The Renault 5 E-Tech has two battery packs defined by usable energy of 40kWh and 52kWh. Initially the vehicle is launched with the 52kWh usable pack. This pack is assembled by Ampere, a subsidiary of Renault and using AESC pouch cells.
- Energy Density
- Gravimetric ~ 185 Wh/kg

- Usable Energy = 52 kWh
- Total ~ 55 kWh
- SoC usable window ~ 95%
- Configuration
- 92 s
- 2 p
- Total #cells = 184
- Peak ~ 124 kW10s
- Pack Mass = 297 kg [3]
Charging
- Fast Charging = 100 kW
- 15-80% = 30 minutes
- 10-80% = 33 minutes
- V2G
- 11 kW AC bidirectional charger
- V2L
- 3.7kW
Thermal
- Liquid Cooling
- Pre-conditioning for DC charging
The liquid cooling circulates through the “extruded floor” of the battery enclosure.
Structural
It appears that Renault Ampere have made the decision to include the side crash structure in the seat rails and not add crossbeams inside the battery enclosure.
advantage of the all-electric design of the AmpR Small platform is that the seat crossmembers have been specially designed to protect the battery without the need for reinforcements inside the body, freeing up maximum space for the cells

The Renault 5 E-Tech battery pack compares very well with other battery packs in the database.
Safety
The safety features quoted by Renault are the Fireman Access and Pyroswitch:
- SD pyro switch; disconnect the battery from high-voltage network to ensure safety as needed
- fireman access; hatch designed to flood the battery quickly if needed to contain and control battery fire

Is Renault 5 “Pre-conditioning for DC charging” done via electric heating pads/rods/cables or via liquid ?
the battery is liquid cooled and heated, the fluid (water glycol) is heated / cooled by the heat pump and via a heat exchanger
I have Renault 4 now and I can confirm it. And the power of preheating heater is 9kW, so it is pretty fast. Usually it heats battery to 5-10degC temperature and then it stops heating (CarScanner)
