What the plan ends with

Four Figures Battery Pack Line Capacity Planning Settles

Battery pack line capacity planning ends with these four, and every later decision on the project hangs off them. They are quoted together or not at all.

GWh / yr

Annual output

The figure promised to your own customer or board. The rest of the plan is solved backwards from it.
PPM

Takt at the loading point

The rate the line has to hold. Counted as cells entering the module segment, not packs leaving the end.
L × W × H

Footprint

Length, width and clear height. Decides whether the building you already have can take the line at all.
By segment

Headcount

Cell handling, module welding and pack assembly counted apart. The figure that repeats every year the line runs.

The four constrain each other

That is why they are settled at the selection stage, before a configuration is fixed. A target that needs 12 to 15 PPM needs a bay 20 m wide; a bay 9 m wide sets a ceiling on the tier that no budget lifts.

Working them out in the wrong order is how a plant ends up with a line it cannot fit, or a rate it cannot staff.

The two that move the answer most

  • 04 · Shift pattern and working days. Sets the hours term. Moving from one shift to two changes the answer more than any equipment choice on this page does.
  • 05 · Module and pack configuration. Closes the calculation, because annual output is energy per unit multiplied by units per year.

What PPM counts, and where

PPMPieces per minute, counted as one cell entering the module segment — not packs per minute and not modules per minute. is a loading rate at a physical point, not an average across a shift. Every cell is scanned, tested and sorted at the cell testing and sorting station before anything downstream sees it, so the count already exists inside the machine and can be read off it during acceptance.

Substituting your own figures

A 280 Ah cell moves the energy term. A different series count moves the module and pack figures but not the cell rate. Two shifts move the hours term. That substitution is done for you, with the counting point named, and the same expression is run again in the pre-assembly bay before the line ships.

The 0.85, settled early

Shift Pattern And Uptime

The 300 days at eight hours is a basis, not a limit — and the 0.85 is the term worth agreeing before anything is quoted.

PLANT

Time availability

Changeovers, breaks, handovers and maintenance windows — decided by your plant as much as by machine faults. Shared.
PLANT

Performance availability

Whether the line is actually fed at rate. A plant with clean handovers and a stable cell supply runs above 0.85. Shared.
OURS

First-pass yield

Good units divided by units started. Ours aloneEquipment-caused yield of 99% or better, human factors excluded in writing — the one term of the three we sign for. at 99% or better.

Shifts move the answer further than equipment

Two shifts change the hours term from eight to sixteen, and the annual output with it. Most plants that reach the upper half of a tier's range do so on shifts rather than on hardware, and a plant running more working days than the 300 quoted lands above the range on identical equipment.

Three builds, one station set

Three Tiers, Five Planning Figures

Takt is not what separates the three builds on offer. The automation level is — and the floor area, clear height and installed power that follow from it. Those are also the figures your building has to accept.

Planning figures for the three battery pack line tiers

Installed power 200 kWLightest on supply of the three ≤250 kWHigher draw on a smaller floor 300 kWIn the building, not in a plan

Read the table by column, not by row

BLP-P8S is the economy build: more operators, fewer automated positions, the lowest installed power of the three, and it wants a building with length and width to spare. BLP-P8 is the standard build and the only one that fits under 3.5 m of clear height, which makes it the tier for older halls with a low beam line.

BLP-P15 is the high-automation build, and its distinguishing figure is width rather than length. All three come off the same station designs and the same acceptance criteria; what changes is how many positions are machines.

Floor traded for kilowatts

Footprint Against Installed Power

Two figures in that table run against the intuition that a cheaper line is a smaller one: the economy build is 56 × 10 m against 55 × 9 m, and draws 200 kW against 250 kW or less. It is the larger line and the quieter one at once.

BLP-P8S — 56 × 10 m · 200 kW 10 m BLP-P8 — 55 × 9 m · ≤250 kW 9 m BLP-P15 — 54 × 20 m · 300 kW same line route automation alongside it 20 m

Drawn to one scale. Length moves by 2 m across the three tiers; width doubles.

A manual position

Needs an aisle behind it, a working face in front of it and room to move between the two. It draws almost nothing.

An automated position

Needs the machine envelope, its guarding and its installed power — and no aisle at all.

Bay width rules a tier out

Trading people for machines trades floor area for kilowatts, in both directions. A hall long enough for all three can still be too narrow for one of them.

Machine positions buy back aisle and spend installed power.

Headcount By Line Segment

Given by segment rather than as a line total, because the segments do not move together when automation is added.

Cell handling44
Module welding43
Pack assembly12–1412–14

Quoted for the tier you are offered, alongside the station list with an automation label on every station.

Automation buys one person, in one segment

Set the two columns side by side and the whole effect of automation on this line is one person, in module welding. Cell handling is 4 in both, because unloading, scanning, sorting and gap refilling are already machine work at every tier — the operators feed trays and clear rejects.

Pack assembly is 12 to 14 in both, and that is the figure worth reading twice.

