An electric vehicle in a compound is not a static asset. An internal combustion unit parked for sixty days is the same unit when it leaves; a battery-electric unit parked for sixty days may have drifted out of the window its carrier will accept, or into a state that needs a dealer to recover. That changed character in January 2026, when battery-powered vehicles moved into the dangerous goods framework and state-of-charge limits shifted from recommendation to enforced requirement. It got harder at the same moment dwell got longer — battery-electric registrations fell sharply through 2025 and into 2026, which means units sit for longer and volume no longer hides handling mistakes. The compound now has to manage a value that changes on its own, per vehicle, against several different targets. Request the integration datasheet to see how that gets tracked at VIN level.
FVL · BEV OUTBOUND
Outbound Logistics for Electric Vehicles
Air: ≤30%
Sea: 30–50%
Storage: 50–60%
Three targets, barely overlapping. The right one depends on what happens next.
The Windows Conflict — and That Is the Whole Problem
Each figure is defensible on its own terms. Together they mean a single fleet-wide charge policy is wrong for somebody, every time.
Air freight: 30% or below
Under the current dangerous goods regulations for air, any vehicle with a battery above 100 watt-hours must be at or below 30% state of charge. A unit arriving at the terminal at 50% is rejected outright.
Verified physically during inspection
Sea and RoRo: commonly 30–50%
Most major vehicle carriers now require the traction battery held within that band, alongside a declared battery condition. The exact requirement varies by carrier and destination, so eligibility has to be confirmed before booking rather than assumed.
Confirm per carrier, per lane
Storage: around 50–60%
The consensus across battery researchers and manufacturers is that lithium-ion cells stored around 50 to 60% experience the least calendar ageing, because internal electrochemical stress is lowest there. For storage beyond a couple of weeks, 40 to 60% is the commonly cited target.
Best for the asset, wrong for the flight
Read those three together and the operational requirement falls out on its own. The correct charge for a unit depends on its next movement and how long it waits for it — which means charge management has to be driven by the dispatch plan rather than set as a standing rule at the gate.
What Changed on 1 January 2026
Two things shifted at once, and the second is the one catching operations out.
← Swipe to see all columns →
| Change | What it means | Operational consequence |
|---|---|---|
| New UN classification | Battery-powered vehicles reclassified from the previous designation to UN 3556 for lithium-ion, with separate numbers for lithium-metal and sodium-ion | Brings them into the dangerous goods framework, with stowage requirements away from heat sources and updated declarations |
| Charge limit became mandatory | The air limit moved from recommendation to enforced requirement, with standardised enforcement across carriers | Cargo that shipped successfully in 2025 can be rejected in 2026 with identical packaging and paperwork |
| Carriers hardened acceptance | Following a run of vehicle-carrier fires attributed to lithium-ion batteries | Upgraded suppression, restricted stowage locations, and stricter pre-booking conditions |
| Verification became physical | Charge state checked during dangerous goods inspection rather than taken from the declaration | A declared figure that does not match the vehicle is found at the terminal, not in the paperwork |
The dangerous assumption
Published guidance names it directly: assuming that successful shipments in 2025 guarantee compliance in 2026 is the error to avoid. Nothing about your process needs to have changed for it to start failing — the enforcement did. Any lane that has not been re-confirmed since the turn of the year is running on an assumption rather than a check.
Three Things That Stop a Booking, None of Them Charge
Charge gets the attention. These three refuse the unit just as effectively, and every one of them is a records problem rather than a battery problem.
01
An active warning light
Carriers require no active warning lights on the vehicle. A unit that developed a fault during dwell — and battery-electric vehicles run background systems while parked — can present at loading with a lamp nobody has looked at since it arrived.
02
An open recall
Most carriers refuse the booking outright where a recall is outstanding, with the repair required first. This turns campaign status into a shipping gate rather than a quality matter — and a unit with an open campaign is not a unit awaiting rectification, it is a unit that cannot leave.
03
A battery condition that has not been declared
Declared battery condition sits alongside charge state in carrier requirements. That declaration has to come from somewhere, and on a compound holding several hundred units it comes from a record rather than from an inspection on the morning of loading.
Note what those three have in common. None is discovered by looking at the vehicle at dispatch — each requires knowing something about the unit's history, and each one turns a booked slot into a returned vehicle when it surfaces late. Carrier capacity is not cheap enough in this market to spend it on units that were never eligible.
?
State of charge, unit 4471, right now
Most compounds cannot answer that without walking to the vehicle.
