Manufacturing · EV Charger Manufacturer Management Software

One system for charger models, module lots, end-of-line tests and field returns.

Each charger serial holds the rectifier module lot inside it, the control board revision, the firmware build flashed and the RCD trip, insulation and meter readings taken on the bench. Engineering keeps the option lists. Stores books modules by lot, and the line marks wiring, torque and closing. Support opens the same serial when a unit comes back with a tripped contactor.

  • Models, connector options and parts lists loaded the way you build
  • Open orders, stock and past serials brought across
  • Test limits and firmware rules set with your own engineering and quality staff

Makers of wallboxes and charger cabinets keep model and option lists, module and board lots, firmware builds and end-of-line tests in one record per serial. Returns are logged on that same record. Support sees what sits inside a charger before unscrewing the gland plate.

Where it breaks today

What goes wrong before the software.

Firmware builds are mixed within a batch

A flashing station updated mid-run leaves some units on the old build. Nobody can say which without plugging a laptop into each OCPP gateway. Then the wrong build ships to a fleet customer, and the depot calls.

Module faults cannot be narrowed to a lot

A rectifier module that fails early was bought in several lots. The shop record shows only the charger serial, so every unit becomes a suspect. The whole batch earns a site visit, with a technician and a spare module in the van.

Test files live on the bench computer

Residual current, insulation resistance, meter reference and link checks are saved as CSV files on one bench PC. The nameplate and the delivery note are typed separately, and they can disagree with the result.

Option combinations create odd builds

Connector type (socket outlet or tethered cable), meter, touchscreen, RFID reader and payment terminal combine in many ways. A special order gets a parts list rebuilt by hand, and the odd build is forgotten next time.

Cable assemblies hold up final close

Tethered cable and connector assemblies arrive from a subcontractor in small lots. Chargers sit finished but for the lead. The gap shows only when a planner walks the floor.

Returned chargers arrive without a record

A unit returns from a customer car park with only its serial. The service team opens the enclosure to read the board, module and firmware, then phones engineering to ask what changed since dispatch.

How it runs

How the work flows through it, step by step.

  1. 1

    Order

    A customer orders chargers by model, power rating, connector, cable length and options. Special requests, such as a sunshade or a pedestal mount, are noted on the order.

  2. 2

    Parts plan

    The model’s parts list is exploded against stock. Modules, boards, energy meters and cable assemblies are reserved or ordered, and a shortage shows before the build is released.

  3. 3

    Assembly

    Units move through enclosure preparation, busbar and contactor wiring, module fitting and closing. The line operator marks each step.

  4. 4

    Firmware and end-of-line test

    Each firmware build is logged with the unit. RCD trip current, insulation resistance, meter accuracy and communication readings are taken at the end of the line and held with it.

  5. 5

    Label and dispatch

    Rating plates and serial labels print from the record. Delivery notes list serials together with the firmware version.

  6. 6

    Service

    Faults and returns are logged against the serial. The record shows board revision, module lot and firmware, so repair starts informed.

Modules

What is inside.

Every module can be switched on, left out or changed to match how your team already works.

Charger model catalogue

Hold each power rating, connector, meter and enclosure with its own parts list, from a seven kilowatt wallbox to a multi-module cabinet with liquid cooling.

Option rules

Combine optional parts such as touchscreens, RFID readers, payment terminals and cable lengths into one parts list per order.

Power module and board lots

Receive rectifier modules, control boards and energy meters by lot, with the supplier reference and the receiving inspection result.

Cable assembly orders

Order cable and connector assemblies from a subcontractor, with quantity and due date, and check each lot against the drawing on return.

Assembly line jobs

Follow units through wiring, module fitting and closing with operator marks, so a planner sees exactly which bay a charger waits in.

Firmware loading record

Store the firmware version flashed to each unit and flag a mismatch within a batch before the unit leaves the bench.

End-of-line test entry

Save RCD trip current, insulation resistance, meter accuracy and communication results to the unit serial.

Serial plates and labels

Print rating plates and serial labels from the stored unit record.

Distributor and project orders

Take orders from distributors, installers and fleet depots, and allocate finished units to them.

