Route-based charging is a charging strategy where an EV’s charging plan is designed around a specific route schedule—including distances, stop locations, dwell times, and service windows—rather than charging whenever convenient. It is commonly used in fleets with predictable operations (delivery, service vehicles, buses, ride-hailing shifts) to ensure vehicles have the right state of charge (SOC) at the right time while minimizing downtime and energy cost.
Route-based charging combines route planning with charger availability, power limits, and pricing rules to make charging an operational step in the route workflow.
Why Route-based Charging Matters
Route-based charging helps fleets and operators:
– Maintain vehicle readiness and avoid mid-route range issues
– Reduce charging downtime by using planned dwell windows
– Lower energy costs by shifting charging to off-peak windows when possible
– Prevent depot congestion by scheduling vehicles across available chargers
– Improve fleet charging ROI by reducing unnecessary infrastructure and peak demand
– Support high-utilization operations where vehicles must keep moving
For shared or public charging partners, it also helps predict demand at specific sites and times, improving capacity planning.
How Route-based Charging Works
A route-based charging approach typically includes:
– Route energy forecast (kWh needed for the route, plus a buffer)
– Planned charging windows based on dwell time:
– Overnight at depot
– Between shifts
– During loading/unloading
– At terminals or hubs
– Charger selection based on power, connector type, and reliability
– Charging schedule or priority rules to ensure critical vehicles charge first
– Controls to keep site demand within limits using load management
– Monitoring and adjustments when real-world conditions change (traffic, weather, delays)
Typical Use Cases
– Last-mile delivery: charging around warehouse returns and sorting windows
– Bus depots and terminals: overnight charging plus terminal opportunity charging
– Service fleets: charging between appointments and at predictable rest locations
– Ride-hailing: charging around peak demand windows and driver shift patterns
– Municipal fleets: charging around daily duty cycles and parking locations
Infrastructure and Software Needed
Route-based charging usually relies on:
– Fleet telematics and SOC monitoring
– A charging management platform (often OCPP-based) with scheduling and reporting
– Charger availability and fault monitoring (uptime)
– Depot energy management / dynamic load management
– Optional integrations:
– Route planning tools
– Workforce scheduling
– Energy tariff data and demand charge signals
KPIs Used to Measure Route-based Charging Performance
– “Ready-to-go” rate: vehicles reaching target SOC before departure
– Charging minutes per route/shift and impact on utilization
– Peak site demand vs limit and effectiveness of load management
– kWh delivered in planned vs unplanned charging events
– Charger queue time at depot or hubs
– Cost per km and energy cost per shift
– Failed sessions and downtime impact
Common Challenges and Risks
– Winter range reduction and HVAC loads increasing kWh demand
– Route variability (traffic, detours) causing unplanned charging needs
– Charger downtime disrupting planned schedules
– Limited dwell time at stops that are assumed to be “charging windows”
– Site power constraints requiring careful prioritization
– Driver behavior variation (plug-in compliance, early departures)
