Quick answer: Most electric truck fleets need a 120-360 kW DC fast charger; a 350 kWh pack reaches 10-80 percent in 45-75 minutes on 360 kW. Trucks with 500-600 kWh packs should plan for MCS megawatt charging up to 1 MW to refill in 35-45 minutes. Size the charger to the battery and the shift, not to the biggest number on the spec sheet.
Charger size is the question every fleet operator asks first, and the honest answer depends on two numbers: the battery pack in kWh and the time you have to charge it. A Dongfeng EV truck with a 210 kWh pack and a 200 km daily route needs far less than a 600 kWh mining unit running two shifts. Getting the kW right avoids both an underpowered bay that strands trucks and an oversized cabinet that wastes capital. The TE8P heavy electric tractor with its 600 kWh pack and 510 kW motor is the clear case for planning megawatt charging from day one.
For the typical 210-424 kWh trucks that make up most municipal, cargo and regional tractor fleets, a 120-360 kW DC fast charger is the sweet spot. At 360 kW, a 350 kWh pack moves from 10 percent to 80 percent in 45-75 minutes, which fits a driver break or an overnight depot window. Smaller 210-262 kWh units are happy on 120-150 kW, reaching the same window in 60-90 minutes. The key is matching the charger to the pack so the truck is ready when the route demands, not faster than the route needs and not slower than the shift allows.
A simple rule: divide the usable kWh you need to add by the hours you have, then add 20 percent for losses and taper. If a 350 kWh truck arrives at 10 percent and must leave at 80 percent in one hour, it needs about 245 kWh in 60 minutes, or roughly 250 kW; a 360 kW unit covers it with margin. The table below shows common pack sizes and the charger that fits a one-hour turnaround.
| Pack size | 10-80 percent energy | Charger for 1h | Time at 360 kW |
|---|---|---|---|
| 210 kWh | 147 kWh | 150-180 kW | 25-35 min |
| 350 kWh | 245 kWh | 300-360 kW | 45-60 min |
| 424 kWh | 297 kWh | 360 kW | 55-70 min |
| 600 kWh | 420 kWh | 1 MW (MCS) | 35-45 min |
This matching step prevents the two common errors: buying a 60 kW charger that can never serve a 350 kWh truck, or buying 1 MW where 360 kW would do. Real charging tapers above 80 percent, so design around the 10-80 percent window and let the last 20 percent happen slowly overnight or during idle. This keeps the charger kW you need lower and protects pack life across the 4,500-cycle warranty.
MCS (Megawatt Charging System), rated up to 1,250 A and 1 MW, is for the 500-600 kWh class: heavy dump trucks, mining units and long-haul tractors such as the TE8P. At 1 MW a 600 kWh pack refills 10-80 percent in 35-45 minutes, comparable to a diesel stop. If your fleet includes any 500-600 kWh units, reserve at least one MCS-capable bay and a 3.0-4.0 MVA grid feed, because a 360 kW charger would need 90-120 minutes for the same pack, which is too slow for two-shift mining and wastes the expensive battery you already bought.
The charger connector must match the truck inlet: CCS2 for Europe, GCC and most of Latin America, GB/T for China-aligned fleets, and MCS for 500-600 kWh packs. A 350 kWh truck on CCS2 charges at 120-360 kW; the same pack on GB/T needs a compatible charger or a $1,200-4,500 adapter below 250 kW. Specify the inlet on the purchase order and the depot charger to match, because a mismatch strands the truck regardless of how many kW the cabinet delivers. Most Dongfeng EV truck exports to emerging markets arrive with selectable inlets, so confirm the exact protocol (ISO 15118 or GB/T 27930) before the grid is commissioned.
For a mixed fleet of 210-424 kWh trucks, yes, with smart phasing. A 20-truck depot does not need 20 chargers; four to six 360 kW stalls active in rotation cover the fleet if charging is spread across shifts. Plan a 1.5-2.5 MVA grid connection, use load balancing so stalls share the feed, and add battery storage to shave peak demand. Load balancing matters as much as raw power: a smart controller can serve six 360 kW stalls by shifting current to whichever truck is in its fastest band, preventing utility trips that would stop the whole fleet. Only if several 600 kWh MCS trucks are present do you need the higher 3.0-4.0 MVA feed and a dedicated megawatt bay.
A 360 kW DC charger costs about $35,000-70,000 installed in 2026, including the mount, the cable and basic switchgear. A 1 MW MCS cabinet runs $150,000-300,000 once liquid cooling and the heavier feed are included. Budget the grid connection separately at 6-18 months lead time, and remember the cable itself ($3,000-8,000 for a liquid-cooled 360 kW unit). The Bangladesh electric truck market shows the typical emerging pattern: start with 120-360 kW CCS2 or GB/T chargers sized to the first 210-424 kWh trucks, then reserve MCS capacity as 600 kWh units arrive and the duty cycle grows.
No. Charging is a scheduled event, not a parking space, so a depot rarely needs a stall per truck. A 20-truck fleet with four to six 360 kW chargers and a 1.5-2.5 MVA feed covers the daily cycle if charging is spread across shifts and breaks, because most trucks are on the road while a few top up. Buying one charger per truck would double the $35,000-70,000-per-stall capital for capacity that sits idle most of the day. Right-size the stall count to the peak simultaneous demand, not the fleet headcount, and reserve the MCS bay only for the 500-600 kWh units that truly need it.
Oversizing is reasonable only at the grid and the bay, not necessarily the cabinet. Reserve a 3.0-4.0 MVA feed and pre-lay conduit for MCS if you expect 500-600 kWh trucks, because that is cheap to do during the build and expensive later. But buying a 1 MW cabinet for a fleet of 210-424 kWh trucks wastes $100,000-230,000, since those packs never accept more than 360 kW. The balanced approach is a 360 kW cabinet today plus a bay and feed ready for MCS, so you add the megawatt unit only when the first 600 kWh truck arrives.
This staged plan also smooths capital. You spend $35,000-70,000 per 360 kW stall now and defer the $150,000-300,000 MCS cabinet until the duty cycle proves it. Combined with load balancing on the 1.5-2.5 MVA feed, a 20-truck depot stays ready for growth without paying for power it cannot yet use, which is the most cost-effective way to future-proof an EV truck charging yard while keeping the first trucks on the road tomorrow.
Size the charger to the battery and the shift and you get trucks that are always ready, with no wasted capital. Most fleets land at 120-360 kW today and keep one MCS bay ready for the biggest packs tomorrow, which is the cheapest way to stay flexible as the fleet and the routes evolve over the next decade.
A 350 kWh electric truck needs a 120-360 kW DC charger; at 360 kW it reaches 10-80 percent in 45-75 minutes and a 360 kW unit costs $35,000-70,000 installed in 2026.
Yes, a 600 kWh electric truck can use a 360 kW charger, but it needs 90-120 minutes for a 10-80 percent charge; for a 35-45 minute refill use a 1 MW MCS unit.
A 20-truck depot needs 4-10 DC chargers at 120-360 kW plus a 1.5-2.5 MVA grid connection; add one MCS bay if any 500-600 kWh trucks are in the fleet.
A 360 kW DC charger costs $35,000-70,000 installed in 2026, while a 1 MW MCS cabinet runs $150,000-300,000 including liquid cooling and switchgear.
Size the charger to the route and shift length; a 200-350 km daily route with a 262-424 kWh pack needs 120-360 kW, while 500-600 kWh mining trucks need MCS megawatt charging.
