A cold-weather EV truck is a different animal from a Gulf one, and Kazakhstan fleets learn that fast in a -25°C January. The TE9L electric tractor is a 6x4 prime mover with a 450 kWh CATL LFP pack and LvKong motors up to 510 kW, built for the long freight corridors between Almaty, Astana and the Russian border. At low temperature the pack holds less usable energy and the cabin heater draws from the same battery, so range planning must start from winter data, not summer brochures.
The good news is that LFP chemistry is more cold-tolerant than older lithium types, and the TE9L ships with a pre-heating system that warms the pack on grid power before the shift. With the right routine, a Kazakhstan fleet loses only 18 to 28 percent range in deep winter instead of the 40 percent a cold-start pack would suffer.
The table below shows representative TE9L range on a 60-ton gross combination weight at a steady 80 km/h, with and without pack pre-heat. The numbers come from corridor trials on the Astana route and are the basis for winter dispatch planning.
| Ambient | No pre-heat range | Pre-heat range | Loss vs 20C |
|---|---|---|---|
| 20°C | 340 km | 340 km | 0% |
| 0°C | 285 km | 312 km | 8% |
| -15°C | 232 km | 278 km | 18% |
| -25°C | 198 km | 252 km | 26% |
| -35°C | 170 km | 224 km | 34% |
The takeaway is direct: pre-heating recovers roughly 50 to 70 km of range at the cold end, which is the difference between one trip and a stranded tractor. Fleets size the winter round trip to the pre-heat column, not the brochure, and they build a charger stop into any corridor longer than 220 km.
The TE9L pre-heats the pack from grid power while the driver does the walk-around, lifting cell temperature from -25°C to about 10°C in 40 to 60 minutes. That warm start lets the pack accept full regen on the descent and deliver full motor power on the climb, which a cold pack cannot do safely.
Pre-heat energy is cheap because it comes from the night grid near 0.04 USD per kWh in Kazakhstan, and it is far cheaper than the diesel a competitor burns to idle a cab warm. The TE9L pays for its heater in the first winter alone.
Winter charging is slower because a cold pack accepts less current, so the 240 kW DC unit that fills in 90 minutes at 20°C may need 130 minutes at -25°C. The fix is to arrive with the pack already warm from regen and to charge inside a sheltered bay where ambient is higher than the open steppe. Fleets build a 30-minute buffer into the driver rest so the slower charge never breaks the schedule.
A 500 kWh stationary buffer at the depot lets the charger draw off-peak power and deliver it fast when the tractor arrives, which hides the grid's own winter strain. Where the corridor is long, a mid-point charger at a truck stop turns one impossible leg into two easy ones.
The cabin draws 4 to 7 kW for heat at -25°C, which comes from the pack. Drivers are trained to pre-warm on grid power, then hold a steady 18°C with seat and steering heat so the main pack load stays low. A warm driver is a safe driver on black ice, and the TE9L's quiet cab helps spot other traffic that a diesel engine would mask.
Tires are the other winter item. Cold air drops pressure, so the daily card adds a pressure check, and fleets fit tread rated for the corridor. None of this is unique to an EV truck, but it matters more when the same battery must also move the load.
| Cost line | Diesel tractor | TE9L EV truck |
|---|---|---|
| Energy per 1000 km | 420 USD | 95 USD |
| Winter pre-heat | idle fuel | 6 kWh grid |
| Maintenance per year | 30,000 USD | 13,000 USD |
| Cold start wear | High | Low |
| 3-year saving | - | ~230,000 USD |
Even with winter loss, the TE9L saves roughly 230,000 USD over three years per tractor because diesel idling for cab heat is expensive and the electric heater is not. For a Kazakhstan corridor fleet, the EV truck is a winter winner, not a summer-only toy.

Cold air drops tire pressure and black ice breaks traction, so the TE9L winter card adds a pressure check to every start and fits tread rated for the corridor. The electric drivetrain helps here because torque is smooth from zero, so the driver can roll onto ice without the wheelspin a diesel clutch would provoke. The heavy battery also lowers the center of gravity, which steadies the tractor on the graded shoulders of the Astana highway.
None of this is unique to an EV truck, but it matters more because the same pack must also move the load, so a traction incident that strands a diesel also strands the energy plan. The trained driver treats the corridor as a system, not just a road.
Buyers worry that cold shortens pack life, but the TE9L's pre-heat routine keeps the cells in a narrow band, so three-year state of health stays near 90 percent even in Almaty winters. The 8-year or 4500-cycle CATL LFP warranty transfers, and a warm-start history is a selling point at trade-in. Kazakh fleets that rotate tractors every three years recover more of the FOB price than diesel peers whose engines are already worn by cold starts.
| Factor | Diesel tractor | TE9L EV truck |
|---|---|---|
| Cold-start wear | High | Low |
| 3-year pack health | n/a | 88-91% |
| Residual value | 34% | 50% |
| Winter fuel cost | idle heavy | grid warm |
The stronger residual plus the lower winter energy bill means the TE9L often costs less to own over three years than the diesel it replaces, even before the maintenance gap. For a Kazakhstan corridor fleet, that is the number that ends the debate.
For Kazakhstan operators, the rule is simple: warm the pack, plan the winter range, and the EV truck will out-pull diesel on the same corridor while costing far less to run through the hardest months.
