Converting a Three-Wheeler Cargo Fleet to LiFePO4

Three-wheeler cargo fleets running dense last-mile distribution usually start from petrol or lead-acid traction, where energy cost per delivery kilometre is hard to forecast, roadside refuelling eats into every shift, and heavy payloads in stop-start traffic place sustained load on the drivetrain. This scenario sets out the traction configuration we quote for that duty cycle: Origin Drive Future LiFePO4 packs with depot charging, output derated rather than cut off at low state of charge, sized to the vehicle controller envelope and mounting bay.

Illustrative application scenario, based on the requirements we quote for. It does not represent a named customer or a completed reference project.

E-Mobility · Three-wheeler cargo

A last-mile distribution duty cycle built on three-wheeled cargo vehicles: depot-based operation, high daily mileage in dense traffic, frequent stop-start cycles, and sustained drivetrain load from commercial payloads. Charging happens overnight at the depot rather than on the road.
Converting a Three-Wheeler Cargo Fleet to LiFePO4
Constraints

What this site limits

  • Cargo duty draws higher continuous current than passenger use: thermal design is set by the hill-and-load case, not the flat-road one
  • The pack has to fit the existing cargo box aperture and mounting rails
  • Chassis, controller and charging arrangements are fixed by the operator, so the pack adapts to the vehicle rather than the reverse
  • Route length and payload differ between drivers, so sizing uses the loaded worst case
  • Vehicles are in revenue service, so conversion happens inside planned downtime windows
Application scenario

The challenge

Three-wheeler cargo fleets on petrol engines carry a per-kilometre fuel cost that is hard to forecast, and roadside refuelling adds a detour to every shift, which makes route planning unreliable. High daily mileage in dense traffic means frequent stop-start cycling, while heavy payloads place sustained load on the drivetrain. Lead-acid traction banks are often trialled first and typically fall short of a commercial duty cycle: the banks add excessive weight, degrade quickly, and cannot deliver the torque needed for loaded hill starts or ramp approaches when partially charged. Without a reliable range indication, crews route conservatively and leave capacity unused. What this duty cycle needs is a traction pack that carries a commercial payload through a full shift, charges overnight at the depot without specialised labour, and can be serviced locally.
Application scenario

Our solution

For this duty cycle we supply the YD-TR-7240 LiFePO4 traction pack, a 72 V / 40 Ah unit built on prismatic cells with a 3C peak discharge rating to handle loaded hill starts. Packs are housed in a reinforced steel case with shock-absorbing mounts suited to unimproved road surfaces, and the BMS provides a CAN interface to the vehicle controller so state of charge, available power and fault codes reach the driver’s display. The BMS applies a derating curve rather than a hard cutoff as the pack approaches low state of charge, so a route can be completed instead of being stopped on a ramp. Depot charging uses the YD-CH-1500 charger with staggered scheduling across the fleet, drawing power mostly overnight and avoiding demand charges. Vehicles keep a mechanical bay so a pack can be removed for a service swap. Packs are specified for a 3–5 year service life and are offered to target standards: UN38.3 / IEC 62619 / CE / RoHS. Configuration support covers workshop training on pack diagnostics and cell-level maintenance, and packs can be supplied as a pilot batch before a fleet-wide rollout.
Application scenario

What this configuration supports

This page describes how a configuration of this kind is specified, not a delivered installation. The derating curve keeps usable torque available at low state of charge, so loaded hill starts and ramp approaches stay covered across the shift. Capacity is sized so a full duty cycle can be met on a single overnight charge, with reserve state of charge held at end of shift as a design margin. Pack dimensions, mounting points and connector position are matched to the vehicle’s controller envelope and mechanical bay, so a service swap remains a workshop task. Swap-ready packs carry cell-level telemetry over the same CAN link the vehicle controller already uses. Payload capability is preserved because the pack is specified within the original gross vehicle weight allowance. Preventive maintenance intervals, workshop tooling and spare-part scope are set from the duty cycle during configuration.

The open question for a three-wheeler cargo fleet is whether the vehicle can complete a full shift with a full commercial payload on board. That is the duty cycle the pack has to be specified around.

Verification

How to verify before ordering

  • Evaluation packs run on the actual loaded route, comparing energy per trip before and after conversion
  • Capacity tolerance and cycle data from the sorting and test records
  • Mounting drawing and connector list checked against one converted vehicle before the batch is built
  • UN38.3 test summary report and transport documents
  • Quotation naming pack voltage, capacity, enclosure, connector and warranty terms
