Case Study: Optiwatt reduces EV charging costs with Smartcar

Reducing the cost of EV charging with Optiwatt

Optiwatt, an EV charging app, wanted to make electric vehicle ownership more affordable and sustainable by helping drivers schedule charging during off-peak hours. But as the company grew, integrating with more vehicle brands and accurately tracking each vehicle’s state of charge became a time-consuming bottleneck. To expand compatibility more efficiently, Optiwatt turned to Smartcar’s vehicle API.

With Smartcar, Optiwatt added support for 5 additional EV brands through a single integration and used vehicle data like battery level and charging status to automate charging schedules. Smartcar’s Connect flow lets drivers grant access with a few clicks, helping Optiwatt start and stop charging at the best times and focus on building new features. The partnership also supported Optiwatt’s green charging plan, with a goal of removing the equivalent of one gas vehicle from the road for every ten EVs enrolled.
