Port drayage is the easiest trucking job to electrify and the hardest to justify without a real number. This article builds a five-year total cost of ownership (TCO) model for the Dongfeng TE46 282kWh terminal tractor against a comparable diesel prime mover on African port lanes, so fleet buyers can see where the electric truck pays back and how fast.
The TE46 is a 4x2 terminal tractor with a 282kWh CATL LFP pack, GCW 42 t and a 20–80% charge time of 60–90 minutes. It is purpose-built for short, repetitive port and depot shuttles where a truck runs 18–22 hours a day at low speed and high cycle count — exactly the profile where diesel idling burns the most fuel for the least work.
We model two tractors over five years at 60,000 km per year (300,000 km total) on a Dar es Salaam container lane:
Over 300,000 km the diesel burns 96,000 L at $1.15 = $110,400. The TE46 draws 480,000 kWh at $0.14 = $67,200. Electricity saves $43,200 over five years, roughly 39% lower energy cost. With solar or off-peak tariffs common at African ports, that gap widens toward 50%.
| Cost item (5 yr / 300k km) | Diesel | TE46 EV |
|---|---|---|
| Fuel / energy | $110,400 | $67,200 |
| Maintenance | $33,000 | $10,500 |
| Acquisition | $95,000 | $88,000 |
| Charger amortised | $0 | $9,000 |
| Total | $238,400 | $174,700 |
The TE46 has roughly one moving drivetrain part where a diesel has hundreds. No oil changes, no DPF, no turbo, no clutch wear. Maintenance lands at $0.035/km versus $0.11/km for diesel — a $22,500 saving over the model. Uptime also rises: fewer breakdowns mean more container moves per shift, and the 8-year/4,500-cycle battery warranty covers the pack for the whole analysis.
The TE46 saves about $63,700 over five years versus diesel, recovering its small price premium and charger in under three years. CO2 drops by roughly 240 tonnes per tractor over the period. For Tanzanian port operators, that is both a balance-sheet and a tender win, since many terminals now score low-emission drayage. See the TE46 electric tractor page for specs, and our Tanzania electric truck market guide for port import detail.
Port drayage is the clearest EV truck business case in Africa: lower energy, lower maintenance and faster payback than almost any other duty cycle.

Charging an electric truck is a depot discipline, not a public-network gamble. A 262 kWh pack working a 200 km day typically returns with 25 to 35 percent in reserve, so overnight demand is about 157 kWh per truck. On a 120 kW DC charger the pack climbs from 20 to 80 percent in roughly 79 minutes; on 240 kW that falls to about 39 minutes, which lets two trucks share one charger on staggered shifts.
Size the site transformer for your busiest shift plus 30 percent headroom, keep cable runs under 30 metres to limit voltage drop, and meter each charger separately so energy cost per truck stays visible. In Tanzania, grid connection lead times of three to nine months are common, so apply for the connection the day you sign the truck order, not the day the ship arrives. Shaanxi Fenghan Trading includes a charger layout drawing and load calculation with every EV truck quotation, so your electrician can price the civil works before the truck lands.
A comparable diesel terminal tractor burns about 0.38 litres per kilometre in mixed duty; at $0.95 per litre that is roughly $0.36 per km. The electric equivalent consumes about 1.15 kWh per km fully loaded; at an industrial tariff of $0.10 per kWh the cost is near $0.12 per km, and overnight or solar-coupled charging can push it below $0.08. Over 70,000 km a year the saving is about $17,000 per truck, before any carbon or low-emission-zone benefit.
The gap widens in stop-start duty, where regenerative braking returns 15 to 25 percent of traction energy instead of burning it as brake dust. In Tanzania, where diesel quality and price both fluctuate, locking in an electricity tariff also removes a major budgeting variable from the fleet P&L.
The TE46 has roughly one moving drivetrain part where a diesel has hundreds: no engine oil, no DPF, no turbocharger, no clutch, no multi-gear transmission service. Scheduled maintenance lands near $0.035 per km against $0.11 per km for a diesel equivalent, a saving of more than $5,000 a year at typical utilisation. Brake pads last two to three times longer because the motor does most of the deceleration.
Uptime matters more than parts cost. Fleet data from Chinese operators running the same e-axle platform shows 96 to 98 percent availability once drivers are trained, versus 92 to 94 percent for diesel trucks of the same age. Keep a small stock of filters, coolant, brake pads and 12V batteries on site; Shaanxi Fenghan Trading quotes a two-year consumables kit with every truck so the first service interval never waits on freight.
Every TE46 pack carries an 8-year or 4,500-cycle warranty with a 70 percent state-of-health guarantee. At one charge per working day, 4,500 cycles is more than twelve years of service, so the pack is warranted for the entire first ownership period of most fleets. LFP chemistry also tolerates full charges, which removes the 80-percent daily ceiling that NMC operators must manage.
Residual value is the question every CFO asks. Three data points help: LFP packs retain 70 to 80 percent capacity at end of warranty, which supports a second life in stationary storage; diesel residuals in export markets have already started sliding where zero-emission zones are announced; and a truck with a transferable battery warranty simply sells faster. Prudent fleets model 35 to 45 percent residual at year five for an EV truck versus 40 to 50 percent for diesel, then recover the difference through energy savings inside year three.
