Behind the scenes of the assembly of Peugeot’s electrified models

PEUGEOT has lifted the lid on its growing team of technicians who are responsible for assembling and testing each and every battery that goes into its electric cars (100% electric or Plug-in Hybrid) and vans.

PEUGEOT’s electrification is accelerating in 2022 with the new 408, which is set to strengthen the brand’s Plug-in Hybrid offering, also reinforced by the recently launched new 308. In 2022, more than 70% of the PEUGEOT range sold worldwide is electrified. In Europe, the brand’s electrified models represent one passenger car out of four in H1/2022, up from one out of every six in 2021.

By 2025, 100% of PEUGEOT model line-up will offer an electrified variant. This will require a substantial uplift in the number of batteries being produced. PEUGEOT estimates it will assemble up to 10,000 batteries a month for its car range by next year, and as many as 7,000 batteries a month for its LCV range.

It takes roughly 60 minutes for the technicians to assemble each 50kWh battery unit. 90 minutes are necessary for the larger 75kWh units. The team subjects each battery to a series of critical tests, allowing each unit to be guaranteed with an eight-year / 100,000 miles warranty policy for 70% of its charge capacity.

The testing process is mandatory to sign off the batteries for the assembly:

  • The first test simulates operation of the battery in a vehicle to validate reliability
  • A performance test stimulates the battery at full rate
  • The last test is a sealing test. The battery unit is pressurised by gas to check for leaks by monitoring pressure loss. A proper seal will prevent water or dirt from getting inside the battery cells and compromising its lifecycle or performance.

Operators work in the dedicated battery assembly workshops of five plants of the Stellantis Group: Vigo & Saragossa (Spain), Trnava (Slovakia), Sochaux & Mulhouse (France) and Hordain (France). Both electric and conventional combustion engine vehicles are assembled on the same line.

The technicians who test and assemble the PEUGEOT vehicles’ batteries come from Stellantis’ factories. They are selected on the basis of their electrification skills and are given month-long specialist training.
