More Efficient Electric-Car Motor? Startup KLD Claims It Has One

Mass-market plug-in cars have only appeared in showrooms for three years, but startup KLD Energy Technologies thinks it’s already time for a revolution.

KLD says its updated electric motor and battery pack, called OneDrive, can get the same range from a 3-kilowatt-hour battery pack as normal motors get from a 5-kWh pack.

How does the new motor do it? OneDrive uses the same 18650-sized lithium-ion cells (they’re essentially laptop batteries) as a Tesla Model S, but its cells are a different type.

KLD says it uses power cells more similar to those used in hybrid cars, not the energy cells used in other plug-in car powertrains.

Power cells are designed with lower resistance, allowing them to discharge more quickly while generating less heat. This suits hybrids, which cycle their battery packs through a narrow charge range tens of thousands of times.
