New Rolls-Royce small turbine to begin tests to advance hybrid-electric flight

Green Car Congress

Rolls-Royce announced its new small gas turbine that has been specifically developed to power hybrid-electric flight is set to begin testing. The engine is part of a turbogenerator system that is being developed for the Advanced Air Mobility market. The turbogenerator can be used in serial or parallel hybrid applications.

Researchers Demonstrate Autonomous Underwater Vehicle With Novel Thermal Recharging Engine

Green Car Congress

NASA, US Navy and university researchers have successfully demonstrated the first robotic underwater vehicle to be powered entirely by ocean thermal energy. This expansion/contraction produces a high pressure oil that can be collected and periodically released to drive a hydraulic motor for electricity generation and battery recharging.

Rolls-Royce developing turbogenerator technology for hybrid-electric aviation applications

Green Car Congress

Rolls-Royce is developing turbogenerator technology—including a new small engine—designed for hybrid-electric aviation applications. The turbogenerator will recharge batteries after take-off or power propellers directly, enabling aircraft to switch between power sources in flight.

Why is maintaining 80% battery power the best choice for EVs? | EV Basics

Setec Powerr

You’ll stop and power up before hitting zero miles, but let’s keep things simple and say 240. If the 0-to-80% recharge time is 40 minutes, you can hit the road in less than half an hour, which is not too bad. If you want to replenish the battery fully, it could take 90 minutes to go from 80 to 100%.

Tech: How do Hybrid & Plug-in Hybrid Batteries Recharge? Do I Need to Plug a Hybrid In?

Clean Fleet Report

Fast-forward about 10 years and a new type of hybrid came on the scene—the plug-in hybrid, and it does require plugging in to charge the onboard battery to maximize efficiency (without plugging in it functions like a normal hybrid). In addition, when in the generator mode, the internal combustion (usually gas) engine charges the battery pack.
