Two tracks, one place: go hands-on with the AmpNexus platform in Engineering, or follow product highlights and market thinking in Insights.
Engineering
You can't point a thousand real chargers at a test environment — so how do you test the software that runs them? Inside our approach: OCPP simulation, per-release quality gates, twice-weekly load tests, and publishing the results.
Charge point events need to reach billing, CRM and ops tooling in real time. A practical comparison of webhooks and SSE for charging telemetry — when to use each, and the delivery guarantees that actually matter.
Charger downtime is rarely one dramatic failure. It's connectivity drops, stuck firmware, silent faults and zombie sessions. A field guide to the real causes, and the monitoring that catches each one.
Charging networks are payment systems, IoT fleets and grid-connected infrastructure at once. A practical tour of the attack surface — device, transport, platform and process — and the controls that actually matter.
Most charging networks will run OCPP 1.6 and 2.x side by side for years. Here's a practical migration strategy that doesn't bet your uptime on a single cutover weekend.
Councils with district partners, operators with franchisees, white-label networks under one roof — multi-tenancy is what makes them safe. What tenant isolation actually means, and how to test whether a platform really has it.
Repointing a live charger fleet to a new backend is routine when planned well — and chaos when it isn't. A migration playbook: discovery, cohorts, the cutover moment, and the data you must not leave behind.
Most sites can't give every charger full power at once — and they don't need to. How static and dynamic load management work, what OCPP charging profiles actually do, and the failure modes to design for.
The gap between 'installed' and 'earning' is where charging projects lose weeks. A commissioning playbook: pre-staging, guided installer flows, acceptance criteria and the handover evidence that prevents disputes.
One talks to chargers, the other talks to the market. A working map of the charging protocol landscape — OCPP, OCPI, OpenADR and friends — and what each one means for your architecture.
Every disputed charging invoice traces back to a data problem: missing meter values, zombie sessions, double-counted events. The engineering discipline that makes billing boring — in the best way.
Plug in, walk away, get billed correctly — no app, no card. How Plug & Charge actually works, what it demands from chargers and backends, and a realistic view of where it fits alongside RFID and contactless.
How AmpNexus publishes, targets, stages, observes, and safely pauses firmware updates across a fleet of EV charge points—complete with screenshot callouts and API examples.
Insights
Every charger failure found by a driver costs more than the repair: lost sessions, SLA penalties, wasted engineer visits and eroded trust. Here's how predictive maintenance changes the economics of running a charging network.
Beyond the vanity dashboard: the KPIs that actually predict whether a charging network is healthy, growing and fundable — and the traps hiding inside each one.
Drivers remember the name on the app, not the company running the backend. What white-label really covers in EV charging, why it matters commercially, and the questions that separate a reskin from the real thing.
Procurement teams evaluate charging platforms without an easy way to separate glossy claims from operational reality. These twelve questions — and the answers to listen for — do exactly that.
Local authorities are becoming charging operators — often without operator experience in-house. What separates the schemes residents praise from the ones that make local news, and how to procure for the difference.
CPMS, CSMS, backend, platform — the industry uses the terms loosely. Here's what a charge point management system actually does, what separates a good one from a basic one, and how to evaluate the options.
Reliability targets, contactless payment, price transparency, open data and a 24/7 helpline — what the UK's public charging rules actually require, and what they mean for the software running your network.
Depot charging succeeds or fails on questions the hardware brochure never mentions: departure readiness, grid budgets, driver behaviour and data for the CFO. A checklist for fleet operators going electric.
A charging network is a large, controllable electrical load — and the energy system increasingly pays for controllable. What grid flexibility means for operators, what's real today versus speculative, and how to become flexibility-ready.
Hardware shortlists get all the attention, but the platform decision determines what your chargers can ever become. Why software-first is the right order, and the hardware questions that actually matter.
Price too high and utilisation dies; too low and every session loses money; too cleverly and drivers stop trusting you. A practical framework for public charging tariffs — structures, idle fees, and the transparency that regulation now demands.
Two chargers by reception worked fine — until thirty staff bought EVs. Why workplace charging breaks at scale, and the access, fairness and reporting decisions that make it work as real infrastructure.
