Purpose:

To guide you on how to check the Hybrid/EV battery cell voltage while using the Innova 7111 Tablet.

Introduction

Your car is an electric vehicle (EV), a plug-in hybrid electric vehicle (PHEV), or a hybrid electric vehicle (HEV), and for various reasons you want to inspect your battery pack state of health.
