Charging standards, battery chemistry, driver-assistance systems and regulatory frameworks — explained plainly.
Charging
CCS Combined Charging System
▼
The dominant DC fast-charging standard in Europe & North America.
CCS merges AC and DC charging pins into one connector. CCS1 is used in North America; CCS2 in Europe. Most heavy trucks today charge via CCS, at up to ~350 kW. Windrose supports both variants, enabling operation across both continents without adapters.
Charging
MCS Megawatt Charging System
▼
Next-generation charging designed specifically for heavy trucks — up to 3.75 MW.
A new standard developed for commercial freight. The connector is physically larger than CCS and uses a dedicated high-power protocol. At 1–3.75 MW, a Windrose truck can reach 80% charge in roughly 30 minutes — comparable to a diesel fuel stop. MCS depots are being deployed now by Milence, Greenlane, Terawatt and others.
Charging
Plug&Charge ISO 15118
▼
Plug in and charging starts — no card, app or PIN required.
ISO 15118 is the protocol that allows a vehicle and charger to identify each other and handle billing automatically at the moment of connection. The Windrose–Hubject partnership enables Plug&Charge at over 1 million charge points across 70+ countries. For fleet operators this means zero driver friction and automated cost reporting.
Battery
LFP Lithium Iron Phosphate
▼
The battery chemistry Windrose uses — safer, longer-lived, and charge-cycle tolerant.
LFP substitutes iron and phosphate for the nickel, manganese and cobalt used in most passenger-car batteries. The result: no thermal runaway risk, a lifespan of 3,000–5,000 full cycles (versus ~1,000 for NMC), and the ability to charge to 100% daily without degradation. For a truck that charges every night, this is the right chemistry — even if energy density per kilogram is slightly lower than NMC.
Battery
SOC State of Charge
▼
The battery's current charge level, expressed as a percentage.
SOC is the electric equivalent of the fuel gauge — 0% is empty, 100% is full. Windrose's battery management system monitors SOC in real time and warns the driver when it drops below 20%. Fleet operators typically plan routes to keep SOC above 15% at destination, with MCS charging scheduled en route for long hauls.
Drivetrain
ePTO Electric Power Take-Off
▼
Powers auxiliary equipment — refrigeration, cranes, hydraulics — directly from the battery.
On a conventional diesel truck, a PTO draws mechanical power from the engine to run attachments. ePTO does the same electrically. For refrigerated transport, construction site work or tanker trucks, ePTO eliminates the need for a separate diesel generator. Windrose offers ePTO / MPTO (Mechanical PTO) as an option from Generation 3 onwards.
Drivetrain
B-double
▼
A two-trailer road train — the configuration behind Windrose's maximum payload figure.
A B-double couples two semi-trailers in series behind a single prime mover. Permitted in Australia, New Zealand and parts of Europe, it allows gross combination masses above the standard 44-tonne European limit. When Windrose states a maximum payload, it refers to this configuration — which places the highest possible demand on range and powertrain, making it the toughest benchmark for long-haul capability.
Driver Assistance
ADAS L2+ / L4
▼
Levels of driving automation — from highway assistance to full self-driving within a defined zone.
SAE defines six automation levels. L2 controls both steering and speed simultaneously but requires the driver to remain alert. L2+ extends highway assistance with lane-keeping, adaptive cruise and emergency braking on motorways. L4 is full autonomy within a defined operational domain (e.g. a specific port or warehouse zone) — no human intervention required within that area. Windrose trucks ship with L2+ ADAS standard and roadmap to L4.
Driver Assistance
AEB Autonomous Emergency Braking
▼
Automatically applies the brakes if a collision is imminent and the driver hasn't responded.
AEB uses millimetre-wave radar and a forward camera to track obstacles ahead. If it predicts a collision and the driver hasn't braked, it intervenes autonomously. At 80 km/h, even a 1-second early braking event reduces crash energy by ~30%. AEB is standard on all Windrose trucks and is mandatory under European regulation for new heavy vehicles.
Driver Assistance
AVM Around-View Monitor
▼
Composites multiple cameras into a 270° bird's-eye view for docking and reversing.
AVM stitches together feeds from cameras mounted around the vehicle into a single overhead perspective displayed on the dashboard. For a truck reversing onto a loading dock or navigating a tight warehouse, it removes the main blind-spot risk. Windrose's AVM provides 270° coverage, the driver monitors it as they would a reversing camera.
Driver Assistance
ACC Adaptive Cruise Control
▼
Maintains a set speed and safe following distance automatically in highway traffic.
ACC uses radar to track the vehicle ahead and automatically adjusts speed to maintain a preset following gap. On long motorway hauls this significantly reduces driver fatigue. Windrose's ACC integrates with the regenerative braking system — when slowing for a vehicle ahead, energy is recovered rather than wasted as heat.
Driver Assistance
AR-HUD Augmented Reality Head-Up Display
▼
Projects navigation, speed and lane guidance onto the windscreen — eyes stay on the road.
A HUD projects information onto the lower windscreen so the driver reads it without looking down. The AR variant overlays graphics aligned to the real road ahead — navigation arrows appear to float above the actual lane, lane-departure warnings highlight the road marking being crossed. Windrose's AR-HUD is available from Generation 3 as an optional feature.
Regulatory
FMVSS US Federal Safety Standards
▼
The federal rulebook every vehicle sold in the US must pass — the equivalent of EU type approval.
Federal Motor Vehicle Safety Standards (49 CFR Part 571) set minimum performance requirements for brakes, lighting, occupant protection, tyres and dozens of other systems. Compliance is self-certified by the manufacturer. Windrose holds full FMVSS compliance, enabling registration and operation in all 50 US states.
Regulatory
CARB ZEV · ACT · HVIP
▼
California's zero-emission truck mandates and incentive programme — the most influential in the world.
The California Air Resources Board sets the toughest clean-vehicle rules globally, and 17 other US states follow them. ZEV (Zero Emission Vehicle) mandates require manufacturers to sell increasing percentages of zero-emission trucks. ACT (Advanced Clean Trucks) sets the specific sales percentages by year. HVIP (Hybrid and Zero-Emission Truck Incentive) provides rebates of up to $120,000 per truck to buyers, directly closing the price gap with diesel. Windrose is CARB ZEV/ACT qualified and HVIP eligible.
Regulatory
MIIT / GB/T China Type Approval
▼
China's vehicle approval authority and national technical standards.
The Ministry of Industry and Information Technology issues type approval for all vehicles sold in China. GB/T (Guojia Biaozhun / Tuijian) are the national recommended standards — covering battery safety, charging interfaces, energy consumption, telematics and dimensions. Windrose holds MIIT type approval and GB/T compliance for its China-market vehicles.
Regulatory
ECAS Electronic Air Suspension
▼
Electronically adjustable air suspension — adapts ride height for loading docks and road conditions.
ECAS allows the driver to raise or lower the chassis from the cab. At a loading dock, lowering the rear to dock height eliminates the ramp gap and reduces loading time. On motorways, a lower ride height reduces aerodynamic drag — directly improving range. The system also maintains level ride height automatically as load shifts during the journey.
Safety
TPMS Tyre Pressure Monitoring
▼
Real-time pressure and temperature monitoring for every tyre.
Under-inflated tyres are the single largest cause of tyre failure on heavy trucks, and each 10% under-inflation adds ~1% fuel/energy consumption. Windrose's TPMS monitors all tyres continuously and alerts the driver to any deviation. For fleet operators this reduces tyre replacement costs and improves range predictability on long routes.
