MITO EV Auto L5 cheat sheet

Level 5 EV automation: the system performs the entire dynamic driving task within its operational design domain (ODD); no human fallback is expected, so the ODD boundary is a safety-critical design element.

Energy per distance: E = (F_roll + F_aero + F_grad + F_accel) / η_drivetrain, with F_roll = m·g·C_rr, F_aero = 0.5·ρ·C_d·A·v², F_grad = m·g·sin θ.

Regenerative braking recovers only the tractive-braking portion; friction brakes must still supply the difference, and blending must be transparent to the driver and to stability control.

Battery state of charge (SoC) and state of health (SoH) are distinct: SoC is remaining charge fraction, SoH is capacity/power fade relative to beginning of life.

Thermal runaway in Li-ion cells is triggered by overcharge, internal short, or overheating; propagation mitigation (cell spacing, barriers, venting) is a pack-level design requirement.

ISO 26262 ASIL (A-D) is assigned from severity, exposure, and controllability; ASIL D is the highest integrity requirement for safety goals.

Sensor fusion for L5 typically combines camera, radar, and lidar; each modality has complementary failure modes (glare, rain attenuation, retroreflector saturation).

Charging power: P = V × I. DC fast charging follows a CC-CV profile; the charge curve tapers above roughly 80% SoC to protect cell life.

Heavy-duty EV energy use scales with gross combination mass and aerodynamic drag; a 40 t tractor-trailer at highway speed is dominated by aero and rolling resistance, not acceleration.

Payload penalty: battery mass directly reduces freight capacity, so total cost of ownership must be computed per tonne-km, not per vehicle-km.

Drivers' hours rules cap daily driving and require breaks; megawatt charging dwell must be scheduled inside mandatory rest periods to avoid productivity loss.

Depot charging load: simultaneous chargers create a site demand spike; load management or staggered scheduling avoids utility demand charges and transformer upgrades.

Tachograph and telematics data support both compliance and energy analytics; state-of-charge, route grade, and ambient temperature drive range prediction.

Cold ambient temperature reduces usable battery energy and increases cabin/defroster load; winter range derating of 20-30% is a planning assumption, not a guarantee.

Axle load limits constrain where batteries can be placed; distributed pack layouts must respect per-axle and gross vehicle weight limits.

Regenerative energy on fixed urban bus routes is significant because of frequent stops; duty-cycle simulation should use measured route profiles.

Mine haul trucks operate on high-torque, high-cycle duty; electrification typically uses trolley-assist or battery swap because static charging dwell is incompatible with continuous haul cycles.

Diesel particulate and NOx exposure is an occupational health driver for underground electrification; removing diesel engines eliminates the primary underground air-quality hazard.

Ventilation load in underground mines is a major energy cost; battery-electric loaders reduce ventilation demand because they emit no combustion exhaust.

Grade and rolling resistance dominate haul-cycle energy: potential energy change is m·g·Δh, recovered only partially by regenerative downhill hauling.

Payload vs. battery mass trade-off applies to loaders and trucks; cycle time and tonnes-per-hour, not peak power, are the productivity metrics.

Extreme dust, vibration, and humidity require IP-rated enclosures and derated thermal management for battery packs and power electronics.

Fire suppression and thermal-runaway detection are critical underground; egress routes and refuge chambers constrain where charging infrastructure can be placed.

Mine electrification interacts with the site grid: peak demand, power factor, and harmonics from large chargers must be engineered into the distribution plan.

Drilling rig power demand is cyclic and peaky (drawworks, top drive, mud pumps); battery hybridisation shaves peaks and lets generators run at efficient steady load.

Energy storage on a rig substitutes for spinning reserve; the control system must respond within milliseconds to prevent blackout during load steps.

Hazardous area classification (e.g., Zone 1/Zone 2) governs where battery packs and chargers may be installed; gas detection interlocks are mandatory.

Rig-site gas (methane) can fuel generators; the same gas is an asphyxiation and explosion hazard, so ventilation and detection design are coupled.

Mud pump power scales with flow rate and pressure: hydraulic power P = Q × Δp, and efficiency losses occur in the pump and motor.

Electrification of drilling replaces diesel-driven mechanical power with electric drives; variable-frequency drives enable precise torque and speed control.

Battery room/container siting must consider blast radius, fire separation, and escape routes; thermal-runaway venting must not discharge into occupied areas.

Wellbore and site logistics: battery containers are heavy and require crane lifts, so transport and rig-up plans must respect lifting and road limits.

LNG is stored cryogenically near -162 °C; boil-off gas (BOG) must be reliquefied, used as fuel, or vented under controlled conditions to avoid overpressure.

Methane slip from gas engines is a potent greenhouse gas; engine and aftertreatment design must minimise unburned methane, not just CO2.

Gas carrier cargo containment and inert-gas systems are safety-critical; oxygen ingress into a hydrocarbon atmosphere creates an explosive mixture.

Last-mile logistics: route density and stop frequency determine whether battery-electric or gas vehicles have lower total emissions per parcel.

Cold chain: refrigeration units draw significant auxiliary power; electric transport refrigeration units reduce local emissions but cut vehicle range.

Hydrogen and CNG storage on vehicles: pressure vessels require periodic inspection, and leak detection is a primary safety barrier.

Fleet charging/depot scheduling for logistics uses overnight dwell; opportunity charging at loading docks extends daily range without extra vehicles.

Emissions accounting should be well-to-wheel, not tank-to-wheel, to compare gas and electric powertrains fairly.

Redundant actuation and power supply are required for L5: loss of a single steering, braking, or power path must leave the vehicle in a safe state (fail-operational).

ODD definition includes geography, weather, road type, speed range, and time of day; operation outside the ODD must trigger a minimal-risk manoeuvre.

Cybersecurity (ISO/SAE 21434) is part of safety for connected L5 vehicles; over-the-air updates require authentication and rollback protection.

Functional safety and SOTIF are complementary: ISO 26262 addresses malfunctions, SOTIF (ISO 21448) addresses performance limitations in the absence of a fault.

Homologation for L5 depends on jurisdiction; there is no single global approval, and national rules differ on driver monitoring and data recording.

Battery management system (BMS) functions: cell balancing, SoC/SoH estimation, thermal control, and isolation monitoring.

Charging standards differ by region (CCS, NACS/Tesla, CHAdeMO, GB/T); connector and protocol choice affects fleet interoperability.

Brake-by-wire and steering-by-wire require a mechanical or electrical fallback; the fallback must be validated against the same safety goals.
