Global EV truck sales jumped nearly 80% in 2024, with China accounting for more than 80% of all units. The Megawatt Charging System (MCS) delivered its first public sessions in Europe (August 2025) and North America (March 2026), setting a new ceiling for heavy-duty charging speed. Depot charging dominates today, but corridor infrastructure is scaling quickly through DOE funding and private investment. Regulations in the EU, California, and the US at the federal level are compressing the decision window for fleet operators. Fleets that plan charging infrastructure now—sized correctly for CCS today and MCS-compatible tomorrow—will have an operational edge as the market tightens.
Where the Market Stands in 2026
The numbers make a clear case. Global electric truck sales grew by nearly 80% in 2024, reaching close to 2% of total truck sales worldwide—a modest share that nonetheless represents an inflection in a segment that barely registered a few years ago. (Source: IEA — Global EV Outlook 2025)
China drives the majority of that volume. More than 80% of all electric trucks sold globally in 2024 were sold in China—roughly 75,000 units—fueled by tightened emission standards, trade-in incentives, and falling battery costs. The pace accelerated further into 2025: China registered 231,100 new energy heavy-duty trucks for the full year, a 182% increase over 2024. By December 2025, electrified trucks captured 54% of China’s monthly heavy-duty market—the first month electric outsold diesel in that category.
Outside China, growth in 2025 was slower. The US registered only a few hundred zero-emission medium- and heavy-duty trucks per quarter, constrained by limited corridor charging infrastructure, high vehicle costs, and policy uncertainty following changes to federal mandates. Other markets—Europe, India, and parts of Southeast Asia—showed volume growth from a small base but remain early-stage by comparison.
The IEA projects that one in eight trucks sold globally by 2030 will be electric, implying a continued steep adoption curve that depends on charging infrastructure keeping pace with the vehicles.
What Is the Megawatt Charging System (MCS) and Why Does It Matter?
Short answer: MCS is a charging standard for heavy-duty vehicles that delivers more than 1 megawatt of power—enough to take a Class 8 truck battery from 20% to 80% in under 30 minutes, aligning with mandatory driver rest periods under hours-of-service rules.
For context, current DC fast chargers top out at roughly 350 kW under the Combined Charging System (CCS). A Class 8 truck with a 400–600 kWh battery pack takes two to four hours to charge at that rate—acceptable overnight at a depot, but impractical for long-haul operations where every hour matters.
MCS changes that calculus. The SAE J3271 standard was published in March 2025, and the International Electrotechnical Commission followed with IEC TS 63379 in February 2026, giving the standard a firm technical and international foundation.
Real-world sessions have now taken place. In August 2025, the world’s first public MCS charging session occurred at a truck charging site in Norrköping, Sweden, where a Kempower Mega Satellite charged a Scania truck.
Seven months later, in March 2026, the first MCS session in North America was completed at EV Realty’s San Bernardino hub in California, where a Kempower 1.2 MW system charged a Windrose electric truck at up to 1,500 amps through liquid-cooled cables.
Table 1. CCS vs. MCS: Key Differences for Heavy-Duty Truck Operators
| Feature | CCS (DC Fast Charge) | MCS (Megawatt Charging System) |
|---|---|---|
| Max power output | Up to 350 kW | Up to 1.5 MW (3.75 MW max in spec) |
| Connector type | CCS1 (North America) / CCS2 (Europe/global) | Dedicated MCS connector (ISO/IEC standard) |
| Typical charge time for Class 8 | 2–4 hours (400–600 kWh pack) | Under 30 minutes (20%–80%) |
| Primary use case | Depot overnight; regional haul | Long-haul corridors; high-utilization fleets |
| Standards body | CharIN / SAE / IEC | CharIN / SAE J3271 / IEC TS 63379 |
| Current deployment status | Widely deployed globally | First public sessions: 2025 (EU), 2026 (North America) |
| OEM support timeline | Production vehicles available now | OEMs (Daimler, Traton, Scania) announcing MCS-capable trucks for 2026–2027 |

The transition to MCS will be gradual. Kempower and others recommend a dual-infrastructure strategy: install CCS capacity today for current vehicles, while engineering the site for MCS compatibility. This approach avoids stranded investment while serving the growing fleet of MCS-capable trucks expected to arrive in volume from 2027 onward.
