B ATMAN is a technology able to diagnose the vital parameters of a battery such as the state of charge, the state of health and the state of operation. The heart of BATMAN is a unique artificial intelligence algorithm (ERMES). It was developed and patented in the brain Technologies labs. if inserted in an IoT architecture (edgecomputing), BATMAN can be run on computing platforms with limited resources (such as cheap microcontrollers) and self-adaptation capabilities

Battery status information can be displayed through a Bluetooth and/or a wired protocol (LIN or CAN). The data on which the diagnosis algorithm is based depend on the application. There are many versions of BATMAN, they may differ in performance and installation features.
