An important feature for the digitization of an energy storage device is its use in a stationary or mobile application. While wired data transmission is indispensable in a mobile application, a stationary application may still have some leeway here. Digitization means always being online. Depending on the application, a mobile data connection is necessary or a connection in the local network is sufficient. e.telligent offers solutions for both variants: mobile and stationary applications. The benefit for our customers: Your energy storage always stays online! By developing software for mobile devices (IoT_mobile), for an edge gateway or in combination, we create solutions for the digitalization of energy storage systems.
