Method, apparatus and system for adjusting voltage of supercapacitor

摘要

Embodiments of the present invention disclose a method and an apparatus for adjusting a voltage of a supercapacitor, which are used to retard aging of the supercapacitor and extend a service life of the supercapacitor. The embodiments of the present invention include: the supercapacitor is used to perform power failure protection on a control chip that executes a service, where the control chip includes a cache Cache. The method includes: acquiring information that carries a system service volume; configuring a size of an available capacity value of the cache Cache according to the information; and adjusting a working voltage of the supercapacitor according to the configured size of the available capacity value of the Cache.
