Formosa EV is a modular electric vehicle (EV) conversion ecosystem designed for builders, restorers, and shops. We combine OWEM-grade engineering with open-source flexibility, offering components which are modern, reliable, and scalable. Whether you're a DIYer or a professional shop, our systems are built to simplify your build and grow with your needs.
DIY Enthusiasts: First timers or hobbyists who want clear guides, gplug-and-play parts, and affordable modularity.
Restoration Shops: Professionals preserving classic cars but needing modern, heritage-compatible EV compnents.
EV Conversion Shops: Business requiring scalable, compliant systems to reduce build time and costs.
Builder-Centric Design: Wide component support, plug-and-play integration, and modular upgrades.
Tested by Pros: Systems are road-proven and shop-validated.
Taiwan-California Fusion: Precision engineering meets hands-on car culture.
No Salvaged Parts: All components are brand new with modern EV technology.
Our Promise:
OEM Quality: Products that exude precision craftsmanship and engineering.
Human-Centered Design: Intuitive systems that just work, are “nice” to use, and beautiful to showcase.
Built for the long haul: Future-proof builds that work for decades and upgradable if desired.
We're launching four foundational products to kickstart your build:
Liga VCU: The “brain” of your EV: App-controlled, CAN-free vehicle control unit.
Liga Harness: Custom-fit wiring: Machine-crimped, 100% OEM-compatible harnesses.
Forte Motor: 130kW powerhouse: Integrated inverter, pre-wired HV cables (TECO TP130).
SOL HV Battery: Modular power: Enclosed, BMS-equipped packs (8–16 modules).
The Formosa MasterStack will expand to include:
Brisa HVAC Kits (cabin heating/cooling, battery thermal management).
Ria Power Flow upgrades (ultra-fast chargers, smart power distribution modules).
High-power Sol Battery Packs (824V configurations).
Advanced Liga Displays (driver dashboards, customizable interfaces).
The Formosa MasterStack is divided into 5 layers:Liga (controls), Sol (battery), Ria (Power Flow), Forte (motor), Brisa (Thermal). Mix and match components or start with a core kit. Scale as you grow.
Yes! Our systems are model-agnostic and designed for:
- classic cars and trucks.
- Manual or automatic transmissions.
- 12V/ 24V systems.
Provided custom wire harnesses, and CAD files ensure seamless integration.
Detailed Installation Guides: Step-by-step instructions and videos, wiring diagrams, spec sheets.
CAD/DBC Files: For custom brackets or integrations (request via email).
Community Forum: Collaborate with other builders and Formosa engineers.
