SPIRIT-E is a research project aiming to accelerate the electrification of the transport sector with battery electric trucks (BET), their bidirectional integration and a reservable shared usage of private charging infrastructure. Funded by the German Federal Ministry for Economic Affairs and Climate Action, the project objectives are developed by eight consortium partners with broad expertise over the whole ecosystem of transport electrification. The main research goal is to quantify the economic potentials of integrated truck operation and bidirectional charge management and evaluate the effects for road transportation and energy grids. The final product will be demonstrated in real-world laboratories at logistics sites.
