What ships on every Joulepoint charger

14 admin capabilities. All built in.

Every Joulepoint charger ships with a production-grade admin and kiosk HMI — no separate UI subscription, no third-party vendor portal. Below is what your operators get out of the box.

Operator overview

Single-pane controller / CSMS / PLC / network health, plus a live operations snapshot — the first thing your field engineer sees on every visit.

Per-connector workspace

Live electrical values for every gun, session and auth state, planner context, vehicle demand — plus stop / clear-fault controls without leaving the kiosk.

Session analytics

Active and historical sessions with energy, power, duration, and per-row deep links. Built in, not a separate dashboard product.

Site-aware power planner

Hot-reloadable site limit, OCPP SmartCharging integration, group power cap per PLC chain, cross-PLC borrowing toggle — editable without a controller restart.

Fault Center

Connector and PLC fault history with active vs resolved separation. No more digging through 30 MB log files to find what tripped the bay.

Live Configuration Editor

Edit modules, OCPP, RFID, planner, PLC transport, authorization — and save without restarting the controller. Field-tunable in minutes.

White-label HMI

Upload your logo and support phone. The kiosk and admin views rebrand immediately. OEMs ship branded UI on day one.

Network workspace

Wi-Fi SSID scan + on-screen connect, wired primary device control, gateway and address visibility, plus a one-click Capture Diagnostic for field handoff.

Remote Support Tunnel (Tailscale)

Optional encrypted peer-to-peer mesh tunnel. The charger works fully without it — leave it off when you don't need remote access. No port forwarding, no static IP, no cellular VPN bill.

PLC ops

Per-chain health for every PLC chain in the cabinet — separate from controller health so you can isolate where a fault really lives.

Logs

Time-windowed runtime log access from the UI. Pair with Capture Diagnostic to ship an evidence bundle to engineering without SSH.

Maintenance workspace

Health checklist plus operator-grade actions: Refresh Health, Recompute Planner, Restart Controller. No full reboot, no field engineer escalation.

Per-device licence

Activation codes are minted against the Linux device fingerprint of that specific controller. Codes for any other unit are rejected — anti-counterfeit and refurb protection without DRM friction.

Multi-vendor module support

Driver-based abstraction over power modules. Qualify two or three vendors and source whichever wins each batch — no firmware change.

Live walkthroughs and screen recordings are available under NDA — talk to our sales engineering team.

Problems we solve · competitive advantage

Why CPOs and EVSE OEMs win with Joulepoint chargers.

Most charger problems aren't about the power electronics — they're about the controller, the HMI, the remote access, the licensing, and the lock-in. We rebuilt that whole layer.

Truck-roll for every config change

Industry default — every parameter tweak means a field visit

Hot-reloadable Config Editor + Remote Tunnel: change driver, modules, OCPP profile, RFID, planner from anywhere, no controller restart.

Expensive cellular VPN for remote diagnostics

Most CPOs pay $30–80 per charger per month for a managed APN + remote SSH

Built-in Tailscale mesh — peer-to-peer, encrypted, no port forwarding, no static IP. Toggle on only when support is needed.

Power-module vendor lock-in

Most charger controllers are hard-wired to one module brand

Driver-based module abstraction (we ship LAN GenericKM2 BLN and others). Source the cheapest qualified module without rewriting firmware.

No anti-piracy on the controller

Refurbed and grey-market chargers eat OEM margin

Per-device hardware-bound licence — activation codes are minted from a Linux device fingerprint; codes for any other unit are rejected.

Custom HMI takes 6–12 months to build

Most OEMs ship a vendor HMI on top of someone else's controller

Production-grade admin HMI with white-label logo + support phone upload. OEMs ship a branded UI on day one.

Multi-connector power sharing is a mess

Static splits waste headroom; live sharing usually needs a separate dispatcher box

Built-in site-aware planner: site limit + OCPP SmartCharging + group cap + cross-PLC borrowing — hot-editable from the UI.

Field staff can't recover faults without the OEM

Operators end up calling the OEM for every fault, every time

Fault Center, Refresh Health, Recompute Planner, Restart Controller — operator-grade actions in the UI, no SSH required.

