We built this board for internal use so our engineers can test chargers without needing a real EV most of the time. It simulates the EV signals only, including fault injection. The purpose is to test the real level 2 chargers without an EV.

Curious if anyone else would want one. We're happy to open source it once the final tweaks and testing are done. If there's enough interest, we might also sell it assembled with a 3D printed enclosure. Parts alone run about $150, and $85 of that is just the Type 1 J1772 inlet. The device can be remote controlled over WIFI.

We built the driver app most charging operators wish they owned. EVtivity Mobile is an open-source, white-label app for iOS and Android that runs on the same EVtivity CSMS that powers your stations. Drivers find chargers, scan a QR, start and stop a session, watch live power and energy, pay through Stripe, reserve a connector, and open support cases. It ships in six languages, locks down with biometrics and device attestation, and reskins entirely from one brand file: your name, colors, icon, and legal pages.

One codebase becomes your branded app. Stand up your CSMS, add your brand, build, and ship under your own developer accounts. Running your own single network is the free path under the Business Source License 1.1, the same license as the EVtivity platform. No revenue share, no rented storefront, no third-party name between you and your drivers. The whole thing is on GitHub, documented end to end.

A charging network is more than hardware and a billing engine. It is a brand your drivers carry in their pocket. With EVtivity Mobile, that brand is yours.

The EVtivity IoT Panel is a wall-mounted WiFi touch screen for your charging site: see every station, start and stop sessions, watch live power and energy, and drive the simulator. It runs on EVtivity's feature-rich REST API and is available now as a preview.
