Elaphe’s In-Wheel Propulsion is in EU-LIVE L5e Demonstrator Vehicle



Elaphe Propulsion Technologies, a technology company and leading developer and supplier of in-wheel electric propulsion for battery-electric and hybrid vehicles, announced the recently released EU-LIVE L5e demonstrator vehicle uses Elaphe’s in-wheel electric propulsion.

The EU-LIVE L5e demonstrator vehicle was built within the Horizon 2020 GV5 Research and Innovation programme, coordinated by Virtual Vehicle, and developed by renown PSA Groupe, Peugeot Scooters, Continental, Samsung SDI, Brembo, Elaphe and many others.

The main objective was to showcase an innovative vehicle and underlying technology, suited for both concentrated city driving as well as speeding down highway roads. As the project focuses on multiple L-Class vehicles, the goal was to use as many modular components as possible, to maintain maximal cross-platform functionality and reduce production costs.

The L5e runs in zero-emission mode with exceptional acceleration, and the 48-volt battery, designed by Samsung SDI, can be recharged using highly-efficient regenerative braking, as the in-wheel motors have the ability to directly regenerate at the wheel level in the optimal range of operation.

The mechanical disc brake system, required for scenarios where larger braking torque is required, such as emergency cases, was designed and built by Brembo S.p.A. And consists of an innovative aluminum caliper integrated in the motor’s stator, resulting in superior motor compactness.

The vehicle’s small footprint (2.4 meters x 0.85 meters) and upward-rotating doors facilitate perpendicular parking and free up road space. Besides an enclosed, heated cabin, the vehicle also features seatbelts and an airbag, making helmets, gloves, waterproof jackets and other protective gear, well known to motorcycle riders, unnecessary.

Elaphe presented its autonomous applications focused in-wheel propulsion platform at CES 2018.

Elaphe Propulsion Technologies, a technology company and leading developer and supplier of in-wheel electric propulsion for battery-electric and hybrid vehicles, announced a cutting-edge in-wheel electric motor at CES 2018.

It is an integral part of a working L5e demonstrator vehicle developed together with Groupe PSA and a consortium of 12 partners from six countries. The technology is intended to be industrialized with possible start of production as early as 2020.

Elaphe partnered with Brembo S.p.A. (that supplies brakes for Tesla) to design and manufacturer a fully integrated and extremely compact in-wheel drive solution for light electric vehicles.

The Brembo – Elaphe joint development effort resulted in a modular, air-cooled in-wheel electric motor, which pumps out an astonishing 256 Nm of direct torque (no gearbox necessary), delivering upwards of 25 kW of power per wheel.

The motors are designed to fit into the rear wheels of L-class vehicles. Directly-driven wheels vastly simplify the use of tilting mechanisms, as the vehicle does not require any mechanical transmission.
