SaaS AVM and electric buses: adapting your system to the energy transition

Fleet electrification is not just an HR and financial topic. It is an operational transformation that directly affects the AVM. An electric bus is not operated like a diesel: its range varies with temperature, route profile, and driving style. It needs charging, which must be integrated into service scheduling. And if the AVM cannot see this data, the operator is running a partially blind fleet.

What changes with electric buses

Range management. An electric bus has a range that varies between 150 and 350 km depending on the model, weather, and route profile. The AVM must alert the dispatcher before a bus runs flat on the line.

Charge scheduling. Electric buses must be charged during operational troughs. Depot supervision must integrate the state of charge of each vehicle: a bus pulled off charge at 30% to cover an 80 km line is an operational problem.

Onboard equipment. Electric buses are often delivered with embedded telematics systems (OBD/FMS gateway). For the AVM to consume this data, it needs an open architecture compatible with these protocols.

What Pysae addresses

Pysae is built on an open hardware architecture: Android tablets onboard communicate via ITxPT and FMS standards, enabling native integration of data from electric bus embedded systems.

Pysae's Depot module integrates a real-time state-of-charge view, intelligent charge sequencing based on departure priorities, and automatic alerts when a vehicle reaches a critical threshold. On the Elios network (Grand Villeneuvois), 100% of the fleet is green with Pysae as the supervision system.

How to prepare the migration

Three questions structure the AVM adaptation project: Can incoming electric buses be fitted with the onboard terminals of the chosen AVM? What energy data should the AVM consume, at what frequency, with what alert thresholds? How do charging constraints integrate into roster construction?