Depot Charging vs. Corridor Charging — Which Model Wins?
Short answer: Depot charging wins for most fleets today. Corridor charging is essential for long-haul and is where the next wave of investment is going.
NACFE’s Run on Less – Electric DEPOT demonstration, tracking 22 battery electric trucks across 10 fleet depots in the US and Canada, found that depot-level charging can handle a wide range of duty cycles—from terminal tractors and delivery vans to regional Class 8 day cabs. The 10 depots operated 294 BEVs using 139 chargers and consumed 1,044 MWh over three weeks while trucks covered 446,831 miles.
However, NACFE also found a persistent problem: it took 9 to 36 months to energize the electrical infrastructure at those same depots. Utility interconnection delays and permitting timelines remain the biggest operational friction in fleet electrification.
On the corridor side, the US Department of Energy committed $68 million in January 2025 through the SuperTruck Charge initiative to fund high-power public charging sites near ports, distribution hubs, and freight corridors. Projects include a 10+ MW charging station in Barstow, California, along the I-15 corridor, and a 9 MW site on the I-10 corridor with MCS-compatible chargers, solar canopies, and 3 MW of battery storage.
Table 2. Depot vs. Corridor Charging: Practical Comparison for Fleet Managers
| Factor | Depot Charging | Corridor / Public Fast Charging |
|---|---|---|
| Typical power level | 10–350 kW (AC Level 2 to DC fast) | 150 kW–1.5 MW (DC fast to MCS) |
| Charging session length | 4–12 hours (overnight) | 30 minutes to 2 hours |
| Infrastructure lead time | 9–36 months (utility interconnect) | Variable; highway sites often 12–24 months |
| Best duty cycle fit | Regional haul, delivery, terminal ops | Long-haul freight, multi-shift operations |
| Cost per port installed | $2K–$150K (Level 2 to DC fast) | $150K–$500K+ (high-power DC / MCS) |
| Grid integration complexity | Low to moderate | High; battery storage often required |
| Current maturity | Commercial scale, proven | Early commercial; scaling 2025–2028 |

The practical guidance for most fleet operators: start with depot charging for the vehicles and routes you can electrify today, and plan the site for future power capacity. Running conduit for future ports and designing the electrical service with headroom costs less now than retrofitting later.
Regulations Pushing the Timeline Forward
Policy is doing the work that market economics alone cannot yet complete—at least in North America and Europe. The timelines are concrete enough that fleet procurement decisions made today will be directly affected.
- European Union.
The revised EU CO2 standards for heavy-duty vehicles require a 45% reduction in CO2 relative to 2019 levels by 2030, rising to 65% by 2035 and 90% by 2040. These targets are among the most ambitious greenhouse gas standards for commercial vehicles anywhere in the world.
The EU’s Alternative Fuels Infrastructure Regulation (AFIR) separately mandates charging availability on major European transport routes.
- California.
CARB’s Advanced Clean Trucks (ACT) regulation requires manufacturers to sell an increasing percentage of zero-emission trucks into California. The 2026 requirement for Class 2b–8 trucks starts at 10% (Class 2b–3) and reaches 15–20% in 2027 across vehicle classes, escalating toward 100% by 2035–2036. Fourteen other US states have adopted or are adopting ACT. The Advanced Clean Fleets (ACF) regulation was partially repealed in October 2025 for private fleets, but the ACT manufacturer mandate remains fully in force.3.
EPA’s Phase 3 Greenhouse Gas standards, finalized in March 2024 and under reconsideration as of early 2026, set CO2 reduction targets of up to 60% for vocational trucks and up to 40% for tractor trucks by model year 2032, with phase-in beginning in 2027. Even under regulatory uncertainty, manufacturers are investing in ZEV product lines because the EU and California markets require it.