Which is manageable at ten units and impossible at four hundred. Bring a list of the battery-electric units currently in your compound to a 30-minute session and we'll map them against their dispatch plans in Fleet Rabbit — showing which are outside the window they will need, which are drifting toward trouble, and which are blocked for reasons that have nothing to do with charge.
The Compound Is Not a Car Park
Four things happen to a parked battery-electric vehicle that do not happen to a parked internal combustion one. The last is the expensive one.
It draws power while parked
Unlike a vehicle with a simple key-off state, these maintain cellular connections, run background software processes and keep electronics active. Charge falls during dwell as a matter of design rather than as a fault.
Self-discharge continues regardless
Side reactions inside the cells continue even with nothing switched on, and the rate rises with temperature — a common rule of thumb has many of those reactions roughly doubling for every ten degrees above room temperature.
Heat and high charge compound each other
Storage ageing is driven by temperature and charge state together, with high temperatures and high stored charge accelerating capacity loss. A summer compound holding units at high charge is running the worst combination available.
And a flat unit may need a dealer to wake up
If the high-voltage pack drops too low, the battery management system can enter a protective shutdown. Recovering from that state can require a dealer visit, and in extreme cases permanent capacity loss occurs. A vehicle left at a low charge without recharging can drift into over-discharge purely through slow self-discharge — which is a brand-new unit needing intervention before it has been sold.
Slower sales made this harder, not easier
Battery-electric registrations fell sharply after incentives lapsed — roughly a quarter year on year in late 2025, with first-quarter 2026 registrations down again — and the industry observation is pointed: a slower transition makes careful handling of each vehicle more important, because units dwell longer and volume no longer hides mistakes. Lower throughput means every unit sits closer to the edge of its window.
Top Five Practices
Five, ordered by how much they change on Monday morning.
1
Set the charge target from the dispatch plan, not the gate
A unit shipping by sea next week and a unit storing for two months need different charge states, and neither matches the air limit. Drive the target from the intended movement and its date, and re-derive it whenever the plan changes — which on a compound is often.
2
Track charge as a value that decays
Record it at gate-in and re-check on an interval rather than treating the arrival figure as the current one. Charge drifts downward continuously through background draw and self-discharge, faster in heat, and the drift is what puts a compliant unit outside its window without anybody touching it.
3
Set a floor alert well above the danger zone
Not at the shipping minimum — well above it, because the cost of crossing the lower boundary is a protective shutdown and a dealer visit rather than a rebooking. This is the single highest-value alert on a battery-electric compound and it protects the asset rather than the schedule.
4
Screen for the non-charge blockers before booking
Warning lights, open campaigns and battery condition declaration, checked before the slot is taken rather than at the ramp. Confirm carrier and destination requirements at booking too, since they vary and have been changing.
5
Hold the chemistry against the VIN
Because the storage rule is not universal, as the next section covers. A single fleet-wide charge policy applied across mixed chemistries is wrong for part of the yard by definition.
One Policy Does Not Fit the Yard
The point most storage guidance skips, and it matters as soon as a compound holds more than one manufacturer or trim.
The 50–60% guidance assumes a chemistry
It reflects the behaviour of the widely used lithium-ion chemistries, where both very high and very low storage charge accelerate permanent capacity loss.
Lithium iron phosphate behaves differently
It is more stable at high charge and does not carry the same degradation penalty at the top of its range — with at least one manufacturer recommending charging such vehicles to full regularly, and even before storage. Applying a mid-charge storage rule to those units is not conservative, it is simply the wrong instruction.
Which makes chemistry an operational field
Not a specification detail. If your compound cannot answer which chemistry a given VIN carries, it cannot apply the correct storage policy to it — and the information exists, it simply has to be captured at intake rather than looked up per vehicle later.
Charging at the Compound
Five decisions, and the first one determines whether the rest are affordable.
Size for maintenance, not for turnaroundCompound charging exists to hold units inside a window, not to fill them. Topping several hundred vehicles from low to mid charge occasionally is a very different electrical requirement from fast-charging any of them, and sizing for the wrong one is expensive.
Prioritise by dispatch date and driftCharging capacity is finite, so the queue should be ordered by which units are closest to falling out of their window or leaving soonest — not by which are nearest the outlets.
Treat temperature as part of the planStorage ageing is driven by charge and temperature together, so shaded or sheltered positions have real value for long-dwell units. There are also documented low-temperature limits below which extended exposure risks irreversible damage.
