Can A Bad Battery Illuminate The Check Engine Light? There are multiple ways that your battery can trigger the check engine light. The first way is that your battery is simply bad and cannot hold a charge.
A battery management system is both a supervisor and a caretaker of the battery—the system monitors and controls the condition of the battery cells and protects them from any potential threat. Creating a BMS is a multifaceted process—you need to design a set of subsystems at both hardware and software levels.