Countable on the floorThe line is stood up in our pre-assembly bay in its shipping configuration, so your engineers can walk it counting positions against both documents
AUTO

One automated station in the pack segment

Of the 15 pack stations, gluing is the automated one — and that is why the headcount does not fall.
MANUAL

Hand work at every tier on offer

Enclosure and cooling plate cleaning, module insertion and fixing, busbar and BMS installation, MSD and connector fitting, harness dressing, lid tightening and front panel assembly.
SEMI-AUTO

Three numbers and one habit

Your Building In Battery Pack Line Capacity Planning

Length and width decide whether the line runs straight or has to be folded, and folding costs transfer distance rather than capability. Clear height decides which tiers are available at all, since two of the three want 4 m.

Measure to the lowest obstruction

Ceiling services — cable tray, sprinkler pipework, ducting and crane rail — commonly occupy 300 to 500 mm across an industrial hall. A building quoted at 4 m to the beam can leave 3.6 m of usable height along the line route.

Send a floor plan with the low points marked and the layout comes back drawn around them, rather than drawn to a ceiling height that only exists between the obstructions.

3.5 m or 4 mTwo tiers need 4 m of clear height; one fits under 3.5 m. Which of those your hall really offers is settled with a tape measure, not a drawing

The first fork

Economy Or Standard Build

Decided on three things: the floor you have, the supply you have, and how many operators you can staff. It is not decided on rate.

BLP-P8S · 200 kW · 56 × 10 × 4 m

Take the economy build

When the building has length and width to spare and the electrical supply is the tight constraint. At 200 kW it is the lightest of the three on installed power, and it puts the work into positions people hold rather than into machines that have to be fed.
Economy build with operator positions along the module segment
BLP-P8 · ≤250 kW · 55 × 9 × 3.5 m

Take the standard build

When the hall is the constraint. It is the only one of the three that fits under 3.5 m of clear height and the narrowest at 9 m, which makes it the answer in older buildings with a low beam line or a crane rail in the way.
Standard build drawn narrow for a hall with a low beam line
Same criteria either wayBoth hold equipment-caused yield of 99% or better and are signed off against the same written criteria. What is being chosen is the split between machine positions and people positions — and the floor and power that split produces

Three conditions, together

The Case For High Automation

The high-automation build earns its place when all three hold at once. Two out of three is a reason to stay on the standard build.

1 – 2 GWh

Output beyond one line

A target above what a single economy or standard line reaches on the shifts you can actually staff. At 12 to 15 PPM this build is quoted at 1 to 2 GWh a year on the blueprint configuration.
20 m × 4 m

Bay width and clear height

The condition that decides the answer earliest, because a 20 m bay width is not something a layout revision recovers. Length is rarely the problem; width is.
300 kW

Installed supply at the line

Present in the building rather than in a plan. Three-phase five-wire 380 V ±5% at 50 Hz, like the other two tiers.
Pack built on the high-automation tier at 12 to 15 PPM
The difference shows in module welding, which runs on 3 people rather than 4, and in the consistency that comes from more of the flow being machine-paced.
Sorting station feeding the high-automation tier at rate

Pack assembly stays at 12 to 14 people. Weigh the tier on those terms rather than on an expectation that a faster line is a leaner one.

Four routes, in cost order

Growing Past The First Line

Expansion has four routes and they are not equally expensive. Taken in order of what they cost you:

01 · NO CAPITAL

Add a shift

The hours term in the calculation doubles, the line is untouched, and nothing in the building changes.
02 · DISCIPLINE

Raise uptime above 0.85

Changeover discipline, feeding and handover rather than hardware. Worth doing before any capital route, because it multiplies everything after it.
03 · TOOLING

Change the cell or configuration

Inside the printed envelopes this is a tooling and recipe change rather than a new line, and the fixtures are quoted against your part.
04 · A SECOND LINE

Build the next one

Needs its own length, width, clear height, installed power, and floor loading of 800 kg per square metre or better.

Three margins keep routes three and four open

  • Clear height. Fixed the day the building is chosen, and the one margin no revision recovers.
  • Bay width. A hall filled to its width by the first line closes the cheapest version of the fourth route.
  • Spare installed power. Cheaper to specify once than to bring in again later.

All three are marked on the layout drawing at the quotation stage — so the second line is a decision, not a discovery.

100–220 mmCells 100 to 220 mm wide, 100 to 220 mm high and 20 to 80 mm thick; modules 400 to 1200 by 100 to 300 by 100 to 250 mm. Station by station on the cell compatibility and changeover page
Changeover fixtures that keep route three inside a tooling change
Outside those envelopes it stops being a changeover — which is why the edges are printed rather than described as flexible.

What comes back

Battery Pack Line Capacity Planning Deliverables

Four things come back within 24 hours, and the takt, the footprint, the power and the people are all four in that first reply.

  • Tier recommendation with the reason attached. Named against your bay, your supply and the operators you can staff — not against rate alone.
  • The output calculation worked on your figures. Your cell, your series count, your shift pattern, with the counting point named.
  • A layout drawn against your floor plan. To your column grid and clear height, with the three expansion margins marked.
  • The headcount table by segment. With the station list and an automation label on every station.

Then the line is stood up before it ships

After the order it is assembled and powered up in our own hall before anything is crated. Three bays in the 6,000 m² assembly hall are kept for full-line pre-assembly, so it stands in its shipping configuration and runs there first. Two weeks' notice with your cell drawings and target takt, and the bay is set up in your configuration for the visit. If travel is not possible, the same criteria are run on video.

Behind it: 26 engineers, 40+ line segments delivered into 12 countries, wear parts within 48 hours — on the about page.