Keep charging positions accessibleA unit that needs three vehicles moved to reach a charger will not be charged on time. Charging access is a slotting decision, and it should influence where long-dwell units are parked in the first place.
Log every charging event against the VINSo the declared battery condition has evidence behind it, and so a unit's charge history exists if a dispute or a warranty question arises later. An undocumented top-up is work you performed and cannot demonstrate.
What the Record Has to Hold
Seven fields per VIN. Together they answer every question above without anyone walking the yard.
Charge at gate-in, and at each re-checkWith timestamps, so drift is visible as a trend rather than as a surprise.
Battery chemistryCaptured at intake, because it determines which storage policy applies.
Intended movement, mode and dateWhich sets the target window — air, sea or continued storage.
Campaign and recall statusBecause an open recall refuses the booking outright on most carriers.
Fault and warning lamp statusChecked during dwell rather than at loading, since active lamps block acceptance.
Charging events performedSupporting the declared battery condition and the unit's history.
Position and dwellIncluding whether the unit is somewhere it can actually be reached and charged.
Bring your current BEV inventory and we'll show you the exposure in twenty minutes
On a working session we'll take your battery-electric units and their planned movements into Fleet Rabbit, flag those sitting outside the window their next mode requires, identify those drifting toward a protective shutdown, and separate the ones blocked by an open campaign or an active fault from the ones blocked by charge. You keep the analysis either way — and for most compounds it is the first time charge state, campaign status and dispatch plan have been in the same view.
Frequently Asked Questions
What state of charge should our compound hold units at?
It depends on what happens next, which is why a single figure does not work. For air freight the limit is 30% or below and it is enforced. Most sea and RoRo carriers require the traction battery between roughly 30 and 50%. For storage itself, the least calendar ageing occurs around 50 to 60%, with 40 to 60% commonly cited for anything beyond a couple of weeks. Drive the target from the intended movement and its date rather than setting one rule at the gate.
What actually changed in January 2026?
Two things at once. Battery-powered vehicles were reclassified under new UN numbers — lithium-ion vehicles now falling under UN 3556, with separate designations for lithium-metal and sodium-ion — bringing them fully into the dangerous goods framework. Separately, the air charge limit moved from recommendation to mandatory with standardised enforcement, and verification is now physical during inspection. Guidance is explicit that shipments which succeeded in 2025 can be rejected in 2026 with identical packaging and paperwork.
Can an open recall really stop a shipment?
Yes. Most carriers refuse the booking where a recall is outstanding, requiring the repair to be completed first. That makes campaign status a shipping gate rather than a quality workflow item — a unit with an open campaign is not simply awaiting rectification, it is ineligible to move. Alongside it, carriers require no active warning lights and a declared battery condition, so all three should be screened before a slot is taken rather than at the ramp.
Why does charge fall while the vehicle is parked?
Two mechanisms. These vehicles maintain cellular connections and run background software while parked, unlike a vehicle with a simple key-off state, so there is a continuous draw by design. Separately, cells self-discharge through internal side reactions whose rate rises with temperature — a common rule of thumb has many of those reactions roughly doubling for every ten degrees above room temperature. Both continue regardless of whether anyone touches the vehicle.
What happens if a unit goes flat in the compound?
It can become considerably more than a charging job. If the high-voltage pack drops too low the battery management system may enter a protective shutdown, and recovering from that state can require a dealer visit — with permanent capacity loss possible in extreme cases. A vehicle already sitting at low charge can drift into over-discharge through self-discharge alone. Set a floor alert well above the shipping minimum, because the lower boundary protects the asset rather than the schedule.
Does the same storage rule apply to every EV?
No, and this catches out compounds holding mixed inventory. The mid-charge storage guidance reflects the widely used lithium-ion chemistries. Lithium iron phosphate behaves differently — more stable at high charge and without the same degradation penalty at the top of its range, with at least one manufacturer recommending regular charging to full and even charging to full before storage. That makes battery chemistry an operational field to capture at intake rather than a specification detail.
Where should we start?
By putting charge state, chemistry, campaign status and intended movement on the same record for every battery-electric unit in the compound. That combination is what lets you ask the only question that matters — which units are outside the window their next movement requires, and which are heading there. Book a session with your current BEV inventory and we'll produce that view with you.
Charge Is a Moving Number, Not a Field
Set the target from the dispatch plan, track the drift rather than the arrival figure, alert on the floor well before the danger zone, screen recalls and warning lamps before the slot is booked — and hold chemistry against the VIN, because the storage rule is not the same for every unit in the yard.
