Stekker API

Stekker has been developing applications at the intersection of mobility and energy since 2019. Stekker offers a unique solution to save costs and emissions, called Stekker.app. Since September 2020, third parties have been using Stekker.app for smart charging, which is continually expanding and refining.

It is applied in various use cases, both to optimize public charging for a CPO and for home charging by individuals. Stekker.app saves money and CO₂ emissions for the chain by delivering energy to EVs at optimal times, taking into account limitations of the charger, EV, location, and the preferences of the EV driver.
