EV Charging Connectivity
Secure, resilient connectivity for your charging network
Regulatory context: EU CRA, UK Smart Charge Points Regulations, ISO 15118-2 (mandatory Jan 2026), ISO 15118-20 (Jan 2027), OCPP 2.0.1, NIS2 for energy operators, UK CSR Bill for 300MW+ load controllers.
A compliance-intensive, distributed estate
EV charging is one of the most compliance-intensive sectors in connected infrastructure. Every charger processes payments, communicates with backends, and participates in grid management, deployed across distributed locations with no on-site IT.
- Every charger handles payment card data subject to PCI DSS 4.0
- Backend communication required for OCPP, grid balancing, and availability reporting
- Distributed locations with no on-site IT staff or fixed-line connectivity
- Firmware updates must be delivered securely and remotely across the fleet
- Multiple overlapping regulatory frameworks with audit and evidence requirements
Purpose-built connectivity for charge point operators
SIMSY delivers the connectivity, isolation, and compliance evidence that charge point operators need, without adding hardware or complexity at every site.
- Resilient cellular backhaul with multi-network failover across all four UK carriers
- Multi-APN traffic segregation for payment isolation at the SIM level
- Secure remote firmware updates without site visits
- Fleet-wide monitoring with anomaly detection across the entire estate
- No public internet exposure, all traffic stays on private infrastructure
- Compliance evidence generated automatically for audit readiness
What the platform delivers
Multi-Network Failover
Automatic failover across EE, Vodafone, O2, and Three. If one carrier drops at a location, the SIM switches to the next strongest signal without interruption. No single-carrier dependency.
Multi-APN PCI DSS Isolation
Payment card traffic and device management traffic run on completely isolated logical networks on a single SIM. PCI DSS 4.0 segmentation achieved at the SIM level with no additional site hardware.
Remote Firmware Updates
Push firmware updates securely to any charger in your estate without dispatching an engineer. Updates are delivered over the private network with full audit logging.
Fleet Monitoring
Real-time visibility across every charger in your estate. Connectivity status, data usage, uptime history, and anomaly detection, per charger, per site, per client.
Private Network
All traffic stays on private infrastructure. No public internet exposure means no publicly routable attack surface for your charging estate.
Compliance Evidence
Automated compliance evidence generation for EU CRA, NIS2, PCI DSS 4.0, and UK Smart Charge Point Regulations. Audit-ready documentation without manual effort.
