What is the main function of energy capacitors in SRS?

The main function of energy capacitors in Supplemental Restraint Systems (SRS) is to provide power storage for a limited time. This capability is crucial in automotive safety systems, especially during a collision when rapid deployment of airbags and other safety devices is necessary. Energy capacitors can store electrical energy and release it quickly, ensuring that these systems function effectively at the critical moment of impact.

This temporary power supply is vital for the timely activation of the vehicle's safety features, which can significantly reduce injury risk during an accident. Essentially, the capacitors act as a backup power source, ensuring that the systems can still operate even if the main power supply is compromised or cut off during a crash.
