evDash OBD2 is a live dashboard and diagnostics multitool for electric vehicles. Connect a compatible OBD2 adapter and view real-time EV data on your phone or Apple CarPlay. evDash is built to support as many electric cars as possible — if a vehicle exposes useful data over OBD2, the goal is to make it work. Main features: • Live EV dashboard with battery, power and driving data • Battery SOC, SOH, voltage, current and charging overview • Cell voltages, temperature data and 12V battery status • Charging graphs and trip energy statistics • Apple CarPlay support • Multi-car garage with quick switching • Service Menu with ECU scan, ECU versions and DTC tools • Pre-purchase battery check and battery health tests • Acceleration and brake tests • TPMS, CAN sniffer and diagnostic export tools • Remote Tuning to help add or improve vehicle support • Local logs, exports and optional remote upload evDash works with supported OBD2 BLE, BT3/SPP, WiFi, MFi/OBDLink, BMW ENET and evDash M5Stack relay adapters. Available data depends on the vehicle model, adapter type and supported vehicle profile. Some cars expose a lot of battery data, some expose only basic OBD2 data, and some are restricted by the vehicle gateway. Which cars are supported, and which data each one provides, is listed in the vehicle support matrix, updated with every release: https://www.evdash.eu/evdash/vehicles/ Reported anomalies — what owners observed after connecting an adapter or during diagnostics, with investigation status and precautions: https://www.evdash.eu/evdash/vehicles/incidents/ evDash Pro unlocks advanced diagnostics, multi-car quick switch, battery internal resistance calculation, cell health tests, graph exports, Service Menu tools and fullscreen diagnostic views.