CSMS lock-in by the controller vendor

Many OEM controllers only talk to that OEM's CSMS

Native OCPP 1.6J / 2.0.1 — point Charge-Point ID + CSMS URL at any CSMS (ours, AmpEco, Driivz, Monta, your own). Change it from the live config without firmware.

What this actually saves you

Concrete cost arguments by buyer persona. Numbers are mid-market estimates from public CPO operating benchmarks and our own deployments in India and Europe.

For Charge-Point Operators

CPO
  • Cut remote-access spend

    Tailscale's free / starter plans replace the typical cellular APN + VPN concentrator. For a 500-charger network this is $15k–$40k/year of OPEX gone, with stronger encryption than most managed APNs.

    ~$30–80 / charger / month saved

  • Kill truck-rolls for config

    Every site visit costs ₹3,000–8,000 in fuel + engineer time in India, $100–400 in the EU/US. Hot-reload + remote tunnel removes 60–80% of those visits — the ones that exist today only to change a parameter or restart a process.

    ~60–80% of config-driven truck-rolls eliminated

  • Stop paying for a third-party HMI

    Our kiosk + admin is included. No separate UI subscription, no per-charger licence on top of the controller, no $5–15/month-per-charger HMI vendor.

    $60–180 / charger / year saved

For EVSE Manufacturers / OEMs

OEM
  • Ship a branded controller on day one

    Upload your logo + support phone, mint per-device licence codes from a fingerprint. Skip the 6–12 month effort of building your own admin HMI and licensing pipeline.

    ~6–12 months engineering avoided

  • Protect aftermarket revenue

    Each activation code is bound to a specific Linux device fingerprint. Refurbished units can't be cloned, grey-market boxes can't bypass spare-parts revenue.

    Refurb / grey-market arbitrage removed

  • Source modules competitively

    The module abstraction lets you qualify two or three power-module vendors and quote whichever wins each batch — without firmware changes. Direct margin lift on every cabinet.

Tariff-aware off-peak charging via Matter Energy Management Cluster.

Local control over Thread / Wi-Fi — no Joulepoint cloud round-trip required.

Offline-first charging

Smart even when the network is not.

Indian deployments live with patchy 4G and intermittent backhaul. Joulepoint chargers don't stop charging when the network does — they keep the session alive and resync billing data when connectivity returns.

Network dropsCSMS unreachableLocal authoriseRFID / PnC cacheCharge + signOCMF meter valuesNetwork returnsResync CDRs

Authorise & start without network

Local RFID whitelist + cached PnC certificates keep sessions starting even when the upstream CSMS is unreachable.

OCMF-signed offline buffer

Meter values are cryptographically signed at the charger. Billing-grade evidence preserved across hours or days of disconnect.

Tamper-evident ledger

Append-only local store with monotonically-increasing sequence numbers. If anything is dropped or replayed, the CSMS detects it.

Idempotent resync

When the network returns, sessions and CDRs replay automatically. No duplicate billing, no manual reconciliation.

A real-world example

At an Indian state-transport depot, the 4G backhaul drops at peak load. Joulepoint chargers continue authorising depot buses via the local RFID list, deliver power, sign every meter value with the OCMF private key, and replay all CDRs to the CSMS once the link recovers — typically within minutes, but tested up to 48 hours.

Built for Rollouts of Any Scale

Joulepoint chargers share a common electronics platform, giving you consistent diagnostics, spare part logistics, and firmware upgrades across AC and DC product lines. All enclosures are IP55/IK10 rated with conformal-coated PCBs to withstand heat, humidity, and coastal environments.

Smart load orchestration

Dynamic load balancing, phase rotation, and peak shaving policies run locally with seamless fall back to CSMS control.

Serviceability

Hot-swappable power modules, rear access for technicians, and modular cable sets keep downtime under 30 minutes.

Security & compliance

Secure boot, TPM-backed certificates, and AIS-138 / CE compliance keep your sites audit ready.

Driver experience

15-inch outdoor displays, accessible reach height, and multi-language UI deliver a consistent brand experience.
