Making electrical drives plannable
A single battery charge is not enough for the typical daily route of an electric bus. Therefore, the energy available in the battery must be taken into account when planning the bus rotations, so that it is guaranteed at all times that the battery is not completely discharged. The energy requirement of a vehicle does not only depend on the distance covered, but also e.g. also from the height profile of the route, the ambient temperature and the speed of the vehicle.
Also charging the battery is a complex process that depends on many factors and, above all, can only be carried out in locations with the appropriate infrastructure. Important factors here are the charging technology used, the charging current and the battery charging level. In addition, the capacity of a battery changes over time, as it decreases with the number of charging cycles performed.
A basic distinction is made between the following charging strategies:
- Depot charging / overnight charging: the vehicles are charged during the shutdown in the depot,
- in motion charging: the vehicles are charged while driving as a trolleybus,
- Opportunity charging: the vehicles are charged during operation by fast chargers at bus stops or in parking facilities.
In addition, we support several transport companies in testing ES-OPT so that they can use their electric buses as efficiently as possible.
