EVS: Ample Eo electric vehicle claims "world's first e-quadricycle" title

Called the "world's first e-quadricycle," a small EV from Ample International was on display at the Electric Vehicle Symposium (EVS26) in Los Angeles this week. Named the Eo, the one-seat (or two- or three-seat) vehicle has a maximum speed of 65 kilometers per hour (40 miles per hour) and has a range of 200 km (124 miles), according to a representative at the booth. Ample's Shida Zheng told the Neon Tommy website, that, "It is a four-wheeled motorcycle, completely powered by electricity."

The design is certainly interesting. There are no side mirrors, as the Eo relies instead on backward-facing cameras that pump a live feed into a screen on the left side of the wraparound dashboard. The interior is unlike any other vehicle we've seen, with a driver's seat up front and a flexible space in back that has two seats that can fold down from the sides of the vehicle, sort of like on trains. Since they're directly across from each other, we imagine knees will be touching.

AC Propulsion introducing third-gen Electric Drive System, new motor at EVS26

AC Propulsion, Inc. is introducing the new third generation—Gen 3—Electric Drive System at EVS26. This system features the same 150 kW peak power capability as the Gen 2 system but is updated with revised system architecture and capabilities.

The Gen 3 Power Electronics Unit houses 150 kW inverter and integrated 18 kW battery charger. Click to enlarge.

New features include: reduced size and weight, dual CAN buses and digital system controls. Also new are companion products HVDC-to-12VDC power supply, Battery Pack Control Module and Driver Interface Module. The unique integrated “Reductive” battery charger function is retained which allows up to 18 kW of recharge power for reduced charge time, reduced cost and reduced weight.

Also being introduced is the LCM-150 Liquid-cooled motor. Keeping with the company’s focus on induction motors, this induction machine has the same peak power capability of the AC-150 air-cooled motor (greater than 200 kW), but more than doubles the continuous power rating to 100 kW.
Rotor heat transfer has traditionally been a barrier for higher power applications. The patent-pending design cools the rotor as well as the stator. This greatly expands the application for heavier vehicles.
