Conventionally, OBD-II ports are used by mechanics to gain access to a vehicle's diagnostic data. Today, groundbreaking systems like telematics are plugged into the OBD-II port, facilitating remote diagnostics and tracking vehicle performance. When it comes to electric vehicles, having an OBD-II port depends on the type of electric vehicle one owns. For example, electric vehicles like VW e-Golf that operate on the ICE vehicles' existing electronic platform have an OBD-II port. On the other hand, cars like Tesla don't have an OBD-II port but provide adapters that can be used as an OBD-II connector. Nevertheless, the Internet of Things (IoT) powers and controls remote diagnostics in EVs. Widespread connectivity fueled by IoT enables EVs to send data to the cloud in real-time and ML algorithms analyse the data. Tesla vehicles identify vehicle failures and automatically place an order of inventory needed or set a maintenance schedule for vehicle repair.
