Peugeot Plant in France Stops for a Week. The Long-Range Cell Is Not There
A vehicle line does not pause because the order book is empty. It pauses because the cell that matches the long-range version is not on the dock, and the plant cannot build the car the fleet customer ordered. Reuters reported on 29 September that Stellantis will halt Sochaux from 23 to 30 October and Rennes from 22 to 30 October because of limited availability of long-range EV batteries. The company said demand for those versions is strong, particularly among fleet customers, and continues to exceed current supply. It called the stop a one-off to avoid building inventory that does not match demand. The cells come from Automotive Cells Company, the joint venture Stellantis owns with Mercedes and TotalEnergies. The International Energy Agency's Global EV Outlook 2026 put 2025 EV battery deployment at 1.2 TWh, up almost 30% from 2024. China still accounted for over 80% of cell production.
The New Plant Protects the Cell Maker. It Exposes the OEM
George Whitcombe, senior EV analyst at Benchmark Mineral Intelligence, said in written comments to The Supply Chainer that offtake agreements with new cell suppliers come with challenges for automakers, particularly when there is no precedent on ramp-up rates. Several new battery players in Europe are tied to established automakers: PowerCo with VW Group, ACC with Stellantis, and Agratas with Tata. "While this somewhat mitigates the downside for the cell supplier from slow ramp up rates, it can leave the automaker exposed to the situation of lower than expected production from the new facility."
The protection he described is dual sourcing on the models that use the new cells. Verkor cells in Alpine's A390 are restricted to the top-end variant. LG Energy Solution cells go into the standard variant. The all-electric Range Rover will launch with an interim battery supplier, because Agratas, Tata's battery company, will not be producing cells at that stage. Supply from the interim producer is likely to be maintained while Agratas ramps later.
Stellantis Is the Exception. Overcommit Is the Pattern
Whitcombe called the Stellantis situation unique on battery supply arrangements. Automakers detail vehicle production plans, calculate the battery demand that follows, and set offtake from that. "It has been more common for automakers to overcommit regarding battery offtake and consequently not meet their promised volumes." Last year, he said, Ford cancelled a cell offtake agreement with LG Energy Solution that was bound for Ford's European-produced electric commercial vehicles. Securing the right amount of cell supply is a balancing act: avoid the shortage Stellantis is in, and avoid the cost of securing too much.
The Cell That Talks to the Charger Is a Different Problem
The shortage at Sochaux is a vehicle cell that has not ramped. A different battery problem is already being solved at the charger. ENEROC USA and Charging Technologies said on 1 October that ENEROC's LFP forklift batteries now exchange live data with CTI's lithium-capable chargers over a wired CAN bus. When the battery is plugged in, the two devices identify each other. The battery management system sends requested current and voltage, updates as state of charge and cell temperature change, and reports balancing status and estimated time to full. The charger stops or reduces current on a fault or a temperature limit. Operators do not select a manual charge profile. The integration covers CTI's lithium-capable chargers with the CAN option. The Xtreme HF line runs 24 to 80 VDC.
Jeff Franklin, inside sales manager at CTI, said: "Our customers keep a charger in service for many years and count on it every shift, so reliability is the first thing we check in a battery partner. ENEROC builds its packs on CATL cells, known for their exceptional one-per-billion defect rate, and its BMS gave our engineers clean, consistent data to work with." Mark D'Amato, vice president of sales at ENEROC USA, said fleets that already run CTI chargers can move to ENEROC lithium batteries and keep the chargers they have. "Once connected, the battery and charger recognize each other and manage the charge smoothly." That is a warehouse hand-off: the pack and the charger agree on the cycle. It does not put a long-range pack on the Sochaux line.
A week's stop is the cost of a ramp that missed the schedule. The query asked which ramp-up indicators give early warning, and when dual sourcing or a mix change protects the line. Whitcombe's answer is the arrangement itself. An OEM that puts a new cell only on the top variant, or that keeps an interim supplier through the ramp, has already priced the miss. An OEM that ties a plant to one new facility, and then faces fleet demand that outruns the ramp, takes the stop. A 1.2 TWh global deployment does not put a long-range pack on the Sochaux line. The cell that is missing is the one the joint venture has not yet delivered at the rate the vehicle schedule assumed.
