Designed for the city and beyond, Renault 5 E-Tech electric offers a choice of motors and batteries, reflecting the intended use of the car. With a power output of up to 110 kW / 150hp, a range of up to 400km / 248miles WLTP and DC charging up to 100 kW, it has all the qualities of a larger car, whilst maintaining its lightness and agility. A rarity in the electric city car segment, it can even tow a trailer, with a towing capacity of 500kg.

Two battery options
Renault 5 E-Tech electric will be available with two lithium-ion batteries. The biggest, which will be the only one available at market launch, has a capacity of 52 kWh and a range of up to 400km/ 248 miles WLTP. The second has a capacity of 40 kWh for a range of up to 300km / 186 miles WLTP. Both use NMC (Nickel Manganese Cobalt) technology, for the best energy density on the market today.

These battery modules are designed to improve energy density without increasing size. The 52 kWh battery includes four large modules in its casing, compared with the 12 smaller modules found on Megane E-Tech electric and Zoe. This simplified architecture brings weight savings of 20kg compared with Zoe. A total of 46 cells are assembled in each of the four modules, each weighing around 55kg.

The 40 kWh battery has just three large modules in the same casing. Each of these three modules includes 31 cells of increased thickness, weighing in at around 240kg.

For improved performance in all conditions, the battery is equipped with a liquid cooling system to regulate its temperature. For greater safety, the cooling fluid does not circulate inside the casing but through the extruded floor. Finally, when charging the vehicle, charging time can be optimised by pre-conditioning the battery and planning the journey using Google Maps.

Two motor power ratings

The electric motor of Renault 5 E-Tech electric uses Renault's preferred technology: wound rotor synchronous. As it has no permanent magnets, it uses no rare earths, thereby reducing its environmental impact. The magnets are replaced by copper coils, with the wires being ordered and routed in such a way as to withstand the centrifugal force of the rotor.

Based directly on the motor of Megane E-Tech electric and Scenic E-Tech electric, Renault 5 E-Tech electric also benefits from the experience acquired with other electric motors, such as on Zoe, in terms of durability. It also gains several new features, including new-generation power electronics (inverter) and reworked reduction gear. The difference can be seen in size and weight. The motor is 15kg lighter with a rotor that has been made 3cm shorter to fit under the bonnet of Renault 5 E-Tech electric.

The AC/DC converter, transforming the 400V from the battery to 12V, and the accessory box managing power distribution, have been integrated into the charger in order to save space. The new powertrain weighs just 105kg, including the charger.

The motor is available with two power ratings: 110 kW (150hp / 245Nm) or 90 kW (120hp / 225Nm). The 110 kW motor is paired with the 52 kWh battery, while the 90 kW motor is paired with the 40 kWh battery. The first motor will be available at launch, with the other following at a later date.

For the 110 kW version, Renault 5 E-Tech electric accelerates from 0 to 62 mph in under 8 seconds and from 50 to 75 mph in under 7 seconds.

11 kW AC bidirectional charging
Renault 5 E-Tech electric will be the first in a long series of cars to be fitted with the new 11 kW AC bidirectional charger featuring V2L (vehicle-to-load) for connecting a device to the vehicle battery and V2G (vehicle-to-grid) for feeding electricity back into the grid and saving on home charging.

This 11 kW AC bidirectional charger will be operational on both the 110 kW and 90 kW versions. The 11 kW charger fitted on all versions makes Renault 5 E-Tech electric even more versatile, ready to take to the road in any UK city.

With an 11 kW AC charging point, the 52kWh battery will take 4hrs 30 minutes to charge from 10% to 100%. The 40kWh battery will take an hour less.

DC charging up to 100 kW
For DC fast charging, the 110kW powertrain has a 100 kW DC socket to charge the 52 kWh battery. The 90 kW powertrain is equipped with an 80 kW DC socket to charge the 40 kWh battery. In both cases, it will take just 30 minutes to charge the battery from 15% to 80%.
