Technical guides about OCPP, CPO operations, smart charging and e-mobility.
A clear guide to EV charging connector types worldwide: Type 1, Type 2, CCS1, CCS2, CHAdeMO, NACS (SAE J3400), GB/T and MCS. Where each is used, AC or DC, typical power and what operators should install.
Read more →OCPP and OCPI sound alike but solve different problems. OCPP connects chargers to their management system; OCPI connects charging companies to each other for roaming. See the differences, how they combine in one session and what your platform needs.
Read more →OCPI (Open Charge Point Interface) lets charging networks and e-mobility providers share locations, tariffs, sessions and billing data. Learn how it works, its main modules, versions and how to get started with OCPI roaming.
Read more →What is the difference between a charge point operator (CPO) and an e-mobility service provider (eMSP)? How each earns money, how they work together through roaming, and which role suits your business.
Read more →Location decides most of a charging site's success. Learn the criteria that matter, from traffic and dwell time to grid capacity and lease terms, plus a simple scoring model to compare candidate sites objectively.
Read more →Utilisation is the number that decides whether a charging site pays back. Here are 12 practical tactics to sell more kWh per charger: visibility, reliability, open access, pricing, roaming, fleet deals and data-driven site management.
Read more →Idle fees charge drivers who stay plugged in after charging has finished. Learn when to use them, how to set grace periods and rates, how to detect idle time with OCPP and how to communicate the rules fairly.
Read more →How to set EV charging prices that cover costs, attract drivers and stay compliant: cost-plus pricing, market benchmarking, time-of-day tariffs, idle fees, membership plans and the mistakes to avoid.
Read more →A practical template for an EV charging station business plan: market analysis, site strategy, revenue model, cost structure, financial projections, risks and the operating setup investors and lenders expect to see.
Read more →Whether an EV charging business makes money depends on a few numbers: utilisation, margin per kWh, capital cost and uptime. This guide shows how to calculate revenue, costs, payback and ROI with a worked example.
Read more →A realistic breakdown of EV charging station costs in 2026: AC and DC hardware prices, installation, grid connection, software fees and maintenance, with example budgets for three common projects.
Read more →Practical OCPP guide to V2G and V2X with OCPP 2.1, covering protocol versions, field behaviour, security, troubleshooting, logs and operator checks.
