Quick answer: A heavy electric truck charges from 20% to 80% in 45-70 minutes on a DC fast charger (240-360 kW), or fully overnight in 6-10 hours on AC depot charging. Battery-swap variants exchange a full pack in 5-6 minutes. Charging time depends on battery size (106-600 kWh in commercial trucks), charger power, and the pack’s temperature — not on marketing claims.
Three variables set the clock, and buyers should understand all three before comparing numbers. Battery size: a 106 kWh delivery-truck pack and a 600 kWh heavy-tractor pack are different jobs — the industry quotes 20-80% times precisely because that window is where chargers run at full power. Charger power: a 120 kW unit delivers energy at half the rate of a 240 kW unit, and liquid-cooled 360-500 kW units halve it again on large packs. The charging curve: every lithium pack charges fastest at low state of charge and tapers above ~80%, which is why route planning targets the 20-80% window and why “0-100%” figures are always misleading for operational planning.
| Truck Class (battery) | DC 20-80% Time | Overnight AC 10-100% | Range Restored (DC session) |
|---|---|---|---|
| Light delivery, 106-130 kWh | 30-40 min at 90-120 kW | 5-7 h at 22 kW | 110-140 km |
| Medium box/cargo, 140-180 kWh | ~40 min at 120 kW | 7-9 h at 22-40 kW | 120-150 km |
| Heavy rigid / port tractor, 282-350 kWh | 45-55 min at 240 kW | overnight via DC or 2x40 kW AC | 130-170 km loaded |
| Heavy tractor / dump, 400-600 kWh | 60-70 min at 360 kW dual-gun | overnight DC managed | 200-300 km loaded |
| Swap-variant (any large pack) | 5-6 min exchange | packs charge at station | 100% in 6 min |
Notice what the table says about operations: no class requires more than about an hour of fast charging to restore a working shift’s energy, and every class can be fully charged overnight. The “charging takes too long” objection dissolves when the truck’s own duty cycle provides the windows — parked nights, dock time, driver breaks, and shift changes. Our TE46 port tractor, for example, restores a 8-10 hour shift’s energy in a 45-minute lunch-window charge; fleets running Gulf drayage can see the operating context on our Saudi Arabia market page.
Yes — and it is the most under-discussed factor in the specification conversation. Lithium cells accept charge slowly when cold: a pack at -10°C may charge at a third of its rated speed until the thermal system warms it. The engineering answer is pack pre-heating: liquid-heated packs (standard on our trucks) warm during plugged-in standby, so a truck departing a depot arrives at the charger warm, and winter DC sessions run 65-75 minutes instead of 45-55 in the worst cold. Heat matters less: liquid cooling holds the pack in its optimal band through 45°C+ ambient, adding minutes, not fractions. The specification line to demand from any supplier is liquid thermal management — air-cooled packs lose this battle in both climates.
The decision tree is simpler than the industry makes it. Single-shift fleets (parked 12+ hours nightly): overnight AC or managed DC covers everything — fast charging is a convenience, not a need. Two-shift fleets: one 45-70 minute DC session per day, slotted into the shift change — this is the volume case for depot DC hardware. True 24/7 operations (ports, mining, round-the-clock construction): battery swap at 5-6 minutes, or opportunity charging at every queue and break — the TZ3V heavy dump truck’s swap-capable architecture serves precisely this duty. Long-haul: en-route fast charging matched to mandated driver breaks, which is why corridor trucks specify 360-500 kW capability. The fleets that get this right buy the minimum fast-charging hardware their shift pattern actually requires — and spend the savings on trucks.
A 600 kWh pack charges 20-80% in 60-70 minutes on a 360 kW dual-gun DC charger, restoring 200-300 km of loaded range. Battery-swap variants exchange the full pack in 5-6 minutes at a swap station.
Yes — most classes charge 20-80% in 30-70 minutes on DC fast charging: light delivery trucks (106-130 kWh) in 30-40 minutes at 90-120 kW, heavy trucks (282-600 kWh) in 45-70 minutes at 240-360 kW.
A 140 kWh delivery truck charges 10-100% in 7-9 hours on a 22 kW AC post; larger packs charge overnight on managed DC. Every truck class reaches 100% during a standard 10-12 hour depot night.
Occasional fast charging causes no measurable harm; CATL LFP packs carry an 8-year / 4,500-cycle warranty covering normal DC use. Fleets that fast-charge every session daily should expect slightly faster capacity fade — the telematics SOH report tracks it.
Yes — an automated swap station exchanges a 350-600 kWh pack in 5-6 minutes, faster than a diesel refuel. One station serves 10-15 trucks on 24/7 duty, making swap the standard answer for ports and mines.

Buyers comparing charging claims across suppliers should apply three tests, because the marketing conventions hide more than they reveal. Test one — window: any figure quoted without a state-of-charge window is meaningless; “charges in one hour” might mean 20-80% (the useful operational window) or 10-60% (a much smaller energy transfer). Test two — power versus delivery: a truck “capable of 350 kW” only charges at that rate where 350 kW chargers exist and the pack is warm and in the fast-charge window; the fleet’s real charging time is set by the hardware it will actually use. Test three — the curve: ask for the charging curve (power versus state of charge), not the headline number; two trucks with identical “45-minute” claims can differ by 20% in energy delivered if one holds peak power deeper into the session. Liquid-cooled LFP packs with modern charge maps hold their rate well — which is precisely the specification question the curve answers.
The operational conclusion follows directly: plan the fleet’s energy schedule on delivered energy per session, not on time per session. A 45-minute window that adds 130 km of loaded range is operationally excellent; the same window adding 60 km changes the shift plan. Our telematics platform reports exactly this — energy per session, per truck, per charger — and fleets quickly learn to schedule by the numbers rather than the clock. Charging time, in the end, is not the constraint newcomers fear: it is a plannable, measurable input to the dispatch day, sitting in windows the operation already owns. The trucks that charge “slowly” in the brochure and fully every night beat the trucks that charge “fast” against hardware that does not exist — and the fleet that understands that distinction has understood electric trucking.