Commissioning notes

Keep the installation handover notes, earth loop reading and site address with the unit’s serial.

Returns and fault log

Log faults against the unit’s lots and firmware so patterns appear by module revision or board.

Solutions inside

The business modules it is built from.

Each one is also available on its own, or inside a system built for you.

  • Product Management

    Each power rating, connector and enclosure is held as a model with its own specification, so an order is entered by choosing, not typing.

  • Bill of Materials

    Optional touchscreens, RFID readers and cable lengths combine with the base model to give the exact parts list for one customer’s order.

  • Batch and Serial Tracking

    Modules, control boards and meters are received by lot, so a suspect lot can be traced to the serials that carry it.

  • Job Work Management

    Cable and connector assemblies go out as subcontract orders with quantity and due date, then get checked against what comes back.

  • Work Order Management

    Each charger moves through wiring, module fitting and closing, with the operator marking steps and the planner seeing where units wait.

  • Quality Control

    RCD, insulation, meter and communication results are saved per serial against agreed limits, and a failed unit is held back.

  • Barcodes and Labels

    Rating plates and serial labels are printed from the unit record so the plate, the test file and the delivery note agree.

  • Ticket Management

    A fault raised by a customer opens a ticket on the serial, showing its lots and firmware, and repairs are logged to the same unit.

Services

How we would put it in.

Setup, data migration, integrations and anything built on top.

Who uses it

One system, each person sees their part.

For production planners

Release builds against orders and see which units wait on modules or leads.

For assembly operators

See the jobs for the shift and mark each unit as wired, fitted and closed.

For test engineers

Record the end-of-line readings and the firmware flashed, and hold back failed units.

For the stores

Book power modules, boards and cable assemblies in by lot, then issue them to the unit being built.

For service and support staff

Open any serial to see its lots and firmware, then log faults and returns.

Reports

The numbers the owner asks for.

  • Units by model and stage
  • End-of-line failures by reading type
  • Firmware version by shipped serial
  • Module and board lots by failure count
  • Cable assemblies due and late
  • Returns by lot and fault
Good fit

Who this is built for.

  • Makers of AC wallboxes for homes and workplaces
  • Builders of DC fast charger cabinets
  • Producers of portable and bidirectional chargers
  • Contract assemblers building chargers for brands
  • Firms selling through installers and fleet operators
Honest answer

When it is not the right choice.

  • An installer who only mounts and commissions chargers needs a field service system.
  • A network operator running charging sites needs a charge point back office.

Common questions

Questions owners ask before a demo.

Can it tell us which firmware each shipped charger carries?

Yes. The flashing step stores the version against the serial, and a report lists shipped serials by build. A change within a batch is flagged at the bench before the enclosure is closed.

How do we find every charger with a suspect module lot?

Search by module lot to list the serials that used it, with their customers and ship dates. Service can then plan the contact, starting with the units nearest failure.

Does it handle both AC wallboxes and DC cabinets?

Yes. Each model has its own parts list and build steps, so a cabinet with several rectifier modules, a dispenser and cooling parts is held separately from a simple wallbox.

Which end-of-line readings can be stored?

Residual current trip, insulation resistance, meter accuracy, communication checks and any reading your test bench produces. Your engineers decide the limits.

Can cables from a subcontractor be tracked?

Yes. A cable assembly order states quantity and due date, and the incoming check is logged against it. A unit waiting for its lead shows against that order, so nobody hunts the floor.

Does it replace our charging back office?

No. It records the factory and service side of each unit. Live charging sessions, tariffs and network control stay in the back office system you already use for them.

How are plates and labels produced?

Rating plates and serial labels are printed from the stored record on your label printer. Layouts follow your own template.

How are options like screens priced?

Option parts carry their own rates and appear in the quotation lines for that charger model. Special requests are quoted line by line.

Can past serials be imported?

Yes. Past serials and their firmware and test results can be loaded from spreadsheets. The team checks a sample before go-live.

How is a demonstration organised?

You choose one model and one test sheet, and the demo is built around them. A written proposal covers users, modules and setup.
