5 terms

flywheel technical

"integrates the flywheel and the engine crankshaft through a rigid coaxial"

A flywheel is a self-reinforcing business process where one positive result makes the next one easier, creating momentum that builds over time—like pushing a heavy wheel that spins faster with each steady shove. For investors, a strong flywheel suggests durable growth and lower marketing or retention costs because customer gains, efficiencies, or product improvements feed back into more gains, making future revenue harder for competitors to displace.

range extender technical

"YCY24-65kW Flywheel Range Extender System (YC-FRS) has been launched"

A range extender is a secondary power source—often a small engine or generator—that recharges an electric vehicle’s battery or supplies electricity when the main battery is low, extending how far the vehicle can travel between charges. For investors, it matters because adding a range extender can change a vehicle’s market appeal, production costs, fuel and maintenance profiles, and regulatory treatment, all of which affect revenue potential and competitive positioning.

regenerative braking technical

"Additional benefits include low operating noise, regenerative braking, and priority"

Regenerative braking is a vehicle system that captures energy normally lost as heat when slowing down, converts it into electricity, and stores it in the vehicle’s battery. Think of it like a bicycle dynamo that charges a light while you brake; for investors, this means better fuel or battery efficiency, longer driving range, lower operating and maintenance costs, and potentially smaller batteries or improved vehicle performance—factors that affect vehicle economics and product competitiveness.

new energy vehicles technical

"priority road access reserved for new energy vehicles. The YC-FRS also addresses"

New energy vehicles are cars and light trucks that use electricity or alternative fuels instead of relying only on gasoline or diesel, including battery electric vehicles, plug-in hybrids, and hydrogen fuel-cell models. Investors watch them because they signal shifts in consumer demand, regulation, and supply chains—like swapping an old phone for a smart one—and that shift can change sales, raw-material needs, and company valuations across automakers, battery makers, and component suppliers.

powertrain technical

"next–generation, new–energy powertrain technologies and strengthening collaboration"

Powertrain is the collection of parts that generate and deliver motion in a vehicle — typically the engine or electric motor, transmission, driveshafts, axles and related control systems or batteries in electric models. It matters to investors because powertrain design and efficiency drive fuel economy, performance, production cost, regulatory compliance and warranty risk, all of which affect a maker’s competitiveness, profit margins and exposure to supply-chain or technology shifts; think of it as the vehicle’s heart and muscles.
