Esco EV OBD Scanner

App

Read battery cells and save your own EV reports

Esco reads battery health, cell voltages, temperatures and fault codes from supported cars through an adapter plugged into the OBD-II diagnostic port. Its Windows app displays the readings and saves local recordings and PDF battery reports without a manufacturer account or connected-services plan.

You need a supported Bluetooth, Bluetooth LE or USB adapter; Wi-Fi adapters do not work. The author calls it early, and Stellantis testing is limited to a 2023 Opel Mokka-e and one session with a 2023 Citroën e-C4. The app only reads the car, but its calculated health ratings are estimates rather than a workshop battery test.
