The app also gives drivers insights into details like charge costs, gas savings, and charge efficiency for any period. Optiwatt claims customer data is secure and while users need to use their login credentials to register an electric model, the platform doesn’t store vehicle identifying information. However, it does retain an encrypted version of the authentication token used to communicate with the electric model. According to Donahue, the app has limited access to vehicles’ endpoints and can only start/stop charging and view the EV’s driving distance, which he says keeps the risk of cyberattacks low.
Optiwatt currently supports several EVs, including all four Tesla models, the Chevrolet Bolt EV, Ford Mustang Mach-E, Hyundai Kona Electric, Nissan Leaf, Jaguar I-Pace, Volkswagen ID.4, and Audi e-tron. It also works with plug-in hybrid vehicles (PHEVs) like the Ford Escape, BMW i3, and Volvo S90. The company’s website has a list of compatible models. Signing up for the Optiwatt program should enable drivers to save plenty of money on charging and also offer long-term benefits for both the grid and the environment.
