Real protocol stacks
For ISO 15118-20, ChargeLink acts as the charger (SECC) or the vehicle (EVCC) with real SDP, TCP, mutual TLS 1.3, V2GTP and native EXI, not scripted message lists.

ChargeLink Admin is the browser-based commissioning console for ChargeLink, included from the Professional edition. Installers and engineers verify an installation step by step, run charger or vehicle simulations, and keep every session as evidence.
- Guided verification: role, network adapter, protocol, certificates and pre-flight checks
- Live checklist, message sequence chart and log for every session
- Evidence with SHA-256 hashes, ZIP export and a printable report
- Profiles, engineering certificates and licence in one place
- Users with roles, API keys and a hash-chained audit log
- Every action also available over a REST API
- Installer signed by DEVlink AB as a Microsoft-verified publisher
REAL CUSTOMER APPLICATION / AUTOMOTIVE TIER 1
Real software.
Virtual environment.
On-time delivery.
An automotive Tier 1 verified its real EVCC software as a vECU in SIL. Easy integration with ChargeLink through the CLI helped the project deliver and test its software on time.
Read the customer story ↗WHY CHARGELINK
Both sides of the plug.
Evidence for every verdict.
Evidence you can defend
Every run produces a manifest with a SHA-256 hash for each file, plus integrity checks and redaction for sharing. Every artifact states what it does and does not claim.
Fits your bench
One CLI with JSON output and stable exit codes, a gRPC API for test controllers, and NI VeriStand plant coupling through an FMI 2.0 FMU.
ONE TOOL, SEVERAL ROLES
Choose the side
you need to test.
EVSE simulator
Play the charger (SECC) against your EVCC, OBC or vehicle software.
EVCC simulator
Play the vehicle, with a battery model, against your charger or SECC software.
Managed SIL pair
Run both roles against each other on one PC over loopback. Ideal for regression runs in CI.
PROTOCOLS & PROFILES
The right profile.
The right evidence.
Protocol names alone do not define support. Your evaluation confirms the role, mode and environment for your project.
ISO 15118-20 DC
DC charging with external identification (EIM), in Scheduled and Dynamic control. Charger and vehicle roles with mutual TLS 1.3, on a Windows SIL bench with NI VeriStand 2024 and a simulated power stage.
ISO 15118-20 runbook ↗ISO 15118-20 AC
Reference responses for engineering and test development.
ISO 15118-20 runbook ↗ISO 15118-2 · DIN 70121
Full DC sessions with ChargeLink as charger and vehicle, plus an EVSE reference responder (ISO 15118-2 also for AC), for engineering and test development.
ISO 15118-2 runbook ↗DIN 70121 runbook ↗IEC 61851-23/-24 System A
The CAN-based DC charging scheme. Station and vehicle roles with a simulated plant: on one PC, across two PCs over a virtual CAN hub, or on a physical CAN bus through a Kvaser CANlib channel.

CAPABILITIES
From one session
to a test campaign.
Protocol-first test campaigns
Test-case catalogues from the ISO 15118-2 and ISO 15118-20 test plans, for planning and traceability. Verdicts are backed by recorded evidence from your system under test.
Deterministic simulation & replay
Scripted ISO 15118-20, ISO 15118-2, DIN 70121 and TLS/PKI scenarios with a transcript hash, so the same run gives the same result.
Golden reference runs
Documented reference procedures, starting with a software-only ISO 15118-20 DC session, to prove your installation before you connect anything.
Automation
CLI with JSON output for scripts and CI, and a versioned gRPC integration API for test controllers. Local only, protected by a per-start access token.
NI VeriStand integration
Couple the charging session to a plant model in NI VeriStand 2024 through the delivered FMI 2.0 FMU, with a 500 Hz SIL timing profile.
Clear physical authority
Your safety controller, power electronics and bench adapters keep authority over physical actuation. ChargeLink never takes it over.
LICENSING

BEFORE YOU DECIDE
The practical questions.
Who is ChargeLink for?
EVSE, EVCC and OBC development teams, protocol and validation engineers, HIL labs and teams building repeatable charging tests. The starting point is one defined charging problem.
Can I start without a vehicle or charger?
Yes. The first golden reference run is a software-only ISO 15118-20 DC session on one PC. Follow the first-session guide.
Is ChargeLink a certification tool?
No. ChargeLink produces engineering and conformance-readiness evidence that helps you prepare for testing. It does not replace accredited conformance testing.
Which charging protocols does ChargeLink cover?
Full ISO 15118-20 DC sessions with external identification, as charger or vehicle. IEC 61851-23/-24 System A, the CAN-based DC scheme, runs in both roles against a simulated plant. ISO 15118-2 and DIN 70121 run full DC sessions as charger and vehicle, for engineering and test development. See the capability boundaries.
Can it work with our existing test environment?
ChargeLink is built to be automated: CLI with JSON output, a gRPC API and the NI VeriStand integration. Hardware, adapters, timing and safety responsibilities are confirmed for your setup during the evaluation.
How do we get access?
Start with a free 30-day evaluation licence, or a scoped technical evaluation on your own use case. Prices and commercial terms are quoted on request.
