abstract = {In the automotive industry, a battery management system’s
state prediction algorithms can change during the
development cycle of a car. Monitored aggregated customer
data thus includes inconsistent state of health values which
have been generated by different algorithms. To facilitate
comparability over the collected data, databased models can
be trained on selected input variables to provide reference
state of health values. This study aims to generate virtual
customer driving data of mild-hybrid electric vehicles using
automotive simulation models and stochastic customer driving
profiles in order to establish a simulation database for
model training purposes on one hand and to conduct lifetime
simulations for new vehicles in the market on the other.
Mapping algorithms between load profile libraries and
derived statistical features from a field customer database
ensure a realistic representation of individual customer
driving behavior. We validated our toolchain using collected
trip data from a testing fleet and checked for statistical
plausibility of the simulation data. Moreover, lifetime
simulation results of selected customers show significant
differences in aging implications due to individual driving
behavior and environmental conditions. Therefore, during a
10-year simulation, the average aging rate per driven
kilometer of an Asian customer is about $33\%$ higher
compared to a European customer.},
