Building hybrid engines is a complex engineering task. It requires two main components—an electric motor to power the drivetrain, and a software based controller to switch between fuel, electric drive and charging modes. Designing it as a retrofit solution common to multiple vehicle classes and manufacturers, made the problem doubly complex. Altigreen’s kit has a proprietary motor-generator at its heart and integrated power electronics for torque assist and regeneration, with complex model-based control logic, as its brain. “Being a fuel agnostic solution, it works with petrol, diesel, and CNG engines. Further, our patented designs create a smaller form factor resulting in lower material cost, greater ease of installation and reduced space requirement,” articulates Moklegaard.

“Increase mileage by over 20 percent and reduce emissions similarly, at $1,000—now that’s a game changer,” adds Gupta excitedly.
To keep tight control on quality, the retrofit kit has been split into multiple proprietary components, manufactured by an ecosystem of vendor partners. The kit was rigorously tested and calibrated for two years on multiple vehicles including petrol and diesel sedans and small trucks—collecting valuable data for future enhancements. “In its fifth version, we have further improved the electronics package and fine-tuned the energy regeneration capabilities,” explains Moklegaard. Altigreen is successfully piloting its kit with Carzonrent, a premier car rental company in India, as well as the intracity distribution fleets of beverage and ecommerce companies like Coca- Cola and UrDoorStep.
“It’s a multi-billion dollar automotive industry, with car sales growing over 12 percent CAGR, projected to cross 250 million vehicles across the developing countries in the coming decade,” estimates Saran. The company is already seeing keen demand for its solution. Altigreen aims to install the kit into passenger vehicles as well as hundreds of more fleets of taxis and LCVs in the coming years. Also, “we’ll be expanding our footprint across the cities of South America and South Asia like Bangkok, Kuala Lumpur, Manila, Jakarta, Colombo, Sao Paolo, as well as within the high-traffic urban centers of U.S. and Europe,” concludes Saran.
