HOW DOES AN ELECTRIC MOTOR WORK?
electric technology and motor components
No cylinders or pistons and no exhaust gases... the motor of an electric car is built based on a set of parts designed to convert electricity into mechanical energy.
The motor uses a current to generate a magnetic field on the static part of the machine (stator), which, as it moves, will set in motion a rotating part (rotor) thus driving the vehicle’s wheels.
Over the last 10 years, focusing on French manufacturing and expertise, Renault has been adapting this technology to today’s and tomorrow’s mobility challenges.

Discover the components of an electric vehicle below.
BATTERY
The battery is the key element of the electric vehicle. It is located under the floor and stores the energy needed for driving. It determines the driving range and charges when the vehicle is plugged into a charging point or domestic socket. Therefore, the vehicle does not need any fuel.
CHARGING SYSTEM
With its various charging options, the charger built into the electric vehicle offers considerable versatility and compatibility with the various existing networks (public and private): 7.4 kW in AC single-phase, up to 22 kW in AC three-phase, up to 130 kW in direct current (DC) for ultra-fast charging points. The CCS* European standard format charging connector (or charging port), located on the vehicle, is protected by a flap. * CCS: Combined Charging System
POWER ELECTRONICS
During driving, the system continuously ensures the transfer and AC/DC conversion of the electrical energy between the traction battery and the electric motor. Conversely, during braking or deceleration phases, the inverter helps to store the kinetic energy recovered by the motor in the battery.
POWERTRAIN
It consists of a motor and a reduction gear that provides the vehicle’s traction by converting electrical energy into mechanical energy that is transmitted to the wheels. Our externally excited synchronous motor (EESM) offers an excellent power-to-size ratio with a high performance of 91%. Its wound rotor design does not therefore have a permanent magnet and does not need rare earths. The reduction gear, with its large operating range, offers linearity and driving comfort at any speed.

Renault Megane E-Tech 100% electric’s CMF-EV platform
This CMF-EV platform is fitted with a 60 kWh ultra-slim battery and a compact 160 kW electric motor. A fully flat floor, a very low centre of gravity, an optimised weight distribution and a longer wheelbase give the car greater agility and interior space.
what advantages?
Renault E-Tech 100% electric is innovative technology providing a unique and intuitive driving experience.
- Up to 300 km WLTP (40 kWh battery) or 470 km WLTP (60 kWh battery)
- Universal charging solutions: AC 7 kW, AC 22 kW, DC 130 kW
- Heat pump and new smart energy recovery system to maximise overall efficiency, and therefore driving range
- Towing capacity (900 kg braked, 750 kg unbraked) and roof box carriage capacity (80 kg)
Renault’s vision for the future
Renault is working on improving the performance of our electric motors. We want to develop more efficient electric motors in order to reduce consumption and therefore improve driving range.
We also plan to intensify production on our French Douai and Cléon sites.