Table 3. Regulatory Mandates Shaping Electric Truck Procurement Through 2035
| Regulation | Region | Key Target | Timeline | Relevance to Fleet Operators |
|---|---|---|---|---|
| EU HDV CO2 Standards (Revised) | European Union | 45% CO2 reduction vs. 2019 | By 2030 | Manufacturers must sell ZEVs; fleet replacement cycles affected |
| EU CO2 Standards — Intermediate | European Union | 65% CO2 reduction vs. 2019 | By 2035 | Accelerates electrification of long-haul segment |
| CARB Advanced Clean Trucks (ACT) | California + 14 states | 10% ZEV sales (Class 2b–3) in 2026; rising to 100% by 2035 | 2026–2035 | Limits ICE truck availability in ACT states; affects used market |
| EPA Phase 3 GHG Standards | USA (Federal) | Up to 60% CO2 cut (vocational) / 40% (tractors) vs. Phase 2 | MY 2027–2032 | Technology-neutral but requires ZEV mix in manufacturer fleet |
| EU AFIR Regulation | European Union | Charging coverage on major transport routes | 2025 onwards | Mandates public truck charging every 60 km on TEN-T core network |

How Charging Infrastructure Needs to Scale
The supply-demand math is stark. The IEA estimates that public charging infrastructure globally must grow ninefold by 2030 to support projected EV adoption under current policy scenarios. (Virta — IEA Global EV Outlook 2025 summary) The heavy-duty segment is proportionally underserved.
Progress is visible in sub-segments. Ultra-fast chargers (above 150 kW) grew 50% globally in 2024 to reach 71,000 units, now making up nearly 10% of all public fast chargers. China had approximately 1,350 truck-specific charging stations with more than 5,500 charging points above 320 kW by October 2024—a benchmark that Europe and North America are working to replicate.
Large-site grid management has become a practical constraint. A single MCS station drawing 1–3 MW can exceed the grid capacity of many existing commercial locations. Battery storage systems are increasingly standard on new high-power charging sites, allowing operators to draw from the grid at a steadier rate while delivering peak power during charging events. The DOE’s SuperTruck Charge sites all combine charging with on-site battery storage and solar for this reason.
What This Means for Fleet Operators Choosing Charging Equipment
The practical question for any fleet buying or planning a charging system in 2026 is: what connector standard, power level, and site architecture will remain useful in five years?
On standards:
CCS2 (global markets) and CCS1/NACS (North America) are the working standards for current production trucks. Every electric truck on the road today charges via CCS. NACS is growing in North American light-duty and is designed to support megawatt-level charging in future iterations. Fleets operating in multiple regions need equipment that handles both connector families.
On power levels:
For depot applications handling regional haul or delivery duty cycles, DC fast chargers in the 30–150 kW range typically match overnight dwell time. Higher-utilization depots or those running two shifts need 150–400 kW units. Corridor and public-access sites require 350 kW and above, with MCS compatibility becoming important as long-haul vehicle volumes grow after 2027.
On site design:
Electrical service sizing, conduit layout, and switchgear selection made today determine how easily a site can be upgraded. Building for 20% more capacity than the first phase requires is a standard best practice. Integrating battery storage from the outset is worth evaluating at any site where peak demand charges are significant.
JointCharging manufactures DC fast chargers from 30 kW to 400 kW supporting CCS2 (global), CCS1, and NACS (North America), along with energy storage systems designed for commercial EV charging applications. [NEEDS CONFIRMATION on specific heavy-truck-grade models and fleet depot configurations] Fleet operators can reach JointCharging at [email protected] to discuss site-specific requirements.
For global markets, JointCharging’s DC fast chargers (CCS2, 30–400 kW) and energy storage systems with EV charging address the growing need for high-power depot solutions. For North American operators, the company’s CCS1/NACS DC fast charger lineup is worth evaluating as part of fleet transition planning.
Conclusion
Electric truck charging is no longer a hypothetical infrastructure problem—it is an active engineering and procurement challenge for fleets across every region. Sales data, regulatory deadlines, and the arrival of MCS technology all point in the same direction: the window for “wait and see” is closing.
The decisions that will matter most over the next three years are not vehicle-level choices. They are infrastructure choices: which connector standards to support, what power levels to install, how to integrate storage with the grid, and whether site design leaves room to scale. Fleets that treat charging infrastructure as a strategic asset rather than a utility cost will be better positioned as the market conditions tighten and more electric models reach production scale.
The technology is ready for depot-based operations now. Long-haul corridor charging is arriving. Regulations in the EU, California, and the US federal system are removing optionality. Fleets and operators that plan for this now—not reactively—will carry the operational and cost advantage forward.
