What We Do
Four practices, one engineering team
Deep enough to lead in EV charging and AI, broad enough to run your core enterprise systems — with the same engineers accountable from architecture to production.
EV Charging & CSMS
OCPP 1.6 & 2.0 certified charge point management systems, built for operators who can't afford downtime.
- OCPP 1.6 & 2.0 Implementation
- OCPI Roaming & Interoperability
- Smart Charging & Load Management
- Real-Time Monitoring & Analytics
AI Enablement & Solutions
Practical AI adoption for real businesses — from opportunity assessment to production deployment.
- AI Opportunity Assessment
- LLM & Agent Integration
- Process Automation
- Data-Driven Decision Support
Cybersecurity
Fixed-price security for small and mid-sized businesses — from emergency patching to Cyber Essentials.
- Small Business Security Checks
- PHP2Shell & Critical Patch Response
- AWS Security Health Checks
- Cyber Essentials Readiness (UK)
Enterprise Software
Custom, mission-critical applications and cloud infrastructure engineered to scale.
- Custom Enterprise Applications
- Native iOS & Android Development
- AWS Cloud Architecture & DevOps
- Legacy System Modernization
Open standards
EV Charging Platforms
Charging software built for networks that can't go dark
We build and operate the CSMS platforms behind live charging networks, including REDE Charging — from the protocol layer up to billing, roaming and operator dashboards.
- CSMS cores that run mixed 1.6-J and 2.0.1 fleets side by side
- OCPI roaming on both the CPO and eMSP side, including CDR reconciliation
- Smart charging that keeps sites inside their electrical capacity
- RFID, app and contactless payments built for unattended sites
Why HashTech
Software is a long game. Here's what two decades of playing it has taught us.
23+ Years in Business
Founded in 2001. Built for durability and long-term partnerships, not hype cycles.
Deep Domain Expertise
From OCPP-certified charging platforms to Fortune 500 enterprise systems — specialized, not generic.
AWS-Native Delivery
Cloud architecture, security, and DevOps built in from day one, not bolted on later.
Trusted by Industry Leaders
Long-standing relationships with organizations like TCS, ISRO, and Medtronic.
Insights
Field notes from the engineers building it
OCPP 1.6-J Tutorial
A hands-on walkthrough of OCPP 1.6-J, from the first WebSocket connection to smart charging and security profiles, with real message examples.
Start the seriesOCPP 2.0.1 Tutorial
How OCPP 2.0.1 works in practice: the device model, the transaction event model, ISO 15118, security, and migrating from 1.6.
Start the seriesOCPI 2.2.1 Tutorial
Building EV roaming with OCPI 2.2.1: credentials, locations, tokens, sessions, CDRs, tariffs and commands, from both the CPO and eMSP side.
Start the seriesPHP2Shell (CVE-2026-109618, CVE-2026-109619): What It Is and How to Patch Every Server
A practical PHP2Shell guide: affected and fixed PHP versions, how to find every PHP runtime, patching per platform, workarounds and compromise checks.
EV Charging Protocols Explained: OCPP, OCPI, OICP, OpenADR, ISO 15118
Who talks to whom in EV charging: the vehicle, the charger, the CSMS, roaming partners and the grid, and which protocol covers each link.
RAG for Enterprise Documents: What It Takes Beyond the Demo
Retrieval-augmented generation is easy to prototype and hard to trust. Parsing, chunking, permissions and evaluation decide whether it works.
