The LEV50 packs in these vehicles are aging, and original replacement cells are increasingly hard to source. The chassis and drivetrain still have useful life, so the practical decision is whether to keep patching individual vehicles as failures appear or modernize the battery supply across the fleet in one planned program. For a technical lead, the immediate task is to gather the right vehicle and battery data, identify which vehicles to prioritize, and submit a bulk battery inquiry that a supplier can act on. A supplier of NMC replacement cells can respond with sample options, batch orders, and bulk supply once the fleet data is organized.
Why Older i-MiEV, iOn, and C-Zero Fleets Face a Replacement Supply Gap
The replacement supply gap has little to do with the cars’ condition and everything to do with the age of the battery format. The LEV50 cell was a bespoke part for a small family of Mitsubishi, Peugeot, and Citroën EVs. Global battery production now concentrates on current EV platforms, so older cell formats have moved out of the mainstream. The IEA’s Global EV Outlook 2024 documents rapid growth in EV sales and battery demand worldwide. For fleets, the result is concrete: when a pack needs attention, the original cell is not always available in a realistic time frame or at a cost that makes sense for the vehicle. That supply gap creates a second problem. A fleet can replace occasional modules for a while, but once multiple vehicles show the same capacity loss, the patch-and-repair route becomes unpredictable. One car might need two cells, another an entire module, and a third a BMS that is throwing faults. Without a fleet-level view, parts are ordered vehicle by vehicle and every order starts from scratch. For this reason, treating LEV50 packs as a modernization project makes more sense than chasing original parts one order at a time: evaluate the vehicles, understand what the fleet needs, and source replacement cells in volume.
Assessing Battery State and Fleet Use Patterns Before Planning an Upgrade
Before ordering replacement cells, evaluate which vehicles warrant them. Battery health depends on how each car has been used and charged. A vehicle fast-charged daily in a hot climate degrades differently from one slow-charged overnight in a temperate garage. Repeated full discharges, long periods parked at high state of charge, and frequent high-rate charging all accelerate capacity loss. The visible symptoms vary as well: reduced range, sudden state-of-charge drops, charging interruptions, or an increasing number of warnings from the pack. The original BMS in these vehicles was calibrated around the LEV50 cell’s voltage window, capacity, and charging limits. Swapping in a different cell without evaluating the BMS is unsafe. A qualified EV battery technician should read the pack data, check cell voltages and internal resistance where possible, and confirm which vehicles are structurally sound and economically worth upgrading. The U. S. Department of Energy’s battery resources describe the general principle that EV battery life depends heavily on operating conditions and charging behavior, which is why fleet usage data matters more than model year alone. Fleet use patterns also decide the order of work. A vehicle running a fixed daily route with no spare capacity should be near the top of the list; a backup car covering a few kilometres a week can wait. The same battery data that helps a supplier quote also helps sequence the work so the fleet remains operational while upgrades happen.
Preparing a Useful Fleet Battery Inquiry for NMC Replacement Supply
Once the vehicle list and battery data are in hand, the inquiry becomes straightforward. A useful bulk battery request tells the supplier three things: exactly which vehicles are involved, what the packs are doing, and what the fleet expects from the upgrade.
1. Build a Complete Asset List by Vehicle Model and Model Year
Start with a spreadsheet of every candidate vehicle: model, model year, mileage, and battery pack designation where available. Mitsubishi i-MiEV, Peugeot iOn, and Citroën C-Zero use the LEV50 family, but regional versions and model years can differ in details. The replacement option available from NOGI Battery is a CATL 93Ah NMC prismatic cell designed for LEV50 packs. Its dimensions are 172×42×85mm against the LEV50’s 171×44×98mm, so the height difference is handled with an epoxy riser. Terminal details also need checking, including the M8 stud and M3 hole positions. Confirm the pack version and terminal details with the supplier before ordering.
2. Prioritize Vehicles by Battery Health and Failure Symptoms
For each vehicle, record what the battery is actually doing: fault codes, charging interruptions, range loss compared with the original rating, and technician notes from recent inspections. A pack with a single weak module may need a smaller intervention, while a pack with uniformly degraded cells is a better candidate for a full LEV50 replacement with the 93Ah cell. Sharing this data also helps the supplier plan batch sizes. Every vehicle should still have its BMS evaluated by a qualified EV battery technician before ordering, but the records provided upfront turn a vague quote request into a useful one. The third part of the inquiry is the intended use and capacity expectation. State how each vehicle will be used after the upgrade. A shuttle running two daily shifts has a hard capacity requirement; a spare vehicle with sporadic trips has a much lower one. The CATL 93Ah cell stores roughly 86% more rated capacity than the original LEV50’s 50Ah, which gives planners a practical reference point. Route, heating, and vehicle condition all affect real-world range. Include expected daily mileage, charging window, and climate in the inquiry. That tells the supplier whether the standard 93Ah configuration fits, how many cells to plan for, and whether sample validation is needed before bulk supply.
Conclusion
Running an older EV fleet is a different exercise from repairing one car. These vehicles still have useful life in their bodies, suspension, and drivetrains; the LEV50 battery is often the single component that decides whether they stay in service. A fleet-level approach starts with a clear asset list, builds on battery health and charging data, and translates into an inquiry a supplier can act on. That is how a collection of aging EVs becomes a planned modernization program instead of a series of emergency repairs. If the LEV50 packs are affecting fleet reliability, put together the vehicle list and battery records, then contact NOGI Battery about the CATL 93Ah NMC replacement cell, sample options, batch orders, bulk supply, customization, and international shipping.
FAQ
Q：Which older EV models can use the CATL 93Ah cell for fleet-level battery upgrades?
A：The CATL 93Ah NMC prismatic cell is offered as a replacement/upgrade option for the Mitsubishi i-MiEV, Peugeot iOn, and Citroën C-Zero running LEV50 packs. These three models make up the core of that generation of small EVs, but each vehicle’s model year, pack version, and condition must still be checked. The cell measures 172×42×85mm and requires an epoxy riser to reach the original 98mm height. Each vehicle also needs its BMS evaluated by a qualified EV battery technician before ordering.
Q：What vehicle information should a fleet operator provide when requesting a bulk battery quote?
A：Provide a complete vehicle list with model, model year, mileage, and battery pack designation where available, plus battery health records such as fault codes, range loss, charging interruptions, and technician inspection notes. Describe how each vehicle is used, including daily mileage and charging patterns. That lets the supplier confirm fit, plan batch sizes, and discuss sample or bulk supply. The CATL 93Ah cell is the reference option, but the practical starting point for a useful quote is the vehicle and pack data you bring to the conversation.
Q：Does upgrading an EV fleet battery create disposal responsibilities for retired packs?
A：Yes. Retired EV battery packs and their cells should be routed to approved collection, recycling, or second-life channels rather than regular waste streams. The European Commission’s batteries guidance describes the EU’s framework for battery collection and recycling, and similar extended producer or owner responsibilities exist in many markets. Fleet operators is worth checking the local rules for their region and work with a licensed recycler when decommissioning LEV50 packs.
