedicated algorithms to generate mobility and charging profiles. An optional clustering approach increases profile heterogeneity and is particularly useful when analyzing individual profiles.

🛠️ CHAMPPy supports two workflows:

1. Light: Use existing parameters to quickly generate drving and charging profiles with user-defined settings (e.g., simulation period, number of vehicles, charging power, battery capacity).
2. Full: Re-parameterize the model with custom reference data (e.g., other countries, fleet compositions, or vehicle classes). Generate drving and charging profiles from your model parameters.
