MEV BioRange™ Ethanol Generator Module Series
Renewable-Fuel Range Support for 100% Electric Drive Platforms
The MEV BioRange™ Ethanol Generator Module Series is a conceptual range‑extender system engineered to preserve pure electric drive while adding renewable‑fuel charging capability. Each module uses an ethanol‑powered generator to supply energy to the high‑voltage battery—never the wheels—maintaining the smooth, instant‑torque driving experience of an EV.

Designed for rural mobility, off‑grid travel, emergency backup, worksite reliability, and long‑range independence, BioRange™ expands the usefulness of MEV platforms without compromising electric propulsion.

How BioRange™ Works — Series Hybrid Architecture
Energy Path:
E85 / Bioethanol Tank → Ethanol Engine → Generator → HV Battery Pack → Electric Drive Motor → Wheels

The ethanol engine operates only as a dedicated generator, running at an optimized, efficient RPM.
The wheels remain 100% electric‑driven, preserving MEV’s core design philosophy.

BioRange™ Module Lineup
Single‑Cylinder BioRange™ Module
Compact. Lightweight. Purpose‑Built for Small Platforms.
The Single‑Cylinder BioRange™ Module is the entry‑level generator system designed for:

Micro‑mobility EVs

Compact utility vehicles

Camper support systems

Emergency backup charging

Lightweight off‑grid applications

This module uses a single‑cylinder ethanol engine tuned exclusively for generator duty. It never connects to the drivetrain and activates only when the battery requires supplemental charging.

Key Advantages
Compact footprint

Lower weight

Simplified mechanical layout

Reduced manufacturing complexity

Ideal for emergency or occasional charging

Perfect for small EVs, campers, and utility platforms

This version represents the lightweight, efficient side of the BioRange™ family.

Twin‑Cylinder BioRange™ Module
Smoother. Stronger. Built for Larger EV Platforms.
The Twin‑Cylinder BioRange™ Module delivers higher output and smoother operation for:

Compact trucks

Light‑duty utility vehicles

Worksite and jobsite platforms

Camper and towing applications

Extended rural or off‑grid travel

Its balanced twin‑cylinder ethanol engine provides more consistent generator performance with reduced vibration, making it ideal for longer runtime and higher charging demand.

Key Advantages
Smoother, quieter operation

Lower vibration

Higher charging capability

More stable power output

Optimized for larger EV platforms

Stronger support for utility and camper applications

This version represents the high‑capability BioRange™ solution.

E85 / Bioethanol Fuel Integration
Both BioRange™ modules are designed around E85 or bioethanol, offering:

High‑octane renewable fuel

Cleaner combustion characteristics

Local production potential

Stable generator‑optimized operation

Because the engine never responds to wheel load, it can run in a narrow, efficient RPM band, maximizing fuel economy and minimizing emissions.

Design Purpose & MEV Philosophy
The MEV BioRange™ series explores how renewable liquid fuels can support electric mobility without compromising:

Electric‑only wheel drive

Smooth EV performance

Quiet operation

Modular platform scalability

Real‑world usability in demanding environments

The Single‑Cylinder Module focuses on compact efficiency.
The Twin‑Cylinder Module focuses on higher output and extended capability.
Together, they form a scalable BioRange™ ecosystem adaptable across MEV platforms.

Concept Summary
The MEV BioRange™ Ethanol Generator Module Series is a practical bridge between:

Full electric mobility, and

Renewable‑fuel energy independence

It enhances range, supports off‑grid travel, strengthens emergency readiness, and expands the operational envelope of MEV vehicles—while keeping propulsion 100% electric.
